After some months i want to explain how to pass from hydrogenOS to OxygenOS and vice versa.
The first thing you need it's the stock rom, you can find here:

XDA Thread
Official OnePlus site (OxygenOS)
Official HydrogenOS site

You have to make sure that the version you are installing is more recent than the one you have on your mobile phone or the process will stop giving you an error, this is because oneplus has blocked the downgrade of the rom (You can also install the same version of the rom ).

At this moment you need to:
Push the stock rom on your internal storage ( in the main folder )
Go in settings/System/System updates/Setting icon on the top right/Local upgrade
Now you should select the stock rom you want to install and then need to click on "Install now"
You need only to wait the process finish to reboot your phone.
After rebooted you need to restore your phone, you can do it through stock recovery or better from Settings/System/Reset Options/Erase All Data (I suggest you include "Erase internal storage").
Now your phone is officially rebranded.

I made a video to explain how to make this local update:

What are you trying to do? Which method?
I have a oneplus 6T
i'm trying to go from HydrogenOS to OxygenOS using the zip i downloaded from OnePlus site. I tried to flash the zip with updater option you have on the phone but it told me that the zip i'm trying to flash is older than phone version installed. i tried to flash it in recovery but i don't have options to do that. Some guys tried to flash it via the download tool but i don't know if the successed. (I didn't unlock bootloader yet)
(ho visto che sei italiano, se hai telegram potresti darmi una mano a cambiare rom da lì, in modo da avere una comunicazione più veloce? sempre se hai voglia)

Hello. I have a question: I downloaded Oxygen OS 10.0.9 from a XDA Developers link and installed it via local update on a brand new OnePlus 7T HD1900 to flash out the Hydrogen OS 10.0.7 (fresh out of the box) . The device took it successfully without the "downgrading is not allowed" error and I did a reboot after (as the phone prompted after each local update). The reboot time is taking forever (running at about 35 minutes now as of this typing), stuck on the OnePlus circling animation. Is this normal? I'm so nervous right now, I might have bricked my wife's surprise birthday gift. Can you please help? Thank you very much in advance!

Stuck on boot screen means boot loop. You've bricked your phone.

    Yes. The beta worked. Does it still update to the next one or do I have to download the next update manually?
    Once you are on beta you will receive beta updates .
