The need for manually installing updates

Software updates for the Nokia 6.1/6.1 Plus, like any other Android phone, are rolled out over-the-air (commonly known as “OTA Updates”). And due to the nature of these OTA updates, they are rolled out in phases and influenced by factors like region, carrier, model number, etc.

And so, when HMD (the Original Equipment Manufacturer) releases an OTA software update for your phone, it could take some time before it’s actually available for your specific unit. This time period could range from a few days to weeks.

But you can skip the waiting, and manually upgrade your phone to the latest software version right away. This could be done by downloading and manually installing (sideloading) the OTA update ZIP file on your Nokia 6.1/6.1 Plus using the in-built stock recovery. Manually updating your phone using this method doesn’t require you to unlock the bootloader or do anything else that could affect your phone’s integrity.

Through this page/repository, you can download all Nokia 6.1 and Nokia 6.1 Plus OTA update packages, including that of the October 2020 security update, and further follow the provided instructions to manually install it.

Prerequisites

Before you head to the instructions, make sure that you fulfill the requirements listed below. This will ensure that the OTA installation process goes smoothly.

  • To sideload an OTA, you will need a Windows, macOS, or Linux PC.
  • Take a full backup of all your data first. We can’t help but emphasize this more. Although installing the OTA updates manually using the instructions provided here will not erase any data, it is still a good idea to have a backup if anything goes wrong. You can go through this detailed post for instructions on how to do it.
  • Charge your Nokia 6.1 Plus to a sufficient battery level to prevent it from suddenly powering off during the update process.

About OTA Updates

OTA updates are available in the following two forms or types:

  • Incremental OTA updates: These can only be installed over a specific software version and are small in size. Most OTA packages of monthly security updates are incremental in nature. For example, the V4.15L January 2021 security update can only be installed if your Nokia 6.1/6.1 Plus has the V4.15K December firmware installed.
  • Full OTA updates: These are much bigger in size and can be installed over any previous software version. Most major Android version updates are full OTAs. For example, the latest Android 10 update can be installed on your phone irrespective of the previous Android Pie software installed.

So, if you’re installing a monthly security update over a previous one, take note of the current software version installed on your phone first. You can get this info by going to ‘Settings‘ > ‘About phone‘ on your phone. Then download the OTA package of the next update accordingly.

If you’re going to install a full OTA package like Android 10, then the installed software version doesn’t need to be accounted for.

How to Manually Install OTA Updates on Nokia 6.1 and Nokia 6.1 Plus

To manually install software updates on Nokia 6.1 and Nokia 6.1 Plus, you will need to sideload the OTA zip package via the stock recovery. The process is extremely simple. You just have to download the OTA update package, boot your phone into stock recovery mode, and enter ADB sideload command on your PC to sideload the OTA.

It may sound confusing at first, especially if you’re new to dealing with manual OTA installation. But don’t worry, the instructions below will take you through the complete process in a step-by-step manner.

Step 1: Install ADB on your PC

The first step of the process is to install and setup ADB on your Windows, macOS, or Linux PC. ADB is a basically a command-line tool used for debugging and other purposes like sideloading updates in this case.

So, start by downloading the Android platform-tools package according to your PC’s operating system from below.

Once you have downloaded the package on your PC, all you have to do is extract the ZIP file using an archive tool like 7-Zip. The extracted “platform-tools” folder should contain the required ADB binary and other related files.

For easier access, move the ‘platform-tools‘ folder to the root of C:\ drive on your Windows computer, or to the ‘Documents’ directory if you’re using a Linux or macOS PC.

Step 2: Download the OTA Package and Move it to ‘platform-tools’ Folder

Now, download the OTA zip file of the software update that you want to install. Once downloaded, move the file to inside the “platform-tools” folder you extracted during the last step. This will allow the command-line to identify the OTA package while sideloading.

Step 3: Launch the Command-Line on your PC

With ADB and other platform-tools in place, you now need to launch the command-line window within the same folder. To do this:

  • On Windows: Open the platform-tools folder, then hold the SHIFT key on your PC’s keyboard and right-click on any empty space inside the folder. Then select ‘Open PowerShell window here’ or ‘Open command window here’ (Depending on Windows OS version).

  • On macOS/Linux: Launch the Terminal and use the ‘cd’ command to change its directory to the platform-tools folder. For example, if you have moved the ‘platform-tools’ folder inside the ‘Documents’ directory, then the command should look like the following:
    cd Documents/platform-tools

Once you have done this, your PC should be completely ready to sideload the OTA package.

Command-line usage: When entering the commands provided below, make sure to precede them with a dot and backward slash “.\” in Windows PowerShell or with a dot and forward slash “./” in macOS/Linux Terminal.

Step 4: Verify ADB Connection between the phone and PC

Enable USB debugging on your Nokia 6.1/6.1 Plus now and connect it to your PC via a USB cable. Next, enter the following command in the PowerShell/Terminal on your PC to ensure that your PC can communicate with your phone over the ADB interface:

adb devices

Select ‘Allow‘ if you see a prompt on your phone’s screen to allow USB debugging.

Allow USB Debugging on your Nokia 6.1 or Nokia 6.1 Plus

 

The command should return a unique device ID. In case it doesn’t, it means that the proper ADB drivers are not installed, in which case, you can download and install them from here.

Step 5: Boot your Phone into the Stock Recovery mode

Now, to install the OTA update, you have to boot your Nokia 6.1/6.1 Plus into the stock recovery mode. To do this, simply issue the following command:

adb reboot recovery

Your phone should instantly reboot and automatically enter the stock recovery mode. You should now see the ‘No Command‘ screen with an Android bot, as shown in the figure below. To enter the stock recovery, simply hold the Power key and tap the Volume Up key once.

Enter Stock Recovery on Nokia 6.1/6.1 Plus - "No Command" Screen

 

Step 6: Enable ADB Sideloading in Stock Recovery

For the stock recovery to accept the OTA installation, you must enable ADB sideloading. To do this, use the Volume keys to move the selector to ‘Apply update from ADB‘ and press the Power key of your phone to confirm the selection.

Select "Apply update from ADB" in Nokia 6.1/6.1 Plus Stock Recovery

 

Step 7: Use ADB Sideload to Install the OTA Update on your Nokia 6.1/6.1 Plus

Now, enter the following ADB command in PowerShell/Terminal to start sideloading and install the OTA update on your Nokia 6.1 or Nokia 6.1 Plus:

adb sideload ota-filename.zip

Here, “ota-filename.zip” needs to be replaced with the actual filename of the OTA package you’re sideloading. For instance, if you have downloaded the OTA file of the latest January 2021 security update for the Nokia 6.1 Plus, then the command should be the following:

adb sideload 0a1e1b9b912ef5f8a12e455adaf6696ba152c9ef.zip

Enter ADB Sideload Command to Install OTA Update on Nokia 6.1/6.1 Plus

As soon as you enter the command, the stock recovery will begin installing the OTA on your phone. The progress for the same should be shown at the bottom of your phone’s screen. The process could take from a couple of seconds to a few minutes to complete, depending upon the size of the file. So, leave the USB connection undisturbed.

Step 8: Reboot your Phone into the Updated OS

Once the update has been installed, use the Volume keys to move the selector to the ‘Reboot system now‘ option and confirm it by pressing the Power key.

Select "Reboot System Now" in Nokia 6.1/6.1 Plus Stock Recovery

That’s it! You have just successfully updated your Nokia 6.1 or Nokia 6.1 Plus to the latest software version by manually installing the OTA package. You could repeat the same process to manually upgrade your phone every time a new update is released. We will give it our best to keep the download links up-to-date.
