I've encountered following problem after my bash script to update firmware crashed at some point.
Previously, I updated camera to 0.25.0 release manually using same files (SKU2 signed according to device S/N) and update was successful, I was satisfied with the camera tests. Then, since our enterprise has hundreds of those cameras (F455) I was thinking of automating the process of firmware update by writing bash script (I'm on Raspberry Pi 4). The first update to 0.19.0 went well but at some point after second update to 0.25.0 was launched the process was stopping at different stages (I was updating to 0.25.0 then reverting back to 0.19.0 because my script is still not ideal, on the other hand, if I enter all commands manually step-by-step as in script - update is successful, then I tried to add some delay between updates, but without any success). After one of unsuccessful attempts camera is not being updated to 0.19.0 anymore (and back to normal 0.25.0 - as well). Looks like after unsuccessful attempt the device's serial number can't be recognised anymore and here is what I have as an output now:
pi@raspberrypi:~/RealSenseID/build/bin $ ./rsid-fw-update --file F450_22.214.171.124_SKU2_SIGNED.bin --port /dev/ttyACM0 --force-version

Device does not support the encryption applied on the firmware. Replace firmware binary.
Please advise on steps that I can take to bring camera back to its normal state. Maybe factory reset or something else may help. Thanks!
