I tried flashing TWRP on Android 11 today with the image provided (Odin 3.14.4).
I used AP slot with .img and tried packaging it to .tar but both won't work either way (first just stops at checking file and the ladder closes the odin).
My tablet is already rootet with Magisk.
I'm on firmware BUC1. Is that an issue?
Nevermind, got a "converter".
What are the buttons to push to get into recovery mode?
Already tried Ian TWRP + my kernel on T875.
It is kinda working but has a corrupted display issue.
Everything covered with blue overlay except the twrp title(cpu usage&time%battery).
So maybe u can use the recovery in a shell mode.
Another trouble that I could not boot into a system before reflashing stock recovery.
Welcome to TWRP for the Samsung Galaxy Tab S7+ 5G (T976B). This same image will also work for the wi-fi-only T970.
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.
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.
First release with Android 11 kernel, built for BUA8 firmware.
Any file beginning with Magisk- is now considered flashable.
Fix device rebooting only to recovery.
Fix spurious attempt to perform digest authentication when flashing .apk file.
Report the device as running Android 11.
TWRP will now include files named Magisk.apk, app-release.apk or app-debug.apk in the list of flashable .zip files. This is to accommodate the new packaging of Magisk as a payload within the manager app.
Merge post-3.5.0 release bug fixes.
Update to TWRP 3.5.0.
Fixed bug that causes unmounting of System when Advanced menu is entered.
