Oreo Open Beta 1 for OnePlus 5T started | Download OxygenOS 5.0 and H2OS beta

Update: The Open Beta 1 for OnePlus 5T started with Oxygen OS 5.0 build as well as Hydrogen OS H2OS. Downloads available below. Today is a remarkable day for the manufacturer OnePlus and its customers. We saw OnePlus 5T Oxygen OS 4.7.6, new Open Beta 29 for OnePlus 3, and Beta 20 for OnePlus 3T. Now, the flagship OnePlus 5T is received its first ever Open Beta Program update starting with Hydrogen OS, a.k.a, H2OS ROM. The 5T can now officially be updated to Android 8.0 Oreo with the first roll out of Open Beta 1 via H2OS firmware update.

Since the H2OS beta started today, we may most likely see Oxygen OS Open Beta 1 for the OnePlus 5T as soon as tomorrow. The new update brings all the Oreo goodies like Picture-In-Picture, added new Auto-Fill for passwords, smart text selection for texts, etc. It also features the latest December 2017 Security Patch. This is the same update log that came with OnePlus 5’s first beta program.

H2OS as we know, is an alternative ROM for the OnePlus Chinese variants. However, they work flawlessly on the international or global variants as well. The only thing missing with H2OS firmware is the Google Play Services. But you can manually install Gapps for Oreo update.

The OnePlus 5 successfully received Oxygen OS 5.0 right after the Open Beta 2. This also brings the latest Android 8.0 Oreo to OnePlus 5. Now its time for the OnePlus 5T. Download and install the full Oreo stock firmware for OnePlus 5T from below.
