EASY Downgrader for 3.71 M33 to 1.5 Without Pandora; Through Recovery Menu

[CaptainMorgan4]

edit

[Sonicboy 101]

Yes, finally something without the use of Pandora.
I'll definitely be saving this... Thanks for the post CaptainMorgan4. :)

[CaptainMorgan4]

No problem Sonicboy 101 I'm just glad to have my PSP back, and yeah and I hope others can use this to avoid time consuming Pandora procedures.

edit: Why hasn't this been moved to the PSP News Section yet, it's real and it works I've tested it.

[donleon21]

please don't lash out at me, but just checking-this will ONLY work for people who have had custom firmwares right? My psp was given to me by someone who knew nothing of the scene , and he had it upgraded to 3.52 official sony fw. so that's where my psp is at and i am looking for a way to either downgrade to 1.5 or to a good custom fw. so far i only know about pandora and was hoping for something more simple. So if anyone can help please do so , I appreciate it. thanks. :o

your only option is the pandoras battery

[DarthPaul]

Wow thanks Captain Morgan. I'm happy to know that your PSP is working again. :)

[liquid004]

Thanks a bunch Captain the downgrader work like a charm on my Fat PSP, i got frustrated with my CFW 3.71 m33, my psx games kept freezing even with the 1.50 patch. I never had the same problem with 3.52 M33-4 weird. Anyways thanks again now back to 3.52 M33-4!

you will need either pandora or use one of the game exploits which requires unpatched lumnies or GTA LCS

[donleon21]

you will need either pandora or use one of the game exploits which requires unpatched lumnies or GTA LCS


so i can do it using lumines? or is pandora truly my only option? thanks in advance.

[CaptainMorgan4]

No problems guys, yeah I just finished getting back on 3.52-2 (most stable IMO, CPU in XMB and etc) and ordering my emulators and fixing all my settings. Feels good to be back, and enjoy this downgrader. And to Donleon21 yeah this is for getting from 3.71 M33 Custom firmware to 1.5, not what you need.

[donleon21]

well thanks anyways i thought it would have been to good to be true for me, good app for those who can use it though, good work.

[jay_x_9]

does this downgrader work with psp slim with cfw 3.71 m33?

[CaptainMorgan4]

I have not tested it with the slim, try it, it won't brick your PSP anymore than it is so you got nothing to lose. I don't really see why it won't work, please try it and post your results.

[mike_jmg]

If only I would had it last week...
I haven´t been able to get my stuff together to try the unbricker yet, but I hope tomorrow hehe, also I´m getting a new PC on wednesday (at last, I bought the other one like 7 years ago, so you can imagine how it was, maybe I´ll restore it too so now we will use both here at my house)

Also might try this as well cause the unbricker will get it to 3.71M33, and I still want to hang around 3.52M33 a little longer, thanks for the app

[jay_x_9]

i can try it but my worry is that 1.50 fw won't work on psp slim, right?

[CaptainMorgan4]

Oh yea what am I thinking, my bad man I think I got lower the hits on this bowl here I guess.

[jay_x_9]

got that clear man... thanks

[smokepsp32]

thanks...will try this one...
DL in progress...

[merry3irwin]

one of the files is corrupted in the game folder on my memory stick and one of the files opens just to say the game could not be started. please help!!!!!

[smokepsp32]

tested...
it works for me...

now im back again in 3.71m33...


Smoke...

[legitnelite]

Wait so no matter what type of brick you get (on 3.71 M33) it can be fixed with this?????


No matter if it's a full brick you can still access the recovery menu? I know that's kindof what it says, but i'd still like confirmation =D

Anyway, I use to think recovery menu only worked for semi-bricks

No, this is entirely not the case. If you can't access the recovery menu, then you can't use this method and pandora is the only way that'll help.

[kund]

is it compatible with psp slim??

[Sonicboy 101]

Does this work with the 1.50 kernal installed?

[SpooForBrains]

is it compatible with psp slim??

No. The PSP Slim cannot run 1.5.

[Sonicboy 101]

Nevermind, I did it and worked flawlessly.
Now time to install 3.52 M33 again. :)

[CaptainMorgan4]

To the one guy who says it showed up as corrupted data, looks to me that your on a Sony firmware and not a custom firmware, this application is not for you. Well yeah if you are fully bricked and can't get to recovery obviously tis isn't going to work. But if you can access Recovery then this WILL work for you, and it's INCREDIBLY easy.

[Sonicboy 101]

Argh, I hate it when you install 3.52 M33 it takes ages to load up first time.
Scared me to death.

