I think I have a brick. My recovery in 3.40 OE-A didn't work well, I couldn't come into the configuration menu. So I went back to 1.5. After that, I wanted to get my 3.03 OE-C back. It all went well. After it was finished I pressed the x button and my psp went off as usualy. But when I turned it on, I get a blank screen. The green power light stays on for like 20 seconds. Is the story over or is there something I can do? My guarantee seal is a bit broken because I once turned on an other faceplate, so I think returning it to Sony isn't a possibility..
Edit: My recovery menu doesn't work either...
