[Android Head-Units] blue_one:
Hello all,

it seems that there are some QF001 owners out there but not much informations. So i will try to collect everything and put it at one place.

The original manufactor is shenzhen jitu technology co. ltd.

These units are sold from Ossuret, Hizpo and other brands. This are the sellers specs:

The Android 12 is fake which is Android 10 in reality.

I have the 8/128GB Version myself:

Codes for the factory settings menu:

8888 - access to advanced settings

114477 - activates developer mode (Than you have to do the usual procedere: touch the build number on the system info screen several times until it says that you are developer now.)

22558800 factory reset

15935700 turns off sleep mode (Not tested by myself)

332211 - Shows temperature and clock speed

996633 - Exports some config file

Different firmware versions are inside this thread. Take care of the right MCU file and beware that clear user data is enabled by default on update. There is also a dedicated firmware thread: https://xdaforums.com/t/firmware-qf...s-with-uis-7862a-7862s-not-fyt-based.4541261/

Beside the faked Android 12 Version the head unit seems to be a good bang for the buck. I´ve paid around 230 Euros including VAT and shipping. The unit runs stable and powerful so far. Everything works as expected. The Android is a bit downcutted by the manufactor. There are no text notifications in the statusbar e.g. But i can compensate that with widgets.

Against the description android auto works wireless with my Xiaomi Mi10t pro. So that's also nice to have.

Tweaks, mods and others:

- my wire harness was labeled wrong. Key 2 and Key GND were swapped. So better check the cables before connecting. For me the correct wire names/functions were in the printed manual.

- replacement fan that fits my model: Sunon MF35101V21000UA99

- there's a sleep whitelist in the factory settings menu that prevents apps from being killed in standby mode (ignition off). That's very useful. I've whitelisted Google maps e.g. and don't lose my programmed route anymore if i turn off the engine for a short stop.

- tasker trigger for warm boot: detect any USB device connected. (You have to plug in something into the usb port, dashcam or pendrive e.g.)

- the status bar only shows a few symbols and no text notifications. Therefore I use a notification widget in combination with nova launcher. This way I can see all notifications in a widget which would be at the status bar originally.

- wireless ADB is enabled by default with root user. 🎉 The port is 9876. ( I've found that inside the build.prop)

- if you want to have a look inside the firmware you can use a rom kitchen tool like CBR

- how to change the boot logo:

1. If your player is 1280*720 screen, you need to rotate the picture 90 degree, and cut it into 720*1280 size, transform the picture to .BMP format.

2. If your player is 1024*600 screen, you need to cut the picture to 1024*600 size, transform the picture to .BMP format.

3. copy the picture into your Udisk root path, and then connect Udisk to the player. follow the steps settings-factory-8888-Logo set-then you can see your picture and select it- click update logo.

- enhance the microphone and call quality by using the external microphone and disable the internal microphone by masking two pins of a ribbon cable. It's explained inside this thread (link to post will follow)

Known issues:

- "hey Google" (activate the assistant by hotword) doesn't work

- no car speed dependent volume control (manufacturer says it would be implemented later)

- the firmware is a debug release which is a serious security risk (every app or malware can get root access through ADB shell). On the upside you can also get root access through ADB and do everything you want

To be continued...

Cheers
