Here is the link to the guide I made on how to install Ubuntu Touch on the JingPadA1/C1
follow the link to google drive if you want to see photos on the steps. Otherwise, the basic steps are written below.

First, make sure Jing OS is flashed on the device.
Follow the online flashing tools using a windows machine

In order to accomplish this goal, I followed the process below. I'm not an expert so there could be a faster or more efficient way to accomplish it.
Once jing OS is flashed now make sure to grab the UBports installer tools from here:
https://github.com/ubports/ubports-installer/releases/tag/0.8.9-beta
I used the WIn10 version:
Ubports-installer_0.8.9-beta_win_x64.exe
Make sure to run and install the UBports Installer and have it opened and ready.
Once that is installed on your Windows machine then you need to open the bootloader menu or fastboot on the Jingpad. ( kinda like getting into the bios or UEFI on other OS’s)
You can do this from the Jingpad over a CLI just type:
sudo reboot -f recovery
When you get there, it should look like this Picture below:
Open a Chrome tab with this link: https://deadman96385.github.io/jingpad-unlock/subut/
On your windows machine and then on the Jingpad navigate to the bootloader.
It should reboot and you’ll see the JingOS logo in the middle of the screen and to the left-hand corner you see the fastboot text along with the fact that it's locked: If you try running the UBports installer without unlocking the bootloader you’ll run into this issue:
Error: fastboot:flash: Error: Flashing failed: {"error":{"code":1},"stderr":"FAILED (remote: 'Flashing Lock Flag is locked. Please unlock it first!')\rfastboot: error: Command failed"}
Once the tool sees your Jingpad in the devices, run the unlocking chrome tool. (it will say something like Android phone discovered or something like that)
At this point, you won’t be able to boot anything other than getting to the bootloader. Now the only way to get back to the bootloader is to use the manual way which is to:
Power off the tablet and then hold power wait a sec and then hold vol down until the logo comes up.
Getting it to work might take a few attempts, but don't be frustrated; it worked for me after about the fourth try.
As long as the Jingpad is still plugged into your Windows computer, run the Ubports installer, choose manually install, and look for the Jingpad A1 in the list.
(Note it might crash a few times as it did for me just keep trying it)
Follow the steps in the installer and wait.
Upon completion, it will say it is done, and you should see your Jingpad reboot. If it doesn't, you can hard reboot it again, just ensure the Ubports installer said it was done.
You should see this flash screen after the JingOS flash screen now and it does take a bit longer to boot. Just FYI
Once complete you got Ubuntu Touch installed on the JingPad. There is OTA right now but things are very much in the works. I'm still learning Ubuntu Touch, so I'm still learning. I typically use Windows, PopOS, or Debian on my computers. There is a noticeable improvement in response time and battery life, and the video doesn't lag. I'm still playing with it so I will report any major issues, but right now the only problem I've seen is that having multiple tasks running can be a bit irritating. Aside from that it's a much better experience than Jing OS.
