I’ve followed the exact steps on the Fairphone website on 3 separate windows pc’s to revert my FP4 back to stock from LOS 20.
I’ve made sure the drivers are installed on each one and followed the instructions fully each time.
I can find my FP4 in CMD using ADB devices and Fastboot devices but the script closes every time at the same point.
It’s asks me to type Yes to start the flash it then closes.
It’s either a duff script or Google Anti Rollback preventing flashing from A13 to A11.
I can try on Linux as the next step
Let’s hope so, there is no way to re-open the ticket and I’m not willing to start a new round of useless support communication about such an easy to fix issue, this should have been fixed 5 minutes later!
(Request #549862 if that’s needed)
@srdempster if you don’t understand the information in the topic, here’s what you need to do to get it working:
Edit: I found the link to create a follow up ticket, let’s see how long it takes this time.
I “fixed it” in the end by using a live Ubuntu and ran the script there. Ubuntu Touch is a nice OS and nearly there for me but not without the eSim support yet.
So reran the script to reset a 2nd time and sticking with LOS 20 till UT has the support. Thanks for the guidance.
Hi there - I have been reverting my fairphone 4 phone from e/OS to fairphone OS using Windows 11.
I unlocked the bootloader and I can see it says ‘unlocked’ when the phone is in fast boot. I have downloaded the latest firmware (FP4.FP4I) but I am having an issue.
I have extracted the file and then double clicked on the flash_fp4_factory and the script runs, and then it says (in yellow) that this will wipe the phone and I have to confirm by typing ‘Yes’ and hit enter. When I do this the script drops and you can’t see it any more, perhaps a crash? Looking at the phone it is still on the fast boot screen and nothing obvious is happening.
I now have one annoying issue and thats my proximity sensor has stopped working. Is there a test menu in LOS 20? I want to see if its a bug in OS, something I’ve done and can fix. I don’t really want to go back to stock to test if its working if its a bug or not.
