    Rovnro , May 3, 2020 :
    My Oneplus 6T is running HydrogenOS 10.0.3 (equivalent to OxygenOS 10.3.2)
    I tried to install the full OxygenOS 10.3.3 package, but it gave me an error message.
    What should I do?
    Notes: Yes, installing a full package is the only way to switch to OxygenOS.

    You can't install OOS over H2OS like this since they're two different ROMs. You must do it via recovery.

    As you are switching from H2OS and OOS, I would suggest the following.

    If you can backup your phone data first. Then try the steps below.

    It is used to reset a phone, but H2OS is essentially a different os to OOS. So you will have to wipe the phone to allow GMS services install. Basically Google Mobile Services.

    This is used to unbrick a phone, but it will allow you to switch to OOS.

    Follow the instructions to use the MSMDownload Tool for Oneplus 6T.

    https://www.thecustomdroid.com/oneplus-6-6t-unbrick-guide/

    Scroll down to view the Unbrick details and downloads.

    Download and use the Android version you want TO use to unbrick the phone with for OP6T.

    Once you have the phone backup and running.

    Install OTA updates to get the most recent update.

    I don't know if I can use the method you suggested to switch to OOS 10.3.3, as:
    • I can't upgrade mine to 10.3.2 because of the OS restriction only allowing to upgrade to a higher OOS version.
    • I don't know if 10.3.3 has a decrypted version or not.

    Use the method I suggested and it will be fine. There are several options, you could use 10.3.2 then update to 10.3.3.

    Or as I said, you could also try the steps in the link you were given by your phone retailer as it is a step by step guide. Either way should work fine. If one doesn't, try the other.

    But make sure you back up all your personal data on the phone first.
