[ROM][7.1.x|SM-T520| Unofficial Lineage 14.1 (n2awifi)]

I have lineage-14.1-20181204-nightly-n2awifi-signed.zip OK running on my device.
If I try to install lineage-14.1-20210608-NIGHTLY-n2awifi.zip I get an error message:
Can't install this package on top of incompatible data ...
I have the impression that the installer is expecting a DATA file system F2FS. My data partition is EXT4.
Neither TWRP nor have the option to change the format to F2FS
Any suggestion?

Hello hamudistan!
Brilliant, wiping data and system in twrp before installing works!
Thank you!

Do you have any idea how to restore DATA? I have backed up the data partition but restoring on top of lineage-14.1-20210608-NIGHTLY-n2awifi.zip does not work.

Skype, Zoom, Audio does not route to speakers.

Did you ever get your audio problem sorted out???? I have the same issue. Also the same issue with Zoom.

Problem seems to be that "call audio" is not automatically routed to device speakers. But if you start a call with a headset, that works, and then you can switch manually to device speakers.

Thanks for the help!
One of the more recent updates resolved the audio routing issue. Whoever fixed that in the update, thanks!

    LineageOS is a free, community built, aftermarket firmware distribution of Android 7.1.x (Nougat), which is designed to increase performance and reliability over stock Android for your device.​

    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.

    Was just looking on the review what is in the new update or not.
    The chance on the "use our cache" seem to be near the built time, is tis all on the same server or are the timelines on par?
    Cause tis is an ineresting item to monitor to see performance wise.
    Just curious ;)

    15th build is running smooth btw!

    Use our own cache allows the lineage updater to function for official builds which i can now confirm we will be going official! It will be enabled for next weeks weekly.
    Thanks for this great ROM :)
    Can we set the updates to manual or will it check the Exynos-Team page for newer updates so we can set it to look everyday for new updates?

    Today there is a new version on.
    There should be a new nightly on every friday.
    Yes it was sorry about that and yes I am working to get n2awifi working on enforcing so it can go official for lineage please test the new 2/15 build http://download.exynos5420.com/LineageOS-14.1/n2awifi/lineage-14.1-20170215-UNOFFICIAL-n2awifi.zip
    I'll be that guy - are you guys working on 15.1 for n2awifi?

    yes - we try it ;)
