Hi.

Please check this link, https://we.tl/t-BfzaiKcdY0, this is our bootlogo that we place in the units that we install. We provide this service as a extension of our main activity so this is not a publicity or sales promotion, it is only a bootlogo example that I am sharing with @MauriBixio .

The details of the file are:
960 480 20
p 0 0 part0

It is a unique part file with 91 frames that continuous in a endless loop until the end of the boot time.

This unit is a fresh one, so we don't have too much to load but even in the future the logo will continue in the loop until the end of the time.

So depending of you logo you may make a endless loop with:
1280 720 30
p 0 0 part0

and will redo and redo the sequence without any stop.


One aspect.

Sometimes when editing the desc.txt with notepad I realise that the final bootanimation.zip was corrupted and was not updated with success.

I prefer to use wordpad.

In case of doubts do it in Boot Animation Factory to avoid additional bugs in your test process.

best of luck
Thank you dear friend.
I figured out how to act for custom boot animation logo.

From your video I notice that we still can't eliminate the loading bar "Phone is starting" at the end of the animation.

Next days I'll try my animated boot on the radio and after that I'll write the results here.

Anyone who changes his boot animation logo in any case write his comments and results here, especially if you find "a trick" to remove the final loading bar...

For anyone who wants to pack\unpack to add or replace files in "bootanimation.zip".

Use with PC "Winrar 3.9.0" which attach below.

This old version allows you to replace files inside an archive WITHOUT damaging or correcting it.

ONLY For Windows OS.

Note:
Possibly, for OS Win10 or Win11, assign compatibility to Windows7 and Run as System Administrator.

so, my boot animation is similar in time as yours. The bootlogo stay ca. 7sec. then there is playing a bootanimation ca. 4sec. i don't have setting the loop, so animation is stops, and wait till change to window on "your phone is starting"
So, how to make the animation in a loop?

Continuos loop:

1280 720 30
p 0 0 part0

this ONLY if you use one folder "part0"

--------

One loop (possible to use 2 or plus folder....):

1280 720 30
p 1 0 part0
ecc.......
ecc.......
ecc.......
ecc.......

Best way if you want to use animation WITH loop:
don't use many image frames, so it becomes smoother and more beautiful.
I prefer a single animation WITHOUT a loop, but obviously it takes more frames and needs to be more customized to cover all the time required to finish the boot animation.

Hi,

I made a few for myself and with my latest and the earlier ones before I have not always the blue screen with the "starting device" message, but it will always shows a blue screen, this can be 1 or 2 seconds,
1 of the approx. 10 starts it shows the starting device message on my s8 unit.

I have 108 files total, part0 72 files, part1 36 files, as web based 24bit png,

My present ani I have now:
640 320 20
p 1 0 part0
p 0 0 part1

Original boot ani in our firmware is as a 640 180 20 with a part0 and part1 with total 105 png24 files.

For me it seems that during the animation the launcher not getting started yet, but is starting after the bootanimation by the system., just an idea.
A "heavy" launcher takes more time to start, I use Agama.

Testing with longer animation can also be easily done with modifying part1.
Instead of continuous loop you can also set a loop with an amount of frames in part1.
BTW can also be done with 7zip, just zip it with compression method "store" or better use free bootani factory.

For instance:

1280 720 30
p 1 0 part0
p 120 0 part1

part1 will be then 4 seconds (120/30).

Hello,

I have this model of radio or very similar. Since everything I could find only led me to this forum, therefore, I understand that I am in the right place.

I have a problem with the microphone and it is that when you talk to people they tell me that they hear me very low and with noise. I have tried connecting an external microphone, but I have found that it continues to use the internal microphone.

Is there any way to modify the gain of the microphone in engineer mode as in other radio models?

Thanks

png frame makes the final zip file too heavy, better jpg frame.

Winrar 3.9.0 is needed if you have to add or remove files inside the .zip archive, but in any case even with 7zip I think it's possible to do it.

Theoretically, during an animated boot Android loads the file System, it is strange that it detects that this happens only after it has finished (then it would not make sense to integrate the animated boot into Android, it would only lengthen the cold boot phase).

