Hi, I have a half working Atreus, some things work as expected but some things fail. For example, I have a dual key configured for shift/A that does not work, and have another one that is Super/V that do work… Anything I do on Chrysalys have no effect on that. So I’ve tryed several things: - upgrading the firmware, - resetting EEPROM to the defaults, - downgrading the firmware - compiling the firmware, - flashing the firmware from Chrysallys and from the commandline, - setting the “erase everything on the keyboard” on flash - plugin the keyboard on bootloader mode and flashing from there on chrysalys. - sending `eeprom.erase` and `device-reset` using `focus-send` That being done, I’m stuck and the keyboard is still half working. Just for context, I’m using Linux. Any help is much appreciated. ---

Finally I found a solution to the issue [in this issue on chrysallis](https://github.com/keyboardio/Chrysalis/issues/1407). It seems something broke quite bad the firmware of atreus after 0.92 That said, I think that it could be great to have a better understanding of what happened.
