      @doniks You can safely apply all changes of this script - in fact they are all necessary, so dont bother with trying one by one 😉

      Ok, let me try.

      Yup, that was easy enough. Applied all changes. Rebuilt. Flashed recovery. Rebooted. Works just as well until here!

        @doniks In general if you got a working CM kernel no real kernel patches are needed except apparmor3 => But you can try stealing that as a whole subdir from a kernel that has these patches applied. Should be more like copy/paste.

          one step further. next road block. I've cloned the rootstock-ng thingy, downloaded the vivid....tar.gz, ran the rootstock thingy. It did it's thing, the tablet rebooted but is stuck at the Google logo screen. adb is not working. nothing seems to be happening. Not sure how to proceed, don't have any ideas 😞

            I realize that there is a deb image in the rc channel

            ubuntu-device-flash --verbose --server=https://system-image.ubports.com/ touch --device=deb --channel=ubuntu-touch/rc-proposed

            that installs and starts just fine. Poking around in that image, it seems to me as if the initrd is basically the same as my self built one, but the kernel config and the android system.img look quite different. Though, I still don't know what exactly to do ...

              @doniks You might want to try the google_msm kernel in ubports. It already contains the apparmor and other backports:
              https://github.com/ubports/android_kernel_google_msm/tree/ubp-5.1

              but it does not contain a reasonable kernel config for flo.

              You could also verify that the user space binaries and firmware files are being picked up get copied into the out/target/product/...../system directory.

              If none of that gets you any further - use adb while in recovery and go to /data/system-data and examine the var/log files for clues..

                    I think I'm good here:

                      At first I thought about looking into this:

                      If none of that gets you any further - use adb while in recovery and go to /data/system-data and examine the var/log files for clues..
                      But really, I think the problem with that build was that the root partition never got mounted, I'm not even sure whether much of anything of the initrd got mounted/executed

                      However, I think i must have messed up something earlier, maybe I did still end up using the old kernel config, I don't know, at some point (without having knowingly done something different) the screen came up (and adb as well). But then the display was all garbled up. I can recognize that it's trying to display the welcome screen, but the colors are all distorted, looking pink and green and it seems as if the characters shown are all way too big and don't really fit on the screen.

                      At that point, I thought, ok, lets switch to that other kernel,

                      @doniks You might want to try the google_msm kernel in ubports. It already contains the apparmor and other backports:
                      https://github.com/ubports/android_kernel_google_msm/tree/ubp-5.1

                      but it does not contain a reasonable kernel config for flo.

                      so I change the manifest to

                      <?xml version="1.0" encoding="UTF-8"?>
<manifest>
  <remote       name="cm"       fetch="http://github.com/CyanogenMod"       revision="refs/heads/cm-12.1" />
  <project       path="device/asus/deb"       name="android_device_asus_deb"       remote="cm"       revision="cm-12.1" />  
  <project       path="device/asus/flo"       name="android_device_asus_flo"       remote="cm"       revision="cm-12.1" />

  <!--
  <project       path="kernel/google/msm"       name="android_kernel_google_msm"       remote="cm"       revision="cm-12.1" />
  <remote       name="ubp"      fetch="http://github.com/ubports"      review="http://review.ubports.com"      revision="refs/heads/ubp-5.1" />
  -->

   <project       path="kernel/google/msm"       name="ubports/android_kernel_google_msm"       remote="ubp"        revision="ubp-5.1" />  
</manifest>

                      and copied the cyanogen_flo_defconfig file back. Ie, the one from cm deb repo with all the check-config adjustments. Rebuilt and

                      fastboot boot boot.img

                      but that produces the same result actually, adb comes up, screen comes up, display is all garbled up. Not sure, what's next.

                        Do you guys have a git repository of the kernel trees that Canonical had used?

                            Canonical says:

                            You can find all the needed Android specific git repositories at code-review.phablet.ubuntu.com . This is a working gerrit server with everything needed to build the Android images used by Ubuntu Touch. The reference tree in there is based on AOSP (4.4.2 specifically), so make sure your device specific repositories are compatible with AOSP at least.

                            For any Android related project at our git server, you'll find a branch named phablet-4.4.2_r1. This branch contains a static known git HEAD and the required changes needed for Ubuntu, including our custom Androidmanifest ( https://code-review.phablet.ubuntu.com/gitweb?p=aosp%2Fplatform%2Fmanifest.git;a=shortlog;h=refs%2Fheads%2Fphablet-4.4.2_r1 ).

                            This custom manifest does contain:

                              <project path="device/asus/deb" name="aosp/device/asus/deb" groups="device,flo" />
  <project path="device/asus/flo" name="aosp/device/asus/flo" groups="device,flo" />

                            And poking around on that website I see stuff where something deb related has happened:
                            https://code-review.phablet.ubuntu.com/#/q/aosp+deb,n,z

                            However,

                            • I can't find a decent overview of all the repositories there, e.g, where is kernel/google/msm (or should it be called android_kernel_google_msm?! can't find it either)
                            • I can't figure out what to change in the local manifest that I put in the directory where I did the initial checkout of ubports version (in my first post)

                                Do you know how to get an overview of the repositories there? Something like how I see an overview here: https://github.com/ubports

                                  I managed to download some sources from canonical, but in this double-digit-gigabyte-"source"-download, I seem to only have gotten a binary kernel 😛 so, I haven't gotten a lot wiser.

                                  And I can't see a "kernel" directory either:

abi  bionic  bootable  build  development  device  external  frameworks  hardware  Makefile  out  prebuilts  sdk  system  ubuntu

                                  I can fastboot boot boot.img and that comes up fine. It doesn't have a /proc/config.gz though 😞

                                  FWIW, diff tells me that

                                  • the out/target/product/deb/kernel file and
                                  • the zImage inside the boot image inside the device image in the rc-proposed channel on the ubports servers
                                    are identical according to diff.

                                    In the old image it looks like this:

                                    (these are the only two hits for mpd4)

                                    Does that give anybody a clue as to what I could do to fix this?

                                        The display is all garbled. It's not usable. The colors are off and the display scaling seems to be off - let me attach a foto:

                                        0_1498465851034_n7 garbled display.jpg

                                        I was just fishing in the dark for hints and stumbled over these log messages. I do not know whether they are related. The display is the actual problem.

                                          Finally some progress: We have fixed the system image for deb and are hoping now that it can be actually installed from our servers!
