PSP fail?

Okay, I've been on top of the psp hacking scene since 3.51 m33. Not too long, but long enough to know what needs to be known. In such, I've gained some good reputation amongst my peers as being the first to introduce homebrew on the psp in my school, along with at my job. Thing is, even though they now start using homebrew on their psp, none of them are on top of the news, or even bother to see the new upgrades. Its pretty sad really. And, of course still, when problems arise they rely on me to help solve their problems. Thus we have this new one. Apparently the psp would not read the UMD disks. Now, I ask myself, why would you need a UMD when you have a hacked PSP and play games off of the memory card? No answer. Anyway while trying to solve this I began playing around with the UMD case, poking inside of it and moving some of the things inside of it around. Sure enough, the UMD disks started to get read. Whoopdeedoo! I was finished with what I needed to do, or so I thought. The UMD drive was not the only problem. As of right now I am taking the psp apart to try and find out why the start/select buttons are not working. Neither are the triangle,x,circle,square buttons (at least in game, on the xmb they work fine). So now I have to fix this issue. On the last psp that I fixed, the wifi switch was lose and would not switch on. These problems now-a-days are more geared towards hardware issues. I am NOT a hardware modder. I am a software modder, based on homebrew. NOT HARDWARE. Why don't these people get it straight?
