Lineage OS 15.1 fingerprint service not installed

[sk8avp]

Hello all the people out there.
Im new in the forum and english is not my mother language so, please be kind.

Hardware:
Moto G5 cedric (XT1060)

Situation:
Installed twrp-3.2.1-0-cedric.img without problems
Installed lineage-15.1-20180415-UNOFFICIAL-cedric.zip without problems
Installed open_gapps-arm64-8.1-aroma-20181116.zip without problems

Problem:
When the phone inits, the fingerprint sensor does nothing at all.
When i go to Security > Screen lock the fingerprint option doesnt exists at all. Exploring the coms (Apps > All Apps) i dont see the fingerprint service installed.
I have installed the "Ampare Fingerprint test" app and when run only says "Native Fingerprint API not found!".

Thing done:
Flash all again (TWRP + Lineage 15.1 + gapps) and the situation is the same.

Anyone have an idea and can guide me?

Did you flash stock 8.1 before?

Hi Andrej_SK, thanks for your reply.
This phone was never flashed.
I had the stock version and it was updated with Android Oreo 8.1, which was updated a few weeks ago.

If you installed stock Oreo 8.1 using any method (OTA, Fastboot...), you have to downgrade to stock Nougat first (using fastboot image) to make fingerprint work with CustomROMs. However, you need unlocked bootloader to downgrade. Don't flash both gpt and bootloader (if flashed any of these, you will get hardbrick because gpt/bootloader downgrade is not allowed). Also, don't run erase modem commands, they will wipe your IMEI in this case. As soon as you downgrade to stock Nougat, check the fingerprint availibility in Settings. If you can see options related to it, you're good to go - you can install any CustomROM as you normally would and your fingerprint will work.

Hi Andrej_SK, really thanks for your help.
Sorry but I'm pretty new flashing android 6+.

Lets see if i have done the correct step.
Flashed 7.x Nougat following this post: https://forum.xda-developers.com/g5/development/official-stock-moto-g5-cedric-firmware-t3733897

IMEI is OK, fingerprint working perfectly.

This has erased TWRP, so, now i can install TWRP and then install any custom rom?

Yes. Keep in mind that if you want to install any Oreo CustomROM, you need to do it using 64bit TWRP. If you decide to install Gapps alongside with any Oreo CustomROM too, use this tutorial https://forum.xda-developers.com/g5/how-to/how-to-repair-bootloop-oreo-roms-t3791189 to avoid bootloop.

Andrej_SK I have no words to thank you for your help.
I decided to continue using the stock rom, at least until Lineage OS is in a more stable state.
Some functions work better and I really need them.
Again thank you very much!

Hello,
I'm facing the same problem, I came Stock rom Oreo 8.1 and then fingerprint is not working on any custom rom I've tested.
Detail: Project Treble does not even start the boot for me.
I will perform the procedure that you mentioned and leave the feedback here if the problem was solved since I saw in other forums for this device that many are with the same problem.

Edit

I downgraded to the Nougat stock rom and installation rom Pixel Experience 8.1, fingerprint is working for me now =D
Thanks Andrej_SK for the great help

Hey there, can't get my fingerprint to work on LOS 17.1, it's like it's there, but it doesn't react to anything. When I go to the fingerprint settings, it ask me to touch it in order to setup the thing, but when I place my finger on it, it does nothing. Did anyone ever heard of this issue or any fix for it? Thanks in advance.

Did you flash stock Oreo prior to flashing LOS 17.1?

Nope coz I use a Galaxy S7 so Oreo is not compatible with it, isn't it?

You are posting in the Moto G5 forum

If you are using a galaxy s7 I suggest that you go and post your question in the correct rom section for your phone as no one here will be able to help you

Goto the following thread for Los 17 on a galaxy s7 & make sure you are using that build