[ish420ism]

How come so many peeps brick their psp?? what are you guys doing wrong??
or are you bricking for fun?? lol. << I know that's not the case

[sammiesosa#1]

I'm om 3.71 m33+1.50cfw. What seem to be the problem. D-A would never release junk. Before u install 3.71m33 go 2 recovery and set homebrew to 3.52.
Make sure u have the rite 3.71.PBP along with the two files in the Update to the game folder. It load just like sony frame ware.
At the end press x then manually shut down ur PSP.
There u go 3.71 m33.
Now u can add the 1.50 kernel.
Finito!
No need for the downgrader this cfw is tha best.

[Supplicium]

Can I use this on a stock working psp with the 3.71 firmware? Do I still need GTA or Lumines?

[sammiesosa#1]

Can I use this on a stock working psp with the 3.71 firmware? Do I still need GTA or Lumines?

U need pandora battery & magic memory stick. U can only get recovery by having a cfw.
GTA or Lumines is 4 3.50 & lower.

[shadow_la05]

hey captainmorgan4 i tryied that downgrader but it did not work? i did what the read me told me2 do when i ran psp/game i found a update and a corrupted file or game please help me out thanx

[zaiser]

Thank you nice program

[CaptainMorgan4]

Shadow first go on your PSP and go the the left and look for system settings, from there go to system information, then see which firmware you are on. I don't think your on a custom firmware so this application isn't for you, but check your firmware then post back here.

[shadow_la05]

hey captainmorgan4 i check i have 3.71 but i use 2 have a lower firmware dont remmeber which thou. i upgrade it my psp twice b4 having 3.71. and what do u mean by customfirmware? and sorry 4 asking so many questions im kind of new2 all this psp homebrew and fastloaders

[Patrick23465]

I signed up just to download your file but I figured I should at least say thanks. Tested and working.

[watupgroupie]

Well isn't a full brick when you have no recovery menu, well i atlease consider it to be. I personally have fully bricked and it aint no fun and this can't fix it you have to get pandora. Never,ever let stupid theme flashers mess with your flash now kiddies it's a bad mistake and you'll regret it.

[CaptainMorgan4]

Yeah Shadow this is for 3.71 M33 NOT 3.71, your on a Sony firmware, you need to downgrade. If you want to be able to play emulators and stuff you need to get on a custom firmware. To do so your ONLY choice is to search and do the Pandora Battery procedure. After you downgrade to 1.5 using Pandora then you can go to a custom firmware, for instance 3.71 M33. This application just downgrades the custom firmware 3.71 to 1.5, it's not what you need. Thanks to all you guys who used this and enjoyed it, glad to hear it's of use to some people.

[shadow_la05]

oh ok so if i do the pandora battery i can use the emulators and stuff right. but does the pandorabattery work on any psp sony firmware? cuz i found the pandora battery but its requirements say i need a customfirmware such as OE,M33, WC or psp with the 1.5 original kernel.

You need a PSP that can run homebrew - or someone who has access to one - to create a pandora's battery and the accompanying memory stick (you need both for the process to work).

That page tells you how you can find volunteers willing to help you.

[CaptainMorgan4]

Figured I'd bump this because it's important and a useful app and maybe some people will see it so they don't ask a bunch of stupid questions.

[pur3skillzzz]

This is an EASY way to downgrade your PSP no matter how messed up it is to get it back to 1.5 without using the Pandora Battery and you have to run it through recovery so FULL BRICKS still can't stop this thing. It has to 2 easy steps, just install and run! Please read the README for short but valueable instructions and enjoy having your PSP back, I know I am!

i just got the new slim and light psp (black)

It says

System software: version 3.60

Will this be compatable for me or do i have to do it the hard way?:confused:

[CaptainMorgan4]

Please anyone with questions just refer to PAGE 1 and look at the FIRST POST, I added a "Will I Be Able To Use This" part.

[noob_riot]

I'm sorry, but I'm new at this. I'm planning to pick up a PSP slim today (first psp). I'm looking everywhere and just wanting to figure the best and easiest way to downgrade to play backups and do homebrew. Would this be fine, or should I go with Pandora Battery and Magic Stick. I don't know anybody with a PSP. Sorry for the noob-ness.

[CaptainMorgan4]

Like I said if you have a question REFER to PAGE 1 and READ the FULL FIRST POST, it will ANSWER ALL of YOUR QUESTIONS!

[gangsta1991]

WOooooW I got to say YOU ARE THE BEST MANN THANNXXXXXXXXXXX A LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOT i really mean it

I can't help but notice that his method is exactly the same as that posted by Ratatella in this post (http://www.dcemu.co.uk/vbulletin/showpost.php?p=526149&postcount=44) which was a direct response to a request from you for help.

I further notice that you repacked it, stripped out his readme, replaced it with your own, and removed all references to Samhain who provided the files used in the first place.

I further notice that you have neglected to credit either in your own news post.

Perhaps you might like to rectify these things?

Plagarising c*ck!

Plagarising c*ck!

now, now children, play nice....or I'll take your PSP's away and give them to Oxfam ;)

Seems like you "borrowed" some stuff, credit should be given where credit is due though.

