Hi, i have 4G version, can you share updated firmware? thanks :)

one more i have problem use wireless keyboard like a attached file.

Sometimes work mouse only and sometimes keyboard only.

thanks...
[Android Head-Units] dj.shauny.g:
I have no answers for most of these questions, however.

My unit would not connect to my ELM OBD2 at first. I had to go into android settings/bluetooth settings and change the password from 0000 to 1234. I then restarted and then i could connect to OBD2. Hope it all works out for you
[Android Head-Units] duvshi:
Hey.

for the auto hotspot issue, you can go to the phonelink app and disable Carplay as it require hotspot to work,

Xinbas is a difficult CanBus as they stopped their operationts a while ago so the protocols are unknown

you can use my version (2610pro) that have many Xinbas protocols

radio,

you can disable the radio complety buy going to factory settings and then moduls and disable the radio

about the OBD2 you need to go to the android settings and pair it from there
[Android Head-Units] apacatia:
Ciao, Thanks for the tips. In your opinion, buy another canbus module other than xinbas, can improve the situation?

As for "2610pro" is it not dangerous to downgrade Android version from 11 to 10?.

Thanks again
[Android Head-Units] duvshi:
In fact, all of the version are android 10,

The company just change the name, i can send you a config file that will say android 12 if you want lol
[Android Head-Units] BabayAbay:
I have successfully installed Android 11 Provider by @noiwid.

But, I lost access SIM Card. And Bluetooth can't work properly for me.

Previously I used AVM Application for 360 Camera. This firmware using the 360 Panoramic Application, the application worked but the back camera sometimes black/blank, and I like better use AVM Application.

Here is what my Device looks like right now:

And this is my previous device display. There is a 4G symbol on the top right:

Now, I can't get back to previous firmware because I not have the original firmware before :cry:

Who has firmware AC8257 (B200 - Core 8 - ROM 64GB - RAM 4GB - +SIM)? Can you share?
[Android Head-Units] taona04:
@BabayAbay Did you upgrade using flash tool or USB? I noticed when i used USB for the android 11 version, it gave me problems as well. Bluetooth kept on dropping and Android Auto wasn't being picked up at all
[Android Head-Units] BabayAbay:
I used USB. maybe that's why the problem.

But, I have never been able to successfully connect with my laptop.

Driver MTK was never detected on my laptop. Or maybe I used wrong driver. I am not sure.

That's why I haven't backed up my Firmware previously.

But, thanks for sharing @taona04 (y)
[Android Head-Units] dj.shauny.g:
Thank you very much! This worked and i have finally updated my unit. This was a very frustrating task to get done before hand and seemed impossible, however with you guide it was as easy as ABC.

My unit is now working as it should.

Thanks again mate really appreciated!

One fix I've noticed is Waze now follows the night settings chosen on android auto before it would stay in day mode unless I opened google maps and then reopened Waze

1 issue I have found is after a phonecall android auto will freeze and have to reboot the headunit to fix it
[Android Head-Units] dj.shauny.g:

Oder ob es für den MCU so wie Canbus ein Update gibt?

Or is there an update for the MCU like Canbus?
[Android Head-Units] dj.shauny.g:
This is a problem for me also, however i would only like to update if there is anything worth while doing. Surely the android auto thing could be a standard update to android?
[Android Head-Units] Tmontecio:
Olá, onde você encontrou esse firmware. Eu tenho uma unidade com as mesmas configurações, mas a tela é 768x1024. Alguém pode me ajudar?
[Android Head-Units] Tmontecio:
Olá, você tem a versão para tela 768x1024?
[Android Head-Units] taona04:
Não, desculpe, eu só tenho a versão que compartilhamos aqui.
[Android Head-Units] taona04:
I just updated to this and here's what i noticed

The UI is exactly identical

The WirelessQlink app has been removed, now wireless android auto just works similar to using a cable. It's much faster to start and smoother

The transition to night mode in the evening is more seamless and just works better

Overall it just seems more like a bug fix update. If the minor bugs bother you from the current firmware, you can update to this. Considering that it takes less than 5mins to do the flash process, for me i think the download was well worth it.
[Android Head-Units] taona04:
I'm starting to experience a Bluetooth issue with the Android 12 update. Noone can hear me when they call me. If I tap on the microphone of the radio, they hear that. But the moment I talk you can't hear it. It's as if it's specifically blocking my voice.

I mean it would be a cool function to block just voices in the background but it's an annoying bug. If I can't figure it out I might downgrade to Android 11

It has been very difficult for me to update from the USB but I have at least managed to get it to read the USB and I was able to update the MCU, because it does recognize the .UPD file but that's as far as it goes. Do you know how I can finish the process?

