Just going to dump all the info I've found about this device into this thread. All the threads pertaining to this thread are in Russian and I can't read Russian, so this might be helpful to any English speaking owners of this tablet.
Special thanks to Telegram user @SSDD_1744 (don't know your XDA/Reddit user, I'm sorry) for basically spoonfeeding me all these instructions!
WARNING: If you need to flash to stock for whatever reason, be sure to download a image file specific to your country. If you don't, you'll hard brick your device that can only be fixed QPST (supposedly).
Rooting:
(Tested on 5.0.2)
Install KingRoot. Let it root your device.
Install Super-SU Me, to get rid of the bloatware that comes with KingRoot.
Installing Xposed:
I used Flashify to flash TWRP. Be sure to flash the right version though (2.8.7.7 v2) or else you won't be able to mount cache.
Then download Xposed (version sdk21 ARM) and flash it.
WARNING: Flash v1 of the modded TWRP and you won't be able install any apps after flashing Xposed.
Unbricking:
Still working on it. Downloaded QPST but have not been able to get QPST 2.7 to read the tablet.

All transactions with their phones / tablets are performing at your own risk !!!
To get started, read this post from start to finish and only then proceed to action!
Introduction
This instruction is written based on my own experience obtaining root on their plates, and then on the Xperia M2, bought plemyashki. For instructions attached versions of applications that were relevant at the time, the new version can download the relevant topics on the forum, there will find all information on how to work with the proposed programs and algorithms for their actions (links to topics added).
For all the action with your phone / tablet you are responsible for yourself!
Download all the necessary tools to obtain Root (of instructions / topics on the forum), obespechte for phone / tablet access to the Internet (Wi-F / mobile data) and let the phone settings / tablet installation from unknown sources.
Needed Downloads
KingRoot_V4.5.0B202.apk (6.76 MB)

Next in series:
1. Install KingRoot .
Get Ruth's right, in the device may reboot.
2. Set SuperSU-Me, .
Run the grantor, the program deletes KingRoot and Chinese KingUser with replacement SuperSu.
Remove the longer SuperSu-Me the desired program.
3. Obnovyaem SuperSu to the latest version. Then set PRO-key .
Installing Pro-key Optionally !!! Use Cases SuperSu without installing key .
4. Open SuperSu and on-demand update binary SU normal way. After a successful update, confirm the request to restart.

If you want to open the engineering menu, type " * # * # 4636 # * # * "
To boot into fastboot, restart/turn on the device and hold volume up. It'll pop you into a menu with three options.
To boot into recovery, from the fastboot screen (three options), use the volume buttons and navigate to the second option "factory reset" and hit power to confirm. It'll boot into recovery.
=====================================================================================
Recommended way to flash ROMs:
1) Download TWRP. Use adb to boot (NOT flash) into TWRP. Flash ROM there.
2) use KingRoot to root. Use Flashify to flash the ROM.

I see that Lineage OS is supported on Z380KL. However, I found the wiki spec showing Snapdragon 410, but I found Z380KL in Asia with Snapdragon 615. Before I commit, I'd like to know if anyone knows whether LineageOS is fully compatible with Z380KL with Snapdragon 615 chipsets? Thanks.

Flashing TWRP on 6.0.1 (Sept 1, 2016 patch):
1) grab your drivers (W10: boot into "no driver signature verification mode" to install the drivers needed for fastboot)
https://drive.google.com/open?id=1cGcoDCvmTxfXWNTG0iOXHw1WScmYBrKS
2) turn on debugging
3) type in "adb devices", verify that your computer sees your tablet (if you don't have ADB/Fastboot, get https://forum.xda-developers.com/showthread.php?t=2317790)
4) type in "adb reboot bootloader"
5) you'll see three options: 1. Enter SD DL mode, 2. Factory Reset, 3. Exit update mode
6) type in "fastboot devices", verify that your computer sees your tablet
7) grab your TWRP file (http://vasy.ru/TWRP/P024/) and type in "fastboot flash recovery [replace w/ location of the TWRP file].img"
8) once it says "finished", click factory reset mode (use volume buttons to navigate, power button to enter)
9) it should reboot into TWRP, slide to allow modifications
10) Boom, TWRP is installed.
OPTIONAL, BUT HELPS TO KEEP TWRP INSTALLED: Flash Magisk.
That way, stock recovery won't overwrite TWRP when you reboot.
IF YOU WANT TO KEEP TWRP BUT DON'T WANT Magisk:
1) After first boot into TWRP, turn off tablet.
2) Then turn on and hold Volume Up + Power. That will boot you into Bootloader Mode.
3) Go into factory reset and it should boot you into TWRP.
Now, it's safe to boot into the OS.
(TL;DR: Boot into TWRP twice before booting into the OS or else stock recovery will overwrite TWRP.)
Flashing LineageOS:
1) DL LOS from https://download.lineageos.org/P024
2) DL GApps from http://opengapps.org/ (choose 7.1)
3) boot into TWRP
4) go into Wipe, slide to wipe
5) go to Install, click on LOS file > add to queue, click on Open GApps file > add to queue, flash
6) wait til it's done, click "reboot"
7) wait a while (took mine 3 or so minutes to boot)
8) enjoy!

