It’s good to see this is not a “partial security update”! :slight_smile:


It actually still is a partial security update, because it’s “only” the 1st of September patchlevel. This is a

But of course they have resolved the issue with the June 1, 2017 patchlevel :tada: thanks for that!


Installed without any issues.

This update came earlier than usual, already on the 13th of the month. Probably a quick update to fix Blueborne.


Great reaction time to fix Blueborne vulnerability! Many thanks!

Edit: The update doesn’t work for me. Once the phone restarts, the boot screen just shows “Error” and the phone doesn’t react to anything afterwards. After removing the battery the phone starts as usual. I’ve tried this twice.

Thanks! Was quite annoying in the past.


Update went smooth as always. Thanks to the Fairphone team!


Update this time worked flawless using the update app - unlike all other MM updates so far on my device. This time I didn’t do a backup (using TRWP w/o installation (see my post regarding 17.08.1).

So either my issue was fixed with the 17.08.1, Fairphone has solved a problem with the recognition of system partition changes with this update or @retsifp s speculation - that TWRP somehow modifies the system partition - was right.

Anyway - I’m happy with the real quick BlueBorne fix for my FP2!


Same here (except no need to remove the battery, eventually the Android error will cause a phone reboot); tried three times :frowning:

Could you go to this page and follow the instructions there.
It looks like the update needs to run again.

With this update my (normal) calls get distorted and it’s too loud in the most silent setting. This doesn’t happen when using sipgate.

The October release Fairphone OS 17.10.1 is ready :slight_smile:
