Hi there!
I really need to change some factory settings on my android HU. Anyone here who can help me?
Thanks!!
How can i post an image??
It would help to know which HU you have. 126 or 1260 are used by many HU but 8888 and 3368 is used by some brands too. Allwinner based HU have a more complicated code. Go to the general settings menu and hit the gear icon then type the code to get into factory settings.
Greetings!
Browsing the forum I have figured that currently(January 2020) no custom ROM is available for PX6 which came with STM32 MCU.
As probably many owner have noticed the stock ROM has many flaw and severe deficiency/complete lack of customization.
As far as I know, sadly no Hal9k ROM development is planned for STM32 model currently. :crying:
I think many head unit is already or being shipped with STM32 MCU and I have a feeling that many hobby hacker (who can only install a ROM) including myself would be grateful having a sophisticated ROM for this model too.
I would like to ask owners as well to use this thread and express if they are also in need for a custom ROM.
Thank you! :highfive:
I need rom
OS Version: KC1E0101-PA1-1.1.4.3.1-BLINK161-20191115-701F
MCU: STM32-20190918-11-KC6-37
Hello to all!
After some days owning one of our favorite HU I gathered some info I want to share with yall. :cyclops:
Due to some random system reboot during normal operation I have also conducted investigation on heat dissipation. Simply put, these HUs has bad heat dissipation from factory.
The system during an AnTuTu CPU stress test hit 80 C which is not healthy for the unit and it can cause thermal shutdown as thermal throttling is not sufficiently implemented.
I added a medium sized heat sink and that reduced peak temperature to around 50 C.
To make the system cool on hot summer days I added also a 30x30x10 fan. With fan the peak reduced to around 40 C.
After the modification my HU is running stable, I was not able to make it reboot so far no matter how hard I use it.
P.S.: If any1 has info on the 4-pin connector next to the big white connector please let me know!
Update: added images with cooling added.

Hi everyone!
This post is for those who wants to know their device as much as possible or has issue with bluetooth / display or just curious or wants to update OS in future.
There is a hidden "Factory Settings" to access it you need to press: "Kernel Version" > "OS Version" > "Kernel V." > "OS V." > "Kernel V." > "OS V.".
Some settings in there are very useful actually.
For those who has fluctuating grey color at certain brightness I recommend "Factory Settings" > "Other" > "Panel learning" > "Vcom regulate value".
For those who want to make colors of the display simply nicer I recommend "Factory Settings" > "Other" > "Display Color Adjust Settings".
:good:

Hi Simbac,
before you flash any file, if your display is still responsive try "Factory Settings" > "Other" > "Touch learning" > "Step1: Screen learning".
If it does not help, you can find my config files:
One exported from main factory setting menu (android_config1579383003862..1) original file extension is ".1" but I was only able to upload to XDA as .img so please rename it if you want to use it
One from panel learning menu (BHDPanelConfig.img)
And one from touch learning menu (ts_config.xml)
After copy them to a FAT32 formatted USB drive you plug into your HU the updater app should launch automatically. My files are for "CONFIG" and "PNL" (panel) and "TS" (touch).
:good:

I hope you have success with them. By the way Simbac, I saw your old post you had a blue screen only on the HU. How did you get pass that?

If your device does not get pass the bootloader so cannot get into the Android OS then you cannot use this method to update ROM. Did you enable ADB via TCP?

You can find my video at youtube.com/watch?v=sDxmmYL-nIg
It can boot to android, because I can saw that my phone can connect to the HU's bluetooth. I already checked the wifi but it seems that HU don't connect to access point.
have you tried to enter recovery following this procedure? (remove spaces) https: //drive.google.com /open?id= 16CfginUDta01NfMxt7B3a8g0CyniUnit

You can try an "Erase with reset button". Note that all of your data and apps will be lost if it completes erasing and android should be in factory state after this erase.
Check my video here: link
Timing of presses is not exactly known neither the number of presses. I was able to start erase with most success by pressing 1+4 times. You know if you did right if white screen appears for a short time (at least on my STM32 HU).
Good luck!

