@Suleiman Today the installation worked fine. Maybe it's because I used another USB-cable, or because I unchecked "Wipe Userdata" and "Bootstrap" in the Installation options.

I'm so happy. Now I hope the Jingpad can work as an everyday device.

@cannonfodder Try the following. Turn off the pad completely. Once you are sure it has shut down, Hold the power button down, wait one second then hold the 'volume down button' as well until the Logo appears then release both buttons. It is all about timing. If you are too early/late with the volume button, then you have to power down again and try again.

It took me a few attempts at first. Also note the pad cannot be completely shut down if plugged into any power ie charger or computer.

What worked for me, was too boot into recovery (via buttons or command), then start the installer, select Pad manually, follow installer instructions and when the instruction is to boot into recovery, then plug the pad into the computer.
Hope this helps
Cheers

Hi @writersglen ,

@writersglen said in Ubuntu Touch on JingPad:

It’s curious that we seem to need a proprietary OS to unlock the bootloader when, as I understand, Android, the foundations of the JingPad OS, is open source. And more, when we’re striving to install an open source OS.
Is JingPad bootloader source code publicly available?
I’d be delighted to pay a bounty to anyone who can program and clearly document a totally Linux-based recipe for installing Ubuntu Source on the JingPad.

For all those who believe that we are in a digital age, I'm sorry to disappoint you. At most, we can speak of a semi-digital one, similar to the semi-automatic machines in automation. Because any interface between the digital and the human is unfortunately (or fortunately) still analog.
There would be as an example:
Screen, loudspeaker, the inner electronic, yes even the CPU works analog (many many electronic circuits in miniature size). It is only the hardware working together that allows us to have a digital world.

In order for them to work with each other, we need miniature software called drivers. Which are not "open source", and which hinder or prevent the "open source" operating system to get full access to the hardware. Unless the programmer has access to all the required "source code", both drivers and operating systems.

So hopefully it's not so strange now.

Greetings Mario 😉

@DenMoore You were right. On Windows I needed to install unisoc drivers. I followed the instructions here.

@ian
Thanks for the info. I did not know this.

@miy I had the same problem as you and I believe I posted how I resolved the bootloop in the Jing forums. But they are gone now.

It seems to me that when you want to shutdown the JingPad when it is in this state you have to hold the power button in and wait for two things to happen. 1) the familiar buzz and 2) about 10 seconds or so later you'll see something flash across the screen. This is when you release the power button.

Wait a few minutes before trying to reboot into recovery. When you do boot to recovery I find pushing the power button + 1 second then volume down and wait for the Jingpad logo then release and wait 20 seconds or so. You should have a recovery menu.

It has been a while since I had to do this and I'm working from memory. I've pretty much given up on UT on the JingPad. Good luck!!!

Will look at the links tomorrow as it is late 💤

I found a "bug"? I guess...

I'm not sure why. I have A1 version and I installed A1. Here it shows C1 and also in settings. Also when I try to make that directory, it reports "Read-only file system" although I did the remount.
