This is how I downgraded from Pie to Oreo. I can't guarantee it works for everyone but it worked for me. It required an SD card and a computer.

This is not a guide for the android development savy users but for people who preferred oreo to pie. It works without an unlocked bootloader and an unrooted phone. You will have to wipe your data so backup everything beforehand!

STEP 0) Remove your google account from your phone so you can prevent it automatically updating to Pie on first boot. Go to Settings > Accounts and remove your google account from the phone.

1) First download the zips that include Oreo with the November security patch and the December security update. Put these in the root of the SD card and rename them so you remember which is which.
I have found November Oreo links for both TA1012 and TA1004 but reportedly they both work for all Nokia 8 phones as the main payload.bin file is the same. I used the TA1012 zip with my TA1012 phone.

Don't worry about the TA-1004 stuff, all Nokia 8 software is generic, only google makes a difference between the model IDs.

December Security update can be downloaded here (file is called NB1-488L-0-00WW-B01-488K-0-00WW-B01-update.zip):

2) Boot into recovery mode.
a) To do this on Pie, plug your phone into a computer and wait for the drivers to get installed. Windows 7 downloaded a few megabytes from windows update for this.
b) Unplug your phone and turn it off. Hold Volume up and plug your phone into your computer. Keeping holding volume up.
c) When the sad android appears with 'No command' showing, release Vol+. Hold the power button and press Vol+ to get into the recovery menu.

3) Use the Vol+ and Vol- to navigate down to 'Apply Update From SD card' click the power button to select it. In the next menu select the November Oreo zip file. It'll then verify the downloaded zip and install it. This takes a few minutes.

4) Select Wipe data/factory reset from the recovery menu. You need to do this cause data created on Pie doesn't work on Oreo.

6) Repeat steps 3 & 4 for the December security update. I don't know whether you need to factory reset both times but it shouldn't do any harm.

5) Finally select Reboot system now and it'll boot into Oreo. This takes a few minutes.

6) Don't connect to any wifi during setup. Go to settings > system > about phone. Tap the build number at the bottom until you unlock developer options. Go to settings > system > developer options and disable Automatic system Updates.

Hopefully this helps someone. Thanks to @THMSP, @TeddyBeers and @al mak for various posts that helped me downgrade and write this guide.

That's exactly the way to do it.

Actually works both ways as upgrade or downgrade, as Nokia kindly provides full rom oreo/pie instead of just incremental update.

Setup updates from Android 8 back to Android 9 Again

Useful guide, thanks, but after downgrading from Pie to Oreo how do you avoid being forced to upgrade to Pie again in setup, after you Wipe data/factory reset the phone?

I downgraded back to Oreo from Pie, but when I restart in setup I get forced to search for updates and it finds, downloads and installs the Pie update again, and I dont seem to be able to avoid it?

You have to enable Developer Options then disable Automatic system updates. You will always get the notification that a system update is available but it will not download automatically. Going further, you can even turn this notification off and forget about it.

The problem is that it happens before you get to a point where I know how to access the developer menu to do that.

It happens during the setup wizard, which I can't see how to complete without selecting a wifi network or mobile network, it then searches for downloads and installs the update before it sets up the phone and drops me at the home screen.

I've been having the same issue. I think it is new. I've done the process as early as January 9th with no forced update. As of yesterday it is forced. I've posted my experience in the thread for NOST. Pie may be life now because there are no custom ROMs and I expect all Oreo ROMs to have the force update thing inside them.

@nb111 @hodiedodie

Is it possible to either get through the entire setup without connecting to any network - you will have to forgo logging into a google account at first. Or only use mobile data in the hopes that google is smart enough to realise that people don't want to download 1.5GB on their data plans?

I doubt I'll do this myself but I would suggest doing a man in the middle attack on the phone with arpspoof in a Linux distro. Use Wireshark to see what servers it calls out to. Then I would go in my home WiFi router and block those IP addresses. Then reset the phone and connect to the WiFi network and see if that works.

Ok solved this one, had to Update to P remove the Google Account linked to the Device and downgrade again.
It's Part of the Factory Reset Protection that you cant skip the Wifi and Update Screens.

Do you still have dual sim support? All bands work as before downgrading with 1004 firmware?

I didn't try out dua sim because i have only 1 sim and it works well . don't worry bro, any problem can be solved as long as you done downgrade,it's easy to unlock BootLoader under Oreo ,so you can flash your original official firmware use OST tool or NOST in case any issue . (i downloaded my TA 1052 firmware from google,but i didn't flash it because this 1004 so far no problem)
i downgraded because my battery drained very fast and phone became hot frequently ,but i cant find any other way to downgrade or unlock BootLoader under Pie ,the official unlocking method doesn't working with Pie. i unlock it successful after downgrading by flash this 1004 stuff .

There's a small surprise when flash 1004 firmware,it's showing failed:'version old ,not support downgrade' or something i dont remember,my phone off and stucked at starting log and can restart even holding power button 1 minute,so i thought it fu*ked and bricked,after some time i tried hold power and volume + button finally it switched off and in recovery mode i did factory reset and restart ,Oh sh*t ....... it's Oreo already !!!
haha i wrote too much!

Force shutdown the phone by keeping volume up, volume down and power pressed for some time (2 - 3 minutes). Then directly boot into recovery by holding down volume up while connecting the phone to the PC via. USB.

I successfully rolled back to Oreo.
I wonder if removing the Google account before the rollback prevent you from rollback - install the forced updates - rollback again (I had to do it because I was forced to install the updates the first time, while the second one I had the possibility to skip the configuration)

    Thanks a lot for the tutorial, I success back to Oreo.
    Still, I wonder,can somebody provide Nougat zip firmware like this Oreo one and can be flashed like Oreo?

    Okay, I have tried this and it worked. BUT if you are on the Pie June security update, you will encounter a downgrade error while flashing the firmware. Let it sit first for a few more minutes until it completes the process. The December patch won't work not unless you boot first on Oreo then do the process again. Hope this helps!

    Wiping all data won't delete the sd card data too right?

    It didn't for me

    ASK
    tutorial downgrade 1st page.. can work at security patch 01.08.19??
    anyone tried?

    after update security patch
    my TA1004 GPS always LOST

    As long as you can source a full image file (around 1.5GB) then it will work.

    Don't know why your GPS stops working after a certain security patch. Have you checked whether google location services are enabled? Disable your location, open maps and tap the ? in the bottom right and it should ask to enable it.
