I have a chinaChinese tablet named Quest. I have accidentally repeated the pattern lock more than 5 times. Now I have also forgotten the email address.
So for a factory-reset reset of my tablet, I simply booted it into recovery mode. But it shows an Android bot lying with a red exclamation mark. After a spending hours, I found a shortcut i.e., volVol + and powerPower to access the recovery menu. But my tablet doesn't go to the recovery menu even when I pressed the keys.
So I simply connected my tablet to my pcPC via USB and installed drivers. In adb command prompt, I typed adb devices
. Now my tablet is listed as 20110301 recovery
. I can simply use only adb pull
, adb push
, and reboot
commands. But I cantcan't access adb shelladb shell
to unlock my tablet:. it simply says exec '/system/bin/sh' failed: No such file or directory (2)
.
What can I do?
