Warning! Read first: Please do NOT unplug the USB or product when update is in process. The product will become defective, and will not work anymore. Do not switch off your vehicle either, until the product restarts again.
Which MMB do you have?
Select your MMB product with the directory below. If you do not see an older version of MMB, please contact us for update.
1. Unzip the downloaded folder using Windows computer. (If you are using a mac, try to make sure the USB is in FAT32 formatting).
2. Locate three files: (1) “Apollo_L6R_Z-DH1_JM1_ota_xx.ZIP” (2) “Apollo_L6R_Z-DH1_JM1_ota_xx.md5sum” (3) "upgrade_auto"
3. Transfer these files onto a USB thumbdrive with FAT32 format.
4. With the USB plugged into the MMB, plug the MMB into your vehicle. The update will start automatically. If it does not, go into MMB settings -> update -> click renew.
5. Wait 1-2 minutes for the loader to go to 100% and for the MMB system to reboot. It will return to your original car menu, and upgrade with red LED light for 5-10 minutes (depending on your USB reading speed), finally rebooting into the Android 11 menu.
5a. If the LED stays solid red for more than 15 minutes, do not worry. Keep the USB flashdrive plugged into the MMB, then unplug the MMB. Replug the MMB immediately and wait 1-3 extra minutes. Wait and see if the system will work again.
Do not unplug the device or switch off your car power when the MMB LED is still red and updating. It will cause the MMB software to break.
