I own a Galaxy tab a 10.1 with s pen (2016). I flashed via odin, twrp 22.214.171.124 and the system booted fine. Then I flashed the last version of SuperSU and since then the system doesn't turn on and I get the famous
Verification failed. Unable to restart your device. The integrity verification has failed. You need to restart your device to factory default settings. This will erase your data.
As I can't access my data in twrp, I tried to flash no-verity-opt-encrypt (6.0) but it doesn't help and I still can't access my data on the internal storage from twrp. Before I do a factory reset, I'd like to backup my data. Do you know if it's possible or how can I fix this error?
Will flashing the stock firmware help?
