When trying to flash the firmware, the printer shows the error: "Firmware hash verification failed! Firmware file is damaged. Try downloading and copying it onto the USB drive again."
Error name: Hash verification failed
Error code: #12607
This error is shown when the firmware in the USB drive is damaged.
Download the firmware and if necessary the bootloader, and transfer it to your USB drive. Make sure to unmount the drive from your operating system before physically removing it.
Insert the USB drive back into the printer and restart it to initiate the flashing procedure. In case the procedure does not start, reboot the printer using the reset button directly next to the knob and while the printer is booting up, press once the rotating knob (more about this on alternative method).
If the issue persists, the problem might be in the USB flash drive. Find any other USB drive in your household, make sure it is formatted to FAT32, copy both firmware files and repeat the previously described procedure.
