How to Update Nokia 8

Nokia 8 is the latest Android based device released by HDM Global and it’s indeed an interesting smartphone. It’s not the best phone available on the market, or the most affordable one, but it’s still quite impressing in term of design and performance. Moreover, it runs on a pure version of Android and it promise in-time updates for at least another year or even more. So, knowing how to apply updates on the Nokia 8 isn’t actually optional. That’s why we are here to help you out.

This tutorial will show you how different update operations can be successfully completed on the Nokia 8. So, shortly, by using the guidelines from below you can see how to apply an OTA, how to adb sideload a firmware, how to manually install the full firmware package and how to flash a custom ROM software such as Lineage OS, AOKP or Paranoid Android. Thus, you have it all: keeping everything by default through stock Android update or tweaking your Nokia 8 for customizing and optimizing anything you want.

During the same guidelines we will discuss about advantages, risks and pre-requisites for each update operation that will be detailed. So, this guide will be divided in separate sections that will explain certain update operations. Therefore, read all the lines before choosing to apply an update and make sure that you follow the steps that will be described; otherwise you can easily end up in soft bricking your Nokia 8.

How to Apply an OTA

An OTA is the official Android roll out that can be automatically received and applied on your Nokia 8. We are talking about the ‘over the air’ update which is coming in form of a dedicated Android notification. This update is pushed by your OEM and by your carrier and usually comes out gradually, in phases and for limited markets only.

Shortly, not all the Nokia 8 users will receive certain OTAs in the same time. Additionally, by default, an OTA can be received and also applied only if your smartphone is running on stock / official Android OS and only if root access, or other similar tweaking processes, isn’t ensured. Otherwise, you need to learn how to manually install the full firmware package (see the next section of this tutorial).

Flashing an OTA is the official update operation that can be completed without problems. You don’t have to use third party apps and you won’t have to worry about your phone’s warranty. Also, your personal data, info, accounts and files will remain safe and secured all the time – a backup is not required but you should do it anyway (that’s the only way in which you can still avoid unpleasant situations that might occur)

Now, as mentioned the OTAs are offered gradually so you might not receive it right away. But, if you know that an OTA is available for your Nokia 8, you can try to force it down by following:

  1. Power on your smartphone.
  2. Tap on Menu and go to Settings.
  3. Access About Phone and pick up Software version.
  4. There you should be able to access a search engine. Use it and initiate a software scan.
  5. If an OTA is available you will be prompted with the notification.
  6. Before resuming the update process enable a Wi-Fi connection and also charge your Nokia 8 if the power left is currently lower than 50%.
  7. And from this point just follow on-screen prompts and complete the update operation.

The same OTA, if it can be downloaded on your computer, can be installed manually through recovery mode. All you have to do is to access recovery mode on your Nokia 8 and from there select “install zip from SD card” followed by “choose zip from SD card” and just resume the flashing process.

Through recovery you can also adb sideload the new update package. Here is how you can complete this particular operation:

  1. A computer is required; there the Nokia 8 drivers must be installed and the Android SDK toolkit set up – learn how to install Android SDK on Windows or how to set up ADB on MAC OS X / Linux.
  2. Download the OTA package on your computer.
  3. Rename the update file into ‘update.zip’ and then place this package inside the Android SDK folder.
  4. Reboot recovery mode on your Nokia 8 and from there select ‘apply sideload from fastboot’.
  5. Connect your handset with your computer via USB cable.
  6. On your computer access the Android SDK folder and from there open a cmd window: press and hold the Shift keyboard key and while doing so right-click on any blank space and select ‘open command prompt window here’.
  7. In this cmd window enter: adb sideload update.zip.
  8. That should be all; your Nokia 8 should be automatically updated now.
  9. In the end close the cmd window, remove the USB cord and restart your smartphone.

Manually apply stock Android firmware

As mentioned, the OTA can be applied only in certain conditions. So, if you cannot use the lines from above, you can still flash the official Android firmware but only if you can use the full software package – it should be made available online.

This manual update process can be used as a downgrade procedure too, if you can use a previous built of the Android platform on your Nokia 8. And, of course, the steps from below will perfectly work on rooted systems, on unlocked bootloader or on any other tweaked devices.

Do note that manually installing the firmware package will restore your Nokia 8 back to its initial state. So, you will manage to revoke root access, to relock the bootloader, to reinstall bloatware and to revoke any other custom operation that was previously ensured.

