It is an extended companion piece aimed at ALL users and meant specifically for the SM-T720 (Tab S5e).
Introducing root and further tampering may potentially lead to unfavorable performance and/or shortened device lifespan.
In extreme circumstances, it may render your device OR specific hardware components unstable or non-functioning.
By following this guide, you ACKNOWLEDGE these risks and release AHE_XDA, XDA and its CONTRIBUTORS of ANY and ALL responsibility.
In many states, countries and territories, introducing root voids device warranty (manufacturer's and/or third-party). Please consult your regional Samsung office, place of purchase or third-party warranty company to determine if these terms are applicable to you.
ALTERNATIVES TO ROOT
If you are looking to maintain your warranty and access to some Samsung-specific features, consider disabling or uninstalling unwanted applications via the Android Debugging Bridge (ADB).
TiTiB, a genius in his own right, has a thread dedicated to the Tab S5e and bloat removal without the cost of warranty.
