OnePlus team has recently started rolling out the Nougat based OxygenOS 4.0.1 over-the-air (OTA) update for OnePlus 3 devices in a phased manner. Consequently, some OnePlus 3 users may still be waiting for the rollout of the new update in their country or region while others could have missed the OTA update notification due to a modified or rooted firmware installed on their handset.
All those users who failed to receive the OxygenOS 4.0.1 update via OTA can now download the same manually, using the step-by-step guide posted below.
Prerequisites
- Ensure that the USB drivers for the OnePlus 3 are installed on the computer.
- Keep your phone's original USB cable handy with you.
- Make sure that you have Developer Options enabled on your handset by navigating to Settings menu. Just tap 7 times on the build number by going to Settings > About Phone and the Developer Options should now be visible in the Settings menu.
- You can now enable USB Debugging mode via menu > Settings > Developer Options.
- Verify that your phone's bootloader is unlocked, but not rooted.
