power button stuck on "on"
Since yesterday my SGS is having a very strange issue: It seems that the power button is stuck on pressed state. When the phone was on I had the power menu appear and the phone shut down. Then it started again, only to turn off shortly after the second screen during boot, then looping in that state.
When I remove battery and put it back it automatically starts and then bootloops.
I can't get into recovery as it turns off before recovery can start. I can get into download mode but only for 3-4 seconds till the phone turns off again.
I removed the backplate and can't see any visible damage to the power button. Between the power buttons pins on the board there's a voltage of 7mv with battery removed, in case that means something to anyone.
So 2 questions arise:
- Any ideas on how to fix this? (apart from ripping of the power button which I'm not even sure would help)
- Any ideas how to get into a mode where I can backup my data or at least flash a stock rom? (Currently on CM9 with devil kernel and the devil logo shows for a second in the bootloop, not sure how the techs would like that if I was to sent it in for repair)
