If 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.

HMD unlock tool doesn't seem to be working anymore on 8.1 November patch:
After downgrading, wiping and updating play services:
HMD unlock tool tries to establish communication, shows "loading" for very long and then gives a connection error:
"Network Error, Please help ckeck your internet and try again."

Has anyone else experienced this?

From a quick Wireshark analysis it seems the tool is making a request to googleapis and then to amazonaws but the content is encrypted using TLSv1.2, so no idea what really happens...

Yeah, the bootloader unlock is a pain in the arse. i have the same issue. i don't understand why hmd made it so difficult. force to downgrade, disable the oem-unlock, then update the apps again and now the problem with the network error.
could you solve the problem by now?

Nope, just upgraded to 9.0 again and started looking for a new Phone. When I bought it, I was hoping that there would be more support from HMD, because of the nearly stock Android. They don't seem to care anymore and the community couldn't get formed. Sad for HMD. They could have been evolved to a Real insider tip. In my opinion, don't wait for it.

Hello all,

I have Nokia 8 and have downgraded using the zip provided and also installed the bootloaderunlocker apk. I opened the app, added the email and pressed the confirm button but instead of success I got "Network error, Please help check your internet and try again". Don't know what to do. Any solutions?

Nope, just some posts earlier Scheusso and I reported the same Problems. No solution that I know about. Seems that HMD doesn't care anymore. I am sorry.

after this my phone struck on nokia logo, please help,,,,
i'm training to recovery mode \ download mode but not working both

I now have the same issue with my TA-1052. Phone won't start and can't enter recovery mode.

The 8.1 downgrade applied, but upon reboot, I'm not able to enter recovery mode: power + volume-down, continuing to hold volume-down until recovery menu (which never comes).

I've tried connecting via ADB, but it's not detected.

The phone displays "Powered by Android" for about 30 seconds. Then transitions to "NOKIA" indefinitely. It'll eventually run out of battery, or I can hold power + volume-up to force power it off.


Is there a way to recover from this, or is my phone bricked?

    Ok. So after rooting, is it possible to install Pie update and still have root?
    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-nb1

    why another topic ?!

    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.

    I managed to get the key. Servers are working.
