Easy Installer "Cannot get security patch information"


I’m running the Easy Installer on a macbook air M1 to install /e/os on my Fairphone 4. The installer fails to resolve the security patch (which is July 5 of 2023 in my case).

I think maybe it is because the latest available version for Fairphone 4 (https://images.ecloud.global/stable/FP4/) is the version 1.13-s. This version is compatible with devices with security patch of June 5.

So in my case the anti-rollback security will brick my phone if I install this version. Maybe to avoid this the installer does not work ?

Also I cannot do the manual install (of version 1.14 for security patch of July 5) as it does not work on macOS.

There is a way to install /e/OS on my Fairphone 4 from my mac ?



PS: Of course my phone is unlock I already did an installation few month ago and everything worked fine.

I don’t think that’s exactly what’s happening. The installer is not able to read the version number (for whatever reason). And as it doesn’t know the version number, it can’t know if the anti-rollback feature might brick the phone, therefore it stops. The outcome is basically the same as if the version number was too low, but the fix of the issue will be different.

If you click on the “V” left of “Log” the installer will show its debug log. That should indicate where the problem is exactly. But IIRC it’s not possible to copy the log text from there (just try, maybe it has changed at some point) and nobody knows where the log file on Mac OS is located, so that one could open it with a simple text editor in order to paste its contents here.

Edit: the error message indicates that the following command didn’t succeed (and the log should contain the corresponding error message)

adb shell getprop ro.build.version.security_patch

I have the same issue. Haven’t been able to solve it.


I used the manual installation procedure instead of Easy Installer and it work.
