Ok . Recently i ****ed up everthing and got my headunit bricked with black screen but likely i recently made an exprimental backup and tried to restore back and it worked ! I think i found how to dump the rom .. and forget about the 4pda link it is not succeful ! ... what i tried was the video of Hovatek shared by @Wanted99 but the trick is using the attached scatter + through process use mt6761 as if it is your device + neglect the last three partitions as whethen the process the device will power off at 20% process and you won't be able to make the backup and i dont know why ! ...these 3 partitions are otp , flashinfo And sgpt. Untill now i have no idea what they are for , but other partitions was enough for me to bring headunit to life ! ..so follow the video and use this scatter and you will have an emegency backup .. thanks for your reply and sorry for my bad english .
[Android Head-Units] themaang:
thanks, no worries. I can understand what you are saying 🙂

so then I have one question. do you power on you're unit after you put usb in pc? or do you just put the usb in? for me my pc wont load the unit in flashtool if I don't power on? maybe you have other drivers? or maybe I need better usb cable?
[Android Head-Units] ghannaiem:
Yes , in every readback process you attach usb first then power on the headunit and process should start then after finish just power off..no need to plug out usb .. try both 4pin cable and 6 pin and see what works .. in 4pda they said 6pin but for me 4 pin that worked . And from head unit make sure to change usb settings from host to "device"
[Android Head-Units] themaang:
thanks, but then I wonder why my screen goes all bright? do ou also have that “problem”? I take 1 hour to get it back after, as if a battery needs charging?

thanks, yes I reed all that tread. I don't have a problem with my unit. im just scared it will brake if I atmpt another dum. I also get backlight when dumping, but it starts fading and banding as if the unit loses power.

why I want to make a dump. I want to root the unit so I can put viper4android and other apps. and if I brick I can reflash. but for now I will enjoy the unit in the car and wait til someone makes a good tut how to root.
[Android Head-Units] ena816:
Thank you very much, very helpfu.
[Android Head-Units] AiM2LeaRn:
BEFORE MAKING ANY CHANGES: be sure you have backed up by EXPORTING CONFIGURATION of you radio head unit by going to car/factory settings and typing in password and then choosing EXPORT CONFIGURATION to usb stick/drive. you will regret not doing this if you loose sound or touch functions and you have to restore. Configuration restore is the easiest way to restore missing device functionality.

To root the head unit you have 2 easy options to root this unit that will work.

OPTION 1-A

you can patch boot.img using magisk v22 or v23 (because older version of android, so use v22 to avoid harder complications) and flash with SPFlash tools or fastboot. (if using SPFlash tools be sure to use correct scatter.txt file)

OPTION 1-B

if you are lucky to have custom recovery such as twrp then you can just rename magisk.apk to magisk.zip and flash through your custom recovery.

OPTION 2-A

BE SURE TO HAVE

LATEST

WORKING ADB and

LATEST

ANDROID USB DRIVERS

CONNECT BOTH PC and RADIO HEAD UNIT TO THE SAME HOME NETWORK

(people will report problem with detection and commands but they skipped these 2 steps above, if you can not read and follow direction then maybe should stop here, i will repeat one more time....)

BE SURE TO HAVE

LATEST

WORKING ADB and

LATEST

ANDROID USB DRIVERS

CONNECT BOTH PC and RADIO HEAD UNIT TO THE SAME HOME NETWORK

download terminal emulator on Android based radio head unit (Terminal Emulator By Jack Palevich, for some odd reason Google Playstore has recently removed it after decades of being available, can still be found from other reputable sources)

setprop persist.adb.tcp.port 5555
setprop sys.rkadb.root 1
reboot

open terminal emulator again and type IFCONFIG to get your radio ip address

take note of your internal network Radio's LAN IP ADDRESS (not WAN), usually something like 192.168.1.x or 10.0.0.x

THEN ON PC

download the attached RadioRoot.rar and put the extracted contents in your adb folder.

