        @NeoTheThird: Just to let you know, I`m still working to get you the logs. Even with the original android recovery my system does not see the usb device (therefore the adb shell cannot find the device). But I did not give up yet...
        @advocatux Thanks!

          No pressure 😉

          Did you unlock adb? Try opening the settings in android, go to "About" and tap the build number 7 times. That will enable developer mode. Go to settings > developer options and enable USB debugging. I'm not sure if that unlocks recovery as well, though...

            @NeoTheThird Yes I did, this does not seem to imply recovery mode. I seems like abd must be enabled persistently in build.prop. I was able to get some logs this way but the content was not satisfying so I tried again to install ubuntu. After doing so, i pushed the current LineageOS recovery image (the one z3ntu published in https://forum.fairphone.com/t/flashing-lineageos-is-not-working/31584).

            Finally, here are the logs
            The logs you wanted:
            1.) cat fstab.qcom:
            There is no such file as fstab.qcom. Instead, there are fstab.ranchu and fstab.goldfish
            They contain the following:

            ~ # cat fstab.goldfish
            # Android fstab file.
            #<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
            # The filesystem that contains the filesystem checker binary (typically /system) cannot
            # specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
            /dev/block/mtdblock0 /system ext4 ro,barrier=1 wait
            /dev/block/mtdblock1 /data ext4 noatime,nosuid,nodev,barrier=1,nomblk_io_submit wait,check
            /dev/block/mtdblock2 /cache ext4 noatime,nosuid,nodev wait,check
            /devices/platform/goldfish_mmc.0* auto auto defaults voldmanaged=sdcard:auto,noemulatedsd

            ~ # cat fstab.goldfish
            # Android fstab file.
            #<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
            # The filesystem that contains the filesystem checker binary (typically /system) cannot
            # specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK
            /dev/block/mtdblock0 /system ext4 ro,barrier=1 wait
            /dev/block/mtdblock1 /data ext4 noatime,nosuid,nodev,barrier=1,nomblk_io_submit wait,check
            /dev/block/mtdblock2 /cache ext4 noatime,nosuid,nodev wait,check
            /devices/platform/goldfish_mmc.0* auto auto defaults voldmanaged=sdcard:auto,noemulatedsd

            2.) File system
            ~ # df -h
            Filesystem Size Used Available Use% Mounted on
            tmpfs 923.1M 20.0K 923.1M 0% /dev
            tmpfs 923.1M 16.0K 923.1M 0% /tmp
            /dev/block/mmcblk0p15
            629.5M 10.4M 619.1M 2% /cache
            /dev/block/mmcblk0p20
            25.5G 1.7G 22.5G 7% /data
            /dev/block/mmcblk0p13
            2.0G 32.0M 1.9G 2% /system
            ~ #

            3.) cat /cache/system-image-upgrader.log
            ~ # cat /cache/system-image-upgrader.log
            Starting image Upgrade pre
            Processing the command file
            Done upgrading: Sun Jan 4 23:02:13 GMT 1970
            tune2fs 1.42.9 (28-Dec-2013)
            Setting reserved blocks percentage to 5% (339916 blocks)

            4.) cat /cache/recovery/fail_log
            There is no fail log. See below what`s there:

            /cache # ls -a
            . lost+found system-image-upgrader.log
            .. recovery test.log

              Update: I tried to do the steps from the magic-device-tool manually. Using the lineageos recovery image I was at least able to push the .tar.xz files with ubuntu-device-flash to the cache folder. But ubuntu-device-flash does not continue after pushing the files without giving any comment. Adding -v does not change the output.
              Does anyone have any ideas how to continue?
              Regards

                kkr, I have the exact same problem as you. I can add to what you already said that the blue screen state lets you hear the sounds of ubuntu touch os (low battery)

                  @simon Well, then at least its not the fault of my phone! Your comment about the sound is interesting because mine does not produce any sounds at all.

                    Hello,

                    I confirm this is not specific to your phone @kkr. I experience the same behavior as you do.
                    My FP2 is also brand new (part of the delayed batch).

                    Unlike you @simon, I cannot hear any sound when booting in recovery mode and seeing the blue screen.

                    I can provide additional logs if needed, but even though I am proficient with GNU/Linux system, my knowledge of android tools is quite basic. I'd appreciate if you could detail the commands I need to run in case more logs are required.
                    Regards.

                      Hello,
                      I can confirm that I have the same problem on a brand new fairphone 2. I flashed ubuntu on it but it has a completly blue screen. I can see my phone when I connect it to my computer.

                      I also dont hear a sound.

                      I found this (https://code.fairphone.com/projects/fp-osos/user/fairphone-open-source-os-installation-instructions.html#method-2-using-fastboot) tutorial to install Fairphone Os again and I am trying to do that now.

                      Jaap

                        @NeoTheThird Neo, do you have any news or do you need anything else from us?
                        Best regards,

                          Is this now related to https://github.com/ubports/ubports-touch/issues/253?

                          Do I understand this correct, that if I even have an old FP2 with a new screen that it will show the blue screen?
                          If so damn. I could not use UT because my left side of the display was not working. So no menu 😄
                          No I am waiting for my new Display and wanted to install UT now but then....
