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.

Flash with niim.blue (instructions). Everything you do is at your own risk.
