Probably just updated to Bugs V4.2

Did you try changing the default launcher?

i am actually so pleasantly surprised just how great my audio is sounding utilizing the digital output from the head unit and into this $20 dac, and then from dac output RCA's into my 4 channel amp.
Before I was using just the low level rca output from the head unit into my amp and was actually having great results too it really did sound good. However, with digital output it is just that much more clearer and fuller sounding. Especially in the low subwoofer frequencies. With digital I can clearly hear individual base notes and when the tone of the sub changes with the note being played down to the most tiniest of change in tone, it's really that clear. Before with using regular preamp output from head unit the low frequencies were muddy sounding almost as if individuals notes were blending together making it very hard to hear individual sub bass tones.
I know I'm not breaking any new ground here lol just want to share my experiences and hopefully can help someone out in the future when choosing their audio routing.
Idk why I waited several months to even try the digital output lol I was happy with rca pre outs but still lol I see now why this is the better way to do it.
I do have a question, is this cheap dac I'm using harming the signal in any way? You can spend big bucks on dsp's I kinda gotta assume using a cheapo dac isn't the best? Idk it sounds freaking amazing lol

I have solved some issues, thought I'd share:
1. To make clock sync I actually had to select a different canbus profile via 8888 menu - for Ford 2007-2012 LOW rather than HIGH, even though mine is after lift from 2011. Now clock syncs properly.
2. Ossuret sent me this (see first image) power filter to solve high pitch noise - I will install it along with Axton A542DSP amp/dsp. Will connect it via toslink and let you guys know how it went. Axton has a dedicated harness for Ford vehicles (see other attachment).

However, I have an issue with customization:
A) I want to use my steering wheel to change between spotify and maps, but the changer is fixed with a default selection of video, music app, maps etc. which is annoying.
B) On spotify the top bar overlaps part of the application, any way to change it?
C) How can I set NavRadio as my default radio app?
D) Has anyone set custom apps for side buttons?

Cheers.

for B: I use Immersive Mode Manager to display spotify fullscreen without the top bar.

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://xdaforums.com/t/general-dis...uis-7862s-not-fyt-based.4525675/post-88055377
• https://xdaforums.com/t/general-dis...d-read-first-post-first.4525675/post-88203789

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.
- how to change boot animation: https://xdaforums.com/t/general-dis...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://xdaforums.com/t/general-dis...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...

For whom that's interested and is annoyed that display time is out of sync with atomic network clock time.

Myself don't use 4G network, but WIFI hotspot from phone.

Each time when I opened the GPS test app, time changed and was out of sync by 2 to 4 minutes, also when I forgot to put hotspot on my phone on, after that it was taken the GPS time sync by default after startup,
So first taken my right hotspot network time and changed 30 seconds later to the out of sync GPS time, it was also out of sync with my OEM Opel board computer display.
With some hassle I could changed that back but needed to be sure that hotspot was always on before starting the car.

Think I found a solution.

Note, I don't use sleep mode, always have a fresh cold start, unit starts up with firmware date and time, 09-01-2023, 12:05:54.

After going in the factory 5544 GPS setting, changed on first tab screen "agps" the server SUPL host to supl.google.com, changed port to 7276 (seems secure port), but you also can leave it on 7275, then tab screen "information", on the bottom page changed the satellites to GPS, Glonass, Galileo, my problem disappeared.

My unit correctly shows the time now, after a start-up it is in sync within 1 second compared to atomic clock, with or without hotspot, mean also without network connection it syncs with GPS satellites the time correct.
The AGPS SUPL was using the Chinese host (supl.qxwz.com) and preferred what it looks some Chinese satellites for Glonass and Galileo and somehow the Chinese GPS time is inaccurate.

Rather Google then the Chinese that follows 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..

And now a few more!

1122 / 2211 - both popup a bubble with chinese text. I thought they were the same at first but they have different characters. (They both have the word “log” in it)

6655 - opens up a screen that appears to be the same as 555666 but these are also in Chinese so I don’t know if there are differences. Notably when you enter this menu with either code it will record a snippet of audio from the mic and play it back.

4455 - engineer mode (lots of stuff in here to explore, includes adb shell)

5544 - gps stuff

1212 - notification that says “slog copied to unkown”

2121 - seems to just take you home

45645600 - download mcu file

How did you discover the codes?

Click to expand...

Click to collapse

Just by trying a bunch of different codes and looking for patterns. Starting by looking at the codes we already knew I discovered they are all a repeating sequence of digits that are adjacent to each other on the keypad. Once you find a pattern there’s usually another code that uses the same pattern somewhere else on the keypad. If you actually type in the codes and look at the physical pattern they make you’ll see what I mean. For example 114477 is just the digits in the left column of the keypad going down. 336699 is the same pattern in the right column. And then some codes are just variations on top of that, like doing a code in reverse (which we already knew) as well as adding 00 to the end of some. This is how I discovered all the codes. Once I’d find one code Id try that same pattern in all places and variations. Simple as that! I’m sure there’s more patterns yet to be discovered so try different ideas out and see what you can find. With many people using these strategies I’m sure we can discover more! I may have even missed a few using the patterns of ones I found.
