Hi guys
I wanted to install TWRP on my sm-t295. I got to the point where after Odin I went to step 8. When the phone rebooted I got the yellow exclamation mark and the text I am not running official samsung software.
Then I got a red text at the top that security check failed on boot.img
at the bottom it ways: security error, this phone has been flashed with unauthorised software....
After the first time I saw the security error screen, I dont see it any more, only the first yellow exclaimation mark screen.
I can not get to TWRP
Otherwise the tablet boots in android. It is android 11. Firmware T295XXU4CUF7
What did I do wrong
