i downgraded mine without any problems at all.
yesterday i downgraded my friends psp. and we tried to have a WLAN multiplayer game of QUAKE on our PSPs. but for some reason his game crashes when he tries to activate the WLAN and it fails the connecton test, the green light wont even come on. the thing is we dont know if this problem has occured in the downgrading process or not. we played GTA multiplayer a few times before we downgraded. So i dont know what is wrong. Has anyone else had a similar problem? it seems the PSP recognises that the WLAN switch is on, it attempts to connect, just nothing happens.

try upgrading to 2.0 then downgrading that might fix the problem

[Physicist]

we did that. but then couldnt find a downgrader for 2.0 to 1.5, well i found one eventually. it was a bit more complicated than the easy downgrader. and it actually said that the downgrade failed, but it still works as 1.5.
his WLAN still wont come on.

[Method Man]

to downdate i need this:
DOWNDATER\DUMP\ (containing the 1.50 dump)
DOWNDATER\PRX\ (containing the 1.50 UPDATE .PRX files)
DOWNDATER\inputfl.bin
DOWNDATER\outputfl.bin
right? where i can get it from?
can u send it to my email adress:

Hi, I just wanted to make sure this is a plausable way to downgrade. A friend bought a used PSP with no numbers on the motherboard (no IC) and it had a version 2.00. So I wanted to upgrade his psp to version 2.6 or 2.5, then use this downgrade to get 1.5. Should work, right?

[Video_freak]

yes. it should.
