I’ve found several posts of people who had an issue which required externally flashing the firmware to Nitropad, but no detailed explanation of how to do that.
In some cases, posting a laptop to Germany might be very expensive. In my case, I have to flash externally, because without that I’m not able to install the newest Qubes on x230. This is because of a bug/issue beyond my control, which you acknowledged happens to a small percentage of x230 which leaves me with an outdated system for now a very long time. I am in contact with someone via email, which is extremely slow - it has been months now that I keep receiving responses that are actually not getting me any closer to getting this solved. I understand your workload, but perhaps posting the info somewhere would mean that you get less direct asks for the same thing and those of us who have the issue can try to solve it?
This page could be updated with information on how to externally flash → Firmware Update v1.4+ - Nitrokey Documentation
Or else, can I please receive support around this issue, it’s been a really, really long time I’m waiting.
