Thanks for sharing your experience , i had a similar unit with same chipset and MCU, i tried multiple ways to get the firmware update using flash drive or microSD(using adaptor) unfortunately with no success.

firstly i formatted the flash drive (fat32) then extracted the zip file and copy the ATCUPG folder into the flash drive , rebooted many times while trying system upgrade where i got the following :

i also tried to add the the zip file by itself to the root of the flash drive once and add the loose files without the folder into the flash drive which didn't work neither .

finally i tried to add the mcu file to the root of the flash drive which worked and i was able to upgrade the mcu as per the below image.

i am not sure what's wrong and i would appreciate if you guys have similar experience to try to guide me through the process.

Thanks!

I had this problem.

The only way to update is to use spflashtool
[Android Head-Units] ahmad.alaa:

Hello,

Have you found a solution to activate? My vendor said they will activate, they are terribly slow. It's been a month already.

Thanks

Hello! My device find the MCU upgrade, but can't find the image for the upgrade from the same usb key... Have you some ideas?
[Android Head-Units] papachaca:
Hi

we are in the same situation, i saw your post on xda also. I tried flashing a metazone, logo and preloader from some 1024x600 and you can get a better resolution, but still gonna be landscape. Try installing an app from playstore , screen rotation app
[Android Head-Units] papachaca:
Hi, do you still have the firmware, can you reupload it. Looks like the link is broken or something. thanks.
[Android Head-Units] kubl_tg12:
Hello. Could you please upload the firmware to Bosion B200 AC8257 4G the most current, stable from MCU files. Thanks in advance. And another question, does CarPlay work stably? The main thing is that the regular radio would work

Hello everyone

I'm attempting to update my head unit but every time I tap on upgrade, it warns me that I will reboot and I hit okay & the system will reboot but nothing ever happens. Am I missing something?
[Android Head-Units] kubl_tg12:
If the update file is lower than the firmware version on the device, it will not work. Firmware downgrade only via flashtool
[Android Head-Units] David090491:
Have you solved this problem?
[Android Head-Units] just a bird xo:
It's not lower. What I'm getting at is my device doesn't even attempt to do any type of updating. I have an Android 11 version which I'm trying to update to but all my device does is prompt me that it will reboot when I tap on upgrade & then it just reboots when I tap okay. It doesn't try to boot into recovery or anything. That's my issue.

View attachment 5944081Hello everyone, friends, please help me find the firmware 768x1024
[Android Head-Units] papachaca:
i dont understand why is so hard to find that firmware, can you dump and share your firmware? I've been searching for a while and found nothing for vertical screen
[Android Head-Units] David090491:
I still haven't found anything
[Android Head-Units] papachaca:
looks like the only option is to extract and modify the lcd factory configuration of a horizontal firmware and convert to vertical, but i dnt know how to start
[Android Head-Units] David090491:
Unfortunately, I am powerless here, I will try to search further. Have you tried the firmware from xyaudio 5760?
[Android Head-Units] papachaca:
xy firmware have different mcu, they dont work and cause black screen.
[Android Head-Units] kubl_tg12:
Read this topic all your life and just as carefully on (https://4pda.to/forum/index.php?showtopic=1014593&st=0)

they tell you how to edit the firmware file to change the resolution
[Android Head-Units] David090491:
Unfortunately there is nothing about 768x1024 in this topic
[Android Head-Units] papachaca:
Hi, this is a temporary fix I've done to at least be able to use this HU:

Download this file https://drive.google.com/file/d/1H093Y8__SC9E45f5cm-HD-AxQ8W8_YzH/view?usp=sharing , unzip , first flash logo.mrf, in flashtool select only the logo file and download only, if it doesn't work, then flash the metazone, I've included a preloader file, but it make no difference in my case. You have to press reset if the unit doesn't reboot by itself. The unit will boot with inverted portrait logo at full screen, then it go back to landscape , but you're going to be able to use the unit. To be able to turn the screen to portrait, you need to install any free app from playstore, any works, just search rotation control in the playstore. The manufacture of those unit, remove some important setting from android to avoid user modified their system and make harder to find a solution. Some manufacturers leave those settings so you can choose from portrait or landscape mode.

I manage to root the unit following this guide

, once rooted you can install an app easy dpi changer, with this app you can change the resolution very easy. The problem i go is that when i change the resolution to 768x1024 , the unit act like landscape mode, the width if fine, but reduce the height .

The thing is that you can still with the unit, but not as it should.

This head unit is made to run in landscape mode and the manufacture worked hard to avoid user to change to portrait mode, so i think the only way is trying to find a way to modified the rom and patch with the missing parameters for screen orientation. I tried adb following this guide https://medium.com/@navalkishoreb/r...-using-adb-commands-not-emulator-94ab1a749b87 and i it doesn't work to force portrait mode .