Mike..

[CaptainMorgan4]

Oh yeah I found that from the boy and I just made it more easy with the files already in the folders. Then I just made a new readme, that guy that supplied that downgrader in that post didn't know who created it either, he just found it. That's why I didn't give credit to anyone, I'm not sure who made the downgrader but I just made it easier and more simple. You can give credit to whoever, it's just a recovery that just was modified to work for 3.71, not too hard to make. So yeah you can take it however you want but bottomline I really don't care I just wanted my PSP back.


edit: Yeah I just looked at that UPDATED version of his post, before he edited he didn't know who created it so I didn't list a name, enjoy downgrading people and remember read the first post if you have any questions.

[vijay]

first thanks for your replay...as you said... because i cant able to play many of my iso and cso,s in 3.71m33???i try every setting in recovery menu and xmb but wont work is there a bug in 3.71m33??yes the theme section is really great in this firmwe...so would you please tell me??why my some isos and cso wont work...:confused:

[CaptainMorgan4]

Make sure your using the correct NOUMD in the recovery like you said, set it to the Sony NP900 or whatever and try again. If that doesn't work try a converting your ISO's or something. I only use the Madden 08 iso and it works fine.

[vijay]

i try but nothing work..anyone tell me the setting of 007 from russia with love and need for speed most wanted5-1-0..if these work maybe other also???
3.71m33..:eek: :confused:

There's a site called www.pspiso.com that might have some people that could help you, that's basically all I can do to help you I don't know why your ISO's aren't working. (my Madden 08 works)

[AvengedSevenfold Fan]

this is not allowed on dcemu, it contains an official sony update.

[sneddy]

how do i find out if mines a 3.71 m33? as when i check the system info it just says version 3.71

[CaptainMorgan4]

No 3.71 M33 is a custom firmware THIS IS NOT FOR YOU, and to AvengedSevenfold Fan be quiet man stop messing with a good thing, snitch.

[Mr-S]

haha i bricked my psp running 3.52 installer through recovery...... then my computer chewwed up my memory card.... now i have 2 wait a week for a new card so i can pandora it... damn

[vijay]

hi captain i think i downgrade to 3.71m33-1.50..and then 1.50-3.52m33 then check the games not working in 3.71m33.what do you say..i downgrade psp through the pack???:confused: :confused: :confused:

[stfu]

:thumbup: downloading... what?

[CaptainMorgan4]

Vijay I'm not sure what your saying your typing is all messed up, but yeah you can downgrade from 3.71 M33 to 1.5 with this, you can try from 3.52 I don't see there being a big problem. To Stfu, if your downloading it and on your desktop it says corrupted data then you probably need WinRar to extract it, but if your putting it on your PSP and it's corrupt then you need a different program because this one is not for you.

[alexvander]

lol this wont help some of the people on this site



-Must Be Already On a Semi-Bricked 3.71 M33 PSP

what if im not on a semi brick will this still work for me? i just dont want to try it and end up with a full brick

[Sonicboy 101]

You don't HAVE to be semi bricked... I used it when my PSP was fine anyway and it worked like a charm.

[CaptainMorgan4]

Yeah this is MEANT for semi-bricked PSP's because the recovery menu is what it's run through and that's all you can access with a semi-brick. But yeah you can use this on a regular 3.71 M33 PSP too. To all the idiots out there looking to see if this runs on they're PSP, first check the FIRST PAGE for information but MAKE SURE YOUR ON 3.71 M33 CUSTOM FIRMWARE. This is NOT for JUST 3.71 SO STOP ASKING PEOPLE, why can't some of you just read?

[piplupzero]

whats a lumines is it a luner patch thing and where can I get it

[CaptainMorgan4]

It's a game or UMD for PSP that you don't need because you can use the Pandora Battery procedure, why do all the stupid people come to me?

[phidol]

i got 3.71 m33-2 ... can i use this with this cfw version? coz this might come in handy incase i brick my unit from customizing. i read in som forums that DG a unit on 3.71 m33 will result to bricking or messed-up idstorage...if im not mistaken and remember it right.

[CaptainMorgan4]

Yeah you can use this to go back to 1.5, have fun!

[dette]

Ummm
wait does this only work on a semi brick?
because i was thinking about going back to 1.50 then up to 3.52 M33 -4

[Asuki]

Captain, your the man!
I was afraid i'd be stuck with a semi/full brick after I fiddled with the resource folder, but now I'm back!

[pmh]

thanks this saved my psp :D i am forever gratefull :D

[Sonicboy 101]

Ummm
wait does this only work on a semi brick?
because i was thinking about going back to 1.50 then up to 3.52 M33 -4

Nope, it doesn't have to be semi-bricked.

[dette]

Ok sweet
i need to downgrade soo i might use this.. unless i just use pandora or the regular recovery menu...

