New car, new headache - Android Head-Units

Good Evening all, I picked up a new car from auction this week and it has an aftermarket head unit installed.
It's an Audi A4 b7 2007. And I think I have identified the head unit as a xtrons model. (unable to post links)
I have a previous knowledge of rooting android phones and I suspect that the head unit has been rooted..... Badly... and it doesn't work as I would expect. Buttons do the wrong thing and there is an error code down at the bottom of the screen for
version mismatch 01.
There is also a beeping tone every 10/15 seconds which is highly annoying!
It is running the following aparently.
Android 8
Security patch 2017
Kernel 4.4 93
Build px5 malaysk 3.5 8.0. 0 OPR5
On boot it appears to be running a maya mod 3.5 or something similar.
Im quite happy to flash back to stock at the moment, as I havnt got time to be messing around with it. Which I will probably do in the future.
Where do I start to try and undo all of the garbage that has been installed and made it unusable?
Having not got it to this point, it's very hard to understand how to get it back!
Thanks in advance,
Tom

I am assumimg you have a MTCD type headunits..due to malaysk rom. (If mcu startss with MTCD or MTCE string then i guessed well)
If you think you have an xtrons px5
..then you have to find the mcu for the xtrons manufacturer to do an update. That error comes from being upgraded to mcu from other manufacturer....
Otherwise
So go to match subforums and search "mcu version mismatch" and you can override the error (beep and medsage will disappear)
On that subforum you can find android uogrades for the dame android 8 version or you can upgrade to android o or android 10....but you need to upgrade your rexovery partition first....search and read first

[AvinUSA] How can I upgrade my PX6 head unit from Android 9 to Android 10?

I have the Avin AVANT 4 Multimedia Navigation System for BMW X5 E53 PX6 head unit that came preloaded with Android 9. I'm hoping to upgrade to Android 10 but their customer support agent said that's not possible. It has to be possible, right?
I spent some time trying to flash the PX6 Android 10 image from ibus-app.de, but to no avail. The device detects the update.zip on my USB drive and asks to install, but when it reboots and starts loading from recovery mode, it fails with a Status 7 error.
Does anyone know if I can update this with newer firmware? If not, can I flash a different OS on there? I imagine this is a noob question but I can't seem to find much about the AVIN Avant 4 head unit.
The unit can run 10 as it is listed on the site as such:
Please choose CPU platform
PX30 | 2GB RAM | 16GB ROM | 4-core CPU | Android 10 (LHD Only)
PX6 | 4GB RAM | 64GB ROM | 6-core CPU | Android 10 + $49.99

Pretty sure it is the same as my Avant4 for my e39 which came with Android 10 out of the box.

It is very easy. What you need is this app - Mod Installer PRO. Of course like with any other mod, you need to ensure your MCU is MTCD, MTCE or MTCP.
My unit came with 10. What does that mod Pro actually do? Install a generic Android 10?

It can run Android 10. Their Android 9/10 PX6 units are physically identical. I was told as much by customer "support," and updating is theoretically as easy as following their instructions/installing their upgrade files.
The problem is that AVIN is a pretty shady company and wants to sell you a new head unit rather than let you upgrade the OS. Even if was just days before they launch the new OS version, if you bought the Android 9 unit, you're stuck with Android 9 for no other reason than because... well... if you want their official build of Android 10 badly enough, they think you'll pay another $450+ for it. Ask me how I know.
Yikes.
I could have sworn my unit was running Android 10, but now I am not sure. As soon as I get the car back from the mechanic, I'll check. If it is, I have various MCU and software upgrade files I can share.

Oh sorry, thought you wanted to upgrade from previous version to 10. Essentially this app allows you to upgrade or downgrade your Android OS.
For example, I got it to downgrade my Dasaita PX30 unit from version 10 to 9 in order to install Malaysk mod.

That would be fantastic. I purchased my PX6 E46 Avin Avant 4 unit just before they released the Android 10 version, and they’ll only give me the files for Android 9. I’d be very interested and would greatly appreciate it!
Sorry to bump, but were you able to check on that Kjricker? Would be great to get on the factory instance of android 10.

I'll bump this one more time as well. Did you find out which version you have?

Xtrons PB78FSFP PX30 quadcore Cortex-A35 MCU (FORD)

Hi All
looking through this forum it seems quite interesting and i want to explore this in depth when i get my android to work
i have bought a used Ford with the Xtrons PB78FSFP installed, but it malfunctioning, in the sense that it states Version Unmatched -01 and looking through this forum it seems that an MCU update might be the reason (seller had no clue). So my question is how do i find the right MCU for this model so i can start over and maybe get it to work properly.
Right now its running MTCE_AW_V3.71_1 (DEC 21 2020) but according to what i can google it doesnt fit this model
OS is Android 8.1

Erisin PX30 based head unit Android System webview issues.

HI all!
I have an erisin head unit in my vw golf and started acting up so i ran a reset. Still had the same issue so ran a 2nd reset. Still same issue. Turns out it is caused by the Android System Webview update. If i uninstall the update (yes its horribly insecure) google login, waze, and other apps sart working. HAs anyone run into something like this before?
(Android version: 10, patch level 2020)
Hallo, it's a known android 10 issue on px30, px5 and px6, MTCD/E, so far the only solution is to uninstall and disable webview and chrome updates. Try to write to the seller about a firmware update that will fix this problem.
