I'm having a strange problem with my totally stock S3 with the latest android update. I found it dead in my pocket the other day. It was totally unresponsive to the power key.I tried about 5 different batteries to no avail. When I plug it into a car charger, it shows an empty battery with a frozen 'thinking' circle, then turns off. When I plug it into a Samsung wall charger, it does the same 'frozen thinking circle, ' then appears to charge the battery. While it's plugged in to the samsung charger, I can turn it on. It goes through the boot screens, but crashes during the Sprint splash screen. If I unplug the charger, it is completely unresponsive again. I COULD boot into recovery mode (with the samsung charger plugged in), and have tried wiping the cache. I don't want to factory recover it because the data on the phone is more important to me than the hardware. I can't get it to boot into safe mode.
Today I flashed the firmware with ODIN. ODIN says it was successful, but the phone still has exactly the same problem. If there's no way to fix it, is there any way to pull the data off?
Thanks in advance for any ideas.