adb connect (enter here your ip address number of radio head unit, for example "adb connect 10.0.0.2")
adb root
adb connect (enter here your ip address number of radio head unit, for example "adb connect 10.0.0.2")
adb remount
adb shell setenforce 0
adb push su /system/xbin/su
adb push su /system/bin/su
adb shell chmod 06755 /system/bin/su
adb shell chmod 06755 /system/xbin/su
adb shell /system/bin/su --install
adb shell /system/bin/su --daemon
adb push rooting.rc /system/etc/init/rooting.rc
adb install Superuser.apk

install's SuperSU 2.8.2

Open SuperSu 2.8.2 on radio unit and follow directions then reboot.

https://www.youtube.com/watch?v=W-bSxDz7w64&t=552s

NOTE: when performing method 2, you will have a few hard to get rid of error messages from Magisk if you ever decide to install Magisk. I personally had to reflash the factory system image using SP Flash tools to install magisk to get rid of super SU 2.8.2 root.
[Android Head-Units] themaang:
wow this is what I been looking for. thanks a bunch 👌🙂 will try this when I have successfully made a backup. I got the boot.img patched, but Magisk makes it bigger than original, so have to edit scatter to make a flash work with sp flashtool. but that was with newest version of Magisk. will try your tut. thanks again 🙂
[Android Head-Units] themaang:
i was in car today trying to send the radio.apk to my mail but no success. the thing is I have not installed the usb cables, im waiting on a wallmount usb extension. but I will solve the app for you tomorrow. promise 👌

Here is the Radio.apk, hope it works for you.

[Android Head-Units] AiM2LeaRn:
installing magisk to get root through TWRP is just one method, if thats the method you choose, just make sure the TWRP works for your head unit. im not sure if that twrp works with your head unit or not, you would have to ask elsewhere if that twrp works for your headunit.
[Android Head-Units] themaang:
no it won't 🙂 but I'm looking for a way to make one for my unit. if you have any pointers il appreciate your help. seen on GitHub some tools, but it seems quite hard if you don't know what you are doing. isn't there a program that can automate the creation of a TWRP? seen that you need the stock recovery witch I have and retrieving the kernel from the boot.img, but that's how far my understanding goes 🤯
[Android Head-Units] AiM2LeaRn:
you can see if there is a device tree for your build/model. if not create one using twrpdtgen and thats a start.

or you can just create your own tree and twrp with help of twrpdtgen.

Looks like my unit might have died today.

Keeps booting only to the 'Android' wording just after the welcome screen.

Maybe someone has a suggestion on anything I can try?

It woke from sleep mode this morning when I started the car but the screen instantly froze so after waiting around 10 minutes I used a pin and pressed the RST button. It then rebooted to a working screen but I then noticed pressing the icons on the pull down notification bar were reversed. If I pressed the first button the last button was triggered. if I press the second button the second last button was triggered etc so I pressed the RST button once more and now it doesn't boot past the 'Android' wording.

Am I going to have to search for a new unit?
[Android Head-Units] AiM2LeaRn:
use SP Flashtool and flash your compatible firmware. after flashing you may have to run calibration from car/factory settings to fix the buttons.
[Android Head-Units] AML276:
I think the panel type got reset on my head unit in the factory menu and as a result my left side hardware buttons aren't working. It's current set to double knob general (410). Is Full touch button the correct option?

UPDATE March 5: The cause of the power, home, back and volume buttons stop working and the touch calibration being backwards is due to putting the device into 360 degree camera mode. The supplier is yet to determine the reason why. Note: this is a Joyx brand purchased from Amazon.
[Android Head-Units] AiM2LeaRn:
not sure about 410 is right or not but i know there is a menu somewhere in the factory/car settings after you type the password that lets you configure the knobs or you can just "import configuration" assuming you saved it before you tinkered with the unit. if you cant figure it out flashing factory firmware with SP Flash should restore function but it will erase your customizations.
[Android Head-Units] AML276:
Thanks. I think I discovered the panel type option is actually for the software knobs in the top left of the screen so double knob seems correct seeing my previous unit was also double knob from memory.

Yeah I tried the option for reconfiguring the hardware knobs but it comes up blank. A couple of the videos I came across show that each of the button options should come up in the screen to tap in correspondence to tapping the buttons on the left hand side.

This unit was brand new, a replacement for the one I posted about last week that seemed to have died. Maybe it's a dud so I might send it back seeing I got it from Amazon. It came with Android 12 but only 1 GUI option so might try a different supplier.
[Android Head-Units] AML276:
OMG! I just fixed it. I've been going into panel learning each time. Apparently the left side buttons are under touch learning. Doh!

