I updated my 2.71 TA-082 PSP to 3.03OE-B and I'm having some problems with some ISO loadings.. Looks like I didnt made a 100% flash..

I would like o start it again downgradind to 1.5 firmware.. How to make that with the 3.03OE-B ?

I already have the official 1.5 firmware eboot but that is not loading from recovery menu alone... Is there any other file i have do place in there?

Thanks you guys

are you using no umd mode, if so then dont!!!

to get back to 1.5
put the 1.5 eboot renamed as UPDATE.PBP on your recovery folder and choose the "RUN PROG AT" option in recovery mode

What's wrong with your 3.03OE-B at the moment ?

If you really want to go back to 1.5 and start again then download this :- http://rapidshare.com/files/9851545/3.02.rar

Extract the 302_BASIC_Installer.exe and run it. When given the option select to install '1.5 Recovery'.
Once installed. Switch off your PSP. Switch back on holding R and run the Recovery option.

the problem is that some games like tekken ressurrection, mortal kombat unchained, killzone are not working properly, so i think i made a bad flash...

ps: i crashed my psp hard yesterday while rollerblading.. its dead now.. fckd the whole screen and maybe the lens... only 2 weeks of use :(
