Then its less likely to be hardware related, I would do a full format with fastboot then flash all stock firmware and software and see what happens
I have tried that with no luck. Once it boots up and I remove it from the charger, it dies and starts to bootloop.
So everything works great so long as tablet is connected to power supply? Only loops when disconnected?
If this is the case and you have done full format and return to stock then I would assume battery is at fault
But you also said that if you boot to recovery or bootloader then take it from power supply all works well, that would lead me to believe that it is software/firmware related. Are you positive you did full formatting?
Well best to double check if it loops in just os or also in bootloader and recovery, it will tell a lot
And by fully wipe/format I wouldn't count a toolkit doing this ad it often isn't what happens, if you have issues - always manually format and manually flash, otherwise you can't troubleshoot properly and we all just go in circles
It sounds like a bad battery, did you also manually format with fastboot? If not try this as well
I have tried that as well...I am thinking it is a hardware issue as previously stated....amazing...spend $500 for a piece of hardware only to have it die a little over 12 months later....talk about pissed off....
