I recently pulled my old psp out of the cupboard and since I dont use it anymore decided to mod it.
It's a slim (2002 model number) and I bought it december 2007. Its the simpsons edition so its yellow.
Anywho I opened the battery and Im positive I cut the correct line. I put the battery in and the green power light comes on but nothing happens (as expected)
I then followed this guide: http://www.pspmod.com/forums/psp-har...ew-method.html
And made a MMS. I know it worked because on the DOS window it says "Write MS BOOT CODE" after the last step.

The problem: When I put the memory stick into the psp and turn it on, nothing happens. The green power light comes on but the memory stick and wifi LED's dont flash (as they are supposed to.) and the screen remains blank.
Have I done something wrong?
