if your bootloader chages up version from U1 to S1 , No way to downgrade from S1 Back to U1
( Android 11 for tab a7 lite used U1 then ....xxxxx)

Now don't have TWRP on Android 12 for your tab

Recuerde que esto está en desarrollo temprano (alfa)

It doesn't work:

> Adb Sideloading

> Vibración (problema menor)

> Otros problemas: a veces, cuando arrancas, el toque de recuperación no funciona y la única solución es volver a flashear TWRP nuevamente desde Odin, este es un problema del kernel, necesitamos un kernel personalizado. Descubrí que, en ese caso, puede reiniciar con USB otg y mouse conectado y twrp podría comenzar a funcionar en el próximo reinicio.

Instrucciones de instalacion

Destella TWRP de Odin en la ranura AP y mantén presionado Subir volumen + Encendido mientras parpadea hasta que apareció TWRP.

Vaya a Avanzado > Terminal y escriba "multidisabler" (sin comillas), luego borre datos.

Ahora reinicie en el sistema, después de completar la primera configuración del dispositivo, reinicie en TWRP nuevamente para ver si puede ver el contenido de su almacenamiento interno, debería, si es así, se ha deshabilitado con éxito el almacenamiento interno de Samsung.

Any chance that we can downgrade portions of the bootloader to work around this issue, much like we did on the SM-T290 by rolling back aboot.mbn and vaultkeeper.mbn?

Do not be misled! The letter U means Update, that is, update. And the letter S - Security - Security, that is, increased security. This is done by changing the encryption, so rolling back from S1 to U1 firmware is impossible Without resetting the data! and that's all ... Roll back to health even to the first firmware 11 of the android, but with a data reset, until the bootloader version is 1, that is, it has not been upgraded