[CaptainMorgan4]

Well this is the easiest way to downgrade so I suggest using this, and to all the people your welcome, I was very happy to get my PSP back too so I understand you.

[dette]

well
i just used pandora....
i think its probably safer

[CaptainMorgan4]

Safer? There isn't a way to brick using this downgrader, this way is simpilar though all you do is put 2 files in the GAME folder and then click X in the recovery menu and your back to 1.5 in less than 2min. Glad to see your back but I think you should have used this but it's cool.

[rahman530]

thakn you so much this is going to be helpfull, yesterday i just got my pSP to 3.52m33-4 and earlier today i upgrade to 3.71m33-2 not knowing that XMB themse for 3.52 dont work for 3.71, i semi-bricked it, so thank you very much

i need help fast.I have a 3.71 brick psp and I need a site wear I can get a downgrader

[CaptainMorgan4]

Are you on 3.71 M33 or just 3.71? If you are just on firmware 3.71 you need to do the Pandora Battery process. That's the only way to recover from that firmware, unless your on the M33 3.71, in which you could use this. Good luck, just go google Pandora's Battery.

[factor remix]

hey captain... do youknow if it works in a 3.71 m33-2?

I hate this m33 firmwares, I just want to go back to 3.03 OE-C

[Super6mix]

yeah well it bricked my psp.... GRRRRRRRRRRR... damn thing just turns off during Flashing... WTF.... thisn is my first Brick..

Thank you...
>:(

[CaptainMorgan4]

No problem glad I could help, this program was obviously used by someone who doesn't know what they're doing. They didn't meet the proper requirements so he shouldn't have used this program but instead he did and now he's bricked. I'm happy to brick anyone who is stupid enough not to read and see if what they are doing is right for them. Super6mix you obviously weren't on 3.71 M33 or you didn't follow the easiest instructions ever. No one before you has bricked and judging by this being your first post you either are lying or just an idiot, take your pick. Either way I'm happy to have another person who doesn't know what they're doing and is too lazy to try to figure out stuff be bricked, keeps em away from annoying us regulars.

[slowpy]

well this work on 3.71 m33-3? plz reply

[CaptainMorgan4]

Yes go ahead, should work no problem.

[scumbo]

Hi,I am new for this staff.
I have got a psp with 2.71 se software and after I removed the battery for a week the psp bricked.I can still enter the recovery menu but with the files in the proper place I still cannot load the 1.5 software. After 30sec the psp goes off and there is no action of led's flashing.

[CaptainMorgan4]

You need Pandora's Battery for that scenario, good luck and google is your friend.

[quiksilve]

Thanks captainMorgan, you da man for the file.

Got my favorite emulators running again with this file, after switching back to 3.52 m33-2:thumbup:

[scumbo]

CaptinMorgan4 ,Can it be done with only one original battery and one memory stick

[CaptainMorgan4]

Yes all you need to be able to get this to work is to be able to access the recovery menu, doesn't matter what memory stick or battery your using.

[scumbo]

Yes all you need to be able to get this to work is to be able to access the recovery menu, doesn't matter what memory stick or battery your using.

But i can access the recovery menu but when I try to load the EBOOT nothing happens but after 20 sec the psp goes off.

[CaptainMorgan4]

Are you on 3.71 M33?

[dali360]

hy.i am new in psp world, and i have firmware 3.71.i want to downgrade to 1.50 but i dont how to downgrade and i want to know is there posbilty that my psp block???please i need answer!!!!!!!!

[cal360]

Yes there is, you need another PSP that can already run homebrew though. Just quick search pandoras battery. It is possible with all PSPs don't worry.

[scumbo]

Are you on 3.71 M33?

No I am on 2.71se

[Choby]

:confused:
I HAVE A QUESTION:

I am on 3.71M33 [NOT BRICKED]

I want to downgrade to 1.5 so I can then upgrade to 3.40o-ea.

My question is: Will this downgrade work for an Non-Bricked 3.71 M33? :confused:

[Sonicboy 101]

Yes.

[Choby]

How do you know?

[Sonicboy 101]

I've used it before on a non-bricked 3.71 M33 PSP.
It works as long as you know what you're doing.

[Choby]

What about 3.71 M33-2?

[Sonicboy 101]

Yeah, it should be OK.

[Choby]

Okay, thanks pal.

[Choby]

Damn! I just read on his first post it says:

-Must Be Already On a Semi-Bricked 3.71 M33 PSP

Gonna have to find another solution.

[Sonicboy 101]

You don't HAVE to be semi bricked. I already said that lol. Look here:

Yeah this is MEANT for semi-bricked PSP's because the recovery menu is what it's run through and that's all you can access with a semi-brick. But yeah you can use this on a regular 3.71 M33 PSP too. To all the idiots out there looking to see if this runs on they're PSP, first check the FIRST PAGE for information but MAKE SURE YOUR ON 3.71 M33 CUSTOM FIRMWARE. This is NOT for JUST 3.71 SO STOP ASKING PEOPLE, why can't some of you just read?
Captainmorgan please update the first post saying this.

