How to update FP4 from e-1.14-s to e-1.15-s manually? SOLVED

Using /e/OS Troubleshooting
1

Hello @all,

I bought my Fairphone 4 from Murena round about a year ago. /e/-OS (s) has been preinstalled. So far, the OTA updates have always worked without any problems. However, after updating to e-1.14-s-20230816320616-stable-FP4, the updater no longer worked. When executed (Settings → Update), it crashes immediately.

Now there is a new version for the Fairphone 4 called IMG-e-1.15-s-20230913330639-stable-FP4.zip (https://images.ecloud.global/stable/FP4/), but I don’t know how to install this version. The updater doesn’t work and I can’t install this image via adb sideload because it’s obviously not intended for that (E: footer is wrong). I don’t want to completely reinstall the device. I prefer to keep my data. Hence I need an image suitable for sideloading, I guess. Any idea?

Regards

Hames

Update
I think I found the solution here: Update FP4 to e/OS 1.5.1-s possible? - #18 by confu

Even the download directory above doesn’t show it, it’s possible to download an image suitable for sideloading from there. Just remove the “IMG-” at the beginning of the url, i. e.
…/FP4/e-1.15-s-20230913330639-stable-FP4.zip

With this image adb sideload was sucessfull (and with e-1.15-s the updater works again).

p. s.
Marking the first message as spam (advertisement) by the community is ridiculous, only Murena has been mentioned once to explain that I didn’t install /e/ on this device by my own and Murena is a partner of the /e/ foundation.
