My G1 has survived a lot of abuse at my hands. Many wipes, hacks, failed mod attempts…
However, what ultimately led to its demise was a simple hardware failure; also possibly my fault.
It seems as if the Red Power button was stuck down. So no matter what I was doing the Power Off menu kept popping to the foreground. As soon as I would dismiss it, pop! It would be back again. Which made it impossible to anything with the phone.
