T-Mobile and Samsung USA have released the new and official Android 8 Oreo OTA update for all the Galaxy Note 8 users on their network.
Below you can find instructions on how to manually complete the new Oreo OS official upgrade using the Odin 3.12.3 Windows tool. These updates are normally rolled out in stages for all users and not everyone will get the new files at the same time.
The new Oreo 8.0 OS upgrade brings tons of extra goodies and improvements for your Note 8 device. Before starting the flashing process you need to check the following guidelines:
- use this post only for the Samsung Galaxy Note 8 T-Mobile USA models.
- do not attempt to update any other devices with the files found in this post.
- download Samsung USB drivers from here, install them on your PC.
- this will allow your device to connect with your PC via ODIN tool.
- for the Android 8.0 Oreo OS upgrade you will have to use ODIN.
Odin requires you to install the above usb drivers and to enable USB Debugging from Developer Options menu.
- if you cannot find Developer Options, then you will have to enable this menu first: go to Settings> About phone> Software Info and tap seven times on the Build Number text.
- return to Settings, and you should find the Developer Options.
- the new official update can be installed over rooted firmware, but you should know that root access won't survive the installation process.
- if you've flashed a custom Recovery that will also be replaced with Stock Android Recovery.
- Odin allows you to manually install the Android 8.0 update over a custom ROM, too.
- if you do this, then you will have to apply an extra Factory Reset step after the installation is done.
- the Factory Reset steps are listed at the end of the tutorial.
- the Factory Reset process is going to wipe clean the system partition, and it will remove the installed custom ROM from your device completely.
- no data will be deleted by the Factory Reset process from internal storage.
- if your phone runs 100% stock Android firmware, then you won't be losing any important data files and you can start the updating process as soon as you wish.
- check the whole post first and do not skip any steps.
- this guide has to be applied by advanced users, we cannot be blamed in case you brick the phone nor in case you lose any data files in the process.
- if you need more help completing the tutorial, then you can tell us in comments below.
How to install Android 8.0.0 Oreo Update manually for T-Mobile Galaxy Note 8 USA:
- Download the Android 8.0.0 G950U1UEU2CRB9 archive file from here.
- When the download is done you have to unhide the contents and save them on your computer.
- you will obtain several files with the tar.md5 extensions.
- don't unzip any of these files.
- Download Odin 3.12.3 zip from here.
When the download is done you
- Switch off the device.
- Boot it in Download Mode.
- Open Odin exe on your PC.
- Connect your phone to computer via usb cable.
Wait for Odin to add the device.
- if the phone is not added you need to reinstall the usb drivers.
- Go back to Odin and start loading the update files.
- Click AP button and load G950U1UEU2CRB9 tar.md5 with AP in the name.
Click BL and load the G950U1UEU2CRB9 tar.md5 with BL in the name.
Click CP and load the CP G950U1UEU2CRB9 tar.md5 file.
Click CSC and load the G950U1UEU2CRB9 file with HOME_CSC in the name. Don't load the CSC-only named file, as that one will tell ODIN to wipe clean the device.
- Press START when you're ready to begin the Android 8.0 official update for your phone.
Don't press any buttons until the update is done installing.
- After the update is done flashing you need to reboot the phone in normal mode. ODIN will show the PASS alert.
- Unplug the Note 8 device from PC and wait for first boot process to be completed.
These were all the steps you had to take in order to complete the Android 8.0 update for your Galaxy Note 8 T-Mobile USA device.
If the FAIL alert is shown by the ODIN app, then you have to repeat the whole tutorial more than once. If you repeat installation you need to make sure that you won't skip any steps and that your phone meets all requirements.
If the PASS alert is displayed by ODIN, but the Galaxy Note 8 T-Mobile USA device enters in a boot loop, or it gets stuck at the boot animation screen for more than 20 minutes without doing any loading, then you have to factory reset the device.
The Factory Reset steps below should be applied by those that have installed the Android 8.0 update official firmware over a custom ROM, too. Here's how to factory reset the device:
- power off the device.
- boot it in Recovery Mode.
- select 'wipe data/ factory reset'.
- reboot phone in normal mode and you're done.
