The methods involved in flashing custom recoveries, roms and rooting your phone are highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is SAMSUNG in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. In case of any mishap we may not be held responsible. Follow these instructions to the letter to avoid any mishap or bricking. Make sure that whatever you do, you are doing it at your own responsibility.

Pre-installation Checks:

This will only work on I9082/I9082L. So, if you don’t have afore mentioned models please don’t try.
Ofcourse battery should be charged to at least 60%. (We recommend 80% though).
