Fixing terminals
I had one with a tamper error which is pretty ease. Just need to desolder the old internal battery, solder in a new one and run the software. However someone had done a half assed job and only soldered it halfway though, then soldered the rest with a huge solder ball. I got off what solder I could and tried to get the battery in but couldn't. I heated it in the preheat station for 30 minutes like I normally do on stuck ones. Unfortunately I forgot that I was testing with it on Friday and left it set to 400 C. When I pull it off the preheat station, 2 IC's and a connector fell off. Somehow I even managed to melt the pads off the connector. I don't have the stuff to fix pads right now, so I had to pitch it.
Killed a $250 machine because my dumb ass didn't look at what temp the IR station was set to.
