Have you ever had anything go wrong with your psp?

Well, I was trying to custom upgrade my PSP when things didn't go well. I ended up trying to use a MSphat Mod Patch for the Memory Stick when it really didn't need to anyway which resulted into my PSP not being able to read the games from the Memory Stick. After browsing a local site that focuses on PSPs, I found out that the model of the PSP that I had did have issues and had to be Downgraded and then upgraded with a Service Battery, or what they call as 'Pandora.' After getting it restored to how it was when I first had it, I still tried to do tutorials on downgrade and upgrading it but, to no avail up to now. And then there was this time when the analog stick wasn't responding properly, I eventually screwed it out and took a look at the analog. Just aligned the sensors and it came back functioning properly again I really wish that I could downgrade and upgrade it myself so that I wouldn't have to look for help..
