Your generic TWRP works on Oreo & on Pie too, yes??
Also, just to make doubly sure, command should be " fastboot flash boot_a twrp-3.2.3-2-NB1.img " followed by " fastboot reboot ", and that should be it right...??

Yes, just like it says in the thread I linked thread. It works on all security patch versions.
It might happen that you instantly reboot into TWRP instead of the system, but that would be normal on Oreo, at least in my experience. If that happens, just flash Magisk and reboot to disable device verification and be able to boot.
" fastboot oem device-info " returns this:
(bootloader) Verity mode: true
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enable: true
" fastboot flash boot_a twrp-3.2.3-2-NB1.img " returns this:
Sending 'boot_a' (49716 KB) FAILED (Write to device failed in SendBuffer( ) (Too many links))
fastboot: error: Command failed

I even tried installing twrp but in fastboot mode my mobile doesn't get detected and command doesnt even work.i know its drivers pblm i tried installing many drivers but found no use.if you people have best working drivers n adb tools pls share those to me
Yea... Under device manager you can see the device as android and so on and may it has a yellow treeangle, i testet some there to install there drivers by manual and auto-search which doesnt go first but for some reasen it installs correctly after more trias by clicking auto-search but i dont know why

Dont try to install it. Just flash the relevant twrp boot image found in one of the boot image folders of that link. Flash it on your current boot slot and then booting into twrp recovery is as simple as holding the volume up key and inserting a USB cable while holding the up volume key until the twrp splash screen appears
Nope, in that case just stucks at wifi screen. I can't move forward without a wifi connection though I could skip no sim screen.
This is news to me. I have never had this happen on my phone., Ive always been able to skip all the setup screens whenever I sideloaded the stock rom.
You have to remove the gmail account before you reset and set up as new (or the other. Skip, skip, skip and you will complete. Then go do "developers options" in settings, and disable auto-update with toggle.
To everybody about this tutorial: I confirm this method works and this is exactly what I have also done before, by downgrading from 9 to 8.1 with f9cb380bd9c2bf1b6ddebcab9dcf389843eb2d39.zip Those weird numbers are the checksum of the file.
Controll the file integrity with checksum and get the same results as the file name. Algorithm used to generate is SHA1 checksum.
I have the TA-1004, fresh out of the box I updated to Pie, saw the "device not support" message, enabled developer options, looked for the OEM unlocking option, it was grayed out, I installed the zip file anyway, booted into Oreo no problem, enabled developer options again, looked for OEM unlocking, still grayed out. Updated Google Play Services, ran the HDM app, got my key sent to my e-mail, checked OEM Unlocking again and now it is available.
That was months ago. I was able to unlock the phone after that post with no problem.

12If you try to use the bootloader unlocker apk from Nokia and your Nokia 8 has an android version that's past a certain version, the apk will flat out fail with a "Device not support." error message. And chances are, your Nokia 8 will be at an incompatible android version. So to unlock the bootloader, you will need to downgrade your phone to a legitimate version of android 8.1.0 so the apk will not error out and get you a verification code. This guide will show you how. NOTE THAT THIS METHOD WILL ERASE ALL INTERNAL DATA ON YOUR PHONE.

This update zip is what you need for the TA-1004: https://android.googleapis.com/pack.../f9cb380bd9c2bf1b6ddebcab9dcf389843eb2d39.zip
It may be different for the TA-1012, but according to that earlier post, it does not seem to be the case. Nevertheless, just to be safe, here's the zip for the TA-1012: https://android.googleapis.com/pack.../139c94fd08f52fbd3b852ab4ef5c6515fffb784e.zip (I don't have a TA-1012 so I wasn't able to test this particular zip.)
So basically, to make sure there's no problems, make sure in the Developer's options on the phone that OEM unlocking is enabled, then put your SD card into the phone. Plug the phone into your computer. Copy the update zip that you need somewhere onto the SD card. Disconnect the USB cable. Shut down the phone. Then, while holding down the Volume Up button, reconnect the USB cable. You should see a sad android with "No command" displayed. Now release the Volume Up button. Then hold down the power button and then JUST PRESS once on the Volume Up button. You should be at a recovery menu. Using the volume keys, scroll down to the 'Apply update on SD card' option and select it. Select the zip that you copied over to the SD card earlier and then let it install for a while. It will probably pop up with a 'timestamp too old' error, but just ignore this. The update will install anyway. Then once it's done, do a factory reset on the phone and then shut down. MAKE SURE THERE'S NO SIM CARD IN THE PHONE.
Now that's out of the way, boot the phone up again and just click through the first-time setup screens but DO NOT ENABLE WI-FI or any kind of internet connection. We don't want the phone to update itself back to Android 9. Now plug the phone in again. Copy the bootloaderunlocker apk from Nokia's website onto the phone. Install it. Put in the email address you want the unlock key emailed to. Then voila! You'll get the verification code. Put it into the form on Nokia's website and you'll be emailed an unlock.key file. From there, the site will tell you how to proceed.
A HUGE thanks to: THMSP and frankoid
They did all the work. <34
Yes you can, if you are on the december update of pie then see this thread for a pre-rooted boot image https://forum.xda-developers.com/nokia-8/development/android-9-0-pie-patched-boot-img-t3875977
If you want to root january or feb pie updates then follow the tutorial here https://bit.ly/nokia-nb11
Because I don't expect people to dig around in all the Nokia 8 Guide threads to find the exact and, to my knowledge, only way to unlock the bootloader. Furthermore, I found this solution in a sort of unrelated thread, which would make the solution even harder to find for the average user.1