[T4nks]

I installed it on my psp, and ran the installation, but it still says i have firmware 3.71 Have I done something wrong?

p.s it goes on the psp startup screen then a message pops up saying "This game could not be started. (80020148)

[SHR]

Can I just check that I'm doing this right?

It never seems to have any effect.

I hold R and turn my PSP on to enter the recovery menu. I toggle the USB on, and copy the two folders into PSP/GAME. Then I use "Run program at /PSP/GAME/RECOVERY/EBOOT.PHP.

Then the screen goes dark, and the top light on the left flashes orange a couple of times. Then the PSP boots as normal, and I go to check the firmware, only to find that it's still 3.71 m33-2.

Any ideas about what's wrong?

Make sure you have the file(s) placed in the correct folders and that the folders are labled correctly and placed in the right directory on your memory stick pro duo.

This is for 3.71 M33. Read the title.

[ice_storme]

Just a quick question. If this proess was to somehow brick your PSP, could one be able to restore one's own backup of his or her NAND to the motherboard of the PSP to return the system back to it's previous state? Exactly how difficult is it to restore a NAND on your own PSP using either Pandora Battery with a logical restore or Dark_AleX's Desperatar del Cementerio V3 with a physical restore? What is the difference between the two types of restores? (Logical & Physical) I know how to go about backing up the NAND for my unit, that much is simple, but how would I restore a NAND dump from NAND-DUMP.bin on the memorystick using either process? Is it even safe? I would greatly apperciate anyones feedback on this mattter. Thanks.

[radwano]

i have 3.71 m33-3 is it stil posible

[Vampiric Inuyasha]

I would assume so Rad. Before coming across this thread I posted a thread about a problem I have which people thought wasn't about the firmware. Anyway I thought upgrading to -3 would fix my problem but it didn't, hopefully this will solve my problems. I just wish people would read the first post, and read that if your firmware doesn't have M33 at the end then this won't work for you.

[CaptainMorgan4]

This will work for any fat PSP that is on 3.71 M33 bricked or non bricked.

[torrvakhri]

Hey thanx captain, it WORKS.

[elboricua]

will it work if you have the 3.72

[CaptainMorgan4]

No you must be on M33, stop being an idiot and READ the first post.

[darter183a]

Hello I am trying to get gpSP to work I have BIOS and config_text. I have my rom in the gpsp file and win I start it crashes. I'm using 1.5fw. Could you guys please provide answers.

[CaptainMorgan4]

Wrong thread please don't post spam here.

[mystah_danger]

wow thanks dude. I'm new to this psp hacking thing so yeah really appreciate the help.

[gamer193]

im a complete noob and i was wondering were do u put the stuff and how do u do it.

thanks

[CaptainMorgan4]

Just download this and read the file that says, and check this because it's confusing READ ME! People come on stop being idiots, and secondly stop using these stupid ass words like noob. I mean are you a virgin and just want everyone to know it? That word is so stupid and I'm so tired of hearing it, like you guys are completely oblivious to how stupid you sound when you say it. Anyway I have to watch my Packers beat the cowboys tonight so yeah lets go PACKERS!

[jag007]

having problems downloading the zip file 3.71 M33-1.5.zip is there another link i can use for the download?

[pmurphy]

Thanks CaptainMorgan4 !!!

Your downgrade files are exactly what I needed. I'm finally back to good ol' stable 3.52 M33-4 and staying far far away from 3.71 M33-2. My homebrew, PSX games and everything else is back !!!

Thanks again you ARE the Captain !

[shawn23]

It worked for me! got my PSP back to 1.50
THANKS!

[Necro Star]

does putting nand on your memory stick or dumping to flash dangerous. I want to keep the nand but dont want to risk bricking my psp slim. By the way, has anyone bricked converting their slims to m33-2?

[thesvart]

yes! now I can start hackin from the beginning again... :thumbup:

[Ganon007]

Thanks a lot man. Exactly what I was looking for. Worked like a charm! :)

[CaptainMorgan4]

No problem glad I could help, I was so happy to get mine back so I know the feeling.

[Tithe AD]

Hi,been a silent hacker since the start and have been away from the scene for a few months.Upgraded my oe to 3.71-3 everything game and emu wise seems to run fine and i even used cxmb theme via flash0.
Why does everyone want to downgrade again?Is there something i have missed?thx.

[PSP68]

It worked! thank you!:thumbup:
And Tithe AD, ive flashed my psp twice and both times i cant access to xmb, only recovery, and i even dont know what im doing wrong!

