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.
And since this is a little bit of manual procedure for the most part, it’s very much recommended you watch this video below first before trying it yourself, to get a fair idea of how it’s done.
The video below is of the international Galaxy S3 (yes, notyour S4!) but since the process is exactly same, that does not matter at all.
