solo key update fails with problem flashing firmware

[olof-nord]

Hello Solokeys,

I wanted to upgrade my Solokey firmware, but the update failed.

What do I need to do to correctly update to the latest firmware?

$ solo key version
3.1.2 unlocked
$ solo key update
Wrote temporary copy of firmware-4.1.5.json to /tmp/tmpigfaxwjb.json
sha256sums coincide: f36bb365bfddf75004f28af392ae1439192ca0ed821ef496084a75a00d05087a
Switching into bootloader mode...

error:ng firmware 100.00%...
problem flashing firmware!

$ solo key version
3.1.2 unlocked

Now it seems that the Solokey does not work anymore?

Trying to use the key to logging in unfortunately confirms that the device is no longer usable.

Here is the version info:

Problem solved! Just execute the update command once more and the device is back working again.
