Hello.
I found a good deal on a 7T 256+8 CN version, which is cheaper than getting it directly from OnePlus european store, where they only sell more expensive 128+8.
Few questions:
1. This is my first OP device, could anyone please tell me step by step how to install OxygenOS?
2. Switching between HydrogenOS and OxygenOS, do i need to lock/unlock bootloader?
3. Since the version i'm getting is CN 256GB, will the official EU OxygenOS build even work on the phone? Considering they only sell 128GB in EU. Won't it bug out?
4. After i flash OxygenOS, will it just work normally as it would with EU phone? Support OTA? No other difference in functioning?
5. Since the phone will be imported from China, will it have any IMEI issues or something hardware related? LTE bands are the same.
6. Any other things i should know about? I tried to think about all the could-be roadblocks, but any other tip is greatly appreciated.
Thanks!

Yes works normal. OTA works.

Thanks for your reply. Just so i understand, i'm not looking to root the phone nor do i want to mess with the bootloader. All i want to do once i get it is to flash stock OxygenOS, latest version and completely remove CN ROM. From other info i gathered while browsing google, OP phones are one of the only ones that allow to switch from CN to EU ROM seamlessly without messing with any commands or programs.
From what i understand, i need to enable some option in developer settings, then download EU ROM from oneplus website, then in phone settings go to update-local update and just select the downloaded EU Rom? Can you confirm if that's basically all there is to it?
Much appreciated!

NO risk if labelled POCO F3.
Global worldwide standard EURO one included.
There is a case to change version from global to EEA without losing the device warranty? 'Poco F3'
If anyone knows for sure let them write it.
Thanks!

you will have to unlock the bootloader before downgrading, I have a file ready (just run flashfile.bat) but it's ZTO, do you want me to send you the link?

Try MSM tool with "SHA" unchecked and "firehouse" checked... See if that helps.
