(big?) mistake: 3.02 OE-A and then 3.03 OE-B

Hi there,

I made a (big?) mistake... i downloaded the 3.02 OE-A installer and directly after the 3.03 OE-B uptade which seems to be a bad thing: every game/program i launch makes my PSP to shut down...
I can still watch videos/photos or listen mp3...
Can someone tells me what to do or to redirect me to some tutorials?
Is it bricked?

Thanks a lot, i'm kinda scared...

PS: i tried to downgrade ("r" button then selecting eboot) but it ends the same way: my psp shuts down...

Weird, Ive never heard it doing this, but if its 1.50 games go into recovery mode from startup and hold R while
you turn it on. You need to switch to 1.50 kernal before playing 1.50 homebrew.

Thank you for you reply.
I tried to change the kernel but it stills doesn't work.
It's seems that i made a big mistake, i can't no more launch UMD or memory stick games/apps... (except videos, photos, mp3...)
As I said, I also tried to delete the 3.03 OE-B from the "r" menu but it has shut down my psp...

I'm now thinking in a way to come back the way it was... but i don't have much knowledge in firmwares... Maybe if i install the previous updates it could work......

Anyway thanks for all the help.

to run the eboot thing at recovery u have to put those files onto ur psp exactly like it says first PSP then to the GAME file then there u copy the RECOVERY from the 2.71 se-c update( u have to download this then u extract the files and ull see flasher for recovery go in there ull see RECOVERY copy that to ur psp game) then u have to download the 1.50 eboot and after download rename to UPDATE.PBP and but that in the RECOVERY menu then try to run it to go back to 1.50

lol this happend to me http://www.pspbrew.com/forum/viewtopic.php?t=6937

Well kinda good, it means that my psp isn't bricked (it seems...)
From now on, i'll be very careful to fix it and follow your instructions.

I have to copy the EBOOT.pbp in the PSP/GAME/RECOVERY/ folder like it's asked.
Then i copy the RECOVERY folder in the GAME folder from the 2.71 se-c update (that i have to download)
I will have then to download an 1.50 eboot and rename it UPDATE.PBP and put it in the RECOVERY folder.
Then "r" button.

Thanks a LOT for all your help, and excuse my english

lol no problem ( At least i think ur talking to me) lol

It works now!
Thank you everyone ^^
I'll be careful now
