Updating from an older firmware shows a fingerprint

[STew790]

I just tried to update a device with FW 1.6.0 (BL 1.3.2) to the latest FW (1.10.2) on staging Suite (21.9.1 b52f0002ea6364ac8d8a9f733709732bef4c2305) and the Suite forces me to update because of old FW (which is fine) but after connecting the device in BL mode and confirming the update, the device shows me the fingerprint to compare it with Suite but Suite doesn't respond/show this at all, it just gets stuck at 92% (as shown in the screenshot).

Expected result:

Suite shows the fingerprint so that it can be checked against the one on the device

Actual result

Suite just gets stuck on 92% of the FW update and doesn't show anything that corresponds to what is shown on the device.

Probably fixed, @STew790 will double-check.

QA NOK Unfortunately, it is not fixed. I just tried this again on staging today and I was able to reproduce it. I tried to update from 1.5.1 FW (1.3.2 BL) and it again stuck on 92% installing FW and the device showed the fingerprint.

Same thing happened to me, I forgot to note which fw I was upgrading from, but it was to the latest 1.11.1 Suite version: 22.5.3-linux-x86 Device: model 1

The upgrade hung at 92%, clearly waiting for the confirmation of the fingerprint on the device. Is there any reason we don't publish the fingerprints of the fw images on the firmware change log page?

@STew790 Do we know which versions this error flow come from?

I just saw this updating from FW 1.6.3. I think it's safe to assume that all those below this might be affected.
