I have a 1.6 with the SmartXX V2. I had to do that ridiculous LPC rebuild and every once in a while, the modchip wouldn't start up, resulting in a FRAG. I'd tap the bottom of the XBOX a couple times and eventually it would come back on and stay on.
It seemed to be pretty random. It'd cut out RARELY if it was already on. Most of the time it would just not turn on on boot up.
Recently however, it looks like it has gotten worse. I was playing a game and it froze. Sure enough, modchip lights were off. I tapped the bottom of the XBOX, which resulted in the lights flickering on for just a blink of an eye. I can't seem to get it to stay on!
I completely resoldered the LPC rebuild with fresh wires and I still have the same issue. The only thing I can think of is the D0 point is flimsy (although I've resoldered that), or the solder holding the modchip on (quicksolder method) is flimsy.
Anything else I could look for? <
