Looks like the issue with starting firmware version. When I use the firmware version 2-1-2 and upgraded with any installer (tried with 154 and 157), it is taking around 15 mins to complete the upgrade. I also tried with 2-2-9 as starting firmware version and upgraded using 154 installer and it completed in 4 mins. Attached the ADC_FUA log for details
Tested with the build 905 with Windows 10.
Length of time required to update is dependent on the starting firmware version. The older the version the greater the potential that more needs to be updated. That is why older versions can take longer to update. You should compare times from the same starting firmware version
