Downgrader for 2.80, 2.80 with TA-082, and HEN-D for 2.80 released!

Via noobz

A lot of people have asked for a downgrader for v2.80 that's both safe and simple to use. Well, the Noobz aim to please - we've merged and ported Dark_AleX's generic downgrader and TA-82 downgrader, to bring you what is probably the best v2.80 downgrader! :)

And as a bonus, we made this possible by porting Dark_AleX's HEN-D release to firmware v2.80, which means that if you don't want to downgrade yet, you now have a good platform for launching kernel-mode homebrew.

Why should you use this downgrader? Well, the major advantages are:

• safety - this downgrader has plenty of safety checks in place to try to avoid accidental bricks (but read the warning below)
• convenience - because this downgrader works with an official firmware EBOOT.PBP file, and includes the TA-082 idstorage changer and HEN files, you don't need any other files (except for a v1.5 update EBOOT) to perform the downgrade. No more finding a v1.5 owner to get dumpfiles!
• latest TA-082/086 support - the bundled TA-082 registry fixer includes the latest fixes to make sure that USBHost support won't be messed up.

So, let's not hang around, how do you use this to downgrade?

1. Install the HEN files, by following the details in the readme.txt file.
2. Test that HEN is working fine, by running one of the bundled sample applications - e.g. the cube demo.
3. If you have a TA-082 or TA-086 PSP, run the "TA082 IdStorage Changer", via HEN, to patch your registry before downgrading.
4. Get a copy of the v1.5 upgrade EBOOT (e.g. from here) and copy it to the /psp/game/UPDATE/ folder on your memory stick, as UPDATE.PBP.
5. Start the"PSP Update ver X.YZ" program via HEN, and follow the instructions.
6. Congratulations, you now have a v1.5 PSP! :D

WARNING - Like any downgrader, there is always a risk of bricking your PSP. We have done our very best to make this as safe as possible, but by using this program, you accept all responsibility for any problem that may occur. ALWAYS READ ALL THE INSTRUCTIONS CAREFULLY BEFORE USE.

Full credit is due to Dark_AleX and Mathieulh, who generously provided code and assistance during porting of both HEN and the generic downgrader, and HarleyG, who was instrumental in much of the research that went into that code.

One final word - this shows what is possible when developers ignore artificial boundaries and egos and help each other out. We hope to continue to work closely with Alex and Mathieulh in the future, to keep the homebrew scene moving forward like an unstoppable juggernaut :D

Awesome, But be careful with your psp guys. There is always a chance with TA-082 and Regular psp that you will get bricked.

Like it says in the big red text ;)

Good work to all of you guys....

Great news for people stuck at the minute. Nice! :D

Also good to see Fanjita and Ditlew bringing out more releases (aswell as DAX Helping that is) ;)

my first nooby moment in a long time:

ive got a friend with a 2.81 psp, possibly ta-82. and i am thinking this wont work...but i never thought there was a huge difference between 2.80 and 2.81..
... is there a chance this will work or not.

good job ;)

goddamnit. everytime i see 2.80 downgrader news, i always think its a 2.81 downgrader >.<

is there any news yet of the progress or something?

i guess ill await a very sad look when i go to uni tomorrow.

soon i guess...

at least im on 3.03-OE-B...HA

Awesome! Nice job guys! :thumbup:

The noobz team is incredible!
Almost as good as Dark_AleX!

No, 2.81 downgraders wont work until we find an exploit for >2.81 PSPs. we wont make any "progress" until then ;)

Great work!. Glad to see devs working together and helping each other out. One big happy family, lol

:) cool for brickofobics.

Nice release!. :)

I feel your pain. But try to be patient. The PSP scene obviously is not dying down so as long as we keep moving forward and growing strong I'm hopeful that some 2.81 exploit developments will emerge.

QUESTION FOR FANJITA:

If Fanjita happens to come by and see this post or if anyone else wants to answer, that is fine.

If you are not yet aware, the current downgrader for 2.71 TA-082 corrupts something with IDstorage and USBHost support. Maybe a couple other things as well.

So with that said and now this new downgrader, do you recommend upgrading 2.71 TA-082's to 2.80 and using this downgrader instead?

Wow, just to let ya know it works

I downgraded my 3.03 Oe-B psp and upd to 2.8:eek: :eek: just to test it for another forum:D .It works fine and is a little easier then the DAX one. :thumbup: :thumbup: :thumbup:

i have to say - its about time all the greats got together - even if unnofficially - to release something truly great. so congrats, well done and thank you.

