This TWRP recovery uses Lineage partition layout that differs from other recoveries.
Do not mix up efs/modem/apnhlos... backups with other releases.

All ROMs/Recoveries are compiled with latest LOS16 sources/toolchain.

BUGS:
No Sound (WIP - needs proper ASOC driver)
Probably the same as 15.1

@DualJoe
The rom works well but there is no sound.
What setting can I activate to fix this?
Thanks

Hi @carlos974! How did you manage it? On my A300FU there is still no Sound without headphones. Thumbnails is the same as yours.
Sorry, that was a temporal error! This request ist irrelevant!

The function of the speaker icon on the phone is meant to be to let other people participate in the conversation or to work while speaking (for example ). But if i tap on it, i cannot here anything anymore. The sound is not redirected to the speaker. Consequently I can only hear the conversation partner, if do not tap and keep the phone on my ear.

The driver for the speaker/amplifier is missing so it's not working at all atm. I will fix it asap.
But good to know that the phone function is otherwise working properly. Thanks for reporting.

OEM unlock required?
Hello! I'm just about to flash my Dad's A3FU with Lineageos 16 (which I use on my own phone), but something is unclear to me: there is no OEM unlock option in the dev menu. Does it means that I should not worry about it and I can simply flash anything I want (with heimdall, manually compiled because Debian's precompiled version seems to have a bug that prevents it from connecting to the phone)?
Thanks a lot!
Mathias
PS: by the way, any news on the sound routing issue for the speaker phone?

My A3FU hasn't got a OEM-unlock option, too (maybe it is like this in general). Never mind, just confirm "USB-Debugging". That's enough! (At least it was with me like that).
Make sure you've downloaded the OS from the link above!

I had no OEM unlock option either and just flashed LOS without problems. That's the only thing i can tell about this.

Regarding the sound problem: The Samsung sound driver implementation is horribly outdated and doesn't work properly anymore (just affects the external speaker on the backside). The userspace part is closed source and there seems to be some kind of race condition or timing problem. What people have done on other devices with same hardware is they patched the 'mute' function (or something similar) in the closed source HAL blobs so the speaker is always on. That leads to several side effects like the speaker is always-on as well when calling and similar. It's a dirty hack and unfortunately the only thing we have currently. I do not really like that. Instead i'm going to overhaul the kernel driver. I have the new codec driver running already. The next part is to glue it all together and bring it to userspace.

A3FU doesn't have locked bootloader at all.. so no OEM unlock option needed

Jesus, even OP doesn't know that... wasted..
Good luck

P.S.: but it will trigger knox count (aka warranty from 2015 ) - useless these days
