I am having an issue with this psp slim and it is driving me crazy! Ok I have one working psp slim and decided to buy a second one online. After I bought it I was performing a firmware upgrade and the battery fell out of back (I didn't know that the battery case did not fully latch). Anyhow to make a long story short I bricked the darn thing! I did some research and found that to fix this I would need a pandora battery. I want to add that I knew it was bricked because when I attempted to turn it on the green light would come on but screen would just remain black. I tried to hard mod my own pandora battery but had no luck with it. Somewhere in this process my power light stopped comming on, when I put a battery in the power light would just flash real quick then nothing, even with power cord plugged in same thing. It will charge a battery but that is it. I went ahead and purchased a pandora on the internet and put it in psp and all that happens is light flashes over and over like once a second. I know I need the pandora because it is definately bricked, but now before I can fix that I need to figure out what the other issue is. I do know the pandora works because I tried it in my working psp. Does anyone know what the problem may be? I thought maybe with the battery I attempted the first time maybe blew a fuse or something????
I have a similar problem with one I purchased from craigslist. It basically came in the condition you described but i'm not sure if the battery fell out or anything like that. Anyway I'm basically just lurking to see if anyone has a solution for you problem, as I also have both a properly working mms and pandora.
Just to double check, you are holding down the correct button for it to boot the mms, right? generally the L or R trigger.
