Sprint has started the Galaxy Note8 upgrade process to Android 8.0.0 Oreo this April. If you want to manually install the new update then you have to read the tutorial below.
The new Android 8.0.0 Oreo upgrade is being rolled out in stages for all users, but this will take a while before it reaches every single Galaxy Note8 user. If you are an advanced user, then you can use ODIN and the instructions below to complete the update before it arrives over-the-air in your region.
Odin 3.13.3 app is capable of installing the new official Oreo update over a custom ROM, too. You will have to Factory Reset the phone after the update is done installing. Before staring the update you need to check the following guidelines:
- use the guide only for the Sprint CDMA Samsung Galaxy Note8 phones.
- the model of your device has to be the SM 0 N950U1.
- do not attempt to update any other devices with the files found in this post.
- download the Samsung USB drivers from here, and install them on your PC.
- for the update process you will use the ODIN 3.13.3 app.
- for this tool to work with the PC and Galaxy Note8 device you need to install the above usb drivers, and to enable USB Debugging from Developer Options menu.
- if you cannot find Developer Options, then you have to enable that first.
- go to Settings> About Phone and tap seven times on the Build Number text.
- Developer Options will now be listed under Settings, open that menu and enable USB Debugging.
- Odin can flash official Android 8.0.0 update over rooted, but stock Android firmware, without losing any data files.
- any custom Recovery you might have flashed will be replaced with stock Recovery.
- Odin can be used to install the update over a custom ROM, too, but for your phone to boot after the update is done you will need to Factory Reset it, too.
- the Factory Reset steps are listed at the end of the guide.
- Factory Resetting the Galaxy Note8 Sprint will wipe clean system partition, but it won't remove any data files from internal storage.
- if your Sprint Galaxy Note 8 device runs 100% stock Android 7.x firmware, then you can continue straight to the update process and start the installation, as no data should be lost in the process.
- 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.
- read the whole post and don't skip any steps.
How to Update Galaxy Note8 Sprint to Android 8.0.0 Oreo official:
- Download Android 8.0.0 N950U1UEU3CRC1 tar.md5 archive file from here.
- After the download is done you can extract the archived contents.
Save the obtained files on your PC. You will get five tar.md5 update files, don't extract further.
- Download Odin 3.13.1 zip from here.
- make sure to grab the correct Odin 3.13.1 version, as the older one won't be able to flash Oreo OS.
- Power off the Galaxy Note8.
- Boot the Galaxy Note8 Sprint in Download Mode.
- Launch Odin exe on your PC.
Wait for Odin to detect the phone.
- if the device is not added you need to reinstall the usb drivers..
- Return to Odin and start to load the update files:
Click BL and load the BL_N950U1UEU3CRC1 tar.md5 file.
Click AP and load AP_N950U1UEU3CRC1 tar.md5 update file.
Click CP and load CP_N950U1UEU3CRC1 tar.md5 file.
Click CSC and load HOME_CSC_N950U1UEU3CRC1 tar.md5 file. Do not load the file that only contains CSC in its name without HOME, as that file will trigger the Complete Factory Reset process and you will lose all data.
- Confirm the update by clicking on START in ODIN.
- don't press any buttons until the update is done.
- When installation is done you can see the ODIN app showing the PASS alert, and the Galaxy Note8 will reboot in normal mode.
Unplug the phone from PC.
Use your default login data in order to regain control over your device.
If the FAIL message is displayed by Odin, then you have to repeat the tutorial once more. Make sure to read the whole guide and don't skip any steps if you repeat installation.
If the PASS alert is displayed by ODIN, but the Galaxy Note8 enters in a boot loop, or it gets stuck stuck at the boot animation, then you will have to Factory Reset the system partition of your phone.
The Factory Reset process is going to wipe clean the system partition, and it will force your Galaxy Note 8 to boot in normal mode with Android 8.0 Oreo stock firmware. The steps below should be used by those that have installed the new official update over a custom ROM, too.
Here's how to factory reset the device:
- power off the phone.
- boot it in Recovery Mode.
- select 'wipe data/ factory reset'.
- reboot device in normal mode and you are done.
