LineageOS 17.1 for Samsung S4 I9505
Can anyone please tell me if this is OK for Samsumg S4 GT-l9506?.
Also, I see things like this... 'jfltexx' referred to and can't see anything that looks like this in my phones About info., is it a model or something?
If this isn't for you model, is there an alternative that will bring it up to date.
Many thanks.

All the source code for LineageOS is available in the LineageOS Github repo. If you would like to contribute to LineageOS, please visit our Gerrit Code Review.

    What all works

    RIL (Calls, SMS, Data)

    What doesn't work
    Possibly other things that aren't listed.

    Creates a full backup of the system

    Installation Clean :

    Before you begin, save
    Remove the PIN protection and then restart for TWRP recovery.
    Erase data under Advanced (do not format data - this will erase the internal memory)
    Delete system and cache under Advanced

    Flash ROM + Gapps or nanodroid
    Optional - Flash supported root

    !!! OTA-update is like in all my Roms set up !!!

    Updates can be downloaded and installed via lineageos_updates on your mobile phone.
    if it should not be possible to install the update automatically or you want to install it manually, proceed as follows,
    (Selects in twrp) install/selects memory/internal memory/parent folder/data/lineageos_updates.
    chooses the build and installs it and everything else you want to install and restarts after that.

    to activate root navigate to Settings->About Phone and tap on build number 7 times,
    go back to System on developer options and scrolls to root access and activates it.
    to be able to boot from the power key to recovery on long press, it simply activates it in the developer options under Extended Restart.

    Download Rom

    Downlad Bootloaders with modems
    - I9505XXUHQK1_I9505XXUHQK1.tar

    Attention OP Name Has been changed all post are no longer valid. my rom has Signature Spoofing and is microg ready]
    new update

    I recommend a clean installation.
    you'll find everything else in the op.
    Unbelievable. For quite some time I haven't had a look for new ROM's. My old s4 is serving as nevigation device purely, having a broken screen. My son also had an s4, but last week charging via USB stopped working. Now I have made the two broken machines into one fine device, running Android 9!
    I installed via the LineageOS Recovery, using SD-card.
    GPS fix is quick.

    Great work. Thanks to the experts.
