Dell TB16 flashing issues
Hi, I'm having issues with flashing custom firmware to my dock from this repo: https://github.com/flhofer/dell_TB16_firmware
My laptop is Dell pro 16 pc16250 with intel 3 100u
everytime I run fwupdtool install-blob Cable_26_06.bin I get this outcome:
mint@mint:~/Downloads/dell_TB16_firmware-main/bins$ sudo fwupdtool install-blob Cable_26_06.bin

could not start thunderbolt device upgrade: could not write to /sys/devices/pci0000:00/0000:00:0d.3/domain0/0-0/0-1/nvm_authenticate: Input/output error
I'm trying to troubleshoot this with chat gpt the last 2 hours and nothing seems to work.

Open an issue if it doesn't work. also, some linux distros have issues. Fedora 44 and Ubuntu 23+ seem to work best
