Its been suggested that I need a memory dump and preloader, does anyone with one of these 8667 units have one or able to make one?

What I write is not necessary to suggest it, what matters is what is inside the software, Vendor.img is there build.prop, it is the same as for Junsun radio. Is v23 any difference between v22, I don't know, but this software is stable, nothing wrong with it. I see that there are different software here, you have to be careful what you download, the radio will get a black screen after bad software, it is salvageable. When everything works, it's better not to change anything

In theory it is salvagable but not always in practice...I have tried every single firmware out there, I have tried removing the radio fuse before every attempt, I have tried different usb drives in both slots. I have tried the correct procedure at least 200 times in the last week. I am now convinced the usb slots are just not reading and that I need to recover in a way using sp flash tool with a full memory dump(scatter file, bootloader etc) from a 8667 unit, like in this thread https://forum.xda-developers.com/t/rom-firmware-brick-recovery-for-7-android-head-unit-ac8227l-yt9217-yt9218-1-16gb.3931863/ but with an mtk8667 memory dump, but I cannot find one anywhere on the internet and even extracting the 8667.bin files does not give me a scatter file or preloader.

The seller will not help saying not their problem, and that 12 month warranty is a typing error and ebay refuses to help...looks like I will have to buy a new unit

Hi! I myself tried to dump the firmware (to easily try the updates without reinstalling the customizations) unfortunately without success.
I tried to connect with usb, but I couldn't detect anything under linux or windows. I have tested, I think, all versions of SP Flash and all drivers available on the internet. USB 4 pins, 6pins, debug ON/OFF in developpers and secrets options... No result neither ADB wired nor SP Flash detect.
I also tried to do it by ADB in wifi, I manage to connect, unfortunately impossible to have the root access to save the partitions directly. As long as we don't have root access or the possibility to install a custom recovery (twrp or others), it will be complicated to play with the firmwares easily.
I'm still sure that there must be a wired access, at least for the development tests and the factory installation. Maybe a cable connected to another terminal? Or a key combination to activate the USB debugging...?
I'll probably try to open "the beast" in a few months to see inside if I find a serial port, but for the moment I'd rather avoid opening it (it works 😅).
If you feel motivated and confident, maybe you can open yours and share some pictures of the inside?

I think im more ready to drop it off a large cliff.

    If Junsun, I posted a link. you have to know 100% that it's Junsun, otherwise it will be a brick. Download the app, throw in what processor, but even if you throw it, I'm not sure if it's Junsun. https://play.google.com/store/apps/details?id=ru.andr7e.deviceinfohw&hl=pl&gl=US
    And please note that Junsun sells it's devices with different platforms/CPU. You have to be sure you really have a 8667Q unit. Maybe you have a MTK8257.

    Еще один основной вопрос: как использовать функцию разделения экрана?
    to enable split screen, you need to open the application menu in the background by clicking on the envelope from the upper right corner, then select the desired application and drag it left or right to the edge of the screen, it will offer split. !!!Not all applications support sharing!!!

    Hi,
    I have the Junsun V1 Pro 4G+64G with the cpu JS 8667 bought on Ali for my vw tiguan.
    Cause I have issues with the radio (saving station, the frequencies changes even if I don't quit the app, and the quality is really poor..) I wanted to update my firmware.
    The seller gave me two links but the chinese have a weird way to manage their versions:
    - 8667Q军灿UI02-国外-VHD720x1280_v23_20220801
    - 8667Q军灿UI02-国外-1280x720_v22_20221029 --> v22 but date < than v23 !!
    So what is really the last one? Has someone a similar version as mine?
    Thank you for your help :)
    I have versions 8667Q军灿UI02-国外-VHD720x1280_v23_20220801, I evaluate positively. There is a quiet Google TTS voice, but this is a problem with any version software. Custom resolution better, bigger everything is on the screen, better is bigger for the car. I had the 1280x720_v23 version, the dark theme in google maps did not work, the sound was a little better. Supposedly v23 is the last version. I don't know if you don't need an antenna separator, maybe then the radio would receive better.

    Ведь кто-то делал рут на 4пда, почему тот кто-то не написал как это сделать, описал что делал, тема заглохла, почему?. Так почему я должен что-то говорить об этом, когда кто-то на 4pda это уже сделал? Ведь-то делал рут на 4пда, почему этот кто-то не написал как это кто-то сделал, тема заглохла, почему ?. Так зачем мне что-то говорить об этом, когда кто-то на 4пда это уже сделал

    After all, someone was doing root on 4pda, why didn't that someone write how to do it, described what he did, the topic died down, why ?. So why should I say something about it when someone on 4pda has already done it ? Ведь кто-то делал рут на 4пда, почему этот кто-то не написал как это сделать, опишите что делал, тема заглохла, почему ?. Так зачем мне что-то говорить об этом, когда кто-то на 4пда это уже сделал ?
    I described here the root procedure from 4 pda, the person who boasted about this does not get in touch or ignores it. Therefore, I asked here what considerations there are in this direction. If I just write a post here, then it is also ignored. From this calculation I wrote to you. No, there is no judgment.

    After testing Ossuret 9 I can conclude:
    + The radio is muted correctly with voice commands from the navigation, with Junsun UI2 does not mute the radio enough.
    + All applications work including the small navigation window, but it is too small for Waze for example.
    -It works an idea more unstable than Junsun UI2, google assistant crashes(app stop working) on first use and once system crashed and didn't reacted any clicks.
