Which, in turn, was inspired by TopJohnWu's 'Samsung (System-as-root)' Magisk Installation Guide
It is an extended companion piece aimed at novice 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
Personally, after three and a half months of usage, I strongly advocate disabling or uninstalling unwanted applications via the Android Debugging Bridge (ADB). It's far less hassle, results in less downtime and you won't lose warranty or some Samsung-specific features by tripping Knox.
If this method seems more preferable, please visit TiTiB's 'Debloat Without Root-Info' thread for additional instructions.
