How to convert the OnePlus 6T Hydrogen to OnePlus 6T Oxygen

Or any OnePlus phones that are running OP Hydrogen to Oxygen.

Convert OnePlus Hydrogen to Oxygen OS

We recently received our OnePlus 6T here at Review Hub only to find that it’s running the Chinese Hydrogen OS. There are pros and cons to importing yourself the OnePlus 6T, the main pro being some big savings!

The downside? If you choose a mainland China OP6T, then your warranty will only cover you in mainland China.

But if you do find yourself with a OnePlus 6T and are thinking “what the heck is this Hydrogen OS that’s pre-installed? Why are there lots of Chinese apps? And how do you get the PlayStore?” Then you’re in the right place!

You can easily turn your OnePlus Hydrogen OS phone into a OnePlus Oxygen OS phone in around 5 minutes. It’s hassle-free and done via the official OnePlus website.

    • Hi James, this method doesn’t work for me and other users : when I chose “Local Upgrade > Select Package”, I have this message : “The version of your selected package is lower than of the current system. To avoid booting up failure, downgrading is not allowed” :( do you a solution ? thanks

  1. When I did the update on the 5th, it updated the Hydrogen to the latest version and then I downloaded the latest Oxygen version from Worked first time.

    Seems like there has been update on the Hydrogen OS since then.

    Maybe if you make sure automatic updates are turned off in the developer settings and then wait for Oxygen OS to update to a newer version?

    As it’s just been released I imagine it’ll only be a few weeks tops with the bug fixes / enhancements.

  2. Hi Ardi,

    We haven’t tested with the McLaren version. What version of Hydrogen were you on before the update? Did you make sure to download the McLaren version of the software from OnePlus’ website?

  3. Hi, have you tried this method with OP7 Pro? im living in China, wanna get my hands on it but I dont like Hydrogen OS, I did this to my OP6 and I would like to know if the same procedure might work with the newer phone, thanks!