[hellboythecool]

thanks CaptainMorgan4!!! but i would like to ask you if 3.71m33-2 can make pandora battery???

[ellswortha101]

I do not want to offend anyone, but if someone is smart enough to get M33 on their psp they would know how to do this

[ellswortha101]

thanks CaptainMorgan4!!! but i would like to ask you if 3.71m33-2 can make pandora battery???

--------------------------------------------------------------------------------

Yes indead it can, but if you haven't already download the 1.5 kernal plugin get it here
http://exophase.com/files/psp/150kernel_addon2.rar
THIS IS IMPORTANT IF U DONT HAVE IT

[SuicidalLoveNote]

my 3.71 m33 was glitchy, so i decided to try your thing. It downgraded, although now, the screen stays black when i turn it on. Please help me.

[CaptainMorgan4]

You are bricked, can you access the recovery menu at all? If you can just try this again and you should be fine, not sure what went wrong. Make sure this time after you downgrade you go straight to the system settings to configure your PSP back, sometime that can be the issue, try again and tell me what you get.

[jimzydoodah]

THANK YoU SOO MUCH!!! I really screwed up my 3.71 and didnt save the flash! this has saved me!!!

[help plz]

will this be able to restore ur flash0 cause i accidentally deleted a few of my programs

[CaptainMorgan4]

No there's nothing for that.

[Romanation]

Any ideas if this work on a 3.71m33-4

Trying to get my emulators to work and having no luck so gonna try 3.52m33

Any replies appreciated ;)

[Romanation]

Yes. It does. I tried it :)

Now on 3.52m33-4

Thanks CaptainMorgan for the file ;)

[CaptainMorgan4]

No problem, yeah this will work on all 3.71 custom firmwares.

[klone111]

my psp is being gay an it only runs the red file called x.zy and when i run it it says game could not be read

[!llumInatI]

hi how can is downgrade my psp with this i have a normal havent done anything, only upgraded it with the original psp updates to the newest till now!
my psp is the japan version in white!

[Super6mix]

you can't... you will need Pandora..
find a hack PSP with 1.50 or CFW. then make the Pandora battery. then you will be able to downgrade your PSP..

sorry that's the only way..

[vijay]

hi captain how are you..any new psp firmware like 3.71m33-4 or 3.80 etc:thumbup::thumbup:..:thumbup:;)

[vijay]

any downgrader for 3.71m33-2 to 1.5....:rolleyes:

[CaptainMorgan4]

Read the first post this will downgrade any 3.71 M33 1-4. 3.80 no, maybe when the M33 one comes out, we'll see.

[Steel_Snake]

I'm having a problem, I run the program but it says it can't find UPDATE.PBP?

[Steel_Snake]

ok when i look in the file while in the ZIP folder i see the update.pbp but i can't seem to move it, as if it doesn't exist. When i try to extract them it says the file UPDATE.PBP is corrupt.

[CaptainMorgan4]

Try re-downloading it, or download it from a a different computer, there's just a corrupt file your getting. That link on the first page was just updated last week so it should be fine.

[lollero]

I was halfway into making a pandora battery when I found this here thread, a nice little package you've there, mang. Saved me a lotta trouble.

Oh yeah, the update.pbp was reported as corrupted by winrar, so you might wanna look into it. peace

[vijay]

;):D:rolleyes::rofl: HI CAPTAIN WISH YOU AND ALL A VERY VERY HAPPY NEW YEAR...THANK,S FOR YOUR SUPPORT...:thumbup::thumbup::thumbup:

[CaptainMorgan4]

I just tested the download myself and got no issues, can anyone else report if the update.pbp is corrupt for them? I refreshed this link last week I don't see what the problem is.

[dette]

Yes the UPDATE.pbp is corrupted just download a normal 1.50 update pbp and rename it and you will be good

[CaptainMorgan4]

Okay I fixed the file again, but strangly it wouldn't let me upload it for a link in the post even though it's 13mb. So I replaced it with a more secure rapidshare link, if anyone has problems please tell me. Enjoy downgrading guys and getting those PSP's back.

[mrdeamz]

thanx for this man!!! i got a semi brick and my gf's psp wouldnt run the pandora program so i thought i had to drive across town to get my cuzins psp but ran into this and it saved me thanx a butt load man!!!

[jinpy]

:/ it keeps saying that the download session is invalid and wont work :(. Can someone help?

[jinpy]

do you have an alternate link? rapidshare seems to have something against me or sumthin.

[CaptainMorgan4]

I tried again to upload the file onto here on DCEMU but it failed again for some odd reason, so I added another link, hope that helps you.

[jinpy]

Thanks so much! Im so glad to be able to play my psp again:thumbup:

[Archadder]

hmmm... the files are giving me some grief.
while flashing, it says that i have an error 800100 loading lflash_fatmat.prx and ipl_update.prx, then its says it has an error opening update/pbp then at the end tells me that the psar is corrupted, or something. anyhow, im just trying to figure out whats going on and seeing if i can get anymore help.

