How to install May security update on the Snapdragon Galaxy S9/S9+

The Samsung Galaxy S9 and S9+ have been out for a little over a month now. Samsung and the carriers have not released an update for their phones since the day one update. Almost every Snapdragon Galaxy S9 and S9+ are still running the February security patch from launch.

The updates in this guide are for the Snapdragon variants of the Galaxy S9 and S9+. The Exynos variants of the phone have already received the March security update, but nothing past that. The update has not been certified in the Play Store and doesn't pass SafteyNet, but while running this update on my own device, Google Pay and all the Google apps are still working. This build includes the May security patch and bug fixes, though we do not know any specific bugs that were fixed. This update also adds Chatbots for AT&T users.

How to Update Galaxy S9 and S9+ to May security patch:

  1. Check your phone's model number to see if its G960U or G965U.
  2. You will need to download ARC6 Odin for S9 and update for S9 and the ARC6 Odin for S9+ and update for S9+.
  3. Copy the OTA file onto the SD Card on your phone. If you don't have an SD Card, you can skip this step but you will still need the OTA file on your computer. Extract the Odin firmware linked earlier. It will be in a zip format.
  4. Make sure before you continue to disable all Substratum themes on your device. You will be able to re-enable them once the update is installed.
  5. Reboot your device into download mode by powering off your device then holding the Bixby button + Volume down + power
  6. Download the Odin tool and plug in your phone to your computer. Odin is an official tool from Samsung that can flash official Samsung firmware onto Samsung Galaxy devices. In Odin on the right side, you will see 5 sections, but only 4 of those will be used.
  7. Click the BL button and navigate to your Odin firmware folder where you extracted your files, and then click the file starting with BL. Do the same for AP and CP and HOME_CSC, do not use CSC_OYN as this will wipe all data on your phone..
  8. Click start at the bottom of Odin.
  9. Wait for your device to flash and then reboot. As soon as it reboots, power off your phone again. Then, boot into recovery once more by holding down the Bixby button + Volume up + power.
  10. 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 file called "update.zip" and select it with the power button.
  11. If you don't have an SD card, select "apply update from ADB." On your computer, open a command prompt by pressing Windows key + R and typing "cmd." Once this command prompt opens up, type "adb sideload" and press enter. If you don't already have ADB set up, you can follow these quick set of instructions to get up to speed.
