Hey, I am kinda back again... Sorry for being a pocky and leaving you all here, love you <3

Anyway, I gave my PSP 2000 (then one with ta88v3) to a friend of mine, because I haven't used it much. So, in a couple of months (that is now) he writes me that his little brother accidentally updated to the newest firmware, I think it's 6.60?

Problem is, the PSP had 6.20 TN on it, and it was made permanent... So now, it just doesn't turn on. The green light stays on for around 20 seconds and then turns off. If he plugs the cable in the orange light stays on.

Guise. Wat do ;_;
