I have a Padfone 2 wwe running stock firmware and locked boot. Yesterday the phone just stopped charging and wont turn on normally.
When turning the phone on it shows the empty battery icon and then immediatly reboots. This leads to an infinite loop. I've had it going through this loop for hours, no help.
When put the phone in the dock nothing happens. If I try to turn on the phone while in the dock the white spinning circles, usually shown when docking the phone, is shown for a few seconds then it turns off again.
When unplugged from power source I cant access neither recovery mode(power+vol down) or CSC/fastboot mode (power+vol up).
When plugged in to power source I get into CSC/fastboot mode. If I connect the phone to a computer I get a ASUS Fastboot loader devide. However ADB don't find the device when I use the ADB devices command. (Tried following the Tutorial: Un-Bricking Padfone 2 (and possibly other android devices): http://forum.xda-developers.com/show...2256977&page=4 guide)
When plugged in to power source I get to the first menu in recover mode (Recovery/Restart). However if I select Recovery the phone dies and the reboots again.
I've tried unplugging the battery for 30 seconds and then plugging it back in again, no help.
So my question is if you think a new battery will solve it or if I should try something else?
I sincerely believe logic board is gone.... But worth a try disconnect the battery, connect a power supply (not the charger as it is not so strong) and then power on. If phone starts, OK, problem was the battery, if not it is the board. As usual, do it at your hown risk....
