Hey guys. The other day I slipped on ice and landed on my side. I had my PSP 2000 in my pocket. I checked it out, and it seemed to be completely fine so I didn't worry about it.

The next time I went to actually play my PSP, I discovered that something had happened to the analog stick. Now, no matter what I do the analog stick goes crazy and all the fixes I've read online do nothing. I've even taken the system apart and completely replaced the analog nub assembly with another I bought on ebay to the same result.

So what I'm going to do is send it back to Sony for repair (read: replacement). Problem is, I've got custom firmware on it and am worried about potential complications such as them charging me an extra fee or flat out refusing to repair it for voiding the warranty.

So tl;dr, is there a way to remove all traces of the custom firmware and restore the PSP to it's official Sony firmware?
