I get a psp slim 2004 ta-085 and I encounter some problems, I need your help.
When I turn on the psp, the xmb don't appear, I can only see the waves.
The only ways to display the xmb are that :
-Run the recovery and lauch run program at /PSP/GAME/RECOVERY/EBOOT.PBP
-Remove battery and memory stick and wait a few seconds
But even when the xmb appears, i can't launch umd, and homebrews work half the time.
I've try to reinstall many times the firmawre , format lflash, repair idstorage, but nothing works.
A technician said that i need to copy idstorage keys from a healthy psp ta-85 and put them on my psp.
So i'm searching someone who can help me and has a psp slim with a ta-085 motheboard.
