Answer to "The Tab is in an endless reboot loop."I answered this previously saying to try using the OEM charger, but mine just started doing it again, but I don't have the OEM charger anymore. No other charger worked, but I fixed the issue doing this: 1. Pull back cover off with spudger. http://www.techrepublic.com/blog/crackin...-open/galaxy-tab-2-70-teardown-reveals-efficient-hardware-layout-and-replaceable-battery/ 2. Unplug battery. It's the connector one with red and black wires. 3. Press the power button, and hold for 10 seconds. Use your spudger or fingernail. 4. Plug battery back in. 5. Plug charger cable back in. You should see it charging again. 6. If not, repeat steps 2-5. Otherwise, snap the back cover back on!
Answer to "The Tab is in an endless reboot loop."I had this exact same problem. No advice about thumping the back, nor would it boot to the recovery screen by holding buttons down and all that (3 different variations attempted). I tried disconnecting the battery and still nothing. Mine kept appearing like it was trying to charge, but then kept rebooting, even while plugged into a charger, left overnight and all next day. What worked was using the OEM charger. I was using an aftermarket charger, but this isn't powerful enough to get the required "umph" when the battery was completely dead. The charger I was using worked fine while the battery had some charge on it, which is why I didn't think this would've caused the problem, but made sense afterwards. Good luck.
