        Dear @doniks,

        I'm considering buying "Nexus 7 2013 cellular (deb)" and as you pointed out in many threads i found, there are problems with installation. But I'm not sure, what informations are current and how to install it on the device.

        Would you be please so kind to share some sum up of "what works and what doesn't" and "how to install Utouch manually" on the device ? You seem to know about the issue a lot. Thank you.

        Pavel

        Hey @zlamalp , I haven't tried again lately, but I'm pretty sure the "deb situation" is still the same.

        That means, the files necessary to install are on the server, however the installer somehow doesn't put them correctly onto the device. This means for installation you do need to break out the commandline and mess around. I don't think that there is a risk to permanently damage your device. At some point in between, yes you might run into a situation that it doesn't start anymore, but that is fixable.

        With respect to what's not working

        • installer as mentioned, and I think this includes OTA updates. So, you might have to do some commandline dance anytime you want an uptodate version.
        • bluetooth doesn't work. I assume that this is fixable, but probably needs a recompiled kernel

        Now, for actual cellular functionality ... I just cannot remember ... it's been so long that I haven't had a sim card for this thing. I actually assume that it works, because I think I would remember if it was broken ... but, again it's been years that I had a sim card inside. I actually wanted to reflash and try it, but I'm just not getting around to do it. I'm 95% sure it works. @zubozrout do you know?

        Everything else, I'd say "just works"

        With respect to continued support from ubports, that's always a tough question. Remember it's largely a volunteer run project. Resources are limited. That said, I don't see any reason why the support for deb should get worse.

        Hth, doniks

          @doniks Yeah, LTE and everything else did work for me back when I was using http://system-image.tasemnice.eu/ubuntu-touch (currently dead) repository - which was based on the original Canonical images.

          The last time I had my "deb" in my hands (before I gave it away) I was trying to install Ubports on it after that original repo died and I can see that I was not able to make bluetooth and camera to work but I was hacking things on top of what was available so I guess that was the issue: https://forums.ubports.com/topic/44/installing-ubuntu-on-nexus-7-2013-deb-lte 🙂

          But ... even with these workarounds LTE did work for me 🙂 ... it was just a matter of having a correct "boot.img" flashed AFAIK.

          Btw, it seems pretty much everything worked for you at some point as well, including Bluetooth:

            Not sure if you can confirm camera working as well (?).

            Great! Thanks @zubozrout for the quick response and confirmation that LTE worked.

            I'm 95% sure that the boot.img (kernel) on the ubports system image server is that very file that originated from tasemnice, so all that knowledge is still relevant.

            Camera - good point. Another thing I barely use ... come to think of it, I might have actually not ever tried taking a picture with UT on deb. So, can't say.

            Ok, let me try turning around and listing some things that I CAN remember worked: touchscreen, sound, wifi, rotation, gps, usb file transfer, libertine, desktop mode and generally everything to do with system UI and apps, app updates.

              Hi @zubozrout and @doniks,

              so to put it together I should:

              • Get Ubuntu 16.04
              • Install required packages so following commands are available
              • Run following commands
              ubuntu-device-flash touch --channel=ubuntu-touch/stable/ubuntu --device=flo --bootstrap
              # Reboot into bootloader
              fastboot flash -w boot boot.img
              fastboot flash -w recovery recovery.img
              # Boot into recovery
              ubuntu-device-flash --server http://system-image.ubports.com touch --channel ubuntu-touch/rc-proposed
              

              But I'm not sure which channels etc. to use. I believe something like this would be more appropriate:

              ubuntu-device-flash --server http://system-image.ubports.com touch --channel ubuntu-touch/stable --device=deb
              fastboot flash -w boot boot.img
              fastboot flash -w recovery recovery.img
              

              NOTE: boot.img and recovery.img should be taken from the @zubozrout G-Drive: https://drive.google.com/file/d/0B_T_rjYvwUdgQ3RJMHhSLWVvY0E/view?usp=sharing

                @zlamalp no, that doesn't sound right. A UT installation consists normally of the following four pieces

                1. boot image
                2. recovery
                3. system image (device independent)
                4. android container

                the steps you propose do nothing to get the deb android container. here are the steps I used: https://github.com/ubports/ubuntu-touch/issues/643 in Workaround.

                Some more nitpicking:

                • I'm not sure in which version of Ubuntu the ubuntu-device-flash tool is available. I painfully realized that at some point it wasn't available in my version (probably 18.04). This might have been resolved, but good to check
                • It makes no sense to use --server one time, but not the other. Either your version of ubuntu-device-flash always goes to Ubports server by default, then you're good. Or it never goes there by default, then you always need to specify
                • wrt channel - if you don't know which one you want, then you want stable

                  The tool is available in 16.04 in the Ubuntu archives, and there is a build for 18.04 in the ubports repository (https://repo.ubports.com/) which can be used.

                    @dobey I thought that u-d-f doesn't work on 18.04, I couldn't install it, any particular package to install? Could you clarify what build to use, as I can't find any. Thanks.

                      Actually, after reading your post again I realize ... if this command works, you should be done.

                          The latest ubuntu-device-flash package for your architecture from https://repo.ubports.com/pool/bionic/main/g/goget-ubuntu-touch/ should work on 18.04.

                            @dobey I tried to install, it says installing,but won't install. Really strange. It's normal .deb amd64 package and it just won't work. Never mind, my wife is on 16.04, so I just keep flashing it on her laptop. Thanks for the help anyway.

                              @stefano Probably the best to add the repo to your system and use it from there. Did you try that?

                              echo "deb http://repo.ubports.com/ bionic main" | sudo tee /etc/apt/sources.list.d/ubports.list
                              wget http://repo.ubports.com/keyring.gpg -O - | sudo apt-key add -
                              

                              and then

                              apt update
                              apt install ubuntu-device-flash

                                  @zubozrout @dobey I found this and managed to install it. I know it's for 14.04, but somehow it work, don't really know what I've done. I played with aptitude and get the public.key from ubports, it still said that click-ubuntu-policy is missing and has no installable candidate. Anyway, now it just successfully flashed my Pro5 with latest Stable release. I'm over the moon 🙂
                                  this is what I've done;

                                      sorry, I wasn't able to get one. Everybody is selling older model with Tegra chip.
