Factory Reset MTAB701 or Telechips 8xxx

December 19, 2012

I have been searching the internet for many months now to try and factory reset my Mercury MTAB 701.

The option available in Privacy-> Factory Data Reset Doesn’t work at all in this device.

Like many cheap android devices in the market, this device is a re-branded Chinese made Telechips 8xxx model.

The trouble I faced is two fold.

1. Reset the device

2. Backup and Upgrade the Stock ROM

To reset the device you need to do the following.

while starting the device

Hold down the Power-Key (Last button in the Right Side panel) and the Menu Key (Middle-Left on the Front Panel).

Holding these keys immediately after you see the device beginning to start will sometimes result in a blank screen being displayed, a few seconds later you will see the android logo and the device just waits. Now you need to press the power button once, then the volume up down keys a couple of times, this will show you the menu which allows you to update the Stock ROM or Factory Reset the device.

Device Spec can be found here
