Starting Another Upgrade Attempt after 5 Retries
When the Upgrade to OS 11 even if a previous upgrade attempt failed option is set and the upgrade has failed each time, the system will stop trying after 5 attempts.
To reset the retry counter:
In the Setup or the UMS profile, go to System > Update > OS 11 Upgrade and deactivate Upgrade to OS 11 even if a previous upgrade attempt failed.
When the setting is effective on the devices, go to System > Update > OS 11 Upgrade again and activate Upgrade to OS 11 even if a previous upgrade attempt failed..
The retry counter is reset, and the devices will try upgrading another 5 times, if necessary.
