Cześć, mam S8 UIS7862s, z QF001.20230109.190922_v3.08_01, MCU: QF01.V01.71.20230103.002121

Problem z LOGO BMP

proszę pomóż :)
[Android Head-Units] isash:
you forgot to rotate the logo 90 degrees
[Android Head-Units] Aaantonn:
Hello! Please help me solve the problem.

Device S8

K706

Android 12

QF001.20220818.225855

MCU: QF01.51.20220913.002121

DSP BU32107

LXH-QF001-UIS7862S

TDA7807S

TDA7851

The problem is this: I loaded several "Agama Launcher" widgets, etc., in the widget settings I set it as the home page or the main screen, the system shows that the main application is my widget, but when I click on the home page, the widget turns off. In this case, the downloaded widgets are not displayed in the launcher selection folder, in this folder only native launchers. What can be done?

Also, there is no folder with car logos in the system at all.

There is no information about the sold firmware and the radio tape recorder, I found only your forum.

We wrote above that you need to update the firmware, where can I find the latest firmware and how to change it without breaking the radio?)

I'm attaching a video!

Hello everyone. My S8 (Osuret) hasn't arrived yet, but im curious in nature, so i collect knowledge about this unit, eg. i've read whole this thread.

I'm planning to mount it in Skoda Superb 2012. So i have some questions?

1. Is there a guide lines for rear view cam basen on canbus, which i can turn on/off in HU? I was try to ask Ossuret but they don't understand what i'm talking about :)

What i mean is shown here:

2. Is there any app for radio (no internet radio apps) where i can add a staton logo? you know, like eg. in MIB STD2

Logos for your Volkswagen or Skoda car radio

After a little fiddling over the weekend, here's a [system producing logos in the right size](https://media.info/uk/radio/data/logomaker) for your ...

media.info

3. Is there any advanced user manual? I ask ossuret but they have only basic.

As you all, i also searching a solution for fan speed control, and quality of mic.

I also ask Ossuret how to change boot animation, but they said no way to do this. Thanks to you guys, i know it is possible :)
[Android Head-Units] lefterisa3:
If you have a newer firmware than 09/01/2013 please share it on the firmware thread.

Android Auto doesn't seem to work for me, either via USB or Wireless. For anyone who has it working, what steps did you take to do it?
[Android Head-Units] lefterisa3:
I lost sleep functionality for a reason...

Tryied everything..

The code to disable and re-enable sleep.

Cycled the setting to sleep for 3 days...7 etc..

Checked the power and acc cables to ensure power is always on..

Nothing. Unit everytime left for over 5 minutes off..

Restarts.

Any other ideas?
[Android Head-Units] Clyde72:
Running the 26.11.2022 firmware I presume. Indeed fantastic news
[Android Head-Units] blue_one:
Yea i have that firmware running. 👍🏻
[Android Head-Units] Telperion:
Well this is enough for me to take the plunge I think. :D Root access goes a long way towards being able to fix any assorted issues. Do you have the Hizpo or Ossuret branded unit (or a different branding)?

Edit: I ordered the Hizpo branded S8 + dash fascia. My vehicle's AC controls integrate with the head unit, we'll see how this goes.
[Android Head-Units] blue_one:
I have the Ossurret S8 which is just the same i guess.
[Android Head-Units] kikegsxr:
Hello, I have solved my problem with the name of the stations after updating the device.

The seller sent me some update links dated December 16, I think they are more modern than the ones here.

I leave the links in case anyone he needs them.

https://jitufirmware1216.oss-eu-central-1.aliyuncs.com/update.zip

https://jitu375344745mcu1216.oss-eu-central-1.aliyuncs.com/mcu.bin

Thank you very much for this post about our unit.
[Android Head-Units] Clyde72:
Can you share a new sceenshot with your specs since the update?
[Android Head-Units] Clyde72:
It's ok, seems being a very slow connection with that server but download is still running...
[Android Head-Units] Clyde72:
Thank you very much. Looks indeed like a latest version 16.12.2022. I will maybe try this update on my unit.

