Do you have a link to your last build? the link in google drive is not there. Thanks in advance
I forked your device tree and updated (what I believe) is the fingerprint files using LineageOS device tree as a reference. I'm compiling it now and hopefully fingerprint will work.
I can only test this on the TB-8704X but this should work on the F and N as well - not sure about the V
Update 1: Fingerprint is working I'll send a download link for those brave enough to try my release.
Update 2: Here's the link to my release: Google Drive
Update 3: The Device Themes aren't working - I try setting it to dark but it's always Light.
