Instructions to Install OxygenOS 5.0 Update on OnePlus 3/3T

Below, we will be laying down two different methods that you could use to install OxygenOS 5.0 update, depending upon your device’s current state. To be more clear on which method to choose, have a look at the pointers below.

  • Previous Stable (OOS 4.5.1) or Current Open Beta (Open Beta 27/18) -> Method 1
  • Custom ROM with TWRP -> Method 2

Method 1: Using Local Upgrade

The easiest way to install OxygenOS 5.0 update is by using the ‘Local upgrade’ option in the Settings. However, this would require that your OnePlus 3/3T is running the previous Stable OOS build.

[Note for Open Beta Users] – In case the device doesn’t work as intended after the update, then perform a Factory Reset from the Settings.

  1. Download the full ROM package for your device.
  2. Connect your device to the PC and enable File Transfer mode.
  3. Copy the ROM zip file to the root (Outside all the folders) of the internal storage.
  4. Once the file has been transferred, disconnect the device.
  5. Now, go to Settings -> System updates.
  6. In the update window, tap on the 3-dot overflow button on the top-right.

    • Press and hold the Volume Down + Power button simultaneously.
    • Release the keys as soon as the OnePlus logo appears.

  6. Go to Wipe -> Advanced Wipe and select the following options on the screen – Dalvik/ART Cache, System, Data, and Cache.

  9. Navigate to the internal storage and select the ROM zip package. Finally, swipe the ‘Swipe to confirm Flash’ button to install the OxygenOS 5.0 update on your phone.
