Thank you very much for your reply. I think it's worth trying. All in all if things go wrong and I need to completely flash the system, this is exactly what I need to do to update it.

Has anyone been able to ADB into the Joying w/ either a USB cable or via wi-fi?
I have the cable attached to the OTG labeled insert on the back of the Joying.
I plug the cable into my computer and it does not see the Joying.
I went into developer mode and changed usb to file sharing. Nothing changed.
I searched for usb networking debug to try to adb via wi-fi but it seems joying has hidden this ability.

Use https://forum.xda-developers.com/t/android-settings-shortcuts.4336131/ to go to original Android settings. Haven't tried ADB though but should work.
Hi everyone new to the forum, hoping someone can help me but I doubt it because I have messed up big time.
I have a joying uis7862 4gb 64gb android 10 unit, the touch screen became unresponsive so I purchased a second had unit with a working screen but faulty unit. I flashed a new screen resolution as mentioned in post #462
Thank you

But now I have a black screen, the unit lights up but I can't see nothing or do anything. I have tried reverting back to original firmware with no luck, hooked unit up to a pc with usb but the pc is not picking it up, I also tried the USB out to hdmi with no luck either. Is there anyway I could get it working again?any help will be much appreciated please?
Thank you

Can anybody summarize the latest state of rooting this device with the latest Joying firmware? I'm a total boomer with searching posts on here, I can't find a recent mention. Can somebody point me at the latest rooted firmware? Or, if it's possible to use some sort of universal root with the latest firmware, that would be awesome too.
The only reason I need root is to be able to resize my screen to fit small bezels in my car. If that's achievable without root, that would be awesome to hear about too!

Thank you!
Forgive me, I get turned around with kernel vs firmware. This is an all in one solution? With a unit straight from the factory, all I need to do is flash MD Edition?
Finally, ca you point me toward instructions for how to flash a 7862 FYT unit?

11EDIT: XDA didn't like me attaching the photos, just got broken links so I'm sorry that they're embedded like this.
Joying just sent me a review unit of their new 10.1" Android 10 head unit so I figured it should have its own thread. It looks like they're pumping out updated versions of all their previous devices by the day so I imagine they'll have versions of this in all the different screen sizes soon. First impression is good. The interface is appreciably more responsive than the Intel unit I currently have in the car. I'm working on some videos but figured I'd throw some pictures in here. Here is an unboxing and interface tour video: https://youtu.be/h__Zc0fwOtw
The PCB looks is clearly iterative but looks to have some significant redesigns, especially with the power supply which is much larger than on the previous Intel design, through that might be required for extra derived voltages for the new UIS7862 SoC.
The previous Intel PCB used an STM32 MCU in between the main SoC and the bluetooth module which probably contributed to the difficulty interfacing Bluetooth devices that weren't specifically allowed by Joying. The area where this chip was now looks to be filled with power components though the same Bluetooth module is still used. I'm hopeful that this means there's direct communication from the SoC to the BT module, but that'll take more digging to determine. There is also a new general purpose ARM Cortex-M4 MCU added between the SoC carrier board and the DSP chip (GigaDevice GD32F330R8T6). I'm curious if that's taken the place of the old STM32 chip or if it's used for something else. Hopefully I'll be able to determine what it's used for, but I'm not touching anything until I get it installed and reviewed.
The green PCB is the Intel board and the yellowish one is the new Android 10 board. Of note is the fact that the new PCB has Joying's name silk screened onto it where the old Intel one didn't. So, at bare minimum, this board is spun just for Joying, even if the only differences are the silk screen layers.
Any requests for specific details?
4For those who were discussing the extension cable or mounting the screen away from the head unit:
I did this recently with this model.
The cable is not a standard IDE cable. I can't remember the correct description but I will try to send my mind back to the80s.
It is a 40 pin reversed (or flipped) flat ribbon cable using standard IDC 2mm pitch connectors.
What this means is: Pin 1 = Pin 40, Pin 3 = Pin 38 etc...
A standard IDE connector (AFAIR) is a straight cable, meaning Pin 1 = Pin 1 and Pin 40 = Pin 40
This type of cable is used for many other applications in electronics, so it's not like they made a proprietary cable.
I did an unboxing of the 10.1 unit here:And a "remote screen" install here:
And here is a photo of the actual cable that came with the unit to show the connectors, registration keys, and pin outs (Note the red/pink stripe)
I hope it saves someone from blowing up their screen!
p.s. I could be mistaken, trying to find the exact pinout for an IDE cable seems to be a bit difficult. Please feel free to correct me if wrong, but link to the source rather than just your opinion so we can all learn.

hi, I did succeed enabling dark theme in google maps. you need to set your screen DPI lower (like a phone DPI instead of a tablet DPI) before opening google maps, this way you'll trigger google maps "Theme" feature in its settings. After that, you can revert back to the default tablet DPI.
To change the screen DPI, go to developer options (enter password, I think "3368")
Scroll down until you find "Smallest width", change it to 411 dp.
Then open google maps, and you'll get the "Themes" feature
[[ Memorize the default DPI to revert back later ]]
if you want to enable "System-wide dark theme" on whole android 10. you need ADB & usb cable. I used this app "
Automatic Dark Theme for Android 10" from playstore

Thank you very much! I made a video because I think the method you think is very beneficial to those who own other models.to get ADB on UIS7862 unit, read @gottahavit reply, thanks to him

4I've decided to release CC3 to the public. Have fun. Manufacturer ID is set to 43. I am not responsible if you brick your unit or it explodes. I will provide 0 support. Do not PM me. Do not flash unless you know what you're doing or have a recovery update package to revert back to stock.
