How to downgrade 3.10-A' to 3.03 OE-C?

ChaosStalker · 02-20-2007, 07:56 PM

Ok, now I'm asking this (topic) because I've search all the threads, and there's none I can find that actually REALLY talk about it.

Recently I just got a PSP and I downgraded to 1.5, then upgraded to 3.10 oe-a',(sig)... then I heard of some kind of recovery mode here and there, but it didn't grabbed my attention at all, cuz I had just upgraded. But now I'm hearing from most people that 3.03 oe-c is actually better than the newer 3.10 oe-a'. I've searched files at psp-hacks.com and I don't see anything?

So I was juste wondering if someone could give me some directives to downgrade from 3.10 A' to 3.03 C. Where can I use that "Recovery mode" ppl are talking about? Any idea?

Oh yeah! One more thing... It's the first time I got this kind of problem with my PSP. I was running pspvba, and after the game intro, it went white screen and the PSP made some ear bleeding noise, so I turn off the whole thing. When I tried to turn it back on, my PSP just continued to flash the power light. I removed the battery then put it back on, and tried again to open the PSP and No light at all, I presume my battery just got too low and I need to charge it back? I cant have bricked my PSP loading a game on pspvba?

Well tx for reading, I wait your replies!

Thank you man, simple and everything look easy to do. I'll recover to 1.50 then upgrade to 3.03 OE.C after my PSP is fully charged. (Hope it's not a brick :S)

OMG, I just tried the recovery mode, when I chose recovery/game.eboot.pbp, the screen went black... and nothing is happening. I try to hard reset my PSP and it wont turn off! WHAT CAN I DO!? :'(

EDIT: Oh wait, I removed the battery then put it back and restarted succesfuly to the menu. But is it safe to try again?

Just FYI, the board doesn't like it when a person double posts and have been known to ban people...edit your previous message.

Second, how long did you wait after the screen went blank?

Third, it is safe to try again...

Here are PSP's recover instructions:

Just go to PSP's link that I posted in #2 and scroll down to Recovery:

Instructions
*Place folder in (PSP/GAME/RECOVERY) for Going back to 1.50 from any SE or OE firmware PSP
ok now
*turn PSP off (hold power switch for at least 10 sec)
*Turn PSP back on while holding "R" (you will get a Purple or Baby Blue Screen for 3.03oe-c screen this is the recovery main menu)
*Toggle the USB connectivity.(enable it) now transfer the recovery Folder to (if you haven't already) PSP/GAME/ after copying that Disable the USB
*Select the 3rd option " Run Program at PSP/GAME/RECOVERY/EBOOT.PBP" 6. Read the agreement, and follow the instructions
Best of luck to you. and you will have 1.50 soon

I tried back again, I got a black screen again, required me to remove the battery and put it back in again to reboot...

EDIT: Ok, i'll try that again...

EDIT: Tried again, does not work... I followed the instructions correctly, it just does nothing, i get a black screen... I waited like 3 minutes by now... nothing...

make sure you have the UPDATE.PBP in the

PSP/GAME/RECOVERY/

the UPDATE.PBP is actually the firmware 1.50 Update
renamed to UPDATE.PBP

I dont think its included in the recovery download.
