In this guide, we will show you the steps to root your Samsung Galaxy Tab S7/S7 Plus via Magisk patched boot.img.lz4. When it comes to the tablet domain, then there’s no denying the fact the offering from the South Korean conglomerate is churning out the absolute bests. In this regard, one doesn’t have to look any further than their seventh iteration. The Snapdragon 865 5G+ as the underlying chipset, Adreno 650 GPU, up to  512GB storage, and 8GB RAM are just some of its noteworthy features. Likewise, it is quite an active player in custom development.

Be it for flashing custom ROMs, recoveries, or trying out a plethora of mods and tweaks, there’s a lot to look forward to. However, as far as gaining administrative privileges is concerned, the process is a tad different with this tablet. Rather than directly patching the AP file via Magisk and then flashing it via Odin, you will first have to extract AP, get the resultant boot.img.lz4, convert it to TAR, patch it via Magisk, and finally, flash it via Odin. so without any further ado, let’s check out the steps to root your Samsung Galaxy Tab S7/S7 Plus via Magisk.

  • Hi,
    Will this flashing process wipe all of my data? I have already unlocked bootloader, so I already wiped once and wouldn’t like to do that again…

  • Way too much work and a lot of risk with very little benefit now with rooting. What happened to non destructive rooting?

    Anyways, the lack of comments make me apprehensive and skeptical.

    • Sadique Hassan

      Yes, as opposed to early times, rooting has now been confined only to a very small audience of tech enthusiasts because OEMs [especially Samsung] themselves provides so many features that in most cases you don’t even need to root. Plus the risk attached with rooting further compels users not to try it out. As far as lack of comments goes, I can’t comment on that, but yeah, you could count on the part that the instructions are right on point.
