  12. Edward Basilio Jr. says:

    Is there a cwm for this just in case bootloop happen.!?

  13. Thanks for this helpful tutorial, it really works my Acer B1-A71 is finally rooted. if you encountered boot loop or it stocks from recovery mode, download this stock firmware from this site and copy it to your microsd “do not extract” and then simply power off your tablet and then press simultaneously (power button+volume up button) boot selection mode appear then select SD image update mode, “use volume up or down to choose the power button to select” then you will come in recovery mode then select “apply update from sd card” and select the firmware you downloaded then the process until its finish.