Thanks for the tutorial, I had already dared to flash twrp recovery before you wrote this tutorial...
I believe my bootloader is still locked. And I could not reproduce/ write exactly what I did. But, in my case, just for information, when I want to go back into twrp, I can boot into bootloader (power volume up) and then option 2 reset the device gives me the twrp... I am not sure if that is how you get it, but for me, I still had twrp.
I think i will install magisk after reading your post.

I don't think unlocking the BL is necessary for flashing LOS. But yes, that's how I get into TWRP as well.
Hello I'm new in the forum and I write from Italy, yesterday unfortunately I had the brilliant idea to downgrade my Asus z380kl through ADB, Fastboot and TWRP from pc so far so good, I go to flash the new rom and gives me error, I try to restore the backup here too error result? Tablet locked the only way to make it recognize to the PC is with ASUS FLASH TOOL ROM problem in format.raw unobtainable not even on the Russian site. Any good soul has the possibility to let me download it? Thanks, Sorry English but it is a translation of the very useful Google translate.

Can you still access fastboot, then at least you can flash twrp as described before in this thread and install from twrp lineageos p024 (lineage-14.1-20180105-nightly-P024-signed.zip) and Open gapps to get google playstore etc , select Arm, (not 64) then version 7.1, then Pico would work.
If you have twrp, you at least can still use your asus... I have found no way to flash original stock... stock must not be flashed from twrp.
Since you mention twrp already used, you can try: turn your device off, then press volume up then the bootloader menu comes, select 2: reset to enter twrp(where it says reset. if you had flashed twrp, that is how you can get into twrp) from there, install lineage os and gapps from micro sd card
My rom is MMB29M.WW_P024-V5.9.4-20170613

I assume this is on stock rom ? What version of magisk would work? I found I can be back at stock with my twrp backup so ..
But magisk 15.3 zip failed to install on stock-
I also used supersu v82 working on stock, or lineageos.
Would you know what magisk works on lineageos?
I like the exsd extension of magisk so I would like to try it on this device, either stock or lineageos

Yes it was. I flashed 15.2 on both stock and LOS. I've heard of some issues with 15.x so you can try .2 or 14.x.

What error was given? What do you see when you connect it to a computer? What does "tablet locked" mean? Would help if you gave some pictures too.
I'm currently in the process of getting the RAW files/service ROMs for AFT but I don't have an ETA on when I'll be able to get that.
No on the tablet I have not installed TWRP and no other recovery.When I go into the original recovery of the tablet there is always the screen with the lock closed at the bottom right and there is no way to show it to the PC even with adb sideload, l 'only program that recognizes me the tablet is Asus flash tool, however, as I have already written the damn ROM in RAW format is untraceable.

