How to Update Samsung Galaxy Note8

Playing with updates is both fun and great, especially when new features, apps and capabilities are added to the default Android system. So, knowing how to complete different update operations on the new Samsung Galaxy Note8 is not really optional. As you know, by keeping your phone updated all the time you can use a stable, smooth and secured Android system. So, read all the guidelines from this tutorial if you want to learn how to successfully apply three different flashing operations.

Yes, we will discuss about three update methods that can be used on the Samsung Galaxy Note8. First of all I will show you how to apply a new OTA and how to force down a new notification that isn’t spotted on your smartphone. Then, I will teach you how to use Odin for manually installing the stock / default Android full firmware package. And, in the end I will detail the update process that’s related with custom ROMs such as Lineage OS, AOKP or Paranoid Android.

Of course, during the guidelines from below we will review everything that’s related with each update procedure: the advantages, the risks and the pre-requisites. And, in the end we will also check the actual steps that must be performed for resuming each installation procedure. The goal is to make everything crystal clear, so from this perspective you have nothing to worry about – your Samsung Galaxy Note8 will be in safe hands all the time.

Good; so let’s begin:

How to Install a new OTA

An OTA is an ‘over the air’ Android release. In this case Samsung is pushing out the new update for your Galaxy Note8 automatically. However, usually such updates are offered in stages and for limited markets only. Shortly, some users will be able to receive the Android notification sooner than others.

Additionally, an OTA can be received in form of a new notification only if your Samsung Galaxy Note8 is already running on stock Android OS and if other tweaks weren’t performed. Basically, your device shouldn’t be rooted, or installed with a custom ROM firmware if you still want to receive OTAs.

Flashing a new notification can be done without problems; all you need to do is follow on-screen prompts. Your data will remain protected all the time so a backup isn’t required in this situation. And, of course, your phone’s warranty won’t get void as you will complete an official update procedure, supported by Samsung and by Google.

Now, if an OTA is available for your device but you aren’t receiving your notification, you can try to force it down by following:

  • On your phone go to About Phone.
  • Access the Software section.
  • There a Search for Updates field should be available.
  • Use it for scanning for available updates.
  • If a new OTA is available for your device, you will be prompted with the firmware package.
  • Before resuming the flashing steps make sure you enable a Wi-Fi connection.
  • Also, charge your smartphone before doing anything else if its power is currently lower than 50%.

Another way in which you can apply the OTA is by using the stock recovery image. In this case, you will have to download the OTA file on your computer and to transfer this package on your Galaxy Note8 afterwards. Then, reboot recovery mode on your Android device and from recovery select “install zip from SD card” followed by “choose zip from SD card”; pick up the firmware file and resume the update process; when done, from main menu of recovery choose “reboot system now”.

Of course, if Android SDK can be used you can adb sideload the OTA on your Samsung Galaxy Note8. For this particular update procedure a computer is required where Android SDK must be installed – learn how to flash ADB on MAC OS X / Linux or how to set up Android SDK on Windows. Your Galaxy Note8 drivers must be running on your computer and on your phone the USB Debugging field must be enabled. Then, you need to follow:

  • Rename the OTA file that’s saved on your computer into ‘update.zip’.
  • Then, transfer this file inside the Android SDK folder.
  • Put your phone in recovery mode.
  • From recovery select ‘apply sideload from fastboot’.
  • Connect your smartphone with your computer via USB cable.
  • On your computer go to the Android SDK folder.
  • Open a command prompt window: press and hold the Shift keyboard key while right clicking on any blank space and choose ‘open command prompt window here’.
  • In the cmd window that will be displayed enter: adb sideload update.zip.
  • The firmware will be now automatically installed on your Samsung Galaxy Note8.

Use Odin for manually updating the Samsung Galaxy Note8

If your phone is rooted or tweaked in any other way, or if the OTA is not coming soon enough, you can choose to complete the update operation manually. For being able to do so, the full firmware package must be available online – you need to download this package on your computer.

Manually installing the stock / official Android OS will revoke the tweaking methods that were previously ensured: so, after applying the steps from below you will manage to revoke root access, relock the bootloader, reinstall the stock recovery image and re-flash the bloatware and the other factory apps and restrictions.

This is also an official process. Samsung KNOX won’t get tripped so you won’t lose your phone’s warranty – that can happen only when a custom ROM firmware is installed. Moreover, during the flashing process Odin will be used – this is an official program developed and released by Samsung and not by third party devs.

Since the official Android software will restore your Galaxy Note8 to its default state, you can use this particular update operation as a dedicated troubleshooting solution. Yes, now you can address the most common Android soft related problems including boot loops, lags, bugs, hangs, screen freeze, battery drain, heating problems, signal strength issues, total blackouts and who knows what else.