Nice job guys, this is a much to be proud of success.

AH, noobz are the BEST. Way to go. Simplifying the actual 'noobs' lives so the don't complain when they dg and brick.

Next step: exploit 2.81!

I have a PSP purchased in Canada, model PSP-1001k, I think that is the original. My question is, will this safely downgrade this model as well as the TA-082?

they are talking about this

http://pgrevolution.com/wp-content/u...a-082_spot.jpg

open your umd case and look PSP-1001K is irrelevent last i heard :)

Thanks for the response, but there is absolutley no number in that area of the UMD slot. I guess I'm left with asking if this is possible to figure out based on the model and year. Also, does it really matter so long as it's an older PSP?

No, it doesn't matter.

If you have a PSP-1001k you are good to go! Just make sure you are currently running 2.80 firmware (I assume you already checked this in System Information) and this should work fine.

Remember, this is for 2.80, and 2.80 with TA-082!

So don't worry if you don't see the IC1003 in the UMD slot.

Tips to remember:

1.) Plug in AC Adapter
2.) Make sure your battery is charged to at least 75% capacity
3.) Not always necessary but doesn't hurt to format your memory stick

Thank you seriously, these were my first posts, so thanks for making things easy. I'm going to try and downgrade tonight, and I'll post my findings in the morn. Thanks again for all the other night owls out there.

Thank you all. Seriously, I got this psp way back and upgraded it right away to 2.5x wihtout even thinking about it. Now, after so long I can finally enjoy some real homebrew. Downgrader worked like a charm even though my heart seemed to be going crazy for that one minute. Cheers! And now, if I can get up the courage it is on to the custom firmware.

2.81 please

oh and patrick - custom firmware rocks. i got one on that and it is amazing.

i now need 2.81 cracked though as i just bought my wife a pink psp and it is 2.81 :(

You are very welcome. I'm glad things went good for you and that you are not a part of the PSP homebrew scene. There is nothing I like seeing better than new people discovering and joining the scene.

I would definitely upgrade to 3.03 OE-B if I ware you. It is well worth it. You will have to upgrade to 3.03 OE-A first and then run the OE-B update.

This TA082 idstorage patcher includes fixes for all of the currently-known problems with the idstorage hacks, so as far as we know you should no longer have any USBHostFS-related problems.

If you want to be really safe, you could use a NAND-dumper app (there's one included in the HEN package, for instance) to grab off a copy of your flash before you run the idstorage patcher. That way, if any further problems are found with idstorage hacking, then you would at least have a chance of being able to recover the original data to repair it.

The downgrader auto-detects TA-082/086 and will tell you, then won't let you go any further until you do the right steps, so you don't need to worry too much about working out the version for yourself.

wouldn't it be better to make a 3.0 downgrader first? cus then it would just require updating and downloading and more people will be able to use it.

Thanks n00bz, was planin on downgrading with the 0okm downgrader for my mate but id rather use this safer version so thanks for your hardwork. Nice to see people in the scene working together and maybe if dax n co joined your team you would be like the uberist ever, but it doesnt really matter because if dax is this unselfish in future we may get a 3.03 downgrader...prob not soon tho. Source is a very nice thing lol.

THERE IS NO KNOWN EXPLOIT FOR 2.80+ FIRMWARE PSPs.

Without an exploit that allows access to the Kernal of the PSP there can be no downgrader.

Therefore it is currently impossible for anyone to make downgrader, its not that they don't want to or can't be bothered........

I've installed HEN, but I'm not going to use the d/g for a while, so I tried loading some homebrew with it. But none of it works, except the stuff bundled with it. All the homebrew I had previously worked with xLoader, and i tried putting unpatched versions on as well, but it all comes up to the blue screen then back to the XMB with the message 'Game could not be started', just as if you were to try to load it without any homebrew enabling software. Any help?

I just downgraded, if a 2.80SE Firrmware Comes out i'll upgrade.

... Why not upgrade to 3.03OE? There will never be a 2.80SE firmware.

Sure, tell me how to run unsigned code on 3.0 and I'd be glad to.

I usually find it's better to the possible stuff first. Impossible is nice, but usually takes a little longer.

Gotta love that attitude! Nice work as always.

If you flash HEN-D to your psp, and update afterwards, could this brick your psp? Just in case I would have to update (sony has to give an extremely good reason to so).