[h4rm337]

would this happen to work on 3.80 M33-4?

[CaptainMorgan4]

Archadder try downloading the file again, maybe from the other link and then try again (make sure you delete the previous files off your memory stick before trying again). H4rm337 this should work on 3.80 M33, give it a try and tell me your results, I don't see any reason why it won't work.

[HOSTMARCEL]

how do i load it in recovery?

[HOSTMARCEL]

iam in recovery but cannot find it i put it on psp/game/update

[h4rm337]

ill try as soon as i can

[CaptainMorgan4]

Hostmarcel please check to see if you did everything right in the README file that came with the package, and h4rm337 thanks and please tell me your results. Hostmarcel when you go to recovery just click down twice till you get to the option that says "Run program at /PSP/GAME/RECOVERY/EBOOT.PBP" then click X on that option to run this downgrader.

[HOSTMARCEL]

i did and the screen freeze black what my bro done is he downloaded a costum theme and had to make space in flash0 so he deleted all files and pasted the theme files in there and when he tryed to load it froze so now he ended up with a bricked psp can he still use the downgrader and if so what am i doing wrong and thx alot for all the replys ;)

[HOSTMARCEL]

i found out i had to rename the folder UPDATE to RECOVER than it loaded and said doing preperation then it froze -.-

[CaptainMorgan4]

Listen read the FIRST POST again and make sure you reach all the requirements and that you have a PSP1000 (fat). Then read the entire README file again and just follow it CAREFULLY, your doing something wrong so find out what it is, I can't help you anymore then that.

[HOSTMARCEL]

i do have a psp fat that had 3.71m33-3 firmware i did read the RED ME file i do have all requirements

i will try and do again thx for your help ;)

[holla2k]

Not working for me. I have a 3.71m33-4 semi bricked phat psp. I can access recovery menu. I used another psp(ofw) to add the recovery and update folders to the ms. I then went to recovery menu and tried to run the eboot but all i get is a black screen.


I somehow messed something up in the flash0. Thats why i have a semi brick. I downloaeed a flash0 back up but i still get a blank screen whenever i try to start up my psp.

Like i said i can access recovery menu. I can't make a pandora battery because i dont have another cfw enabled psp. Any help?

[deco147]

tryed this on 3.80 m33-4 didnt work

just lots of words like panic and stuff lol

psp still worked fine after tho

[CaptainMorgan4]

Holla2k try putting the files on the memory stick from the recovery menu (use the toggle USB option) and just hook your PSP up to the PC like you would normally. Then just try again, please people make sure your doing everything right, this downgrader works so get it to work for you.

[philcamlib]

i got it to work throuch the recovery part

--all it is -is just papupdatever xyz but through recovery and its way better

it worked on 3.80m33-5

:D

[chuchugaga]

I have 3.80 m33-5 and when I run the program from the recovery menu I get the error "The game could not be started. (8002013C)" which according to another site means "Library not found."
Help. :confused:

If you have a fat PSP (PSP 1000) then you need to install the 1.50 Kernel Addon for 3.80 from Dark_Alex first, and then enable it through the recovery menu...

That said, so far I have only had success with the one in the UPDATE folder (but only after adding the ipl_update.prx & lflash_fatfmt.prx files to the folder) - not too sure what I must be doing wrong as I cannot get it to run under the RECOVERY menu (from the RECOVERY folder), the screen goes black, the ms flashes briefly and then nothing...:confused:

Still it does work under the update folder so I have actually got a working 1.50 OFW PSP :thumbup:

Yeah when I run it from the XMB i get an error saying missing ipl_update.prx & lflash_fatfmt.prx files. So do I get those two files or the kernel add-on or what?

[boo128]

You definitely need to have the ipl_update.prx & lflash_fatfmt.prx files to run this under the update folder from the game menu from the XMB (the 1.50 kernel addon does not seem to be a necessity tho - just tried it without...)

Edit: Ok, you do need the 1.50 kernel addon if you do it through the recovery menu, just not if you can get to the XMB and run the PSP Update ver X.yz file under the game menu...

[CaptainMorgan4]

Well I've updated the first post alot from people's conversations and issues so if anyone is having trouble please check it out.

[chuchugaga]

I can run the update through the XMB, so where do I get the ipl_update.prx & lflash_fatfmt.prx files and where do I put them?

[boo128]

You can get the prx files here (http://mihd.net/cnsebp) and they need to be installed into the \PSP\GAME\UPDATE folder

As I said earlier, I still have not had success in getting this to work from the recovery menu - just the XMB...

Works brilliantly, thanks!
And in completely unrelated news, is it safe for me to install 3.71 m33 directly on 1.5?

