You need the latest adb / fastboot and need the latest usb drivers for your device.
Did you use Heimdal with Windows?
I tried everything for day’s with Heimdall frontend for Windows, but was unable to get it to work.
I believe Linux has more up to date versions,
I did read, a lot of Linux distros have problems with fasboot, like ```
fastboot devices < waiting for device > and stucks at that, with different solutions.
But Heimdall on Linux seems to work.
This works perfectly, thank you

This is T Version not U. Works good, no problems. Update was easy, no recovery
Thanks to the team
My eSIM doesn’t works since U. But now I think this is because I removed the eSIM to try to reproduce someone else problem and now I have to wait for a new QR code to try reinstall. The eSIM is not mandatory to me as I normally use a physical SIM.

Still very happy with my new FP5 with pre-installed /e/OS. So far, everything’s fine, besides two minor problems with Bliss Weather:
The widget doesn’t work, it shows no weather. Initally, out of the box, it worked. I installed a different launcher (Nova) and it still worked for some time. But shortly after it stopped doing its job, just showing nothing. That happend under 2.6.3 and still is the case under 2.7
The widgets’ refresh button didn’t and does not refresh the widget but opens the settings.

Issue:
90hz mode “smooth diaplay” consistently not working after reboot/screenlock. I would like to know if this ia acknowledged as an issue as my raised gitlab issue since from a year ago is broadly ignored.

The update was OK. Everything seems OK.
Only one issue: some apps have access to the true location of the phone instead of the fake one (for example Casio Watches, Here GPS Location).
Gigaset GS290
from e-2.6.3-s to e-2.7-s
the update went normally, without recovery-mode.

The essential is working, as far as I tested.
Thank for the work of the /e/-OS-team
Update went fine.
The camera issue remains (both Fairphone and OpenCamera) that 48MP pictures are not actually 48MP but much lower resolution.
According to this it might be an API-bug.

Works very well,
Thanks!
I checked the camara pics with a FP4 running on latest Stock-OS (FOS): Also just 4000x3000px resolution.
Same device, same issue… Did someone try to push it with adb ?
FP4 users with eSIM: We had released an eSIM fix along with v2.7 …are you still facing issues with the eSIM on the FP4 even after the v2.7 update?
If yes, while sharing issue details on this thread, pl also specify your service provider name.
It was working properly on /e/OS versions before 2.6 though…
Sorry, not using an eSIM on my FP4

Update to version 2.7 official went ok.
Issue:
SPOT is a disaster. Messages like: suspended,time out, Captcha, server API error.
Is this behaviour part of the server problems?
Dear @Manoj can you please tell me of my Murena One phone will get an upgrade to Android 13 or 14. For now it is still Android 12.
Thanks for the hard work of the /e/-OS-team.
