3. Hold back button for 5s to restart MMI box.
4. Should enter upgrade mode automatically if it detects USB stick with FW. (Don't turn off car)
5. Wait for upgrade to complete.
Is this how you understood this as well? Not sure how the screen switches between idrive and MMI during this procedure. |
Thank you. I thought that he may have been given a different procedure to force flash the update.
The above procedure is the same one used for Carlinkit and Bimmertech and maybe other units. I tried it with the RoadTop firmware but unfortunately it didn't work.
