Thank you. Unfortunately, I do not have any TTGO boards as of now therefore I'm not able to test and add support

The project does not include any external sensors/peripherals interface. It is only the UI interface based on LVGL. This is because the original C3-Mini board does not have any IMU....

For extracting, editing and repacking of watchfaces refer to this forum: https://4pda.to/forum/index.php?showtopic=1075503&st=20#entry122900599

I'm not sure about what you are trying to achieve. If you are talking about the watch firmware then check here for DT78 https://github.com/fbiego/dt78

@abidkhancu have you tried changing the language from the Chronos app? (See image below) If this does not work then it might not be possible

Probably they did not include other languages in the firmware, it's usually impossible to change the firmware

Do you have samples of your bin files from MibroFit?

the structure of these watchfaces is not the regular bin file which is editable by Chronos. Unfortunately, this structure has not been reverse engineered yet

the watch language is defined in the firmware which we do not have control of right now. For now, you can only edit some watchface components
