    Hello everyone!

    I decided to do some experimenting with my PSP Testing Tool :p

    On the motherboard there's 3 individual DIPSWs labeled (Normal <-> Flash Write), if you switch them to Flash Write, the PSP screen goes blank but the power remains on and seems to be looking for something.

    I tried to hook the USB up and see if its showing up as anything, I'll keep experimenting with it and see if I can figure out what's going on.

    On a random note, there's another set of DIPSWs labeled 1/2/3/4 and across from those numbers 0/L/8 (or B?) /N.

    If you switch the 2nd switch from left to right (away from the number), it powers on the unit but doesn't actually turn it on. So the fan kicks on, and the motherboard lights up.

    I tried to see if there was any sort of service mode capabilities by turning all 3 flash switches to write, and then turn on the auto-power switch with a Pandora Stick in it but nothing happens yet...

    I'll keep updating the thread/my post if I find anything cool :D

    Service mode is actually triggered though a specific DPI configuration (on the front panel switches) along with a press of the F1 or F2 button. I don't know the exact combo however, I would have to look at the battery emulator firmware to find out (or try all the 255 possible DPI combinations), but my H8 assembly skills are somewhat lacking.
