      @joshb Commiserations; I can truly say "I feel your pain"!
      The UBports installer tells me that I have to get back to the screen where I can choose the Bootloader, but despite repeated tries (~30X) to reboot back into that window to choose the bootloader, I have had no success.
      Tonight I'll try to reinstall JingOS though I have the suspicion that that is also going to not work.

        Yes the unlock message is normal on recent android devices.
        It stays at every boot even with a proper Ubuntu Touch installation.
        Search the forum and you'll see this device is not the only one having this.

          @keneda Problem is, it just keeps re-booting to that screen after a Power/VolDown reboot, or even if you just leave it alone.

          How do you get back to the screen where you select the bootloader?

            I don't know i don't own this device or any one with unlocked bootloader warning.
            Please wait for someone that know those.

              @aam42 You might be encountering the same problem I was. Make sure when you turn it off, you actually hold the power button for 15 seconds. You'll see the device start to reboot, but after 15 seconds it will abruptly shut off and stay off. After that, you should be able to get to the recovery menu by pressing the volume down button during boot as described.

                @bilb Hi there, I'm having the same issue of @AAM42, I would like to make a clear recap of the steps needed to get back to the bootloader starting from "WARNING: LOCK FLAG IS: UNLOCK, SKIP VERIFY!!" please correct me if I'm wrong (just to clarify I'm still not able to get to the bootloader it's just a summary of what I collected from internet) :

                • press the power button, the Jingpad will vibrate and reboot, keep holding and it will shut off without vibrating, it should be off for good. (wait a while to see if it will power on again and in case repeat while it stays off) :ok_button:

                • press the power button, wait a second and (keeping the power button pressed) start pressing volume down. This should bring you back to the bootloader menu. ⛔

                Unfortunately in my case doesn't work, it goes back to the warning so I guess there's something slightly wrong, please give me an hint.

                • Is it needed to keep the slate connected to the computer (with or without UBPorts running)?

                • After the reboot with the volume down, should the warning be presented again (this is what happens to me)?

                • How much time do I have to keep power button and volume down pressed in order to see the bootloader menu? Is it something immediate or requires some time holding the buttons?

                • Is there a moment in which the buttons must be released or should I keep them pressed until the menu is shown?

                • Is there any small detail that I'm missing in the procedure?

                Thanks a lot.

                  UPDATE: after a bit of hacking around and the with the hints of the Telegram group I did manage to get into the bootloader.
                  The procedure actually works, BUT the small (and most important) bit that was missing is the following:

                  After shutting off the device, turn the device on pressing and holding the power button, wait MORE or LESS one second (the trick suggested by a user in the telegram group was to say "one mississipi") press and hold the low volume button until the logo appears (will appear also the warning ignore it) then RELEASE all the buttons and WAIT! Wait kind of 20 seconds, after that the bootloader will appear. Waiting is the most important part because seems like nothing was happening instead the bootloader is actually loading. This procedure works 100%, once you understand it will be super-easy to do it again.
                  I hope this will help!

                  Cheers!

                    Does anybody know what would be keeping my windows computer from being able to detect the Jingpad while using the unlocking tool?

                      @patrick-hurd - As I remember, you need to put the JingPad into FastBoot mode (e.g. from power-off, press and hold power whilst saying "one mississippi", then press and hold volume down until logo appears and release both keys and WAIT 20-30 seconds)

                        @ndsipa_pomu Yeah, so I can use the command sudo reboot -f recovery. And that get's me into fast boot. But.. that unlock tool doesn't recognize my device.

                          @suoko it's got decent performance, I say about the same as a Pixel 4 phone so enough for basic stuff, not super powerful

                              if anyone else is wondering another person found USB drivers for Windows 10 for the Jingpad, they were from here https://www.droidwin.com/download-install-unisoc-spreadtrum-usb-drivers/

                              Try install these then the device should be recognized

                                  Last night I installed Ubuntu Touch on the JingPad C1. Thanks for all of the posts here as this install took a lot of attempts.

                                  A note: I unlocked the bootloader in Windows and ran the up-ports installer on Linux. I did not try to unlock the bootloader in Linux.

                                  Thanks again for all of the pointers. Now, on to the donations page. The best way for individuals to support free and open source software.

                                      So glad I stumbled on this! I was about to junk the Jingpad as it is the worst thing I had ever bought 😄

                                      I didn't have a windows machine (I do now, I upgraded and left the windows alone for a change, to update the bios etc.) so all of the updates I couldn't do.

                                      Will try to do this over the weekend.

                                        I there!
                                        I'm trying to install Ubuntu Touch on my JingPad (yeah, not done yet) and I'm getting this error:
                                        Error: fastboot:flash: Error: Flashing failed. This error code means that the device is locked, but I would say it is (screenshot added)
                                        And then error code 1
                                        When starting de device, it says:
                                        Lock Flag is: Unlock.
                                        I don't have the lastest version of JingOS, if needed, how can I install it?
                                        Any idea of what's happening? I'm using UBports Installer 0.95
                                        Thanks!!!

                                          I have the same problem. My device starts with the unlock message and shows the jingpad logo, vibrates and turns off again. I cannot enter the recovery mode. I tried every combination, as well es the mississippi trick. If I disconnect it from the charger it tells me I have to charge and does nothing. Literally I can't do anything 😞 Does someone has a trick how I can charge the device? Thx

                                            Greetings @el_pinguino,

                                            I would be SUPER INTERESTED in how you were able to install UT using Linux. I've tried numerous times with ZERO success.

                                            Since this guide is for Windows, I might go attempt that as I do have a Windows machine which I used to a) flash the JingOS and b) unlock the bootloader with the Chrome tool. But, I'd LOVE to do the UT install with Linux! I was unsuccessful at unlocking the bootloader in Linux ... but I did try!

                                            Thanks for any help you might be able to provide.
