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.
