    Hello
    I just got my OnePlus 7T in China running Hydrogen OS. Has anyone in the same boat succesfully got their phone onto Oxygen OS? The local upgrade feature does not work anymore for upgrading from Hydrogen to Oxygen OS.
    Can I just use ADB and fastboot flash the latest Oxygen OS from the support site? Is that zip flashable?
    Thanks!

    You should be able to boot into recovery to install Oxygen OS, unless they changed that around.

    There's probably instructions on the forum if you search for them.

    I can boot into recovery, but there are no useful options there for installing or flashing anything.

    I contacted OnePlus live support and they were less than helpful:

    Connect to a computer and flash using adb and fastboot commands.
    You'll find tutorials on the forums.

    Hi,
    Did you manage to reflash?
    I'm case you did not, I would suggest to use the standard updater tool inside and select local install. Worked for me to flash Swedish version onto my hydrogen 7T