It is bizarre as my Ossuret S4 unit came with 19.10.2022 version early December and my seller ask me a screenshot and then told me there wasn't a newer firmware version... but I managed to do the 26.11.2022 version update found here in the thread without any problem...
[Android Head-Units] Telperion:
With ADB, are you able to reboot into the bootloader?
[Android Head-Units] blue_one:
Not successfully yet. The bootloader is unlocked in the developer settings and the adb command reboots the unit. But than there is only a screen which says " fastboot mode"

Edit: or ist this the wanted mode already? (It been a long time since i´ve modded an Android device and i think i´ve expected the recovery screen instead.)
[Android Head-Units] Telperion:
I'm not sure what to expect from this particular bootloader. "adb reboot bootloader" would get you there, or possibly "adb reboot recovery" depending on how the device is configured.

There's no such thing as fastboot over WiFi though, so you'd need a USB connection to execute bootloader commands. After rebooting to bootloader, does it work to connect a cable? If you have a command prompt, you'd execute "fastboot devices" which would then identify your connected device if it's successfully connected.
[Android Head-Units] Clyde72:
Another issue I adressed to the seller. Earlier questions in this thread about speed dependent volume control got me looking further into it. In fact I found in the canbus settings a kind of DSP with has this AVC/SVC settings going from deactivated till level 7. Though these settings can't be altered/do not activate speed dependent volume control. Got me puzzled because via the canbus connection the unit receives speed pulse so speed depended volume control should be possible.

The seller agreed to my reasoning and replied me they would look into that so I hope they will come up with a fix/update for that. Fingers crossed.
[Android Head-Units] blue_one:
Maybe we have an alternative way which could be tested: give tasker the permission for simulating hardware keys via wireless adb. Than tasker should be able to control the volume by any rules like gps speed. The IDs for the hardware volume keys are listed somewhere.
[Android Head-Units] Clyde72:
That could be plan B. Kept me puzzling because way back I drove an VW (before canbus or whizzles & bells) and I had SVC then with an Pioneer aftermarket radio/cd. Would also like SVC/AVC now. It is a very practical feature as I recall it.
[Android Head-Units] blue_one:
I´ve made some progress on this topic. I can controll the volume keys via ADB now:

Volume up =

adb shell sendevent /dev/input/event2 1 602 1 //keydown event

adb shell sendevent /dev/input/event2 0 0 0

adb shell sendevent /dev/input/event2 1 602 0 //key up event

adb shell sendevent /dev/input/event2 0 0 0

Volume down =

adb shell sendevent /dev/input/event2 1 603 1 //keydown event

adb shell sendevent /dev/input/event2 0 0 0

adb shell sendevent /dev/input/event2 1 603 0 //key up event

adb shell sendevent /dev/input/event2 0 0 0

Next step is to give tasker the permission to handle these keys. Than it will be possible to automate the volume setting.
[Android Head-Units] Clyde72:
Thx a lot. Firstly I am a novice so I could not automate this (yet). Secondly this will have to be plan A because the seller answered me that SVC is not supported yet but they will try to implement this for future HU's. I got a thanks but no solution in short :-).

What model HU do you have? For S4 & S8 e.g. there isn't a firmware & mcu dd 20221125... See the first post 20221019 > 20221126 & 20221216 (still to test)

Can you do a reset? Their is a pinhole in the upper right corner (on my model at least)

Hello! How can I turn off the function so that after stopping the car the android stops completely and not just the screen turns off? Hizpo S5 QF001 UIS7862S Opel. Thanks!
[Android Head-Units] Aaantonn:
Hello. There are lines and they are even dynamic, they work from the steering wheel, you only need to set the brand of car and the brand of kanbus in the settings.

I have had a radio tape recorder for a week, I asked the seller about a new firmware, updated the system and the radio tape recorder began to look better! After purchase, you must update without fail! The menu has become larger, it became possible to set a logo and your own widget, and most importantly, the sound has completely changed, now at a volume level of 15, as it used to be at 30 +, the bass has become cool! I had to turn up the bass almost to minus! Now I really like the radio, but I got upset before the firmware, the sound was ****! I'll throw off the firmware in the branch firmware K706

As for cooling, I will decide something, they write here that the fan does not support the board until the age of 23, but I doubt it, maybe there is some kind of program, etc., since there is a place for the fan.
[Android Head-Units] fefferico:
Do you guys know how to pair and reset the TPMS app?

It keeps failing reading data, I'm sure it needs to be configured somehow but dunno where to start.

