Samsung has released the latest Oreo update for Galaxy J7 Pro with build number UBU5BRK3. This build comes with November 2018 security patches.

Galaxy J7 Pro

A detailed step by step tutorial is given below along with the software download links for the Galaxy J7 Pro. We had also attached an article for rooting Galaxy J7 Pro on Oreo. Read ahead, and grab them all!

We will be using Odin software in order to install UBU5BRK3 Android 8.1 Oreo Stock Firmware on Galaxy J7 Pro.

Since this is an official update by Samsung, not a custom ROM, don’t expect any additional tweaks or pre-installed apps. But this build will definitely help you to bring your phone to an updated stock position.

Why manual update?

Manual installation of Samsung stock firmware is required for the following reasons:

  1. Bricked device: In case, your J7 Pro has been bricked while trying any custom ROM or mods, you can manually update your phone to recover and get back to stock position.
  2. OTA problem: If you aren’t getting direct OTA from Samsung due to carrier or region problem, you can download Samsung stock firmware and flash it to your phone using Odin tool.
  3. Rooted device: Rooting opens the window to customize your Android phone. But sometimes, this root status can break the OTA links. That’s why you might not be able to update your phone directly.
  4. Custom ROM: If you had installed any custom ROM like LineageOS, it is inevitable that there is no way to get official OTA. You need to flash the PDA and other files using Odin to get back to stock ROM.
  5. Bootloop: Facing bootloop issues due to some root apps or some Xposed modules? Manual update will help you!
