I downloaded it and tried to sideload it manually with the official instructions (https://doc.e.foundation/devices/FP4/upgrade). When I reboot to sideloa it just puts out this error though:
C:\Users\dino\Downloads>adb sideload e117t.zip
error: protocol fault (no status)
I have not unlocked my bootloader, not going to experiment with this again just to send in my phone to unbrick
Did it work for anyone?
Install files suitable for ADB sideload don’t have filenames starting with “IMG-”, as things stand currently. Edit: You can just omit the “IMG-” in the filename and try https://images.ecloud.global/stable/FP4/e-1.17-t-20231109350751-stable-FP4.zip … this is a sideloadable OTA file, at least formally when you compare the contents of the different ZIP files (I don’t have a Fairphone 4).
I see, thank you very much, I’ll try it out later today.
Was the file without the IMG you posted in the repository but somehow not displayed on the page at https://images.ecloud.global/stable/FP4/ ?
As far as I’ve seen /e/OS download pages will display only one install file format, consistent with the install documentation for a device (ideally).
/e/OS supports a lot of devices, with more than one general way to install.
In case the OTA format (which can also be used with ADB Sideload) is somehow not chosen for the official install documentation and the respective download pages for a device, OTA install files still have to come from somewhere, else a device couldn’t be OTA updated via the updater.
Over time there were some hints here and there on how to find working links to them in such cases. I just chose a possibility and tried.
Sadly I cannot sideload this file either. I guess there is a reason why they haven’t included it into the official files yet…
Edit: Am I supposed to unlock bootloader for this?
I want to upgrade my FP4 from 1.16s to 1.17t stable without unlocking the bootloader. When I enter the sideload command in adb sideload mode, I get the error: protocol fault (no status).
e/Os version: 1.16-s-20231013341147-stable-FP4
But no worries, I realize it just isn’t done yet and will wait until the stable version is announced.
I did a little research myself. The reason was the ancient adb I was using (from 2014). I actually had to delete the file and manually move the new one to my adb folder, until then Windows used the old version for some reason. Update is installing now
Thanks a lot for your help AnotherElk!
Update: Flashed your image, no errors during update. Now it boots straight to bootloader. Recovery still worked so I downgraded back to s.
…seen this while downloading " IMG-e-latest-s-FP4.zip " via easy-installer …
Your warning includes this version/way of installing /e/, right?
Is it possible to use " IMG-e-1.18-s-20231207360611-stable-FP4.zip " as further version via easy-installer?
grrrz,

(sometimes heaven sends procrastinating offers…i rather wanted to flash the FP4 yesterday, but the wheather was too fine…and now your today’s notice)