However, restoring your phone back to default it’s also a good idea when you experience soft related problems such as boot loops, lags, bugs, hangs, screen freeze, battery drain, heating problems, signal strength issues, total blackouts and more. Therefore, this particular update method can be used as a general troubleshooting solution that can fix the most common Android soft related problems.

A manual update operation can be applied only if you can use a computer. On this computer the Nokia 8 drivers must be flashed. On your phone you have to enable Developer Options by tapping repeatedly on Built Number. Also on your phone, you need to check the USB Debugging feature, located under “menu – > settings – > developer options”.

Just like the OTA update, this process is also official and supported by your OEM. Once more, the warranty of your phone won’t get void so you have nothing to worry about. Now, even though your data should remain protected all the time, during the flash process your files might get corrupted. Therefore, making a backup is now recommended – on the Nokia 8 you can backup everything you want easily, by: syncing your files with your Google Account, using cloud storage platforms pre-loaded on your device or downloading and using backup and restore apps from Google Play.

Check the power that’s left on your handset; if the power is too low (lower than 50%) plug in the charger before doing anything else. If not, your Nokia 8 can get turned off right in the middle of the update operation situation during which various malfunctions can be caused within the Android core system.

Here is how you can flash the full firmware package on your device:

  1. On the computer that’s used download and install SP Flash Tool. You can get this toolkit from this page.
  2. Download the stock Android firmware file for your Nokia 8. You can get the update package from Nokia’s official website or from any other source you prefer.
  3. Now, run the flashing program on your computer.
  4. From the main Flash Tool window click on the Download field.
  5. You now have to reboot bootloader mode on your Nokia 8.
  6. Connect your smartphone with your computer with the help of the USB cable.
  7. Resume on-screen prompts in order to complete the flashing process.
  8. When done, remove the USB cable, close SP Flash Tool and reboot your Nokia 8.
  9. Done.

Install a custom ROM software

If you want to choose how to customize, optimize and personalize the Android system that powers your Nokia 8, you need to replace the stock firmware with a custom ROM. A custom ROM is a free aftermarket distribution of official Android OS and brings both stock / default features and custom apps and capabilities which cannot be found on the official Android platform.

The custom ROM is not developed by Nokia or by Google. Third party devs and behind such updates so all the credits should go to them. That’s why, the update process will be an unofficial one. Shortly, now the warranty of your Nokia 8 will get lost and you cannot do anything in that respect.

You should be careful when choosing a new custom firmware as if the system is not fully stable you can end up in using a platform with bugs, lags, hangs and with other similar software related problems.

That’s why you need to make a Nandroid backup before doing anything else. This dedicated backup will save Android system files so afterwards you can use the Nandroid backup package in order to go back to stock Android OS. And along with this backup process you should also save everything else from your phone – contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and so on. You should make a general backup because during the update process you will have to make a hard reset – the hard reset operation will wipe everything from your Nokia 8.

You also have to root your Nokia 8. An unlocked Android software is required as otherwise the stock Android OS cannot be replaced with a custom ROM. Additionally, a custom recovery image should be installed on your phone – the custom ROM is offered in form of a .zip file which can be added only through a custom recovery platform such as CWM or TWRP recovery.

Good; now since we are discussing about a manual update operation you should take care of some pre-requisites (the ones that were already explained during the previous section of this tutorial): make sure a computer can be used; your phone and its USB cable are required too; on your smartphone Developer Options must be enabled and USB Debugging feature must be checked; and you should charge your Nokia 8 before starting the steps from below if the power left is currently lower than 50%.

  1. Download the custom ROM package compatible with your Nokia 8 from any source you prefer – the xda-developers.com database might be the best source from where to choose your next custom update.
  2. Optional: if required also download Google Apps – if this package is not included in the firmware file.
  3. Save these files on your computer; if possible on desktop.
  4. Then, power off your Nokia 8 and reach recovery. From recovery wipe everything by selecting “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
  5. Reboot your smartphone and connect it with your computer via USB cable.
  6. From your computer transfer the downloaded files on your smartphone and when that’s done, unplug the USB cord.
  7. Reboot recovery mode on your Nokia 8 once more.
  8. This time, from recovery tap on Install, pick the custom update package and swipe in order to begin the flashing process.
  9. Repeat the last step and install Google Apps if that’s required.
  10. In the end, go back to main menu of recovery; pick “reboot system now”.
  11. That should be all.
