I don't know really, I think it did.
So. Two days ago I read that WipEout Pulse was released in Euroland. I decided to pick it up and once I got home I put the game in my PSP. It required a firmware update, 3.71 to be exactly. I didn't want to go the legal route (i love me some Mega Drive Sonic) so I searched the internet for the latest Custom Firmwares. Apparently Dark_AleX and his team already released a 3.71 M33-4 or something like that. I installed it and everything worked fine. I played some Pulse listening to my own custom soundtrack and then I thought about Beats (the rythm game which is for sale in the PSP store). That's where it went wrong.
It's 8 euro (which is NOT the equivalent of 5USD) on the European PS Store, so I wanted to see what the hype was all about by checking the trailer first (also available in the store). It required to connect my PSP to the PC. I did that and it told me that I had insufficient memory storage, while I had like 462mb of free space. I rebooted my PSP, reconnected it and again ''Insufficient Memory''. So I browsed my PSP and saw that all of the directories were gone (PSP, Music, Photo, etc) instead of the usual directories there were three I had never seen before. One of them was called ''vsh'', I think I saw this mentioned when looking up for info about custom firmwares. So I knew everything wasn't alright. I decided to give up all of my savegames and format my Memory Stick, I did it through my PSP, PC and PS3. So that's three times of formatting for one memory stick. And the three directories were still showing up!! I decided to remove them manually (right click -> remove). That did work. And then my PSP turned into shit. It wouldn't turn anymore since that very moment. All I'm getting now is a black screen and the green power LED. Nothing else.
Does anyone know what I did wrong? Did the PlayStation Store somehow detect that my PSP was running Custom Firmware and decided to fuck it up? Does anyone else have had a similar situation? What should I do next, is Pandora's battery a safe option (I'm able to borrow a friend's PSP, but I'm afraid to brick another one)?
Any help is welcome.
Sorry for my broken English btw.
