Flashing firmwares
Note
Everything you do with your printer is at your own risk. I am not responsible for any damage you cause to your printer.
- Obtain new .bin firmware. Original firmware files can be found here: https://fw.niim.blue
Warning
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) or you will brick your printer.
-
Open niim.blue. Connect your printer. Prefer USB connection (firmware process will be faster).
Open the printer's "Gear" menu, enter the new firmware version (it should match the version of the bin file).
-
Press "Upgrade FW" and select the firmware file.
-
Wait for flashing to finish. Please keep the NiimBlue tab in the foreground.
-
After flashing, the device will be unresponsive for a few seconds.