Thanks for your reflections with live test. ;)

Got s4 today, really hard to install it.
Now there are 2 problems.

background noise is too loud also the sound.
Maybe my ear is too sensitive, cz I can hear background noise from many speaker with an internal amp.

And I have to set the amplified level to -15dB, which means 3% compared to 0dB.
Thought the sound is still too loud. Have to set the sound level at 3-5.

I don't think the car's internal amp caused that, cuz I don't think my car has internal amp.

the firmware is 230326 now, I'm going to ask if they have newer firmware.
The rest I can't complain about, the HU worth 200 Euro.

Well I my case my animation is as big/ small as the Android stock animation, I don't use a full screen resolution, only showing a spinning 3D Opel logo.

My looping part1 has 36 frames and runs smooth, spinning around.
With 1 frame you can only show a static picture and not see if unit is hanging or not :D.
Just wanted to keep it as close as the original stock animation, indeed .jpg will do fine too.

I know for 100% sure 7zip can do it, as long as you zip it with the "store" compression level option.

Theoretically yes, but see on my unit that the launcher gets started after the animation, myself not using one of the stock launchers.

My bootanimation runs for about 5 seconds, more then enough time to start the launcher you would think, if you also take the few seconds of the cold start bootlogo in account.

Howto lower app output volume on android ? I'm not familiar with BOOP, haven't stumbeld upon that yet
Depends on what phone you have, and what android version it is running.

This is Samsung specific: https://www.howtogeek.com/796399/how-to-adjust-volume-for-individual-apps-on-samsung-galaxy-phones/

Else, if it is a Xiaomi phone, or a android version that has also added the functionality, this is the way: https://www.androidauthority.com/xiaomi-miui-12-sound-assistant-1133145/

OTHERWISE - use a colume control app that supports individual strream volume settings: https://www.androidauthority.com/best-volume-control-apps-android-3101217/

What car? it definately sounds like you have a built in amplifier, else it would be extremely quiet when the speakers get ~6v at volume setting 1.

You can find the links to the firmware a few posts back to this one, up to the last one available...

HI.
my full scene\animation has 185 frames .jpg (full screen 1280*720) all placed in part0.
While in part1 I have only 1 frame #186, identical to the last present in part0, so the real animation is all in part0, and when it changes in part1 it is practically over, and it's ok for me if it becomes a static frame .
I do NOT use loops.

This my "desc.txt"
1280 720 30
p 1 0 part0
p 0 0 part1

However, I still have to install my animation on the radio, and understand if it is necessary to make changes ...

What do you think?

Well it should work.

If your animation is not using full screen, mean you have mosty a black background you can make the filesize smaller.

I'm using 640 320 20.

Probably when your part0 is finished due the 185/30, so around six seconds, it will immediately go to homescreen or loops a few times your part1 with one frame it.

I made my animation part0 longer and shorter with same results, always first see blue screen and sometimes, so not always, the message device starting.
When "device starting" is showed, the blue screen stays llittle longer active before my launcher starts, like still busy with hardware related stuff, have my two usb used for dab+ and front camera.

It seems not every start is the same, sometimes takes little longer.

But for me not really an issue, would be nice that after animation the launcher is already started but it seems that the firmware is not handling it like that.

Megane 3 2014, with the most simple radio.
Ah. IIRC Renault uses very low power radios, and therefore have speakers that respond VERY easily to current, ergo will be VERY loud with a proper amplifier that the S-class units have. Default is something like 4x20w and you are now feeding them 4x45w from the TDA7388 amplifier built into the stereo.

I highly suggest you replace the trash speakers that are stock in your renault, and that should solve every other problem aswell. Even a basic €40 kit will be a massive upgrade in sound quality, but do make sure they fit both width and depth-wise.

Do you know any working app which can be installed in ours HU, and it allow you to set the volume separately to apps. I have something like this in samsung phone, and it call Sound Assistant. But it is only for samsung devices, ant it not work in HU (i was try it). There is also something like AppVolumControler, but it is for older version of android, and it also not work for us.

Hello,

I have this model of radio or very similar. Since everything I could find only led me to this forum, therefore, I understand that I am in the right place.

