THIS IS IMPORTANT IF U DONT HAVE IT
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.
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.
THANK YoU SOO MUCH!!! I really screwed up my 3.71 and didnt save the flash! this has saved me!!!
will this be able to restore ur flash0 cause i accidentally deleted a few of my programs
No there's nothing for that.
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 ;)
Yes. It does. I tried it :)
Now on 3.52m33-4
Thanks CaptainMorgan for the file ;)
No problem, yeah this will work on all 3.71 custom firmwares.
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
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!
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..
hi captain how are you..any new psp firmware like 3.71m33-4 or 3.80 etc:thumbup::thumbup:..:thumbup:;)
any downgrader for 3.71m33-2 to 1.5....:rolleyes:
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.
I'm having a problem, I run the program but it says it can't find UPDATE.PBP?
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.
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.
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
;):D:rolleyes::rofl: HI CAPTAIN WISH YOU AND ALL A VERY VERY HAPPY NEW YEAR...THANK,S FOR YOUR SUPPORT...:thumbup::thumbup::thumbup:
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.
Yes the UPDATE.pbp is corrupted just download a normal 1.50 update pbp and rename it and you will be good
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.
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!!!
:/ it keeps saying that the download session is invalid and wont work :(. Can someone help?
do you have an alternate link? rapidshare seems to have something against me or sumthin.
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.
Thanks so much! Im so glad to be able to play my psp again:thumbup:
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.
would this happen to work on 3.80 M33-4?
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.
how do i load it in recovery?
iam in recovery but cannot find it i put it on psp/game/update
ill try as soon as i can
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.
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 ;)
i found out i had to rename the folder UPDATE to RECOVER than it loaded and said doing preperation then it froze -.-
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.
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 ;)
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?