Thanks in advance
[Android Head-Units] Clyde72:
Go to Settings, Factory, type 15935700 and confirm. This will turn off sleep mode. To check, turn off the car & take the keys off. After 5 min or so, restart the car and check if unit fully boots.
[Android Head-Units] fefferico:
Nevermind I just found it: it's under "car app => general => reset => tire pressure calibration"

I thought "reset" was a button to reset menu voices... Not that intuitive but did the job
[Android Head-Units] Meteordust:
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 ;)
[Android Head-Units] Meteordust:
When you use that factory code is there also a way to change it back?, because in Car Setting you can also simply set sleepmode off without using any code.
[Android Head-Units] Meteordust:
No, the mainboards before production date 22-12-2022 just have a 12 volt permanent power supply, in my unit it switches off within a minute after take key out of ignition switch, but hardly hear my fan, only when engine is off very softly, even the less quality fans should run for 30000 hours or so, with average speed of 50 km/hour that are a lot of kilometers.

The "S" units have already standard a fan, you have unit without fan?
[Android Head-Units] Meteordust:
The mentioned Sunon fan by Blue_One earlier in this thread will do 60000 hours.
[Android Head-Units] Aaantonn:
I have a unit without a fan, but there is a special installation place for it S8. Aren't there any programs for the fan to work?
[Android Head-Units] Meteordust:
Where did you bought this unit, because a S8 unit should have a fan already standard fitted, that was at least on my unit, maybe they changed it, or depends if it is a universal unit or for a car brand with a front that fits in dashboard without adapters.

The fan is already discussed earlier in this thread what kind of solutions you can make, like extra temperature control board with sensor, but so far I know the plug for the fan in older pre 2023 mainboard is not controlled, only after 22-12-2022 there is a controlled fan, but what I understood an on/off around 50 degrees controller, the fan control app is also on my firmware but not doing anything.
[Android Head-Units] Winerix:
Best DSP settings? Please take a picture. Thanks
[Android Head-Units] Aaantonn:
Block with a front part, well, I think this does not matter, because it is simply inserted into it. When I bought it, I didn’t think about the fan, and I found only one seller with a fan for my car, but because of the 2K screen there is a very big difference in price, and from my own experience I know that you will hardly see the difference between 2K and 1280 on a small screen, no matter what anyone says. Plus, I was bribed by 3-day delivery with aliexpress. I even took it apart to check what's inside, everything is as described, only the board is unknown, in the google is 0 information.
[Android Head-Units] Meteordust:
You don't have production date somewhere on the mainboard ? and yes hd 720 is just fine for a small screen, videos/youtube etc are clear
[Android Head-Units] Clyde72:
If you tap the code again sleep mode is turned back on. It displays a message after confirming the code.
[Android Head-Units] Aaantonn:
I think the numbers are 20220621. Probably 22 years 6 months

[Android Head-Units] marioti:
Aaantonn thanks for answer me about guidelines of rear view camera.

I'm curious with what production date they send HU to me.

When i receive it, first thing i'm gonna disassembly it and check :) because my should be with fan and with control of fan. But of course it could be truth, same as android 12 :)

Still waiting for anyone who can, say more about my question.
[Android Head-Units] marioti:
Just curious, where to buy direct from Jitu? On alibaba they make only wholesale. But the S8 unit is cheaper ca. 90USD
[Android Head-Units] Aaantonn:
Take a chance and get an older model again))
[Android Head-Units] Aaantonn:
I had a question, after updating the system, the voice assistant crashed, and the second time the same code does not enter, it writes the code has already been used. The seller has not responded. Can this be fixed or do I need to buy a new code?

I read on one forum that this K706 system is very bad and, if possible, you don’t need to buy it, but choose another one. But honestly, after updating the system, I have no complaints and I don’t see what is wrong with it, the components are good, it works quickly. The author directly vehemently argued that it was necessary to take another, but it seems to me that this is all nonsense, it's just that the author is not competent.
[Android Head-Units] Meteordust:
Yes Alibaba, you can buy a sample..so just one...new in box. but they charge 30 dollar express costs and tax for your country on top of it....you can avoid tax when you are a company.
[Android Head-Units] Meteordust:
Indeed unit does what I want, Sygic navi, Agama car launcher, radio, music and see F1 tv pro when on the road due work 😁

Author is worried about security and want things above normal buyers of this unit, this with respect ..but for the money this unit performs very well ...
[Android Head-Units] Telperion:
Anyone? How is it supposed to work? When I connect my phone via USB, and open the Android Auto app on my phone, nothing happens on the head unit or my phone. When I pair my phone via Bluetooth to the head unit, the Android Auto app on my phone says that a wireless connection is available, but nothing happens on the head unit or my phone.

