FP2: Blue screen at recovery mode

kkr

@NeoTheThird Thank you very much!

NeoTheThird

@kkr Ok, i don't have a new FP2 (from the latest batch) here, so i just installed latest Android 6 and the UBports Installer managed to install it just fine from that.

One thing you might also want to try: Before installation, fire up Android, open the settings, go to "About" and tap the build number 7 times. That will enable developer mode. Go to settings > developer options, enable USB debugging and bootloader unlocking. Then reboot your phone to Fastboot/Bootloader mode (hold volume down and power until the device reboots), connect it to your PC (i'm assuming you're running Linux of some sort?) and run sudo fastboot oem unlock from a terminal. Then reboot to system and try installing again using a different Micro-USB cable and a different USB socket on your computer to connect your phone to your PC.

If that fails, we will need some logs and further information, but first try the above.

NeoTheThird

If that still fails, please try to take a picture of that "blue screen", this sounds like a new phenomenon. Also, please try to reboot your device into recovery (If UBports recovery fails, reinstall android and use their recovery) by holding down volume up and power until the device reboots. Then connect it to your pc using a micro USB cable, open a terminal and type adb shell. That will open a phone terminal. Then, please run the following commands and copy their output. If it's long, paste it to paste.ubuntu.com.

cat fstab.qcom
df -h
cat /cache/system-image-upgrader.log
cat /cache/recovery/fail_log

@bastos777 (I think is @Bastos here) has posted this link [*] in the Telegram group. It seems the problem is a new memory chip.

@advocatux This seems to be exactly what I am experiencing as well. I tried the fixed recovery image that z3ntu posted there, booting into recovery with this image works on my phone (but no surprise - installing ubuntu using the lineageos recovery image does not work).

@NeoTheThird Yes I am using linux, I will try this.

@kkr good luck!

@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...

kkr

@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

2.) File system
~ # df -h

3.) cat /cache/system-image-upgrader.log
~ # cat /cache/system-image-upgrader.log

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?

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)

kkr

@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.

Pierre

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.

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

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....

jaapjansma

@twinkybot yes that looks like the same problem to me.
