Development [RECOVERY][UNOFFICIAL] TWRP for Galaxy Tab S8 Series (Snapdragon)

[afaneh92]

Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

 * Your warranty is now void.
* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or your getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

Note1: You need a custom permissive kernel to boot with R/W vendor.
Note2: If you got bootloop on Samsung logo, reboot to TWRP and wipe metadata from Advanced Wipe section

You have no idea how excited I got when I saw this. I'm going to try this first thing tomorrow and post my results! One question though; When you said "You need a custom permissive kernel to boot with R/W vendor.", is that the one that you've linked in the initial post?

Yes its.
Also if anyone have the regular Tab S8 send me recovery.img here or on telegram

Sure, this is for X700XXU1AVCD/X700OXM1AVCD/X700XXU1AVCD (Tab S8 Wi-Fi Middle East).
I used this to root but it may be corrupt so you might wanna check.

Hello ,
Is it possible with this twrp version to use the sd card also ? Thank you for your answer .

I see magisk v25 change log mentions
Fix vb meta extraction implementation.

So does that mean magisk v25 will disable vb meta automatically now?

I belive so. IIRC, if you've rooted your tablet by patching the AP file with Magisk and flashed it in Odin, then vbmeta should already be disabled. Magisk, and therefore root, will still persist even after a factory data reset because your device is running Magisk as a system app.

Finally awake. Gonna go ahead and flash TWRP on my Tab S8+ and share my results!

I don't know about magisk becoming a system app I own the tab s6 I'm on one UI 4.1 and have magisk v25 And it doesn't install the system app so I don't know about that. I don't own s8 tablet

Then don't spam every thread with tab s6 topics

I come baring results. I flashed TWRP and vbmeta in Odin as described in the initial post, and it booted into TWRP! However, the good news ends there. The touch screen doesn't seem to work when in TWRP, and interestingly, when I have the keyboard attachment on, the install button darkens as if I'm pressing it no matter what I do on the trackpad. I've tried rebooting the tablet by holding pow + vol- but all it does is reboot once and then put me back in TWRP. I can use ADB to go into download mode, but I can't boot back to Android. Looks like I'm gonna need to flash my patched firmware and try again when this gets fixed. For context, I flashed the gts8p TWRP tar because I have a Tab S8+, but the WIFI only variant (X800), which is in the supported versions list, so I'm not sure what went wrong.

Thanks for the feedback, will look into it soon. If you can send me vendor/firmware folder will try to fix touch.

How do I do that? Is it a command I can run in adb?

Alright, here's the vendor folder! It's compressed from the original size (~2.15GB).

Wow, I asked for firmware folder from vendor not the whole vendor.

Ohhhhhhhhhh, I'm sorry LOL. When you said vendor/firmware I assumed you said to upload the vendor folder OR the firmware folder. I'll remember that for next time. XD
