@jessie Thank you for your support

TLDR; Factory restore successful! (Thank you)

Actions taken, for your information or for anyone that faces the same problem:-

- grabbed the hex file.

- I am a member of ‘dialout’

- Without keyboardio plugged in:  
$ ls /dev/ttyACM\*  
ls: cannot access ‘/dev/ttyACM\*’: No such file or directory

- With keyboardio plugged in:  
$ ls -al /dev/ttyACM\*  
crw-rw---- 1 root dialout 166, 0 Nov 2 12:05 /dev/ttyACM0

- After 8 seconds, out of curiosity:  
$ ls -al /dev/ttyACM\*  
ls: cannot access ‘/dev/ttyACM\*’: No such file or directory

- Therefore safe to proceed.

The program ‘avrdude’ is currently not installed.  
$ sudo apt install avrdude

Setting up avrdude (6.3-2)

$ avrdude -patmega32u4 -cavr109 -D -P /dev/ttyACM0 -b57600 -Uflash:w:atmega32u4\_firmware.hex:i

Connecting to programmer: .  
Found programmer: Id = “CATERIN”; type = S

Programmer supports auto addr increment.

avrdude done. Thank you.

- and now I’m typing this on the keyboardio!
- unplugged it and tried it again. Still works.
- rebooted. Still works.
- I will flash again later with the [https://github.com/keyboardio/Model01-Firmware](https://github.com/keyboardio/Model01-Firmware), but without changing the Model01-Firmware.ino
- if that’s good I’ll try editing again. I will report back on this thread.
- Thank you for your help
