recovery mode is broken when flashing twrp (SM T-590) 2018 Tab A 10.5

[seeiu]

I have the verification failed issue after flashing twrp. Unfortunately, the recovery mode is also broken(the left photo). Is there any way to fix it? My device is Samsung Galaxy Tab A 2018 10.5.

You will have to disable encryption and dm-verity in order to use custom recoveries or ROMs.

Once you are in TWRP:

Wipe -> Format Data -> type yes and confirm
Reboot -> Recovery
Then download Disable_Dm-Verity_ForceEncrypt_08.18.2019.zip and flash it at the Install menu: https://mega.nz/file/eUpj3AAR#B-3_dgBX9nEj4PJufCnCl7FsiS5bJXy-XvNsBg2KQXg
