sorry bout the all caps title. alight, i was given a psp 1001 from a buddy of mines about 3 days ago, that he had broken when he first got it in 2005 after a month of having it. he broke the power switch. i replaced the power switch. it also dosent have the battery but it does have the power cord. (he said he lost the battery) so when i try playing a umd the system cuts off. is it because it doesnt have a battery? it works when i dont have a umd in the system, and im at the home screen, but as soon as i close the umd door with a umd in it, it shuts off? also, when i hit the wifi switch it shuts off to. is that because it doesnt have a battery also? and one more thing, just to show you how old this thing is, its running on 1.52 firmware. i want to run iso and homebrews on it, so what steps would i need to do to run them from this firmware? i know this is long, but any help would be greatly appreciated.
