FP2: Fairphone OS 19.05.3 release

I got the famous blue arrow “teamwin” / “Recovery Project 3.1.1-0” screen now as on the last update, i.e. the Fairphone Updater app is not working. So a .zip file (binary image) is necessary in that case to use the manual process as on the previous update.

Worth a try when in TWRP …

A little more detail in between …

Please note: This double arrow screen does NOT show any kind of button. All I can do is to press the power butten several seconds so the phone boots with the current 19.02.1 OS (this is working without any issues).

Note: I downloaded this TWRP file using the official app and I also can see it on the Total Commander (file browser app) but there is no action how to install it.

If both the “App Install Method” and the “TWRP Install” fail, there’s still the “Fastboot Install Method” … https://twrp.me/fairphone/fairphone2.html

Hi everybody! When I try to update my FP2 to 19.05.3 via the updater app the update fails and I end up in TWRP. The recovery.log says:

E3001: Package expects build fingerprint of Fairphone/FP2/FP2:7.1.2/19.02.1/gms-dc48370a:user/release-keys or Fairphone/FP2/FP2:7.1.2/19.05.3/gms-404195ba:user/release-keys; this device has Fairphone/omni_FP2/FP2:6.0.1/MOB30M/13:eng/test-keys.

However, my phone’s current OS is 7.1.2 - 19.02.1 as can be seen from the settings as well as the updater app:

The only thing I tinkered with is my recovery - I replaced the original TWRP version 3.1.1 with the newer version 3.2.3, because the older version wasn’t able to produce reasonable backups.

Does anyone have an idea what might be wrong?

Thank you in advance, Christian

This sounds like the value for TWRP itself, not for the OS.

Thank you for this idea, AnotherElk! I tried this already - it gives me the same result, unfortunately.

Any idea, why TWRP is using the TWRP fingerprint instead of the OS fingerprint for compatibility check?

What I was able to find out so far: The build fingerprint TWRP is using is the “ro.build.fingerprint” from /default.prop. The (correct) build fingerprint TWRP should use is the “ro.build.fingerprint” from /system/build.prop.

So the next question is: Why doesn’t TWRP load /system/build.prop and uses /default.prop instead?

The answer to that is ~40 posts up :wink:

While I had luck yesterday seeking & correcting this infamous fairphone bug on my daughter’s FP2, I have grabbed the /cache/fp_update_gms-404195ba.zip for whom it can help: http:dl.free.fr/qAApbVaut (dl.free DOT fr is a french equivalent of wetransfer or mega service; nothing to worry about…).

If it can help, save this file to an sdcard or usb-pendrive if you have an otg cable, mount the pendrive or the sdcard in twrp/advanced/mount then install the upgrade via this file.

by experience, your phone must have at least 3Gbytes free on it; This “fp_update” will not erase the phone; and it’s the 19.5.3

Thank you for your response RSpliet!
Unfortunately, the clue that your idea is not right is just 5 posts up :wink:. As I said, I replaced my recovery with TWRP 3.2.3. In this version the "Unable to find /system’ bug is solved. I don’t have this message in the log and I am able to mount /system manually in TWRP. I also tried to install 19.05.3 after mounting /system manually, but still no success.
Actually, in the contrary, those guys with the original TWRP 3.1.1 and the "Unable to find /system’ bug in it seem to be able to install the update smoothly in most instances.

Thank you anyway! Christian

I am a bit scared of doing the update now after skimming through this thread. Can somebody please clarify/summarise, if the update commonly causes issues (when using the updater app)? And if yes, how to avoid/fix them?

@holzfaeller15 People were having more trouble than usual after a failed update, because the files for a manual update were not available yet. However 19.05.3 has now appeared on the manual installation guide. If your update goes wrong, you can now use that guide to get it anyway.


I was a bit scared too… So I made a backup with TWRP and startet the update via the updater app. Everything went smooth and I’m on Fairphone OS 19.05.3 release now :smiley:. I’m on TWRP without ZIP signature verification. My phone is not encrypted and I don’t use xposed. During the update I saw briefly the TWRP screen and the message “unable to find partition for path ‘/system’”
Thanks to the fairphone software team for their ongoing support!


For the sake of completeness: I finally decided to try the manual update and it worked smoothly for me, too,

Same for me, thanks for the updated link in the manual update instructions.

First thanks for recognizing the TWRP issue when using the phone in encrypted mode (the known blue double arrow hanging screen issue when using the regular Fairphone updater app).

So thanks for providing fp2-gms-19.08.1-manual.zip so with my “friend” Linux (apt-get install fastboot) I successfully was able to update the OS again (I had to skip the previous update because of missing such a .zip file).

So I hope in the future that every update will be also released as such .zip file. Or even better developing an appropriate fix to get rid this double arrow TWRP screen hanging issue. :slight_smile:
