The actual issue will be seen behind the Error message; can you open recovery when you see the Android robot, and check what it says?
hi Rick
I can not open recovery when I see the Android robot.
I tried with Volume Up and Vo Down.
Cheers
To open recovery mode, you need to press the Power button and the Volume up button.
When I press the Power button and the Volume up button, the only thing, which happens is the Android robot appears again after short buzzing.
You have to press and hold the power button, then the volume up.
I could manage:
E: Error in /cache/fp_update_FP2-gms-17.06.4.zip
(Status 7)
Just to be sure, you actually press the power button and the volume up once you see the resting robot right? Not when the phone is off.
I could manage:
E: Error in /cache/fp_update_FP2-gms-17.06.4.zip

Is that all you see? It might be your download got corrupted, just clear the data of the Updater app and try again. If you remain having issues, just install it manually.
Ok, that’s clear, it means you altered the partition before (in this case the boot partition), by rooting the device, etc. Please note that installing these updates only work on original partitions, not when you alter them. The solution for you is to flash the latest image: https://support.fairphone.com/hc/en-us/articles/213290023-Fairphone-OS-downloads-for-Fairphone-2 (use the latest binary image at the bottom of the page).

That did NOT work.
And flashed [Binary image] Fairphone OS 17.06.4 (Android 6.0) (~650MB) with flash-for-windows.bat.
I am now o 17.06.4.
Do you think the structure of partitios is corrected now?
It has been five days since the update was sent off into the wild. 
I would like to know if anyone with Fairphone OS 17.06.4 (not Open OS) has experienced any issues regarding battery lifetime and/or higher temperature. Can anyone confirm one or even both of these situations?
The binary image found on that page is the same binary image found on the page I’ve linked to in my previous post.
If you flashed 17.06.4 correctly with the provided script it should be fine; you can install future partials without any issues, that is, if you don’t mess around with the original partitions in the meantime

Still at 17.06.03, battery life is the same as before but my FP2 tends to get quite hot when viewing YouTube.
Will install 04 now and see if it changes.
Yep, battery life considerably worse, and jumps down on minimal usage of for e.g. browser usage. It did seem to run very hot using google maps yesterday. Usage comes up as majority wifi, so I’ve just incorporated the steps from Tom’s guide. Will see if it improves matters. I’d previously been happy with the improvement in battery life with 6.0, however this is back to disappointing due to having to nurse the phone when out and about…

Just noticed mine says 1 May 2017 as well. Was your question ever answered?
The Security patch wasn’t quite complete (as it didn’t incorporate all the released fixes). It is hope the next update will bring us up to date fully
