No matter what I select in web GUI as upgrade, they always only end up with:
UC Software Version 22.214.171.12427
Updater Version 126.96.36.1994
Initially will upgrade to
UC Software Version 188.8.131.5256
Updater Version 184.108.40.20638
but reboot again to "upgrade" (in fact downgrade) to 220.127.116.1127
Tried with quite few, each time it is the exactly same
Hello @spgsitsupport ,
Have you tried Clear Upgrade Server?
There is a very common issue when the phone has been upgraded in the past via the web GUI. Otherwise you might need to open a support ticket to provide a backup and logs.
