How to install Android Oreo with the April security patch on the Samsung Galaxy Note 8

Even though Android Oreo for the Qualcomm Snapdragon Samsung Galaxy Note 8 was just released for AT&T, Verizon, and Sprint, the April security patch version of it has already been released onto Samsung.Firmware.Science.

This update is for the Snapdragon Samsung Galaxy Note 8. The update is not certified yet, so you will need to follow this guide to get the Google Apps working. This build includes the April security patch and the typical array of Android Oreo features, such as notification channels, picture-in-picture mode, notification snoozing, background app optimizations, and more. As you would expect, there are plenty of Samsung-specific changes with Samsung Experience 9.0 as well. You can follow the guide below to install it yourself.

How to Update Galaxy Note 8 to Android Oreo:

1. Check your phone's model number to see if its N950U.
2. Before you start here you need to follow this guide to install Android Oreo on build number N950USQU3CRC2.
3. You will need to download 2 OTA files, CRC2 to CRC4 and CRC4 to CRC5. I recommend downloading one and renaming it then downloading the other, after doing that transfer them to your sd card
4. After downloading those files and making sure you are on update version N950USQU3CRC2, go to recovery by powering off your phone and holding volume down + power + Bixby button.
5. If you have an SD card, select "apply update from SD card." You can select this by using your volume rockers to navigate and the power button to select. After selecting the option, find the update for CRC2 to CRC4 that you renamed and select it, apply the update and let the phone reboot.
6. Once the CRC4 update is applied, reboot to recovery and do the same as above with the CRC4 to CRC5 update. Once you do this, your phone will reboot and you will be good.
7. If you don't have an SD Card, you can use adb to install it. Boot into recovery by using volume down + power + Bixby and select "apply update from SD card" then you can use the adb command adb sideload CRC2 to CRC4.zip.
8. Once the CRC4 update is applied, reboot to recovery and do the same as above with the CRC4 to CRC5 update. Once you do this, your phone will reboot and you will be good.
