      I was able to install UT on a Pixel 3a with just a little angst, but it up and running successfully. The only question I have is every time I turn on the phone, it gives me the "Bootloader is unlocked warning". Is this a permanent thing?

        Congratulations! 🙂 :thumbs_up_light_skin_tone: :thumbs_up_light_skin_tone:

        YUP! 🙂

        Perfectly normal and very common on a lot of phones! 😉

        My phones :

        • BQ Aquaris E5 HD Ubuntu Phone Edition - Ubuntu Touch 16.04 LTS
        • ZUK Z2 Pro - ZUI Android 8.x
        • Xiaomi Mi 9T - Jolla SailFish 3.4.x Community Build

        P.S. : I am NOT a developer! ;)

          Yes it is. It's best to see it as a badge of honour. It means this machine has been freed from the clutches of... well, mostly Google, I suppose.

          Is currently using an Op5t
          Also owns an Op1, a BQ E4.5 and an Xperia X, as well as a BQ tablet and a Pinetab2. Please, someone... make it stop.

            FWIW I thought about a way to make the warning go away on supported devices, with the Pixel 3a being the main development target. Here is a blog post I made about it: https://fredl.me/envisioning-verified-boot-on-ubuntu-touch-devices/

            It involves telling the bootloader in a secure way that the system has not been tampered with, but has some side effects which some people might not be aware of.

              Thanks for the explanation, but please consider using a smaller font type that doesn't degrade our monitors by wasting at least 50% of the space on it 🙂

              I knew about the vbmeta.img and A/B slots stuff already but did not know that if you have all the security stuff in use that remounting the system in R/W mode is no longer an option! 🙁

              Considering how important that option is for us Ubuntu Touch users I would suggest that the developers should not waste any time on that part and just ignore it! 🙂

                @nero355 I have a security background, and to be honest, I won't just ignore it because mounting the rootfs rw is actually acting against the design decisions that went into Ubuntu Touch. I'm confident that, if this ever manages to materialize, I will make my daily-driver phone locked down like that. 🙂

                  Well...

                  I would rather have such options available at all time so no silly Google/Microsoft introduced technologies for me! 😉

                  That's also the reason that I treat all phones as toys : If they get stolen then I haven't lost any important data! 🙂

                    or someone could hack the bootloader to just not show that screen. i think there was option on the mi a2 to do this

                        @messayisto don't think that will hide the unlock screen...