[CaptainMorgan4]

Yes but then you have to do 3.71 m33-4 after that, why not just go to 3.80 m33.

[chuchugaga]

Because I already had 3.80 m33, I needed 3.71 m33-4 because I wanted to watch YouTube on my PSP and PSPTube didn't work on 3.80, it said "PSPTube for CFW 3.71."

etc.

[CaptainMorgan4]

PSPTube works on 3.80 M33, get the 1/14/08 version of psptube it works fine on my 3.80 M33.

[chuchugaga]

PSPTube works on 3.80 M33, get the 1/14/08 version of psptube it works fine on my 3.80 M33.


OR this new version released 27th of January, lemme try that first.
http://dl.qj.net/PSPTube=20080127=PSP=Homebrew=Applications/pg/12/fid/15782/catid/151

Edit: okay scrap that, that's only for the slim PSPs.

[chuchugaga]

Okay listen to this:

PSPTube didn't seem to work on my CFW so I downgraded my PSP 3.80 m33-5 to 1.50 after much googling to find a way without Pandora, then I upgraded to 3.52 m33, then 3.52 m33-4, then 3.71 m33-4, and reran PSPTube which still didn't work @ I couldn't find a place to type my search in, which was the earlier problem. Then I realized that I was in the Favorites folder and all I had to do in the first place was to press select to switch to YouTube and then enter my search.
Brilliant.

[boo128]

Has anyone had success in running this under the Recovery menu on 3.80 M33-5 yet?

If so please can you advise of which files need to be in what folder, as I still have not had success in running it from there (I can run it perfectly fine from the XMB with the added prx's quoted above)

If it is any help, I am currently running 3.80 M33-5 with the 1.50 Kernel add on (it is a Phat PSP TA-081)

[CaptainMorgan4]

I hate to sound rhude but why does it matter if you can just already do it from the XMB?

[boo128]

Reason because, if I get a semi-brick, I will not be able to get to the XMB - I just wanted to be lazy and have an alternate option to the Pandora for downgrading if things go wrong...

[bern2707]

this is a good thread, but i cant get it working, On 3.80 m33-5, Ive done the 3.80 1.5 addon, and then run this program, I get a lot of errors and at the end it says press x, And nothing happens, i have to take the battery out, and put back in, then im still on 3.80 m33-5, Im trying this on my fat psp,

Looks like boo128 has the same prob, Does it just not work on 3.80 m33-5 ?

[CaptainMorgan4]

No it works just make sure your files that you downloaded from here aren't corrupt or something. Just review everything carefully and try again, if it doesn't work for you try boo128 XMB way.

[bern2707]

Ive never heard of boo128 (XMB,) I managed to find it and download it, and get seplugins and a readme tgt file, If thats correct, Where do i put these,

[CaptainMorgan4]

No Boo128 the guy that you mentioned in your last post. I was trying to say use his method, from doing this downgrader from the XMB. I suggest you PM him, and see if he can help you out.

[bern2707]

Thanks, I meant what does XMB stand for, Ive tried a few ways to downgrade, All failed, CHEERS ANYWAY

[No_one_in_particular]

XMB is the menu-system on the PSP. So when you're scrolling left or right, and eventually up and down to choose whatever on your PSP, that's using the XMB.

[mohis]

Does this work with the new Custom Firmware released, 3.90M33? Thanks

[boo128]

@mohis No this just shows up as corrupt data under the 3.90 M33 CFW (tested on a Phat with the 1.50 Kernel Add On installed)

[mohis]

@mohis No this just shows up as corrupt data under the 3.90 M33 CFW (tested on a Phat with the 1.50 Kernel Add On installed)

THANKS

[boo128]

Update
This will work on the 3.90 M33 firmware with the 1.50 Kernel Add On installed, but ONLY from the XMB - to make it work you need to copy the prx files (from the post on page 21 of this thread) into the PSP\GAME\UPDATE folder first.:thumbup:

Still not had success as yet to make it work from the Recovery menu though...:confused:

[badboybungi]

erm so could i use this on 3.90 m33 because half the game i play on 3.90 m33 don't work but works on 3.71 m33 when i first had it

[vijay]

its a long time ..hope you fine....;):cool::thumbup:

[CaptainMorgan4]

Haven't killed myself just yet.

[trun21]

where can i get the 2 files?

[trun21]

i have a semi brick psp that wont boot up but still can go to recovery.but will the 2 files work?if they do,can you tell me where can i get it.i have a 3.71m33-2

[trun21]

Thanks Cap

[radioactivemario]

It's not running. I copied the files to the GAME>RECOVERY folder and it says "The game could not be started. (8002013C)" Please, I need my psp, it's really one of the few things I have that I can talk to my friends with. I copied all of the files correctly, and it still won't run. I'm using CFW 5.00 M33-4. I need help.

[chikin]

dude, u r the best. this saved my psp. thnx man
