Nokia 8.1 is currently my primary smartphone. I will capture the OTA update URLs each month and add to this post. You can use the OTA URLs to download the update file manually and install it on your Nokia 8.1 (or Nokia X7 running on Global ROM).
The updates are captured from the Indian variant (TA-1121). The update files should be the same for other regions (TA-1128, TA-1119), except for some regions (for example Russia) where Nokia offers a different software experience.

Android Q Beta
These builds will not be fully stable. So, use them at your own risk. You can use these on Nokia 8.1 and Nokia X7 which is converted to Android One. Do not use on Nokia X7 running on CN builds. You can also download the Android Q beta buids by enrolling into the Developer Preview program.
The files are mirrored to Google Drive because the official link expires quickly.

How to install manually
You can install the update file from the Android system or from the stock recovery mode.
To install from within the system: Rename the file with the internal build number. For example, if you have downloaded the 2.52B update, then rename it as PNX-252B-0-00WW-B01-update.zip. Don’t forget to change the 252B part with the internal build number mentioned against the update file.
After that copy it to the file to your internal storage outside of any folder. Then reboot the phone. You will receive an update notification after some time.
To install from recovery mode: Copy the downloaded file to the MicroSD card in your phone. After that, reboot the phone to the Android recovery mode and select Apply update from SD card. Then select the update file to start installation.