Let me ask something.
If you enter recovery menu by reset button you can also navigate and select options there with the same button.
If you enter recovery menu by typing to terminal: "reboot recovery" than can you use the button again for navigation and select?

I see from your screenshot that you have the LESS ugly version of the UI than my recent unit. The radio app on mine is especially difficult to use. I'm been looking for the radio apk from a unit like yours. I was able to extract mine (it was called com.hzbhd.radio.apk) using "APK Extractor" from the Play Store. If you would post your radio APK I'd love to see if it would run on mine. Thanks!

No, using "reboot recovery" you have to use an external usb keyboard to navigate and select and the selectable option is different (example ther's not USB option, only SD) , but I don't know why

All right, it means that there is still hope to enter somehow recovery mode with reset button on my type of HU. It just matter of time to find the good sequence
Thank you!
P.S.: Where did you see having an "..USB.." option in recovery menu, can you share link?

I attached the extracted radio apk.
Please share a picture about your OS and MCU versions and tell us if the new radio works on your device.
:fingers-crossed:
Can somebody extract for me the car settings(vehicle/canbus) APK. Thanks

Thanks. I'll try to do it tonight when I get home from work.
Having an issue with hiding the status bar, no option in any of the settings menu or system menu. The system is not rooted so using most apps to enable immersive mode is non-functional, they also have apps that require no root but the keyboard won't work or it only hides the status bar for the home screen and no all the apps also I have no idea how to adb into the head unit. Wanted to see if anyone here had any clue on a fix or have had the dame issues and has a workaround. Thank you in advance.
I have a new PX5 Android 10
PBX80JCCLTrying to enable developer options, I tap the Build number 7 times and more and it does nothing.
I've tried many things and still nothing.
System is original and not rooted.
I need to see my usb settings and possibly change them.
Can I enable with terminal emulator?
Anyone have any ideas?

i ended up flashing a custom firmware and gave em root
Firmware: 8259P_军灿UI02v1280x720-国外_v27_20211201.zip
825x 20200426.093427
Car model: Mini cooper 2015
When trying to select the proper canbus type, I can see the item in the list "65. BMW.Mini" but the item is greyed out can cannot be select.
It used to be selected and work, I tried item "85 BMW.Mini" to see if it would give more option but nothing was working and since then I am unable to select the proper can bus type, which is #65 BMW . Mini.
I have tried resetting and reflashing the os, cleared all the cache I could think but issue remains.
I do not understand what is causing this.
Could someone give me a pointer or something, I don't know where to go from here.
Thank you in advance.
Oliber.
Hi after some playing around I got android auto working on my head unit with my samsung S8. I saw there was an update to the firmware and downloaded it but for the life of me i can't get it to install. I extracted all the files to the root of a USB stick and the update would start. As soon as the little android guy pops up it says error. After further investigating I found a file inside the other extracted files which was 6315_1.zip and extracted those to the root of my USB stick as well. Now when the android guy pops up the message is No command and the update stalls. Any help would be awesome. I tried searching but haven't found anything yet
Hi, hopefully you have solved this by now but just in case and to help others I had a similar issue.
Tl;dr you need to get into developer options and activate "Allow updates on startup" Car Launcher Pro allows this, maybe others do too.
Longer version:
Support couldn't help me but I accidentally stumbled on a solution myself. The below is a copy and paste reply to atoto support (it's disappointing they have not passed it on to you - assuming you asked them of course)
Start of email:
I have resolved my problem.
I installed Car Launcher Pro to look at the skin/theme options and needed to go back into system settings to change something.
However, when launching system settings from CLP it bypasses the stock ATOTO settings and displays full android settings. I was then able to see Developer Options and noticed one of the options was something like "Allow updates on start up"
I activated this option and I was able to update to the latest version successfully.
End of email
Note I can't remember if developer options itself was already activated or whether I had to tap the build version button in the usual way. Good luck
