Disclaimer : I don't know Nokia fixed this or not and will this work for you guys but it worked for me and i want the developers to provide mass support for our Nokia 8.1 coz this is highly capable devices made stupid by HMD and fed up of lack of support by nokia

IMPORTANT: Do not verify your device on hmd unlocker app or it won't work for sure

step 1: go to website https://www.nokia.com/phones/en_int/bootloader sign in via Google(i did but don't think so it matters)

Step 2: Fill in required details asked and proceed directly on website and the website alone...do not verify ur imei on the nokia bootloader unlock app or this will not work 100%

Step 3: Agree all the terms and validate...u will get the unlock key from hmd global on email by which u signed in on Step 1

I am attaching the pics of the key i got...also it says it is the key for Nokia 8 but that's typo I guess but I assure u it works coz I unlocked my device also I relocked the bootloader and all the widevine works perfect after relocking the bootloader so no worries if you want to go back to stock also :D:D

I REQUEST ALL THE DEVELOPERS IF THIS WORKS FOR U GUYS PLEASE PLEASE SHOW CUSTOM ROMS AND RECOVERY SUPPORT FOR OUR NOKIA 8.1

THANKS IN ADVANCE

Is there any advice that ROM cannot be upgraded ? My condition is : I followed your steps to do but I couldn't flash unlock key. I returned system and found the "OEM unlock" cannot be enabled. That's why I cannot flash my unlock key.

Maybe its a possibility but low...although just found out yesterday that it depends on which production batch ur phone is made in....Nokia 8.1 manufactured in old batches have unlockable bootloader coz there imei is properly written


So its upon luck....which batch ur phone belongs to

Yes I have the OEM unlock on developer options, but it grayed out and not able to switch on.
And I watched the video in the telegram group you posted, executed the same command, but just didn't work.
Like you said, maybe it's end for me :crying:
Code:
$ fastboot oem device-info
...
(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
OKAY [  0.001s]
finished. total time: 0.001s

Hmmm, looks like site isn't working anymore.
I check the checkbox, but the log in to continue button stays greyed out, tried 3 different browsers.
Sadly, Looks like I have to pay for unlock. Am looking in lineageos development for this device. Too much free time after loosing job:p
