It still vibrates when I put in the Anker battery though.I think what I'll do today is test the voltage on the battery before putting it into the phone to make sure its not dead. Unfortunately, I could not find the stock battery that came with the phone.
I know the button has no cable attached, I meant for you to unplug and reseat all ribbon cables that are there. I think there are 3 or 4....maybe 5. There are disassembly vids you can reference though. As for the power button, it has been known to go bad. We've had it reported quite a few times around here in the past several months. Sometimes just jiggling it, or messing with it a little seems to help, otherwise itd have to be replaced. If you put the battery in, and the phone tries to power on without you pressing power, this is most likely the problem. From what you have said though, I doubt this is your issue. It could simply be memory going bad as well. I have seen a few reports of this. Unfortunately, short of replacing the motherboard, there is no fix for this.
Im, not saying that is the problem btw. Just a possibility.
