Tried this, they are marked as H815 and return error 7
You need to remove the assert line in the rom located in:
/META-INF/com/Google/Android/updater-script. Remove all text above where you see the first "ui_print" in the text file and you shouldn't get an error anymore. The reason for this is because you are flashing a rom for another model (which is fine in this case) and it is trying to prevent you from installing the wrong software and bricking your phone (which in this case it will not). :good:

I get "Bluescreens" since some weeks. Anybody else? Maybe it's a Problem with my Smartphone or some Apps.

    LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1 (Nougat), which is designed to increase performance and reliability over stock Android for your device.​
    #include <std_disclaimer.h>
     * Your warranty is now void.
     * We are not responsible for bricked devices, dead SD cards,
     * thermonuclear war, or you getting fired because the alarm app failed. Please
     * do some research if you have any concerns about features included in this ROM
     * before flashing it! YOU are choosing to make these modifications, and if
     * you point the finger at us for messing up your device, we will laugh at you.
    LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. You will need to provide your own Google Applications package (gapps). LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

    All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

    What's not working ?
    encryption (who use that )
    f2fs (who use that too )
    QHD video recording

    official = signed
    unofficial = no signed
    to go to unofficial to official flash experimental first (and boot it)

    If you don't have a sim card detected try that
    adb root
    adb shell rm /data/user_de/0/com.android.providers.telephony/databases/telephony.db 
    adb shell rm /data/user_de/0/com.android.providers.telephony/databases/mmssms.db 
    adb reboot

    - autofocus fix
    - torch fix
    - sdcard selinux fix
    - multithread decode bootanimation
    This one is using old marshmallow sources, try my unofficial ;)

    No they are not any. Bear in mind that there are only three developers for LG G4 if I count myself in.
    Building Oreo will be a huge amount of work that is now beyond us. We are now trying to make Nougat bug free.
    No it's not beyond us.
    We will get Oreo because I'll make it happen.
    I'll merge Google source code and fix conflicts until it's built.

    The problem is time and yes ok , people too. If we were more , it would happen sooner
