TWRP for the Samsung Galaxy Tab S7+ 5G (T976B)

[ianmacd]

Introduction

Welcome to TWRP for the Samsung Galaxy Tab S7+ 5G (T976B). This same image will also work for the wi-fi-only T970.

Installation

Only proceed if you are comfortable with low-level device management and are capable of recovering an unbootable device, should an unforeseen mishap occur.

Unlock your device's bootloader and then install the recovery image below. If you use Odin to flash it, remember to rename the image recovery.img and tar it before flashing. You will also need to flash a neutralised vbmeta.img image if you have not already disarmed verified boot.

Post-installation

The Tab S7+ 5G utilises proprietary file-based encryption (FBE) in its factory state for the user data partition. TWRP cannot decrypt this, however, so it must be removed. Otherwise, you will not be able to perform back-ups and restores.

To remove encryption from your device, please use TWRP to flash the Samsung multi-disabler and then format /data again. You must use at least v2.5 of the multi-disabler.

These builds are stable and known to perform well on many users' devices.

FYI it does work on T970 but ADB is not working.. I was able to put the multi disabler and magisk zip onto my extsd card then flashed twrp, flashed multi disabler, formatted data, reboot recovery flash magisk then boot system. Keep in mind I already had my vbmeta disabled.

I then made a full backup in twrp which went just fine.

So T970 will work but adb isnt working so would need to have your files on a extsd .

EDIT: I spoke too soon.. it actually works including adb after disabling mtp.. i had something screwy with my messin with it lol.. multi disabler worked also

Got it flashed to my Tab S7+ (T970), but I don't see system as a flashable partition when trying to flash an img. Only see Boot, Recovery, Optics image, Prism image and super. I am looking to flash a a GSI

EDIT: It seems the S7+ has dynamic partitions where system.img is within super.img (which also contains other partition images). Flashing a system.img to the super partition won't do. Guess I'll have to research and wait for devs so i can figure out how to flash a GSI on this thing

repack gsi into the super.img then flash super

Can we update to this build without flashing through odin via a PC?

Also please provide a payment method so we can send money your way:good:

Edit: Just updated to the latest new build using the official twrp app works perfectly on T970.

thanks.

I have a new SM-T970 with now an unlocked bootloader. Is it save to flash this TWRP in "EUX_T970XXU1ATI2" (this is the current firmware on the tablet and no updates to "ATI3" are offered to me currently)?

One additional question: Where I can find a "neutralised vbmeta.img" for the SM-T970?

Edit2: Got it!
For everyone who is struggeling with the "neutralised vbmeta.img" as me here is the manual on how vbmeta can be "neutralised": https://forum.xda-developers.com/galaxy-s20/how-to/howto-root-s20-series-upgrade-firmware-t4079353

Stage 3: Disable Android Verified Boot
1. Reboot to DOWNLOAD mode. If you are already in the download mode, skip to step 2.
2. Download Odin 3.14.4 or newer and make sure Samsung USB drivers are installed.
3. Open Odin and put the vbmeta_disabled.tar into USERDATA slot and click "Start"
4. Your device will reboot but it will not boot into system as vbmeta signature has changed.
5. Your device will reboot into RECOVERY mode automatically and prompt "You have to reset your device to factory settings". Use "Volume Up" or "Volume Down" button to move and "Power/Bixby" button to select. Confirm and reset the device to factory settings.
6. This is the last time the data on the device has to be cleared. Afterwards, if you don't re-lock bootloader or re-enable the Android Verified Boot, you will not lose your data. Be aware, a stock firmware package contains a Android Verified Boot Metadata Image (vbmeta.img) with verifications enabled. You will need to flash the vbmeta_disable image (put into USERDATA slot) along with the stock firmware (use BL, AP, CP, CSC slots) to make sure AVB is not re-enabled and the data is preserved.

The file which must be flashed as "USERDATA" will be this (on bottom at the first post): vbmeta_disabled.tar


Now lets have a look if the TWRP is working on my ATI2-Firmware.


EDIT3:
Now I got everything to work:
- unlocked bootloader
- root with magisk
- "disabled vbmeta"
- flashed TWRP
- flashed "multidisabler-samsung-2.6.zip" and disabled with this the encryption
- Setup a last time and now I have TWRP and root via Magisk

Thanks everyone who helped to make the tab s7+ much more usable as it is out of the box.
Later I will try backup/restore in TWRP.

EDIT4:
So I just made a backup, wiped data and afterwards restored the backup: Success! The tablet is exact at the state where I backed it up.

So for others: I got a lot of information from this thread which are useful for the Tab S7+ also: https://forum.xda-developers.com/galaxy-s20/how-to/howto-root-s20-series-upgrade-firmware-t4079353

Can we update to this build without flashing through odin via a PC?

Yes. If TWRP is already installed, just choose Install from the main menu, tap Image, select the new TWRP image file and flash it to Recovery. Reboot to recovery and you'll be in the new version.

Alternatively, any Android root app capable of flashing the recovery partition can be used. Or even just dd on the command line, using a terminal program or adb to spawn a shell.

Also please provide a payment method so we can send money your way:good:

I don't accept donations, but I appreciate the sentiment. Thank you.
