How to flash Lineage 15.1:
!NEW AND THE ONLY RECOMMENDED METHOD!​

You must be on Oreo. Before flashing delete all your saved fingerprints and screen locks.
1. Reboot to bootloader (Bootloader must be unlocked)
2. fastboot boot recovery-xx.img (in ADB)
-> Grab official recovery from here: https://xdaforums.com/mi-a1/development/recovery-twrp-3-1-1-0-touch-recovery-t3688472
3. Wipe System/Data/Cache/Dalvik
4. Flash Lineage & TWRP Installer zip
-> Grab TWRP installer from the link above
5. Reboot to recovery using TWRP Recovery (In TWRP go to Reboot -> recovery)
6. Flash Gapps/MicroG (opengapps.org -> platform ARM64 -> Android 8.1 + Variant [IMO pico is your best pick])
7. Flash Magisk [latest] if you want ROOT (I bet you want!)
-> Grab Magisk from here: http://tiny.cc/latestmagisk
8. Reboot to System

How to update from previous build:
If you don't have permament TWRP, just follow the method above.
If you have permament TWRP:
Delete all your previous fingerprints (just for safety)
Boot to TWRP
Wipe Data/Cache/Dalvik (wiping is optional - but clean flash is always encouraged)
Flash Lineage ROM zip file
Flash Magisk
Flash Gapps/MicroG
Reboot

If you have signal stability issues, try this:
Dial *#*#4636#*#*
Go to Phone information
Set Preferred Network Type from Unknown to LTE or WCDMA only

WHAT IS WORKING:​

Q&A

What does NIGHTLY mean?
Nightlies are automatical builds (every few days), so it mean you will have frequent updates, recent Lineage changes will be present in a rom. Also fixes and new stuff will come faster!


How I can go back to stock?

Grab Mi A1 tool from here: https://xdaforums.com/mi-a1/how-to/tool-xiaomi-mi-a1-tool-drivers-unlock-t3742857.
Install it in your PC, enable USB Debugging on your phone, plug phone to PC
Click Flash Stock ROM button
Click Download ROM and wait
Click FlashAll. Your phone will reboot to fastboot and it will start to flash stock :)
[You will loose all your data, so backup is encouraged]


Do I need to downgrade to Nougat before flashing?

Not anymore :) It's advised to flash from Oreo


After update my FP don't work, wat to do?!

Make a clean flash using method from OP. If clean flash won't help, try: https://xdaforums.com/mi-a1/development/xiaomi-mi-a1-tissot-firmware-flashable-t3759886


Is Dolby working on Lineage 15.1? How to install it?

Just download Magisk module and enjoy!


My mobile signal is unstable. Is there a way to fix it?

Yes, see a workaround from OP


Why Selinux is permissive, not enforcing?

In unofficial builds Selinux is permissive. If the build goes official, it will have Selinux set to enforcing. Don't worry, just wait for official version!


Is this rom stable enough to be a daily driver?

Depends what you need. Check buglist - if these bugs don't bother you - it can surely be a daily driver


When new build will be avaible?

Don't ask for ETAs. Developers are working hard (in their free time!) to fix a bugs - we just need to wait patiently. :)

Some users are experiencing wifi issues (myself included). How can i fetch the log?
Steps to reproduce: Turn off bluetooth. wait a moment... wifi will start dropping connection a lot. To fix, just turn on BT again.

Headphones are working!

By the way. I found a bug. The equalizer don't work correct. Everytime when you skip a song you must tap the bass regulator again in the equalizer app. When you don't do it, it plays without bass.

Installed and used for 24 hrs with no apparent problems. No fingerprint bug.
All the other bugs reported in OP exists.
Returned to Stock since I found it a bit smoother.
I will wait for a more stable official build
Good work so far

How to flash Lineage 15.1: ​
There's a few working methods. First, most popular one:
....

Third, last one:
Boot to the recovery (same recovery as method above)
Wipe system and cache ( data is optional if your are on Oreo)
Check which partition you are on (A or on partiton B)
Flash the rom on one of the partitions
Flash the twrp installer zip
link: http://www.mediafire.com/file/338o7cl72z52rzz/twrp-3.2.1-1-installer-tissot-FIXED_By_DroiDMester.zip
Reboot back to the recovery
Switch to the second partition
Flash GAPPS/MicroG and Magisk
Reboot
Click to expand...
Click to collapse

Sorry to pick this up again but the last method implies that TWRP will be installed permanently as default recovery, right? I was successfull only with the first method however I always end up in LOS recovery when try to enter recovery with Vol-up+Power after everything is installed.
I'm sure we all agree that this whole recovery mess needs to be sorted out quickly. Even experienced users are hitting snags and flood the board with questions :(.

I'm not sure why the issues. I followed the steps in the OP, except I didn't flash TWRP, I just boot to it temporarily.

I did the following:

Flashed 7.11.18 ROM using MiFlash.
Booted into the ROM, set it up minimally.
Rebooted to fastboot, unlocked bootloader
booted temporarily to deadman TWRP, wiped system/cache/dalvik/data (just to be sure it is completely clean)
rebooted and then booted back into deadman TWRP
flashed LOS.
rebooted and then booted back into deadman TWRP
Flashed gapps and magisk.
rebooted to OS.

hey guys! If you are in STOCK OREO you need to downgrade to NOUGAT FIRMWARE version 7.11.18 because DEADMAN'S TWRP will NOT WORK PROPERLY in STOCK OREO! DEADMAN'S TWRP is made ONLY to WORK ON NOUGAT rom that's why you get those errors!