And after 2 years of hating that when I turn my headlights on the screen dimms too much even though I had the screen dimming settings turned off apparently you can change the brightness of the backlight at 5 different levels of which level 1 is when you turn your headlights on so I've now set that to the maximum brightness.

Update: would you believe fixing the side buttons broke the touch screen calibration again, and doesn't seem to want to reverse back to the correct orientation. So I've done a factory reset and all seems ok now.
[Android Head-Units] AiM2LeaRn:
yea when messing around with the settings things can get messed up, thats why its best to EXPORT CONFIGURATION (iviconfig files) to a USB stick once everything is working or before messing with any advanced settings. i would suggest you back them up now if you have your unit working the way you want.

[Android Head-Units] AML276:
Apart from the above issue with my replacement head unit, when I try to calibrate my 360 cameras I can't get them to calibrate/focus successfully. I step through the process using the 4 black squares template but I still get a blurry and double image view out of each camera. The process does improve the image but only to the point of clearing it up if I really focus at looking at the image so isn't useful in an emergency or reversing situation.

Does anyone have any ideas what else I should do? I have no idea about what fisheye table option I should use. I've tried about 3 different ones but it makes no difference.
[Android Head-Units] AML276:
I'm sending the unit back. Supplier is now claiming after asking for photos of the wiring harness that my vehicle is incompatible with 360 degree cameras even though my original ac8257 b200 firmware unit that came with Android 10 and that I've used successfully for the last 18 months was completely able to enter into 360 mode and not loose the power, home, back and volume buttons. This is on top of already supplying photos of the 4 cameras fitted to my car and the connector for the 4 cameras that plugs directly into the back of the head unit and doesn't go through the cars wiring harness as they wanted these photos to activate the 360 panoramic view app in the first place.

[Android Head-Units] AML276:
My supplier has sent me these update files as a fix for an issue with new head units that are shipped with Android 12. If anyone is considering buying a new unit please be aware that the Android 12 head units appear to have a bug or flaw in the firmware. The touch calibration and programming of the side buttons are not preset and while rebooting the unit in the first 24 hours or so causes no issues when you reboot the unit days later all of these settings stop working and reprogramming them doesn't seem to save it successfully.

The mcu file is dated February 1, 2024.

The B200 firmware file is dated March 11, 2024.

I won't have time to install it until this weekend. I'll report back once I have otherwise if anybody else uses it please let us know.

UPDATE: I got home early enough to install it this afternoon. It's an Android 13 image (API 33 according to aida64). It should fix my issue because I noticed in the touch learning section there are presets saved in this version, like there has been with my other older versions.

Only noticeable difference on first glance is that I think the ACC power off options now has a 30 minute and 1 hour option. I'm pretty sure all previous options I've seen has 2 days as the shortest.

[Android Head-Units] AML276:
I was able to successfully upgrade it via the internal on screen process. There's separate options to update the MCU and update the software. I did the MCU first as a test as it can be less problematic.

2 tips: use a USB drive formatted with fat32 and don't have anything else on the drive.

Hello,

I hope I'm on the right forum.

I have updated my workstation with the files B200 2024 03 11 ATCUPG.rar and mcu 2024 02 11 BD2.udp.

The update went well, the whole thing responds correctly except that I no longer have the possibility to save the configuration of the touch screen. The touchscreen configuration cycle is normal but when requesting "backup and exit", a message is displayed with the title "Tips" and the content "Save, please wait", the system restarts with a non-operable touchscreen.

Do you have an answer to this problem ?

Kind regards.

once canbus disabled to no canbus, everything goes back and text to speech works.

[Android Head-Units] auzideals:
Another problem with this unit, after many messages to the supplier, they told me it does not support "voice commnads", this explain a problem about google synthesis text to speech, where if i run IGO navigation, TTS pro voices does not work at all, no street names announced, not even directions lturn left or right, which explain my problem of canbus disabling my text to speech,(chasing the supplier for an update of canbus), this unit is great, except few things.

Hopefully in the next update will get "voice commands", this is what they called it, enabled

If any one has IGO working, kindly drop me a line which and where i can get it from
