Fantech MK921 MAXFIT8 One Piece Edition - RGB broken after loading official JSON, need firmware file
Hi everyone. Long day and completely stuck on this.
I have a Fantech MK921 MAXFIT8 One Piece Edition. I followed the official manual instructions exactly — downloaded the Maxfit8_OP.JSON from Fantech's website and loaded it into VIA. After doing this, all RGB stopped working except the encoder knob LED and Capslock LED.
Current state:
- Keyboard fully functional — all keys work
- Only encoder and Capslock LEDs light up
- RGB Matrix appears stuck on "none"
- Keyboard has been in bootloader mode (Drive E:)
- Fantech Discord support unresponsive for hours
- Their JSON file appears malformed — missing required 'lighting' property
I need either:
- The correct firmware .bin file for MK921 One Piece Edition to drag onto Drive E:
- OR a corrected Maxfit8_OP.JSON that actually works
I've tried every reset combo (ESC+plug, Space+B, ESC+Shift, ESC+Backspace), VIA lighting controls, JSON editing. Nothing works without the firmware file.
Fantech's support is Discord-only and they haven't responded. Any help appreciated. 🙏
