Hello folks, this is my 1st full a) post and b) month without my s3 phone (been borrowing my friend's s5 active in the meanwhile). One day the phone started a boot loop, so I did some searching on this forum.
I tried the following:
1. The Old Remove & Install Battery Trick: took the battery out for a minute or so, then put it back in - the phone did not turns on by itself. I thought about ruling out a stuck power button. But I sent it in for repair anyway.
1.1 Tap the Power Switch With the Battery Trick: I did this, and didn't see any change. Still boot loop.
2. Replace Power Switch: removed the logic board, and sent it in to a service to have a new power button soldered on. The logic board was put back into the phone, but still a boot loop.
3. New Battery: purchased a new gorillagadgets battery, thinking it was a battery situation. After the battery was full charged (the screen stayed on during the entire re-charge process, FWIW), I removed the SIM and micro SD card, still get a boot loop.
4. Safe Mode: with new battery and new power switch, I tried pressing home button and volume down in order to boot into safe mode. When I do this, more times than not, I was able to use the phone in safe mode for a minute (without my SIM and memory card installed) as opposed to not in safe mode I'd get a reboot shortly after my screen unlock screen showed up, but it *usually* rebooted itself immediately in safe mode as well.
5. Recovery Mode with Cache Clearing: with new battery in, but sim and memory card removed, I successfully booted into recovery mode. I chose the option to clear the cache. And then I rebooted the phone. I still get a boot loop.
I am wondering if I should try to rule out everything *but* the logic board. I'm thinking of buying a used s3, and putting my logic board with the soldered-on new power switch. If it works, then something about the rest of my phone was broken. The assumption with this is that I can take out my logic board and just swap it into another phone. I could be wrong, and if so please correct me.
Another option I'm thinking about is to completely remove the power button, and go with a program called button savior j. I am not sure if this option would even work, because I might remove the power button and all the soldering, but then get a loop again, well before even the option of getting into google play and downloading button savior is possible.
