BEFORE WE BEGIN
- Installing a custom ROM on the Galaxy Tab S2 does void the Samsung warranty. Any device with Samsung’s Knox security will find it difficult to get that warranty back.
- Make sure you do not skip the step for taking a NANDroud backup during the guide or else your data cannot be restored. During the flashing of a new ROM on your device, we are going to wipe the current ROM and any data that is not backed up before then cannot be restored. The backup itself is very easy thanks to the NANDroid backup button from within your recovery.
- You will need a computer during the guide to transfer your ROM file over to the root of the SD card internal storage on your tablet. It doesn’t matter what operation system is running on your computer; they all will work the same for transferring your files only. However, you may wish to turn off your security features from the computer, regardless of the operating system that is running.
