Ver Open Beta 21 (2018-01-16)

Please read the following instructions carefully before flashing your device. Flashing may lead to loss of data and damaged hardware if not done properly. Please contact our customer support if you feel uncomfortable performing the steps below.

We highly recommend backing up all your important personal data before continuing, even in cases where a data wipe is not needed.

Instructions assume you are already on OxygenOS and using the original OnePlus 3T Oxygen Recovery. We have not tested the instructions on all other alternative ROMs, but we have provided basic steps for flashing with TWRP. Please contact our customer support if you have any doubts.

** We cannot guarantee results on rooted devices.

Flash Instructions

  • Download the software build for your device at the bottom of this page.

  • Plug your phone into your computer and copy the downloaded .zip to your phone’s storage. If you’re using a Mac, you can install Android File Transfer for this operation.

  • After the .zip file is copied to your phone, reboot your phone into recovery mode. To do this, shut down your device and turn it back on while holding the power and volume down buttons simultaneously.

  • Choose "Install from internal storage/Install from local", find your .zip file and click on "Install" to confirm.
  • Wait a while, your phone should now update to the selected build and reboot automatically to take you into OxygenOS.
