3.40 OE-A Firmware Install Error

Alright, so im trying to put my friends psp (originally 2.60) To update to 3.40 OE. I have done it with mine and my other friend but his seems different. First of all it is not a T-A082 or whatever it's called. 2nd, i succeded in bringing it to 1.50 but every time i run the Firmware install it had the "The game could not be started (80010002)". 3d, i have done the updater to get the DXAR file and i have moved it to the 340Flasher folder and the DXAR file is not a 0 space file. However in his game memory two icons are invisible which are the corrupted datas, and im pretty sure me and my friends psp's corrupted data was not invisible. Any help appreciated, Thanks.

I think you should go to recovery mode and then switch your kernel.

He hasn't installed it yet.

Just take the data.dxar, move it to 340flasher, move the 340flasher and 340flasher% folders to /PSP/GAME. It shouldn't mess up.

They were and and are already in there though

did you ever tried to use YOUR memory stick that contained the ALREADY MADE folders with the DXAR???

ill try that, but i thought if i used my folders with the dxar already made it might brick my friends

who told you that??? lol
i did it lots of times, trust me

ok say i hypothetically 'deleted' the files lol, would it work if i just reinstall it on mine?

yeah, make sure you have everything ready

Got it working by switching memory cards with mine, it worked like a charm! Thanks.
