[ROM][STABLE][Signature Spoofing/MicroG support] LineageOS 18.1 for S7 Exynos

I am asking for help or advice.

I have used LOS 16 for S7 build 30 for a longer time. Again, thanks to Ivan for this great ROM. Recently I have decided to migrate to an Android 11 ROM. However, I am struggeling with the upgrade process.
After I have flashed the most current ROM & GAPPS there is a message "Decryption unsuccessful. The password you entered is correct but your data is corrupt. ... You need to perform a factory reset. "

Background:
1) I have encrypted the phone some while ago with no problems at all.
2) I have replaced the sim card before I have flashed the new ROM.
3) I have not performed a factory resert before flashing the new ROM. I have only wiped Davlik and Cache".

Current sitatuion: When I press the button "Erase all data" a box appears with "Factory data reset. Restarting...."
This box stays for about 20 min, then I can see the Samsung S7 screen and then opens TWRP sreens for a few seconds try to run a recovery script. After this I see the same screen as explained above.

I have tried both options.
1) pressing the 3 buttons w/ power down. Screen "Decrytion unsuccesful" showing up.
2) pressing the bittons w/ power up. No reaction.

Can anybody give me an advice how to fix this problem?
try formatting data in twrp (not wiping but actually formatting)

Hi,
I installed Lineage OS but camera is totally worse than original with stock firmware. Worse quality, much longer time to turn on till I can shoot a photo etc.
Am I alone?
You'll never get Samsung camera quality with LOS as the Samsung framework is closed source.
Try Footej camera.

sometimes the smartphone freezes, mostly when i get a notification, maybe its because of notification, maybe not

only a hardreboot (3 buttons hold to restart into twrp for example) help to get it back working

did you by any chance flash magisk or something that mightve caused kernel size to change? if so please try reflashing just a rom after wiping system and cache and make sure download was not corrupt
i passed latest twrp through the official app. now I'm going back to another rom. magisk worked fine.

Is the echo problem during calls still present? I've been following the thread for some time to be aware if this was not a hindrance anymore.
(For those who have it, does it happen during any type of call? Even from chat apps?)

Why is this ROM updated if it is not usable because there is an echo on connections? So the phone does not fulfill its basic function because it is impossible to talk

I have rather few echoes. i have been using this rom for a long time and every day. it fulfills all of its basic functions.

if u want a perfect running rom, u need to stay on stock rom with its samsung owned framework.

    November security update build is up here is a brief changelog
    - Merged upstream wireguard kernel changes
    - Merged November 2021. Security update
    - Synced with LOS source
    Not too many changes in this one as you can see as i spent most of the time focusing on LOS 19 build (Android 12)
    which is coming along great (Just some gralloc work left to do and sensor hal needs some attention before first public builds)
    Big thanks to everyone who supported this project as always as its thanks to them that this project is still up and running, Enjoy new build and stay safe

    for all who have the same problem I had the same, my sim was old i just replaced it with a new one I went local office of my mobile operator for only 3 euro I got a new one sim(the same phone number of course) and I no longer have a echo problem.
    but that would not explain why the echo is not available for some with a headset.
    2
    What's your mood, can you not wait? ;)
    We have a wonderfully smooth running LOS18.1 with current security patch. A reason to be happy! (y)
    There is no need to hurry. Thanks @Ivan_Meler !

    sorry to ask but when is the "android 12 S7" ready? just want to know wait for week/month/months?

    thanks for your work!

    Take a note that a lot of LineageOS features have not been completed yet this is not a device bug and please do not report those
    in this rom thread as you will be reported to moderator also do not post bug reports for known issues or bug reports without proper
    a) Logcat
    b) proc/last_kmsg (or proc/kmsg)
    c) data/tombstones
    d) dmesg

    Also do not under any circumstances post bug reports if you are using substratum themes or unsupported magisk modules or you have performed any system modifications



    Install gapps right after installing the rom itself dont try to boot to system before that if you want to use gapps
    NikGapps and BiTgapps were both tested and working

    I do this in my free time so bear that in mind when you notice I didn't fix known bug in next available build, Currently i work on this alone and i am not one of those kangers that just copy source and claim it as their own work,
    if you want to support the project feel free to buy me some coffee paypal.me/ivanmeler




    Feel free to join telegram group with early builds progress updates and some off topic stuff Join

    Due to requests from some users I added signature spoofing support to the rom which allows usage of MicroG
    you can simply install MinMicroG and grant it needed permissions for signature spoofing to make it work as intended
