I have tried with both USB ports but have had no luck. It simply does update start then end straight away.When did you upgrade to android 9 did the full formatting?
Try to update using key1 to ground and turn on HU.
1. Format a USB to FAT32 first, then decompress the upgrade file and only copy files to this formatted USB.
2. Insert the USB to the unit's USB slot.
3. Turn the key to ACC level.
4. Press the RST button on the left of the panel, then turn off the key at once.
Then turn the key to ACC level again after 5 seconds.
5. Then the head unit will upgrade automatically.
Only one usb slot suitable!
This is a good idea.@****-jones do you think it would be a good idea to flash the following file using the PhoenixSuit considering I am unable to update the regular way, or would this be a terrible idea.
Thanks again for all your help
I am running just Android 9
Yes, bluetooth does not work on this firmware. There is no solution yet.My pleasure.
I tried a few of your firmwares and they are all great with everything working but the one I like the most, the Bluetooth is not working for some reason. Do you have any idea why that is. I have got BC8 in the config as usual and I know that the Bluetooth is working as it is fine with the other Android 9 firmwares. Just not on this firmware which shown in the image below.
When clicking the Bluetooth icon on the Home Screen, nothing happens.
If the HU has two USB ports, then only one is suitable. It is necessary to determine which one. No need to enable usb-debug.I am having trouble when trying to install the USB drivers on the PC. HU is in PC update mode. No new or unknown device showing up in the device manager on the PC. I have tried different PC's and different cables. USB-debug is enabled on HU. Cannot figure out what goes wrong.
can i upgrade my unit with thi link that you post ?I am running just Android 9
I tried flashing
and now I am able to update normally, just going through the various firmwares you have here https://cloud.mail.ru/public/CqfB/vp9x56MyE/Android 9/
to see which one suits best.
Is there any that you would recommend & do you know if there is a pathway to Android 10 on these devices?

I have a XTRONS d771A 1 din headunit :
CHIPSET : AllWinner UltraOcta-T8 Manifacturer Allwinner
Processor ARmV7 processor rev 5 (v71)
ANDROID VERSION : 7.1.2
MCU VERSION 5.3.19-125-0F-453101-190112-HY1702
version system v9.2.2_20180117.190333_TW2-HUY-FD
First of all, I would like to say that @Rottgrub is ultimately right, and you should not try to flash MCU if not absolutely sure / have a backup image of yours and ready to brick the HU.
