My procedure is go into the folder, select the part0, part1 and desc.text.
Add to archive.

So what you do wrong is that you select the whole folder, you need to select the two folders part0, part 1 and desc.txt

Name it bootanimation.zip and see screenshot.

Important I have other screen like you ??
Yes, I do exactly as you write... bu my 7zip sw (x64 version, latest) doesn't show among the compression options, as first choice in the list, as your picture "0 - Nessuna" instead as first choice I have "Memorizzazione" (see my picture).

But I think it's the same...

ITA : Memorizzazione = EN: Store

edit:
I thought...
rather than using .png for the frames, better .jpg (so the final zip is "lighter" and perhaps faster OS cold boot?

Or same thing?

Hi friend,

i installed my animated boot...procedure done fine from usb1 drive etc. but after restarting the unit (and now always) the animated boot as default disappeared, and therefore after the initial boot logo fixed I have a black screen, then the unit boots (after about 6 seconds), correctly.
It therefore seems that my animated boot has not installed or anyway does not work, and instead Android shows black screen.

What could have happened?

My boot animation:
dimensions frames of 996*560 .png format

part0 with 170 frames
part1 with 1 frame

desc.txt file attached.

If you want I can upload this bootanimation.zip to you so you can test it and see if it's ok or corrupt...

edit:
is the numbering of the frames FUNDAMENTAL?
I mean...
my first frame start from "000000001.png"
while INSTEAD it MUST BE "000.png" or "001.png"?

Thank you
Most likely it was the zip file or txt file that is somehow kind of corrupted.
It also happened to me in my tests.

The only way that I found to avoid this kind of locks was to build the zip with boot animation factory and in each change I repack it again with the boot animation factory.

I also faced the need to load the standard animation (or one diferente ) and resent the test logo that I was working. Somehow the file structure was corrupted that the boot logo was not been loading .

I agree with everything you write...if you don't do it right when make a final zip, it will be corrupted afterwards.

Best way then use boot animation factory for make a final zip. (y)

So for two of us, it doesn't work with the latest FW. Any special trick to get it working? What is the brand of your phone?
I have S21
After update a soft, there is Zlink as default, i changed it in Factory menu to Carletter. The unit had reboot itself. After that i run the app an just connect with the phone.
On the phone it need to be run a data transmission, wifi, bt and localisation

Ist there a chance to initialize a USB Drive quicker after the HU was in Stand-by? I use AIMP as Media Player and a 2TB Samsung SSD. To Play audio Files i must wait about 1-2 minutes and then came the USB Symbol in the Display. It makes no difference to use a Thumb Drive or a SSD. The waiting Time ist the Same.

Also used in the past 7zip 64 bits latest version so don't know why you have different options in names?
Understand you will use boot animation factory from now.

Made jpg and png but don't see faster cold boot with jpg.
Extracted our firmware, original stock Android boot ani is made with 24 bit png files.
Both work and jpg makes it smaller in size, as long you not make a 10 Mb or bigger ani it will not really matter I think.

Mine is also S8 but I can't get wireless to work. Same setup as you, but different outcome. i.e only wired AA.
I asked the seller to activate Zlink but they refuse. Says CarLetter works. Well it does, but only wired.

Hi,
well, today I unistall 7zip,download the latest release from the official site again,install this one,and now I have identical choice options to yours!
Probably something was not ok or the version I had before was not the latest...

About png or jpg frames:

better leave png as we know (from your tests) that as default Android uses png for bootanimated. ;)

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..

Hi guys, new day new problem for me with my unit, (it’s only 2 days I have it haha)

Today my unit was very hot to touch I’ve went to the fan control app the fan was indeed working (I put it to manual always on) and the CPU was 86 C degrees .. I’ve read some post about heating issue but cannot conclude to anything.. so is my unit defective ??

Temp in car was like 22 C because of Air conditionner running . I’m on the latest firmware 0508. I didn’t pay enough attention about the idle because i was a bit late driving to work so..

This 86C temps was when using Zlink CarPlay wireless

I had a similar problem, I solved it by going back to 0304, and I stayed there. Ossuret did not provide me with anything else. I have S8 with MCU QF03.

Didn’t worked for me.. I’ve downgraded to the same version but still overheating.. what is the normal temperature of the unit ? I mean when listening to radio or using CarPlay ?

i have updated my radio to 08/05 version. Because Android auto wireless is not working on my older version. Also on the 08/05 version. Now i did a factory reset and my buttons are not working any more (Home, next track, mute, navi, radio, enz enz) on my unit. Only my volume button is working. Do you guys maby know how i can fix this.

You have to remap buttons in the settings!
Go to settings, enter 8888 then you will find a menu there where you can add functions to buttons.
I am working now but I will take pictures when I arrive home if you want.

Did you get the Wireless AA work btw?
It worked well to me before the update but now it only works wired via CarLetter. :(

thank you, I will try when i am at home!

Unfortunately, my wireless android car does not work either. It randomly stopped working on the 0414 update. That's why I updated to the 08/05 version, that didn't solve the problem either. And even after a factory reset I can't get it to work..

    I appreciate your advice, but I didn't want to dismantle the radio from the car twice to position the thermopad...the left PCBs should all be the same, so the distance between the CPU and the case is the same.
    In your case this distance was 1.3mm and you used a 1.8mm thermopad, right?

    I don't understand why then another user wrote that the distance was 3mm (with S8 radio).

    Which is the right one
    Yes, i'm sure i was talked about it here, and also Aanton measured it and if I remember it was 1,6mm gap
    Look here and his previous posts
    1
    I thought that solution was only if you have low sound capture...
    Both mic (interior and exterior) are in the same line, so if you have both, they interferr,
    1
    Thanks for the info.
    If the CPU to case gap is 1.6mm I think I will buy a 2mm thick thermopad, it should be fine too.
    What do you think?
    it depends on which thermopad you buy. the higher thermo conductivity, the pad are harder. So if you want 2mm thick, then buy no higher than 6W/mK. But IMO 1,8mm is ok.

    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

    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.

    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

    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.

    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...

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

    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?
    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 ;)
