Copy the .bbf file in your chosen language to the root directory of a USB flash drive (Not within a folder). All files have the English language, and if all files are added, the chosen languages will be English and Czech.
Insert the USB flash drive and push the reset button. The bootloader will automatically compare the installed version with the one on the drive and, if newer, will automatically offer you to flash it.
Confirm the update by selecting the "FLASH" button and pressing the knob.
If you have received the error "Firmware in the internal flash corrupted" use the alternative method below.
Updating from firmware pre-4.4.0
Starting from firmware, 4.4.0, the MINI+ has a new bootloader. This might cause some trouble when updating the firmware to version 5.1.0 and above. In this case, download firmware 4.4.0 or 4.4.1. The downloaded folder will have two files. Flash the printer firmware with the two files in the USB drive. After that, flash the latest firmware as usual.
Alternative method - older firmware release
It is not possible to flash to the same, or an older version of the firmware release, using the method above. To flash an older firmware the procedure is as follows:
Push the reset button, immediately followed by double-pressing the selector knob.
On the new screen, confirm the update by selecting the "FLASH" button and pressing the knob.
If it repeatedly only boots the printer and gives you the home screen try to format your USB flash-drive or try a different one. Even if the flash drive works with G-Codes and printing, it may not work for flashing the firmware.
