Hi, my PSP wont boot up when I have my 4gb sandisk mem stick inserted.
Ejecting it starts up my PSP, putting the mem stick back in once its booted to the XMB will let me read the memory stick, play games, etc.
I already reformatted, and before anyone asks, yes, I am sure it is a real memory stick.
Does any one know what the problem is? When I boot up my PSP the memory stick light just flashes for about a minute and the whole system shuts off. I can't even go into recovery. I am using 3.90 M33 Slim PSP, and this was happening before I updated on a 3.80 M33-5.
Thanks in advance
