I just received the Fairphone 2 with slim case. I’d like to try directly fairphone open OS. But I encountered few issues.
So, I downloaded the file from here (https://code.fairphone.com/projects/fp-osos/user/fairphone-open-source-os-downloads.html#ota) from the phone. First problem is that the download stops randomly and I can only download up to the end if I keep the notification of download open until the end.
Then, I open the file with the updater app, it reboots and then it fails installing because it cannot verify the signature of the file. Precise error is:
Finding update package... Opening update package... Verifying update package... E: Failing to verify whole-file signature E: signature verification failed Installation aborted
At the top of the screen, it’s written:
Android system recovery <3e> r4275.1_FP2_gms_1.13.0
Then I thought, maybe I should make an update of the current OS since I had a notification of the fairphone updater app. Unfortunately I don’t recall which version to which (the version above is from a try after that). Now the updater says I’m up to date with Fairphone OS 1.13.0. However, it doesn’t seem to be correct, since there is an update to 17.04 (which I thought I was going to get that one upon updating). I checked also my updater app which is not the last one (I have 1.37.1, and on play store there is a version 1.39).
Now I don’t really understand what is the problem, and how could I fix that.
I tried to download the file for open os 2 times but it didn’t change. Could it be that I did not log in with Google credential somewhere ? I think that I could download manually the FP OS 17.04 but it feels wrong doing so.
Also I don’t have sim card yet, if it matters.
Thanks in advance.