Y9 2018 running Android 9 Custom ROM
(Havoc OS+MicroG)
Hi, so I landed on this forum a year ago, thinking that it would be impossible for me to one day unlock and tweak my Huawei Y9 2018.
Today everything works fine for me as I managed to install a custom ROM after unlocking the bootloader. I'll detail you step by step what I did, I'm new here so this is obviously not the only way, I'm just telling you what I did to make it work, and of course I am not responsible if anything wrong happens to your device, many times during the process I did things wrong and I bricked the phone, but you should always be able to come back to step 1 and restart fresh.
STEP ONE: INSTALL STOCK ANDROID 8 FIRMWARE (before June 2018 security patch)
For this step all you need is an SD card (and a computer if the phone is bricked).
Go to here and type in your phone model, I have the FLA-LX3 so I took this file which is at the bottom of the result list.
Afterthat extract the zip and copy the filed called update.APP to a folder called dload in your SD card.
Turn off your phone with the SD card placed inside and boot it from the SD card. To do that, you have to press volume up and power button at the same time for 5 seconds.
The installation should start and you will soon boot back in Android 8.0.0. Quickly reach the settings to check if you have successfully downgraded before June 2018. Otherwise the rest won't work. Finally, rename dload folder in your SD card to something else so that next time your phone won't try to install a system from the SD card.
STEP TWO: FIND YOUR BOOTLOADER CODE
If you already know your bootloader code, directly go to step 3.
This is a tricky part, as you already know there is no official way to get your bootloader code. There are different approaches to get the code. Both need a computer.
A free one can be found here but I didn't use it personally. It's a simple brute force attack to find the code, it can be extremely long so most probably not the best one.
A second option, which is most used is the DC-unlocker tool for Windows that will find the bootloader code in couple of seconds. You have to use 4 credits (4$) to perform the action "Huawei Qualcomm Read Bootloader Code (up to Android 8)". The tutorial can be found here
Once you know your code, save it everywhere !!!
STEP THREE: UNLOCK BOOTLOADER
For this step you will need a computer with ADB and Fastboot commands. (download the command line tool for Windows/Mac/linux from here)
Go to phone settings, activate OEM unlock and USB debugging (you might need a WiFi connection to enable OEM unlock). If you type adb devices in your shell you should see you device in the list.
Type adb reboot bootloader to enter fastboot mode.
If you type in fastboot devices you should see again your device in the list.
Type in fastboot oem unlock *paste your code here*
On our device confirm unlock and the device will reboot after a factory reset.
STEP FOUR: FIND THE RIGHT GENERIC SYSTEM IMAGE
There is no official custom ROM for Huawei Y9 2018 but the phone is compatible with Generic system images, which are universal ROMs (all listed here). To be sure quickly reach the browser to download Treble Check app from here. This app will tell you wether or not you can install GSI images on your phone. If Projet Treble is ticked then you are good to go. If Seamless updates is ticked then you have an A/B system, if not then you have an AONLY system. Finally the CPU Architecture tab should tell you if you are on ARM64 or something else.
The GSI rom I chose is Havoc OS, it is the most compatible for Huawei phones. It is an Android 9 rom built on top of Lineage OS and adds up some functionalities, fixes for Huawei phones, and signature spoofing for MicroG to work. Go to this link and choose the right Havoc version based on the Treble Check app.
STEP FIVE: INSTALL HAVOC OS
Once you downloaded the connect img file connect your phone again and enable USB debugging, type in adb reboot bootloader to enter fastboot, and enter fastboot flash system *GSI rom path*
Once done, unplug device from computer and reboot to eRecovery by holding power and volume up for 5 seconds (just like in step 1 so make sure no SD card with dload folder is placed inside the phone). Once in eRecovery perform a factory reset and after that hit reboot system. Your device should now boot with Havoc OS !
STEP SIX: install F-Droid MicroG and Aurora Store (Alternatives to Google ecosystem)
Go to the browser and install F-droid from their official site. Next add the MicroG repo to F-droid to install and activate all the replacements to Google services. You can finally install Aurora Store from F-droid which replaces the official Play Store.
That's it folks!

A second option, which is most used is the DC-unlocker tool for Windows that will find the bootloader code in couple of seconds. You have to use 4 credits (4$) to perform the action "Huawei Qualcomm Read Bootloader Code (up to Android 8)". The tutorial can be found here
Once you know your code, save it everywhere !!!
STEP THREE: UNLOCK BOOTLOADER
For this step you will need a computer with ADB and Fastboot commands. (download the command line tool for Windows/Mac/linux from here)
Go to phone settings, activate OEM unlock and USB debugging (you might need a WiFi connection to enable OEM unlock). If you type adb devices in your shell you should see you device in the list.
Type adb reboot bootloader to enter fastboot mode.
If you type in fastboot devices you should see again your device in the list.
Type in fastboot oem unlock *paste your code here*
On our device confirm unlock and the device will reboot after a factory reset.
STEP FOUR: FIND THE RIGHT GENERIC SYSTEM IMAGE
There is no official custom ROM for Huawei Y9 2018 but the phone is compatible with Generic system images, which are universal ROMs (all listed here). To be sure quickly reach the browser to download Treble Check app from here. This app will tell you wether or not you can install GSI images on your phone. If Projet Treble is ticked then you are good to go. If Seamless updates is ticked then you have an A/B system, if not then you have an AONLY system. Finally the CPU Architecture tab should tell you if you are on ARM64 or something else.
The GSI rom I chose is Havoc OS, it is the most compatible for Huawei phones. It is an Android 9 rom built on top of Lineage OS and adds up some functionalities, fixes for Huawei phones, and signature spoofing for MicroG to work. Go to this link and choose the right Havoc version based on the Treble Check app.
STEP FIVE: INSTALL HAVOC OS
Once you downloaded the connect img file connect your phone again and enable USB debugging, type in adb reboot bootloader to enter fastboot, and enter fastboot flash system *GSI rom path*
Once done, unplug device from computer and reboot to eRecovery by holding power and volume up for 5 seconds (just like in step 1 so make sure no SD card with dload folder is placed inside the phone). Once in eRecovery perform a factory reset and after that hit reboot system. Your device should now boot with Havoc OS !
STEP SIX: install F-Droid MicroG and Aurora Store (Alternatives to Google ecosystem)
Go to the browser and install F-droid from their official site. Next add the MicroG repo to F-droid to install and activate all the replacements to Google services. You can finally install Aurora Store from F-droid which replaces the official Play Store.
That's it folks!

