My Quest tablet is accidentally locked yesterday it asking for gmail and password but i forgot the gmail id and password.So after a long search i found lots of things such as unlocking tablet pattern lock,gmail lock,pin lock etc.These topics only be successfull only when the tablet is in recovery mode.So i tried to put my tablet into recovery mode by pressing vol + and power button.But there appears a android bot lying with red traiangle exlamation.So i simply tried to access recovery menu by pressing power and the vol + .But nothing happens neither than a dead android bot lying down with a red traiangle.


  • Same issue (different viewpoint): can't use adb shell in recovery mode. According to the comments there, ideas from Cannot unlock tablet as have no internet connection? have already been tried without success. fastboot -w seems to be no option as OP wasn't able to enter fastboot mode either. adb shell seems to have trouble finding /system/bin/sh in recovery.
