We have also mentioned some security tips like backing up your device for safety purpose. Please make sure to read them carefully so that you don’t get stuck in the middle of the tutorial and loss of some data. We won’t be responsible for that.

Why manual update via Odin?

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

  1. Bricked device: In case, your Galaxy Tab S5e T725 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!
