That's what I love about open source: your device isn't rendered useless once someone chooses to discontinue official updates!

you should have been more careful with the installation. during setup you can choose whether you want to install the lineage recovery.

just flash twrp again.
I also flashed TWRP , and I didn't get the prompt during install to avoid lineage recovery, for me the only solution is to flash TWRP once again.

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
Had the same problems, only I've no idea if it was because of a notification, it's not exactly a freeze as much as the phone's just stuck in the lock-screen, your buttons still work, but don't do anything (when you long press power-off the phone still vibrates but no power-off), and you don't have to use 3 buttons, only 2, volume_down + power, I've already posted the last kernel log in my last message, in this thread it seems 3 people including me and you experienced this.

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?
I had this as well going from stock and found if I format all internal sd partitions and then install dm verity, if I then install this rom, then it worked.

I think you have to do it all in one session from twrp.

Dm verity file can be downloaded elsewhere on xda.

This is my hypothesis of what I did to get it working as I had tried so many things...

Edit maybe it was actually "no verity" package as per https://www.thecustomdroid.com/root-samsung-galaxy-s7-edge/

way signal is reported has changed in android so, try checking signal strenght from settings, also xposed modules in general can cause compatibility issues so no idea, as for recents there was a trick to enable old recents by setting some android go props but i wouldn't recommend that
I figured out that for bell Canada if you change in phone information (dial *#*#4636#*#*), change preferred network to lte/wcdma and it works better for calls in poor reception areas like basement etc, it swaps over to a better voice call network when you make calls in low reception then goes back to lte after.

Another progress update on Android 12 i tracked down all needed kernel commits and they include complete BPF and cgroup backports from new kernels
There are also some good news, I booted android 12 on my s10 to see if any device tree changes will be needed and there were only few changes needed to get everything working in same state as it was on android 11 so once i sort kernel out build should actually be stable, Once again no etas yet as this is quite a large backport to kernel and big thanks to everyone who got me coffe on PayPal as it really helps when fighting with kernel haha

To those of you using GCam, what version are you using? I haven't found a reliable version I'm happy with and right now that's the only reason making me think of upgrading to another phone.

Hi @Ivan_Meler, using LOS 18.1 rather happily. After echo issue solved even more happily :)

Could you do a fix for the camera issue? Camera loses functionality everytime under these scenarios:

- after approx. 10 minutes video call in whatsapp, OR
- after a few minutes of video recording (any app), OR
- after dozen pictures taken by the camera (any app)

The only solution so far is device restart. Then camera works until - see above.

This is NOT a hardware issue, I tested on two different S7 devices with (otherwise) perfectly working camera.

Thanks!

I also notice a problem with build-in camera app and flash (automatic mode).
The click noise appears after the flash disappears and a rather dark picture is stored. Also a message (open camera error id =0)
appears on the screen. If no flash is necessary (in automatic mode) everything is OK.
With Open Camera this problem didn't happend. Version 18.1-20211005

Hi I flashed this rom and I realized that I can not put the samsung apps, then the battery does not reach 100% but stops at 92%, I installed the nickgapps but every second check to activate the play store framework. Do you have any solution?

    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

    Another progress update on 12, (we are getting closer and closer)
    I figured out a way to boot 12 with current kernel with not that many updates, so expect a build hopefully next week due to my busy schedule, Build should be as functional as current 11 builds, Big thanks to everyone who supported this project as i do this in my free time and coffee keeps me up at times haha

    Hi there, im wondering why this isnt an official build yet, can someone explain? kind regards, dedoble.
    This rom will not be official because it does not meet the requirements of lineageos team and secondly lineageos does not support singnature spoofing. Unfortunately this like rom has this.
    To get it officially must be given all the requirements which unfortunately are not present. And honestly it doesn't matter if it comes from Ivan directly or via lineageos server. Ivan does a good job and you can trust this rom.

    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
