Install TWRP Recovery and Root Samsung Galaxy Tab S3

It hasn’t been a week since the release of the Samsung’s new Galaxy Tab S3 and the developers at XDA have an unofficial TWRP for it. Yes, it is still in the testing phase and there are some kinks to be fixed. But isn’t it obvious for such an early release? However, if you are eager to flash stuff or root your tablet then rest assured as this TWRP gets the job done.

A huge thumbs up to ashyx and suzook of XDA. They have put a lot of hard work in developing this. I have also left a link to the original post down at the end in case you want to check out the original thread or support the devs.

Steps to Flash TWRP Recovery on Tab S3

  1. Power off your tablet (To do so hold the Power button for a few seconds and select power off).
  2. Now, press and hold Power + Volume Down + Home.
  3. A warning message will be displayed, press Volume Up to enter into Download mode.
  4. Next, open Odin on your PC.
  5. Under the Options tab uncheck Auto Reboot.
  6. Now, click on the AP button and load the respective TWRP file.
  7. Next, click on Start.
  8. After flashing the recovery immediately boot into recovery (To do so hold Power + Home + Volume Down).
  9. When the screen goes blank quickly release the Volume Down button and hold the Volume Up button (Make sure not to release Power + Home while doing this).

That’s it! The device should now enter TWRP recovery.

The Tab S3 enforces dm-verity. Any modifications or even mounting the system will put the device into bootloop. To prevent this TWRP recovery will ask whether you want to keep system as ‘Read only’ or ‘Allow modifications to the system’. However, If you select Read only then the device will flash TWRP recovery at every boot. If you select the latter than you need to flash boot image patcher in order to disable dm-verity.