I have a problem with the microphone and it is that when you talk to people they tell me that they hear me very low and with noise. I have tried connecting an external microphone, but I have found that it continues to use the internal microphone.

Is there any way to modify the gain of the microphone in engineer mode as in other radio models?

Thanks
So now that you have found the right place please go over the thread. Mic modding is discussed several times allready. Only hardware modding, gain modification wouldn't solve the hardware design flows with mic(s).

Welcome to the show.

    Hello guys,
    i am facing two troubles with S8 unit 8Gb/128Gb (Hizpo). Firmware latest from autofather.com.

    1. Fan remain on if unit wake up from sleep, even when temperature of CPU is lower than 50°C and fan app is set to automatic mode.
    This happen only when unit wakeup. Not happen if unit start from cold start.
    If i open fan app, set manual mode, then automatic mode, fan will work only when temperature reach more then 50°C.
    it is little anoying doing this everytime when unit wakeup.

    2. When unit switched to dark mode, google maps will not switch to dark mode and stay in light mode.

    Can anybody give me some advice how to fix this two issues?
    I see the same situation in my unit. Annother bug in software
    1
    In the photo you have 6/128, it is S7.
    i have the same info on label sticker but actually it is 8GB, at least every "device info app" say so
  • 5
    I am writing an answer to my question dedicated to specialists of this topic who do not know how the device works, but only write their guesses, and they confidently think that everyone is stupid!
    Changing the MCU version QF01 to the QF03 version is possible and very easy! Changing the version did not negatively affect my system in any way! The screen did not turn on from time to time and the seller himself told me to change the MCU, sent this version and told me how.
    To change the version of QF01 to QF03, you need to enter the code 774411 in the factory settings and then download a new MCU. The board version has nothing to do with the MCU ! As I understand it, there will be no more MCU 01 version
    3
    Is there any advantage of using Android Auto or CarPlay on the Android HU if all apps you need are installed on HU and the HU has its own sim car with cell service?
    In my opinion there's absolutely NO advantage to use AA/CarPlay if you have 4G SIM with good signal coverage. You only get hotter HU being moooore busy running AA/CarPlay wich will also runs slower and also draining your phone battery for no reason.

    Later Edit: Also I see no advantage to use AA/CarPlay at all on Android HU, even with phone Hotspot is better if you don't have an 4G SIM or good coverage/speed!
    3
    AA only makes sense if you have an OEM multimedia system that is not based on Android. Conversely, with these units, it is of no use, all you need is a phone hotspot (or 4G SIM) and you can use the same apps directly, without AA .

    Naturally my opinion, perhaps not shared by others.
    2
    Some features are better on Teyes than Sx.
    The CPUs are not the same, either.

    UI: they are all similar, true, but the graphics of a UI are subjective, I don't like the UIs of both Sx and Teyes, for example.

    A real IMPORTANT point for me is the display, in particular its sharpness, brightness and anti-glare, lasts the day, with direct sun.

    Well, with my S8 8GB\128GB as I have written here several times it is VERY BAD, very low brightness, during the day at 100% almost not readable what is running underneath. Anti-glare film does not exist...

    IF Teyes CC3 2K instead has a better screen, which you can see perfectly during the day, for me it would already be a great thing, even if it costs more than Sx units, but the problem...is all this true or does Teyes just want to advertise\marketing ?

    Anyone who sells advertises their product for sale even more than reality, to sell it...

    ONLY someone who has purchased and uses the latest Teyes CC3 2K units could truly say that!
    Now i'm waiting for cc3 2k, so when it comes, i'll say some more, compare to s8 unit which i use since february
    2
    I have a QF03 never had a single issue with it. Have updated to latest firmware and have done 1 mcu update (1 more available not sure if I will install)
    Of course, MANY problems also arise from poor writing of the latest firmware and MCUs released by developers.

    My advice:
    If you have the unit that works well, don't chase constantly new firmware and MCUs, leave the working one as it is.
  • 27
    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:
    specs.JPG


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

    I have the 8/128GB Version myself:
    Screenshot_20221129-085346.png


    Codes for the factory settings menu:

    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...

    Cheers

    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

    How did you discover the codes?
    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.

    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 ;)
