If you haven't seen my previous SonixQMK video yet, watch it here: https://www.youtube.com/watch?v=2MHtLEiXaXg After getting the open source QMK Firmware running on Redragon, Keychron, AJAZZ, and other common low-cost mechanical keyboards running the Sonix SN32F248 and SN32F248B chips, we now have it working on the Glorious GMMK Full 2021, which is using the Sonix SN32F268 chip. There is a larger risk of bricking your keyboard with this chip, because it is possible to erase the bootloader needed to load code. However, if you follow this guide step by step you shouldn't have any issues.
