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.
1) Prepare an empty USB drive, format the USB to FAT32 and download the folder from the link.
2) Transfer the Petrel_fvd_p1-ota-xx.zip file only onto the root directory of your empty USB.
Note: Root directory means the USB main page. Do not transfer into a folder on the USB.
3) Rename zip file to "upgrade_pkg", format is .zip. Unplug USB from computer.
4) Plug in the MMB into your car USB, then wait for system to boot. Plug the USB with the update files. Then wait 10 seconds for update menu to appear. Click "Update immediately"
5) Product will return to original car interface. LED will turn red for 3-5 minutes, do not unplug and please wait.
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.
