Ok so yesterday i installed 5.50 GEN B (full) so i could play decrypted games like fifa 10 and GT, i put FIFA 10 on my psp using USB connection and played for ages. This is where the problem starts...
So this morning i tried to connect to the computer using the usb connection, but it would get stuck on "Please Wait..." i waited for 15 mins and nothing happened. So i was like maybe the USB device setting on the VSH menu was set to something else like Flash 1 or UMD Disc instead of the memory card, and i changed that to Memory Card. I tried to connect again but it still didnt work.
This is the funny bit. I went to recovery mode and stuff and tried to fix it, but it still didnt work. Then i went to VSH menu and i accidentally clicked the option MAKE PANDORA BATTERY and i turned off the PSP. After a while i turned it on, there was nothing but a black screen... xD
I think i know what the problem is, i think i need to downgrade my psp to M33 again to make the USB setting work.. But as i mentioned before USB connection gets stuck on "Please Wait..." so i got no way to downgrade my PSP...
If anyone has any information please post. Do i need a new Battery(maybe i do..) or is my memory card stuffed, not the firmware?
PLEASE HELP