Update: My CarLetter app doesn't have the Android Auto logo like I'm seeing the "tutorial" says I should have. Update: Nevermind, I figured it out. It's very unintuitive.
[Android Head-Units] blue_one:
Thank you for your friendly and warm words. That is really motivating to help other on this forum.
[Android Head-Units] Telperion:
I decompiled one of the Launcher APK's ("Gradiant Black", it's the 4th launcher from the left). These should be fairly tweakable to modify some of the underlying functionality. Nova or another launcher is obviously an option, but I like that the built-in launchers embed Navigation on the launcher screen.

Some details: The apps for Navi, DVR, ODB, and TPMS on the embedded home screen are not hard-coded per-se, they're mapped to system props which contain the target package name.

Navi: persist.sys.maps

DVR: persist.sys.dvr.app

ODB: persist.sys.obd.app

TPMS: persist.sys.tpms.app

You can change the contents of the property (via setprop) and embed any app you want in the home screen.

For the media playback widget, it keeps track of the last audio source in "persist.sys.qf.last_audio_src", and contains one of the bluetooth media, local media, or third party media player package names. Whatever the last audio source being played was, it controls via the widget.

[Android Head-Units] Meteordust:
If your Car Letter doesn't have Android Auto logo...means your phone is not connected.

I don't use it, only tried it to see how it looked.

Normally it should automatically connect when you connect your phone with usb cable.

Nothing to be done on your phone...assume you tried in Androud Auto on phone to connect to a car, does it show nothing?, mean the blue connect button to add car, on bottum of page you also have wireless Android Auto off or on setting, you have that on or off ?

So hard to say what your problem is...cable, Android Auto on your phone, a setting?

You running latest firmware...updated Android auto on phone and HU?

You also don't see anything happening in your phone?, my phone gives notification when it tries to connect.
[Android Head-Units] Aaantonn:
Regarding the cooling of the radio, if you do not have it automatically.

I found three options:

1) Connect the fan through the amplifier wire and turn it on for the summer, turn it off for the winter. If you have an on-off button in the program. The advantage is simplicity.

2) We connect the fan through the thermostat KSD-01F 50-60 degrees. Glue the thermostat either to the processor or to the amplifier, let one of the wires go first to the thermostat, and from the thermostat to the fan. The advantage is that the thermostat is cheap, the fan works automatically without any programs, once done and forgotten forever!

3) We connect the fan through the amplifier wire, download the AutoFan application (the application is paid, it costs about $ 10)

In the application, we set the on-off temperature. The application works in the background. Plus in the ease of use, the minus is that it is not known whether the program will work on your system.

Share information if you tried to do something from the list.
[Android Head-Units] Meteordust:
I can agree now that stock fan is crap ..after a month it starts to make noise when starting the unit, like bearings without grease.

Fan is not suitable for very cold condition in my area...when car gets warmer noise disappears.

So will order the better fan also...
[Android Head-Units] Aaantonn:
I also decided to order a Sunon MC35101V1-000U-A99 12v, but I have a specific size of 35-35-10.
[Android Head-Units] Meteordust:
Well Blue One already mentioned that the Sunon will fit MF35101V21000UA99, 35x35x10, this is a low noise, but the stock fan was also low noise in my car....but fan can' t stand the cold, below zero degrees and the humidity that it is causing in the car....hope the unit can handle it better...🤔

Ordered 2, just in case...but now I need to take HU out..that will be hard...
[Android Head-Units] marioti:
This Sunon is 7500 rpm, so i just wonder, is it not to loud?. I'm just wonder to mount something bigger like 60x60mm low noise / low rpm. In my case i have to connect amp blue wire to antena separator (adapter from 2x Fakra to DIN)

The idea with KSD-01F is quite good, but as Aaantonn said, it should be glued (thermo glue) direct to processor. Maybe it'll be better to glued some kind of small radiator to processor, and the thermostat on radiator. I guess also, when selecting a thermostat, it should be check the temperature amplitude in normal use
[Android Head-Units] blue_one:
I can hear the fan if the head unit is outside the dashboard but in normal installation I can't hear it. Temperature controlled would be better ofc.
