[General Discussion] QF001 (ROCO K706) Head Units with UIS 7862s (not FYT based) [read first post first]

[one_goldern_heart]

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
• More codes are here https://forum.xda-developers.com/t/...uis-7862s-not-fyt-based.4525675/post-88055377

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://forum.xda-developers.com/t/...s-with-uis-7862a-7862s-not-fyt-based.4541261/

Dedicated thread for gaining recovery access: https://forum.xda-developers.com/t/...uret-s4-s8-uis-7862-headunits-no-fyt.4538107/

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.
- how to change boot animation: https://forum.xda-developers.com/t/...uis-7862s-not-fyt-based.4525675/post-88086835

- 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)

- GPS tweak: https://forum.xda-developers.com/t/...uis-7862s-not-fyt-based.4525675/post-88112693

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...

1. Any guide on how to install nova launcher/custom launcher? is it from Google play store? or .apk.
2. I cannot connect BT Teathring from my samsung s22 ultra and have internet. I get internet only by connecting to home wi-fi. I want internet on HU to say use google or youtube. I can stream music via Zlink with wire and wirelessly.

1. Nova launcher is on Google Play store
2. You can connect the unit to your phone via wifi by making a hotspot on your phone. Look for it in your network/connections settings on your phone. I had to force it to 2,4Ghz for it to work. That is no deal for me. I have stable internet for months using the 4G data plan of my phone. No need for BT Tethering.

 

[divxdvd]

Seller sent me this.... New 10.33" screen with 1600x720 QLED screen. Thoughts?

He also mentioned they will be on sale June12th....

Thanks @Clyde72 ; I am aware of hotspot but BT tethering doesn't drain battery.

I think the next update will bring new features like new launchers and Firmware update over the air.

 

[Clyde72]

Thanks @Clyde72 ; I am aware of hotspot but BT tethering doesn't drain battery.

No idea as I use hotspot mainly. I misunderstood and thought you were looking for a solution as you only can connect to your home wifi... Only for making occassional calls during longer drives I use BT connection.

Personally I wouldn't upgrade the screen to this or even the 2K model. More pixels means more work for the CPU even in stand-by and for a car the original 1280x720p QLED is more than enough in my opinion.

 

[Gyovany96]

Is there a way to change the Speedometer source from GPS to CAN on the homescreen widget? Sometimes due to poor GPS reception it shows fake speed or even ghost speed when the vehicle is stationary.

Or maybe some more Gps tweaks? I've already done the tweaks posted on OP.

Here its error:

Full video about crash:

View attachment 5929889

If you'll search info in the internet, the UMS512T is equal to UIS7862s.
Benchmark, Antutu, etc. don't give you anything about use feeling. The unit work good for most of the time.

 

[Astralech]

Is it possible to automate the screen brightness and Google maps bright or dark theme by head lights on or off?

I have it marked that it should change with the headlights, only it doesn't work. Once I drove under an overpass the theme changed to dark with the headlights, then when it got dark the headlights turned on and the maps stayed bright. The next day I started after midnight and the maps were dark from the start. The switch to the light theme happened around sunrise time when the headlights were still on.

I don't think google maps dark theme can be controlled by headlights. The google maps app is also missing the "Themes" option in settings, which is available on my phone, this should allow the app to match device theme. I've tried different versions of the google maps apk, all missing the "Themes" option. But navigation from google maps will switch to dark mode.

I've been using Here WeGo as an alternative maps app, it has option to force dark mode and maps download for offline mode.

Hello everyone, please tell me if it is possible to install magisc on this device to install Moto Dolby Audio / Audio FX Port or Dolby Atmos Port
OnePlus 8 or ViperFX. The fact is that when I connect my smartphone via bluetooth (there is root access and Moto Dolby Audio), the sound becomes much better and louder, and I would like to be able to do this without connecting my phone. maybe there are some other ways (without magisk) to install these AudioFx please tell me

Hi all, if anybody would like to test a very early alpha version of NavRadio(basic), they can find it here:
Download NavRadio BASIC for QF01

it's incomplete, full of bugs, it surely crash here and there but still usable.
I have enabled Google Crashlytics to help me debug all the crash and ANR so more people use it and more i'll fix it.

The full version will come when the free version will run smootly.
Enjoy


NOTES:

- Autoscan is done by MCU and it's fixed to 18 stations. Anyway you can use Autoseek function to find more stations or add new ones to the existing ones.
- The first frequency at startup need to be fixed.
- Sometimes you can hear the sound muting for a second, it's because the ROCO service think that navradio is a player and not a radio. I'll look for a fix later on..

After two days of use noticed two more bugs.

1. Crash every time when google maps voice navigation start speaking.
2. When signal is low on selected station, it starts AF (not in background but hearable changing frequencies) and find better signal on other frequency. Then changes selected channel to some other pre assigned channel from different radio station.
For example: select ch. 4 (HIT FM 95,00mHz), low signal, AF start searching, find better quality for HIT FM at 100mHz, then switches to ch. 6, set ch.6 to 100mHz.
At ch. 6 previously was some other radio station at other frequency.

1.ok I'll check it.
2. How does the original app work? Does it the same?

 

[Zlatko580]

I have to check, but I didnt noticed that bug at stock radio app.
About AF in background, it is not possible to achive because its MCU releated?

Where did you mark it? Can´t find any option.

I am very disappointed about this unit. Sleepmode does not work, whitelist to, stock radio app don´t start automatically after cold boot and Maps is only in bright mode. I think i´ll return the unit and switch to an FYT.

Android Auto via Carletter wireless not working with 0508 FW.
Any solution?

I think Carletter app can't share WiFi hotspot thats the problem.

Update about this problem:

I deleted and reinstalled Android Auto app on my phone and the Wireless AA worked only once on the first run.
After that I reverted back the version from 9.5 to 9.4 and I got it work again more than once till it started the fail again randomly.
I am 100% sure about that the fault is caused by the phone.
Maybe the Carletter app version is too old for the latest AA. But it says it is up to date.
I haven't tried the Zlink yet because it is Unactivated to me.
