CHARGE YOUR DEVICES

If your android device, or PC, powers off due to lack of battery while the process is underway, it could damage the device. So, make sure both of them are adequately charged and that no power interruption takes place when the process is undergoing — at least 50% battery of the device and laptop is what we would recommend.

OTHER THINGS TO TAKE CARE OF:

└ Use original USB cable to connect your phone to PC.

└ Do not use the procedures given below on Mac (using VMWare) as it works best on proper Windows PC only.
