NIIMBOT firmware collection
stable and testing directories contain original firmware images. They are not modified in any way.
Important notes:
- Use only the firmware for your printer model.
- Do not use different major firmware versions (for example, if you have 5.14, do not flash 6.x).
- Usually major firmware version should match the major hardware version. Example: FW 4.13, HW 4.01.
- Your device will be bricked if you ignore lines above. Have a nice day.
