FP2: Fairphone Open 18.10.0 (Android 7.1.2)

Hi all,

Fairphone Open 18.10.0 has been released. It is the first Fairphone Open release based on Android 7.

We apologise for any inconvenience caused by the lack of information from our side around the release of Fairphone Open 18.10.0 through the Updater last week. We have now implemented measures to prevent issues during the upgrade.


Changes from the previous Fairphone Open release (18.04.1).

Please report any (new) issues through the public bugtracker. As usual, please specify the steps to reproduce, and provide as many details as possible.

Installation procedure

Head over to code.fairphone.com and follow the instructions in the Fairphone Open 18.10.0 release post.

Edit: Fairphone Open 18.10.0 can now be installed through an intermediary update: Fairphone Open 18.04.3. This update can be obtained from any version of Fairphone Open (Android 6) through the Updater app.


One week ago, i installed OS open for FP2 (Android 6). After some days and hours of inverstigation i finally could install Googles services (via gapps). And all my apps worked fine.
Today, i recieved the update to Android 7 (Nougat) (i didn’t think to much…)…and now my google services works anymore…
I donwloaded gapps for Android 7, but know i can not install it. Any advice? I recieve an error “verification zip” (i followed the same instructions as for Android 6.

Thanks and Best,

You’ll have to update TWRP (make sure you install it on the recovery partition) and the flash OpenGAPPS again.


Hi! Thanks for your fast replay!
I downloaded the last TWARP Version Download twrp-3.2.3-0-FP2.img
I installed on the recovery partition, successfully.
But, still not able to install OpenGapps for Android 7.

Nevertheless, when i open TWARP (in recovery) it shows version 3.1.1-0…mmmm

The first reboot after installing TWRP needs to be into TWRP. If the first boot after installing is into the normal system, the old TWRP version will be restored.


Ah nice! I downloaded the 3.2.1-0 version and know it worked

Now I am confused about which version I should use.

Also, what is the correct configuration for the OpenGAPPS download now? I would guess ARM64 Android 7.0 pico, but I’m not sure.

ARM (because it was ARM before, and the hardware didn’t change) - 7.1 (because it is now Android 7.1.2) - pico is the smallest package to enable the Play Store, but you can choose any package you like.


For TWRP: one that works. IIRC the latest version should work.

For OpenGapps: ARM (not 64), Android 7.1 (not 7). The final bit (e.g Pico) depends on what you want/need.


Thanks for the fast response.
Updating TWRP and Open OS worked, but OpenGAPPS does not work even though i successfully flashed the latest version of ARM 7.1 :face_with_raised_eyebrow:

edit: Most Google Apps work, but some don’t (Mail, Maps are the most important ones).

Also, my TWRP version always resets to 3.1.1-0 even though I did follow this advice:

I’m not sure what to make of this, as you say updating TWRP worked, but the at the same time the version number doesn’t change (suggesting it didn’t work), yet you mention successfully flashing openGapps, which doesn’t work with 3.1.1 (suggesting the TWRP update did in fact work as you must be on a different version to not run into zip verification problems).

I can recommend this topic for more background on what people have done to get things working:


I updated TWRP via fastboot. Then rebooted into TWRP, it was the new version. There I successfully flashed OpenGAPPS latest version. But not all Google Apps work and when I rebooted into TWRP again, it was the old version. In the old version, flashing OpenGAPPS did not work (as expected). I did the same thing twice, same result.
I will read the linked topic and give it some time, thanks for your help!

One suggestion, you might want to use TWRP to make a backup of only your system partition before installing OpenGapps in case you want to uninstall them. In my case I just install OpenGapps to get the play store and download my paid-for apps, then restore my system partition.

Android 7 will finally be the point where I switch from a rooted FPOS to FPOOS with OpenGApps.
So, I wonder if this guide is still up to date (and this one)? The questions in this tread seem to suggest some versions and other things have changed. Which links/instructions should I follow and which ones have changed?

Thanks ahead!

The procedure to follow has changed (it’s written in the firts link you’ve given).
you should use this procedure : https://code.fairphone.com/projects/fp-osos/user/fairphone-open-source-os-installation-instructions.html

The second link in your post is to install the gapps, which is not mandatory (I use Fairphone open OS without gapps form ore than one year now), I don’t know if this part is still valid or not.

The general gist of the TWRP llooks okay, but there are some changes for FPOOS/Android7:

  • FPOOS comes with TWRP, but this version doesn’t work for installing openGapps. There is a topic about that here. Most success seems to have been had with installing a newer image from here (.img via downloads section). Pitfalls are that in TWRP the file manager browser needs to be toggled from .zip to .img, and that after installing you need to reboot directly into TWRP to avoid changes being reverted.
  • The openGapps package is still ARM, but now for Android 7.1 (obviously).

Before executing the script, cd to the directory where the script actually is.
