my K4NT keep rebooting every 3 minutues even I turn off the WIFI, nothing can change that, I tried hold power button for 20 seconds, reset to factory default... I can't even read book now even I give up the WIFI connection.
is there anyway that I can restore the system image(firmware)? or downgrade to V4.0.0? or any solution suggestions?
Much Appreciated.
