    Hello all,

    where can I get the OnePlus 7T with Oxygen OS pre-installed in China?

    Apparently it is unavailable in the online store as they only sell the Hydrogen OS version.

    thanks in advance!

    its very easy

    go to oneplus site

    download oxygen os rom for your model

    put that in your phone storage

    go to updated menu, go to settings, click on local update, click on the file you downloaded and just put in your mobile

    it will install oxygen os into your mobile

    Not so easy at the moment as you will get the "Local upgrade. The version of your selected package is lower than that of the current system. To avoid booting failure, downgrading is not allowed." Apparently HydrogenOS is one step ahead of OxygenOS? Either way, it doesn't work. Probably need to wait for some updates to Oxygen while NOT updating Hydrogen.

    In China, you can only find OnePlus devices running HydrogenOS, which is China only ROM, complying with restrictions about Google services (among other details).
    You can manually flash any ROM you want, using a computer. ADB and FASTBOOT are easier to use than most people imagine. However, Chinese OnePlus devices may differ from other parts of the world's on some details, like frequencies, so you'd better check if it will be OK for you once out of China.

    Thanks for the idea. Is the zip file downloadable from the OnePlus support site flashable?

    Sorry, I'm a little slow with this stuff... appreciate the help though. I downloaded the full 2.5GB zip from here, installed ADB on my Windows 10 machine, and enabled OEM debugging etc on my phone. I successfully connect to the phone and can root it, but I can't figure out how to flash the Oxygen OS zip file...

    You need to Turn on advance booting options from Developer options. Now, I'm good if you like to go to Recovery by pressing Volume and Power button combination. But the first option is way easier than hard pressing the Buttons.

    As you have completed step 1,2 and 3

    1) Download ROM
    2) Download adb
    3) Adb driver installed

    start from here...

    4) Put the file of the oxygenOs in adb folder , you can see this folder in C as it is default ( assuming you kept it default)
    5) Start the smartphone in recovery mode , now click install from adb
    6) From windows positioning on C folder , and start new session of prompt from adb folder ( you can do this, click shift on keyboard and while right click on adb folder , and you can see the option start new prompt command from folder)
    7) from the prompt you can put the command "adb devices" , for be sure the computer see your devices.
    8) Now you can install your rom , put the command "adb sideload filename.zip"

    assuming you have knowledge of issues that can be encountered, I am not enlisting them over here.

    Of course, if you have important data on your device, be sure to save them on another storage first.

    And if you're lucky enough not to run Windows, but a true OS on your computer, simply run a terminal window. On MacOS, all ADB and FASTBOOT commands must start with ./
    e.g.: ./fastboot devices

    Hi, I bought OnePlus 7t in China and it has Hydrogen OS installed and I can’t update it on Oxygen OS locally because the Chinese firmware version is higher than the available Oxygen OS.
    I'm ready to wait for the global firmware update, but which version is right? Version 10.0.4 will be available in a few days. Will it update Hydrogen 10.0.1?

    There's no updating from HOS to OOS as those are 2 different ROMs. You'll need to manually flash OOS. Follow a tutorial you'll find on the forums.

    Earlier I upgrated HOS to OOS locally, on 5t and 6t. But now HOS version higher than OOS.