[Android Head-Units] dj.shauny.g:
Go down the flashtool method. Really quick and easy
[Android Head-Units] dj.shauny.g:
Is this linked to the internal settings of the mic?
[Android Head-Units] taona04:
It's same results for both internal and external. When you get really close to either mic, it sounds like I'm very far away from the mic.

The mic gain option should fix this but it doesn't do anything

[Android Head-Units] helman.cc:
I did it that way too, but the problem persists. Every time the unit reboots, the wifi is turned off and the hotspot is turned on. I also reinstalled the Android and did not configure the Android Auto to avoid it, but still the same.

[Android Head-Units] ramelki:
Hello everybody

Few days ago i bought an unbranded head unit with the following specs:

4gb+64gb

AC8257

4G sim socket and antenna

1280x720 IPS

7851 amp Chip

Wireless android auto

It is claimed to have android 12. After running two apps "fake device test" and "Aida", i got two contradicting results: the first states that it's fake and it is just android 9, the second (Aida) states that it is android 12 with API 29. I don't know which is true.

All functions are working, except with FM reception quality, which i guess is not an uncommon problem as i read in many threads.

The problem is that i can't find any information on the board that can help me looking for software upgrades or any customization.

I am attaching some pics may be somebody can help on this.

Have a blessed day.
[Android Head-Units] real58:
Hi, Have you tried increasing the radio sensitivity using the car radio settings?
[Android Head-Units] kukas87na:
Oh!

It worked for me too! Thank you!

Instead to reverse these two keys in the picture? Do you know how I can do?
[Android Head-Units] julemanden89:
What exactly do u mean?

If u have set the canbus to correct vehicle, then u maybe can use the SWC menu to remap the keys. But I'm not sure 😃
[Android Head-Units] kukas87na:
I mean, if I press forward it goes backwards and if I press backwards it goes forward... before updating the car radio even by selecting the right canbus I had a function in the menu that reversed the operation of the button, but now I can't find it anymore
[Android Head-Units] kukas87na:
Ok, I selected the wrong canbus, not knowing exactly which one I was based on the year of the car (mine 2015 but in the canbus I had to select the 2016 model).

Another thing

I read in some post behind that a user always had the hotspot active and wifi deactivated when starting up, now it's happening to me too, how can I keep wifi always active? Carlink is already disabled and since I have a 4g usb dongle I would like it to connect automatically like I did before updating to android 11...
[Android Head-Units] BabayAbay:
do any of you have problems using an external mouse & keyboard?
[Android Head-Units] TorstenH:
No need to use a mouse in my car. What's the use case?
[Android Head-Units] BabayAbay:
I need it for my family or passenger. So they can change any movie, music or etc, just with the mini mouse-keyboard.

So, I as a driver not too distracted when some people go to the front and just for change the movie, music, or volume.

Android 10

View attachment 5881865

I tried to install system updates from the post

and unfortunately it was not possible to detect this update from USB (made according to the video, unfortunately, in my options it is not possible to select the update, it only looks for it after selecting the update option and resetting the device)

I changed the UMC to the one that came with this firmware:

mcu_202206071001BD2-1559.upd

Unfortunately, after this operation, my FM RADIO stopped working, I tried to change the options, unfortunately, nothing helped until changing the MCU to another mcu_202211111001BD2-1157.upd. After this operation, the FM radio started working properly.

I found another update on another forum:

Link to the forum

>>> Link to the forum <<<

Firmware 8257 4+64 WIFI na 2021.08.05 ATCUPG

This software was installed without any problems via USB, only that it is still Android 10.

My question is, does anyone have an idea why this software was installed without any problems via USB and the others and this thread does not start at all on my radio?

He would still ask for advice because according to the seller, it supports the internet with 3g / 4g donge, unfortunately, after installing the USB dongle, it activates and there is no internet, is it necessary to set some options?

My donge is HUAWEI E3372 LTE USB Stick

Unzip both files and put them on an USB stick. Use an old one with small capacity (<32 GB). If the head unit is up and running the new fw should get detected automatically.

[Android Head-Units] noiwid:
Hi,

I suggest you to install an external APP like AIDA64 to really know what your hardware is.

It seems many OEM sellers artificially change these values... You probably only have 2 Gb of RAM, but your seller want you to think you have 4gb... and this system update uncover their ****ery!

you cannot install Zlink as they dont have the license for it, you can install it and pay for it if you wish but the phonelink app works well, you can force it ti work by going to settings-general-Carplay

and if you want android auto wireless you can open wireless Qlink
