thanks 
There are lots of file types there. Do I need them all?
boot.img
dtbo.img
recovery.img
super-empty.img
vbmeta.img
There is also a zip file. Does this contain everything?
Where are you getting that information about the supported models? I can not find it.
LineageOS Wiki - Samsung Galaxy S20 FE r8q
Ah, ok. But if you click at the top of this page where it says
âThere are multiple variants of this device. Make sure youâre viewing the right one.â
Then you get an almost identical page but for my device. Maybe this is the problem. Ronnz98âs build is for the devices that you mention, that is maybe why phone functions are not working for me?
The LineageOSmicroG site is not working at the moment. I will try to download the files later though.
The instructions you refer to do not need all the files that I listed above. They also prompt me to build LOS which I do not think I have to do.
The insstructions for the PixelOS install that Ronnz98 recommended also do not need all those files.
Can you provide me with a simple howto?
Correction & supplement: Samsung Galaxy S20 FE 5G r8q variant2
Supported models * SM-G781B + SM-G781B/DS
Install LineageOS on Samsung Galaxy S20 FE 5G
Download LOS4microG r8q works fine fo me.
for me when I try to download the zip file it goes very slowly for about a minute and then stops. Other downloads are fine.
I will try again tomorrow.
Browser change can be helpful. If youâre using VPN, try a different location.
I do not know why, but the phone seems to be working with lineageOS with microG.
Without any decent instructions I guessed my way to an install. The installation process did not work and took me to the download mode where it said that my vbmeta was not valid. From there I tried to use Odin to install the vbmeta that ronnz98 recomended above. It did not work twice, but then after a third restart it booted into LOSMicroG.
At first I still had the exclamation mark (!) in the mobile signal icon, but calling worked. After a restart everything seems normal.
I have no idea why the ronnz98 ROM at the top of this thread had working phone and sms, why the 2.7 did not and why I do have it now. If anyone can explain why to me, that would be cool.
More importantly, as my install was not at all smooth, are there any consequences? Should I try again?
If I do not hear anything, I will use the ROM as it now is and give feedback on what works or does not work here.
Thanks to everyone who helped me.
Step by step hereâŚ
As i said, several times, those instructions were not any good. 
They require you to build lineage OS yourself, which is not what I was doing. There were also other steps that i could not understand 
and broken links 
. In addition there were several file types to download that I still do not know the purpose of 
.
I get that the instructions are understandable for you guys and that there are hundreds of questions from guys like me with limited knowledge on this forum. If the ROM works out for me, i will try to write instructions of what i did, but it was many hours of trial and error over 3 months or so 
. I still do not know what I did wrong so that the current installation failed, or what I did right so that it started working on the 3rd reboot 
Yes, I was originally trying to install an experimental, unofficial ROM, which as a newb was clearly ill advised. I am grateful to you for showing me a rom that is hopefully now working for me, and for your advice on how to download it. 
However, is repeatedly posting the same link to step by step instructions without addressing the difficulties i have with them really helpful 
The official LineageOS Wiki installation guide for the Samsung Galaxy S20 FE 5G (r8q) is fine aka âgoodâ and corresponds almost word-for-word to the official /e/OS documentation installation guide for the Samsung Galaxy A52s 5G (a52sxq).
The fact that you donât understand what the individual commands mean and therefore donât know what you are doing is another matter.
On the other hand: if you were able to install LineageOS-for-microG, then you can also install any other CustomROM (PixelOS ROM, /e/OS ROM) for the Galaxy S20 FE 5G (r8q). The procedure is always the same: install vbmeta + recovery, then flash the *ROM.zip using the installed recovery via Host maschine Terminal > adb -d sideload *ROM.zip.
According to SourceForge download counter were downloaded:
1x e-2.7-u-20250204-UNOFFICIAL-r8q.zip
6x e-2.5-u-20241109-UNOFFICIAL-r8q.zip
Feedback on the functionality of the two ROMs is not available here in the /e/forum. From this it can be concluded that you are the first tester of the e-2.7-u-20250204-UNOFFICIAL-r8q.zip, and - it is quite possible that the e-2.7-u-20250204-UNOFFICIAL-r8q.zip is not functional. It wouldnât be the first time! @ronnz98 has not tested the build because he does not have the device on site. It is not for nothing that @ronnz98 writes Use it at your own risk!
Camera also working fine on LOS+microG
Update for /e/OS-U 2.8