I think this guide should work https://boundarydevices.com/set-android-default-orientation-to-portrait-mode/ , but i don't know how to apply the patch to the android rom

Just entered this world of AC8257 with this system information

Android version10

Hardware Information AC8257 - 8 Core - ROM 64GB - LPDDR4 - 4GB - 1024×600

Kernel Version 4.9.117+ #1 Thu Aug 5 10:24:03 CST 2021

OS Version KC160101-P01 - 0 1.1.4.9.1 - - 20210805

(CU Version M32 - 20210626-11-BD2-57

Have tried to search for any solution to my small problems:

1 not possible to modify the content of the (2) home/startscreens. Not able to delete/remove any apps, or add apps. No way around this but to download another launcher? Or is it just a matter of the right user with the correct priviligies, passwd?

2 no speed limit settings available in Google maps, and not possible to delete G maps in order to reinstall. I guess the G maps are installed in a location where speed limits are not available. Or old version of OS that not supports Speed Limits? Therefore it will not work even after upgrading to latest version of G maps?

Can I flash this firmware on an Junsun V1 Pro ?
[Android Head-Units] ahmad.alaa:
here is the same

did you manage to solve the problem?
[Android Head-Units] taona04:
How's it going mate

Sorry to report that i never found the solution. Something is up with that "android12" version. I've had to revert back to android 11 as well.

I did notice however that in the android settings, if you change the display, to make it smaller (zoom out), when you open Qlink, it reveals extra settings. In these settings i was able to fix the night time issue with android auto. So now it switches to night time and day time automatically and it works well.

On another note, i tried extracting the "android auto app" from the android12 version (Yes instead of wireless qlink, this one uses something simply called android auto). It installed and it automatically connected to the phone the way that the adnroid 12 version connects. The problem is it keeps spinning and loading. If i can get that to work, it will be as simple as removing the qlink app and installing this android auto app to get the android 11 version working like the android 12.

My guess it that app is obviously linked to the phonelink version on the android12. It's a newer version compared to the one on the android 11. I tried updating to this newer one but it never works. I tried completely removing the phonelink app so i can install the newer version but this doesn't work eaither for the some reason.

I'm happy to upload the apps so you can give it a try. They might mess up so system so you might have to refalsh it after. It's just apks

I have just had my 360 cameras installed but I can not get them working.

I'm using the original android 11 firmware from the beginning of this post. Does anyone know what settings I need to change to enable the new cameras. The original reverse camera seems to have automatically stopped working as well but I was under the impression you can choose to still use it or have the new 360 rear camera also be the reverse camera.

The cameras came with no installation instructions but what looks like red power cables at each camera and 4 on the cradle end in the back of the head unit but the installer said they don't need to be powered.

I'm also not sure if I actually have the 360 panoramic app installed as I have no shortcut for it but if I go into Android settings > apps, it's listed there so I created a shortcut for it and when it opens I can only access and modify the settings. The car/brand and calibration and align options cause it to crash.
[Android Head-Units] AML276:
Has anyone tried the B200 WIFI 1024x600 2023.02.16 firmware and mcu update from 4pda? It apparently fixes the issue of carplay/hotspot automatically enabling on reboots
[Android Head-Units] satcheee:
Yes it works perfect !
[Android Head-Units] AML276:
I ended up installing it last night and so far so good. Carplay hotspot hasn't come back on again, but wifi seems to take a few seconds longer to connect. At least it's still quicker than realising the hotspot has enabled itself and then having to turn it off to get wifi back.

Did your screen in general seem a bit darker on this firmware?
[Android Head-Units] AML276:
Decided to give the 2023.02.16 firmware a go and with it came an online manual (handbook app/icon) and although it detailed the AVM software when I followed some of its setup instructions to configure the cameras within the video menu I then got the 360 panoramic view app to appear. On opening the app I get a message about 3D surround view not enabled with occasional flashes of either 1 camera or multiple cameras looking like you're fast forwarding a VHS tape then after about 10 seconds the app crashes. I've tried changing from 720p to 1080p and between 25 or 30hz but they all have the same affect in the app.

Can anybody point me in the right direction on what to do next?
[Android Head-Units] satcheee:
Ok if anyone else can chime in im having a few dropouts not many but a few with carplay android and apple anyone else having the same on the 2023 firmware ?
[Android Head-Units] AML276:
So if you buy your head unit and 360 cameras from different sellers at different times is there no way to get the software activated?

[Android Head-Units] Blackwatch:
ve just bought a stereo from eBay, it looks like ive been sold a second hand unit which is another story that I am taking up with them at the moment. Is there anywhere I can get a manual for this stereo from any where please?

I know it is fake android, its running 9 instead of the advertised 12. Maybe I can get a new rom installed?

These are the system details shown....
[Android Head-Units] TorstenH:
Funny that you're writing in a thread dedicated for AC8257 based units having no glue what type your unit is. 🤣

You need to use the app CPU-Z to get you system details. Another and maybe even better approach is to google for your MCU version.
[Android Head-Units] Blackwatch:
I think mine is the AC8257_Demo
[Android Head-Units] real58:
Yes, I believe your car stereo is based on the AC8257 processor. The installed firmware is the same as what is installed on my car stereo. With this firmware I use android auto wireless.
[Android Head-Units] Blackwatch:
Is there a better ROM for it as this is a fake 12, according to the app I used to check it the ROM installed is 9.
[Android Head-Units] real58:
I don't know, maybe someone else can help us
[Android Head-Units] bambapin:
It looks identical (firmware and software versions) to my HU which is 8257_Demo based.

There should be an app installed with a digital version of the manual, maybe the app name is "Guide" but i'm not sure.

It contains the connection diagrams and sone basic information about the software.

If you are looking for the password: 8888 for the Factory menu and 0000 for the Original Car menu (the canbus brand and mode selection).
[Android Head-Units] AML276:
What app did you use to confirm the Android version as they are the same details as my unit and CPU-Z and aida64 both report android 12.
[Android Head-Units] lissics:
What is the API number shown in the report? API 29?

[Android Head-Units] kelaalke:
Guys who can help me find the firmware of the device.

I'll tell you a little about what happened, I bought an AC8257 4gb 64gb Qled android unit. I was playing around with the radio and decided to go into advanced settings and change the screen resolution, which caused the radio to stay on a black screen when I restarted it. The radio turned up perfectly, it even connected to Bluetooth. But he didn't give a picture.

I contacted the seller to provide me with the firmware (which is difficult because they respond every 2 days). To my surprise it provided me with a rar called flyconfig with a series of documents with the .flyconf extension. When the seller did not answer me again, I took on the task of looking for that unit but it was a titanic task since it does not say what model it really is. I made the mistake of flashing it with a generic AC8257 rom and now it only reboots after 5 seconds of being on. What I do? The PC still detects it. I have tried yt5760b and yt7260b but neither of them worked, still the same. Attached photos of the unit (from this forum)

Since updating to the Feb 2023 (android 12) firmware I've noticed that dab-z pauses the radio each time I turn the car from accessories to start the car. I stop the car frequently back to just accessories to leave the radio/screen on then after dropping off my delivery start the car and the radio pauses each time.

It didn't do this on the original firmware or the android 11 one at the start of this post.

I've looked at and adjusted both the dab-z apps settings for this and in the factory settings of the device but can't seem to disable it from pauses each time.

Anybody got any suggestions thanks?

The problem is in the firmware or in the radio. Don't know.

I return the old Android, everything is fine.

[Android Head-Units] themaang:
OK, so I got the HU to back up with SP flash tool. The thing is, I got the 128gb image 6gb ram and the process is different from all the YouTube and most forum tuts.

So my HU must be power on when flash-dumped, the memory read is different. It wants to do a dram flip test. That's not good for the chip, so a different approach is needed, a workaround.

Next is when the HU is on under the backup process, the screen goes white, and after 30 minutes start banding and fading.

So this is where I stopped the flash. I rebooted the HU and the screen was so bright I almost couldn't see the icons. But after leaving the HU on for maybe 1 hour, the brightness dropped bit by bit and the colours got back to normal.

This is a big concern because maybe the screen hardware will go if I attempt this again. This time I was lucky I think!?

So I'm interested to know, am I alone needing to power on this HU when flashing? And why do the screen go super bright after? I found in screen reset menu that the voltage is 5v max and when I drop “fade/volt/switch” the screen goes brighter. So my thought is that a/the battery is almost out off power when the banding and fading start? Do this HU even have a battery? Maybe I will open and check at a later time.

But for now, I'm leaving it as is until I find a safer way to dump a backup.
[Android Head-Units] ghannaiem:
I heared about how dangerous is Dram flip test .. still do not know how to dump the rom ... there is a thread in 4pda website for 5670b xy auto devices wich conatin the same Ac8257 processor and they write the process of dumping but it is not clear for me.. if it is useful for you and if it is allowed to post an external link tell me and i'll will post it here

Is it ok to try with your scatter ? .. are u able to flash the baxkup again or it failed ?
[Android Head-Units] themaang:
yes pleas share the link. 🙂
[Android Head-Units] themaang:
the scatter is made in wwr program. you can easily make one. so no use in giving you mine. its only when you upload a rom to your HU you need the scatter for that rom.

no I stopped the dump. luckily nothing happened to the unit, well the screen went all bright but that went back after 1 hour with the unit on. iv read that you can put the unit in recovery if holding on/off button and put a paperclip in res hole. haven't tried that yet. but you also need to have devmode active on unit and usb debug. I have fond the devmenu and some tick where I can make the unit host or device. don't know if that's how you get it to act as recover or transmitter? I will try this again on a later time. just need to read up some more on the whole process 😂

this is the flashtool version and drivers I use. don't use the Preloader just the program and drivers. and you also need Wwr
