I managed to install plain LineageOS (noticed the microg builds only afterwards, sigh. Already done the work to get F-Droid privileged extension working, not going to re-do it now).
I would like to re-lock the bootloader to get my phone into a secure state that I can use for the next 5 Years without having to do any hackeroonies. However the phone refuses to boot into LineageOS and I have to unlock the bootloader again to fix this. Is there any known fix? If not, do you think this will be fixed at some point in the near future?
I’ve moved your post to this existing topic, relocking has been discussed before.
TL;DR: Not supported by default, you’d have to build it yourself.
You might want to consider one of the relockable options (iodéOS, CalyxOS, /e/OS, DivestOS) before you do that
That’s an argument yes. I’d like to stay as vanilla as possible. Set up once and run it for the next 5 years (already missing my FP2 Open OS )
In that case /e/ OS is probably the most long term solution, right? Is the back up solution from /e/ OS compatible with LineageOS if I ever have to switch?
Edit:
/e/ OS has microG pre installed (yay), but its own store (eh?) and I cannot get the privileged F-Droid extension to work.
Maybe we need a feature matrix of what is possible and what is not so easy with the different operating systems
With LineageOS I could use the adb Hack since I could remount the partitions with root via adb. But that does not work with /e/ OS. There are other reasons I dislike /e/ OS, so I am back at square one.
I would like to avoid rooting.
My simple goal is to get an OS that can be updated within the next few years with microG instead of google apps and working F-Droid with privileged extension. No fancy stuff. The Linux Mint equivalent as a ROM, if you know what I mean.
In that case, might I suggest Calyx: microG, privileged extension and based on AOSP, you won’t get more vanilla than that. Here’s the thread about it if you have more questions:
iodé could be an option as well, I don’t know if they include the privileged extension you’d have to ask someone who runs it:
(Side note, don’t lock your bootloader without checking fastboot flashing get_unlock_ability!!!)
iode OS looks great, the phone does complain about an unknown OS installed on boot, but everything is locked. Backup to Nextcloud is the best feature ever
I moved everything over from my old FP2.
also if @moderators want to move the latest few posts over to the iodé threead, I wouldn’t mind
Since the official build of the 26.03.2023, I have a bug with the lockscreen. Sometimes when I turn on the screen, it’s not possible to enter my pattern or to have the fingerprint working. The only thing I can do it to shutdown my smartphone and turn on again.
Unfortunately, the build of the 02.04.2023 don’t solve the issue.
Someone else have seen this issue?
Is there a way to go back to the build of the 19.03.2023 without wipe the data? There is no option in the update section of the settings menu of lineageos.
I got my Fairphone 4 just less than two months ago and only used Android 12 so far. However Android 12 has its own quirks like problems with AptX or strange issues with the “recent apps” button when using 3-button-navigation with third-party launchers. Also the mobile hotspot is at least confusing (you have to turn off WiFi first before you can use it etc.).
I installed LinageOS 20 along with the " MindTheGapps" for Android 13 and arm64. My experience so far with LineageOS 20 is much better than with the stock ROM based on Android 12. The only downside is that you need to unlock the bootloader, so you can not use Google Pay and some other apps which require a positive SafetyNet check. However I had no problems with the two banking apps I need. Both work fine despite SafetyNet will not pass.
Compared to stock Android 12 the following issues are fixed or improved (the list may not be complete, just what I noticed so far):
The stock launcher - “Trebuchet” - does not force you to have a defect Google search bar which can not be removed.
Bluetooth headsets with AptX work fine and not only AptX HD. There is no need to manually disable HD audio to get headsets working.
“Recent apps” in 3-button-navigation and third-party launchers work without disabling animations in the developer options first.
The hotspot can be enabled even with WiFi turned on and there is no confusing “5 GHz” option if that is not supported in your region anyway.
The LineageOS camera app “Aperture” does not require Google Photos as gallery app - you can also use other gallery apps like “Simple Gallery”. However Google Photos is support if installed and also Google Lense can be used if the Google app is installed.
“Material You” is fully supported - colors can be either based on the wallpaper or you can manually select a color scheme for the UI.
The clock on the lockscreen can be configured to be one line by default and not only if notifications are displayed.
The clock in the status bar can be configured to display seconds as well and can be hidden automatically when the launcher is active.
Status bar icons can be hidden or shown and you can select a different icon theme for the status bar icons as well.
The only issue I found so far: “Aperture” can only store images on the internal memory but not on the SD card. But with 128 GB or 256 GB internal memory this is usually not a big problem (all my pictures from 2016 until today are just about 30 GB, so I still have more than 70 GB free even with more than 60 additional apps installed I use on a regular basis). And you can still move photos and videos to an SD card manually if needed (or use a tool like FolderSync to automatically move files to an SD card or servers on a regular basis).
I would also like to have more customizations for the lock screen - but overall it is usable and an improvement anyway.
So far I am very happy with LineageOS 20 on my FP4.
Keep in mind: downgrading from LineageOS 20 back to the stock ROM with Android 12 will usually not work due to the Android downgrade protection! When you try to lock the bootlader you may end up with a bricked device - so LineageOS is a one way ticket as long as there is no official Android 13 version for the Fairphone 4 available.
However there are also workarounds using Magisk to get even Google Pay running and getting a positive SafetyNet test. I don’t need that and wouldn’t use a hack where I can’t be sure how long this would work, but the option exists.
No, downgrade without wipe is usually never possible, regardless which ROM you use.
I started with the first “official” build (2023-03-19) and never had that issue with the lockscreen so far. So maybe just wiping will already solve your issue. Eventhough this is a cumbersome task, but maybe because of the previous versions were not “official” the upgrade path was not tested as thoroughly and future updates will work better. I already did the upgrade von 2023-03-19 to 2023-04-02 yesterday using the integrated updater of LineageOS and had no problems at all.
I’m having the same issue on CalyxOS. just a tip: you don’t need to restart when that happens. if you have power button double press set to launch camera, doing so when the bug occurs will let you open the camera and then back out to the unlocked home screen.
As I understood, it’s mandatory to join a logcat.txt when we report a new bug.
As this bug appear sporadically and I don’t have found how to reproduce it, I don’t know when to start the log.
Because if I’m right, I have to send the adb command to start logcat before reproduce the bug, it’s correct?

you’d have to ask someone who runs it:
