Thingy91 1.4.0: Unable to update modem firmware: Desktop v3.9.3 + Programmer v2.2.0 + firmware thingy91_fw_2021-12-15_cfedfdfa

Have been trying for hours, and searched through the forums, but no luck yet. Modem firmware doesnt seem to load with the following setup. Downgrading to previous Programmer also gives errors. Please help.

How long are you waiting after seeing that warning?  The output in the debugger at the bottom doesn't appear to show any errors.

After waiting for 15minutes or so, the programming finally finished correctly. Closing this issue. thanks !
