Trying to roll back s21 ultra to android 11

[rogersdave77]

"Software update in progress" has been stuck at 100% for 3.5 hours...it says please do not disconnect cable....no option to cancel.

What damage will it do if I disconnect as I need to go to work and need phone?

Really didn't expect it to take this long 😕

It didn't take that long for me. Not sure why it took 3.5 hours. Have you contacted Samsung

Worst case you can use Odin to flash a previous software version (plenty of tutorial online)

Or use smart switch via a PC once you've withdrawed from the beta

Can I go back to 11 ?

@rogersdave77,

Indeed it took so much time 😔. Did you finally manage to finish the rollback to Android 11?
