    Hi guys, Im thinking about gettung the new OP8 pro but Im in China right now, so I will receive the device with Hydrogen OS intead of Oxygen OS, I changed my OP7 pro downloading Oxygen OS to the root of the cell and then doing a local upgrade, after that a factory reset and so far so good, does anyone knows if the same procedure can be applied to the OP8 pro? Thanks

    think you can do this but you have to go for a factory reset.

    I'm unable to do a local upgrade because it says unable to downgrade, downgrading is not allowed. Any ideas how to override this issue?

    The system will not allow the installation of an OS version, older than the currently installed version. No way to get around this. Its all about the build date, you may have to wait until a version of OOS is released that is newer than the currently installed HOS version. Its also possible that the OOS version you downloaded is not the most recent.

    I downloaded the oxygen os from the one plus website so should be the newest version. So there's no way to override the hydrogen with oxygen?

    Hi! If "rom" means the latest update available in the OP website (support/software upgrade) it does not work like that. The problem is the same as what the beginning of the thread says (not possible to downgrade)

    still no answer? I bought my OP 8t (with H2) in the beginning of December and still cannot use it because still there isn't a newer O2 version. What an awful user experience.

    For the best user experience (and 4G/5G band coverage) you should buy a phone meant for your region.
