Warning:

Following anything in this guide will erase and reset your phone completely. It is highly recommended that you have backups of all your important data before proceeding, and that you also remove your Google account from your phone. This guide is only for the Snapdragon S8 Plus variants. Flashing to stock firmware from unlocked firmware will require you to follow the Carrier Switching section of this guide, which also means you’ll need to follow the Flashing Standard Firmware section, unless the CSC code of your carrier is currently active. If you need to double check this, go into Recovery Mode by holding Power + Bixby + Volume Up, and once it transitions from a blue to black screen, you’ll see your active CSC code on the bottom. If your CSC code is already matching to your carrier’s, you only need to follow the How to Flash Standard Firmware section. But before doing anything from this guide, you must follow the Prerequisites section.

How to Flash Unlocked Firmware

Please be aware that the unlocked firmware does not unlock your phone for use with other carriers. It simply removes carrier bloatware – this may have the drawback of certain carrier features, like Wi-Fi Calling or VoLTE not working with the unlocked firmware.