In this case a backup is recommended – only in rare situations your personal files can get corrupted or erased while Odin is used. But, it can happen so the best is to be precautious. Don’t worry, you can easily backup your new Samsung Galaxy Note8. In that matter you can already use built-in cloud storage platforms (added by your carrier or by Samsung itself), you can download similar software from Google Play or you can just sync your data and your files with your Google account.

Make sure that a computer can be used as this is a manual process. On this computer install the Galaxy Note8 drivers – you can use the Samsung KIES toolkit in that respect. Moreover, on your device enable Developer Options by tapping repeatedly (for 7 or 10 times) on Built Number and afterwards check the USB Debugging option located under Menu – > Settings – > Developer Options.

It’s more than recommended to charge your Galaxy Note8 before using Odin for flashing the update package. Otherwise, you can end up in soft bricking your handset, so be careful and try not to mess things up. Finally, follow:

  1. Download the stock Android firmware for your Samsung Galaxy Note8 – you can get this package from sammobile.com (just use their firmware database from here).
  2. Download Odin.
  3. Install Odin on your computer and then run this program.
  4. Power off your smartphone and wait a few moments while the shut down is completed. Afterwards, reboot download mode on your Galaxy Note8.
  5. Connect your phone with your computer with the help of the USB cable.
  6. On Odin the ‘added’ message will be displayed; the ID:COM field will be turned yellow or blue – if not, reinstall your phone’s drivers and then retry.
  7. From Odin click on the AP field and pick the Android update file. Make sure the Re Partition and Auto Reboot options aren’t enabled.
  8. Click on Start and wait while the software is flashed through Odin.
  9. When done, on the program you will get the ‘pass’ message while the ID:COM field will be turned green.
  10. Close Odin, unplug the USB cord and reboot your Samsung Galaxy Note8.
  11. That’s all.

Install a custom ROM firmware

If you don’t want to use the default Android software, you can try a custom ROM firmware instead. This is also the best way in which you can tweak your Galaxy Note8 for unleashing the true potential of your Android smartphone.

With a custom ROM flashed your phone will run smoother than ever. Additionally, you will be able to customize, optimize and personalize everything else. And, of course, the ROMs will not be based on the default Samsung UX. So, everything will be faster than before not to mention that you can choose a pure-like Android experience.

Anyway, the overall idea is that a custom ROM is highly customizable and that through the same software you can improve the Galaxy Note8 performance. But, it will be important to choose a fully stable software – some ROMs are still under development stage so if you want to choose a platform that can be used on a daily basis make sure you get a fully functional OS.

A custom ROM is a free aftermarket distribution of Android OS. It is developed by third party devs and not by your OEM. That’s making the update process unofficial. And, as already outlined before now Samsung KNOX will be tripped, meaning that you will lose your phone’s warranty. Unfortunately, due to same reasons you might not be able to use some of the default Samsung apps after completing the update process.

A backup is no longer optional. A custom ROM can be flashed only after a hard reset is initiated and completed. Thus, without saving your personal files first, you will lose everything that was not there from day one. Shortly, take your time and save your contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, the EFS folder, IMEI / NVRAM data and so on.

A Nandroid backup is also a good idea. This particular backup operation will save Android files so if a downgrade operation will be afterwards requaired, you can just use the Nandroid backup package.

You can flash a custom ROM only if your Samsung Galaxy Note8 is rooted – thus, an unlocked Android system is requaired for this update operation. Moreover, a custom recovery image must be installed on your handset – therefore, learn how to install TWRP recovery on the Galaxy Note8.

A computer is required too. Your Note8 and its USB cable will be used along with your computer so the USB Debugging field must be checked on your phone – just as explained during the previous section of this step by step guide. Moreover, don’t forget to charge your smartphone before initiating the custom ROM installation process – as always, it’s recommended to plug in the charger if the power left is lower than 50%. Perfect; now you can begin the actual flashing steps:

  1. Download the custom ROM firmware package for your Samsung Galaxy Note8 – you can choose any software you prefer (on xda-developers.com you can find different update opportunities for your device – check this page in that respect).
  2. Optional: if Google apps aren’t included in the update package you will have to flash it separately; so, if required download Google Apps.
  3. Save the downloaded files on computer first.
  4. Switch off your phone and afterwards go to recovery mode.
  5. From recovery make a full wipe by choosing “wipe data factory reset”, “wipe cache partition” and “wipe dalvik cache”.
  6. Return to main menu of recovery and choose Reboot.
  7. Connect your Galaxy Note8 with your computer with the help of the USB cable.
  8. Transfer the downloaded files from desktop and place them on your smartphone.
  9. Unplug the USB cable and go back to recovery when done.
  10. From recovery tap on Install and load the custom ROM file.
  11. Swipe and resume the flashing process.
  12. Optional: repeat the last two steps and install Google Apps.
  13. In the end, go to main menu of recovery and pick “reboot system now”.
  14. Done.
