Upgrading from 4.14.2 and below to 4.15 and above requires upgrading the bootloader version to b2.

Upgrading the bootloader is not undoable.
After upgrading the bootloader you will no longer be able to install firmware versions below 4.15.
Do not remove power from the module during the bootloader upgrade. Doing so may render the module inoperable.

To upgrade the bootloader from version b1 to version b2:

  • Download dm4_bootloader_upgrader_b2.zip.
  • Unzip to get the 'image.hex' file, and copy it to a MicroSD card.
  • Download a firmware version 4.15 or higher, above.
  • Unzip to get the 'disting4.bin' file, and copy it to a MicroSD card.
  • Insert the MicroSD card into the disting mk4.
  • Power the module on while holding in 'S'.
  • "Confirm..." appears. Release 'S' to install the bootloader upgrader. Wait for "Success".
  • Power off and on again. The upgrader will run, and ask you "OK?" three times.
  • Finally it will show "Are you sure?" and then "Confirm". This is the point of no return. Press the encoder to run the updater. Do not remove the power while the updater is running.
  • All being well the module will show "Success". Power off and on again, and you should see the bootloader version 'b2'.
  • Now you can use the usual firmware update procedure (power on holding 'S') to install the new firmware.