Hi there these steps seems easy enough.
But I had to ask why you chose android 9 and will higher versions work correctly?

Hi guys!
I am new here, recently unlocked bootloader (guide)
Eagerly want to flash lineage OS, but can't. Always ended up multiple reboots or some black screen.
Can anyone write step by step guide?
Currently using Android 9 Stock ROM (came back from android 10 stock rom using this method)
Used TWRP from here
Have you read the wiki page for LineageOS for N 6.1?
Info about PL2 | LineageOS Wiki
wiki.lineageos.org
Update: Installed.
NOTE: It is recommended to update your stock ROM to Android 10 before flashing this custom ROM. ( this method )
Just reboot to bootloader and download this TWRP for our Nokia 6.1, boot it (fastboot flash boot twrp.img), and everything will be fine.
Power + Volume Up
and leave power button when you see the android one logo but keep pressing volume up
Now you can flash TWRP.zip file.
Format Data by typing yes
Reboot to TWRP.
Flash latest ROM zip via TWRP
Switch to an alternative slot (if you are on slot a, switch to b if you are on b, switch to a) - (if you don't know where is the option to switch: reboot >> select slot)
Reboot system
Thanks to this guy https://forum.xda-developers.com/t/rom-12-1-unofficial-pixysos-pl2.4454103/
hello @chsiva, I would like to know if when installing the version of lineageOS 19.1 you used the lineageOS recovery, in my case I have reinstalled LineageOS 19.1 more than once without any problem. In fact, it is not so necessary to have the latest version of Android from the manufacturer installed to be able to install this version of lineageOS, I will explain the steps to be successful in the process.
1) Do not leave any custom recovery as permanent.
2) Since I have Windows 10, I had to look for the drivers that really work for Nokia, in which there are 2 drivers that are needed and apply some additional configurations to the main installer, one of them is compatibility with old versions of the operating system.
3) Download the tool that includes fastboot + adb and verify that the device is really recognized by the operating system regardless of the mode in which it is.
4) Being in the stock version, I recommend you to factory reset the device, then configure it.
5) Enter the download mode and through the cmd and in the adb mode use it to change the slot A/B (A or B), In both you will have to install the lineageOS recovery.
6) Having the recovery installed in both Slots (Remember to use Fastoboot to install the recovery) I recommend you to be in Slot B to proceed with the installation of the rom.
7) Then access the recovery, in my case I decided to perform a data format from the recovery and then select the ADB installation, I recommend you disconnect the device before accessing this option, when you access this option, connect the device to the computer (the recovery should indicate that you are in slot b before continuing with this).
8) Install the lineageOS rom and after it finishes, reboot the device and wait for it to boot.
9) When booting into lineageOS, apply settings and then reboot back into recovery mode.
10) Install the necessary Gapps to have the basic services of google, remember to be in slot b to continue, after installation, restart and when starting, connect to a network and configure.
11) The normal thing is that it is configured but in a partial way, the contacts that you have saved in your google account should not appear if you have it saved, if this happens, you only have to reset the device from the factory.
12) When starting again, apply the configuration connected to the network since the gapps are already included in the device, more configuration options should appear than the previous time when you installed the gapps and at the end the contacts should appear.
13) now if you can install magisk in version 25.2 if I'm not mistaken, remember to change the .apk to .zip and from the recovery install it from slot b and reboot.
14) and the last thing you need is to install 2 modules to certify the device with magisk (before this, I recommend you activate the option to hide root from applications, magisk should request a reboot, before rebooting, apply the deny settings of root to the applications that you deem convenient, but those of google if or if they have to be denied, in google services, mark all the options to deny root in its entirety).
15) For this procedure you will need a terminal and from the terminal, type the command (props), then press ENTER and sign the device.
16) and then delete data from play store and google services and then reboot the device and voila, your device is ready to use.
-In the event that you do not have a windows operating system, you can use the virtualbox tool and if it is possible to install the version of windows 7 ultimate, although you will have to install some necessary drivers so that you do not have a problem with the execution of applications from the virtualized system.
