Install Oxygen OS on my OnePlus 6 bought in China

[FrostLDeacon]

Hi Guys,

I asked my colleague to buy me a OnePlus 6 from China. I just got the phone but realized that it's running on Hydrogen OS.
Is there any easy step-by-step guide on how to uninstall Hydrogen OS and replacing it with Oxygen OS?

To add to this, I have no experience in rooting any phone before or such technical stuff, so I would really appreciate if the guide is a "for Dummies" kind of guide.

Details: It's 8GB, 128GB version. I live in Sweden.

Many Thanks in advance!

First, download (latest) oxygen rom from this forum and copy the rom file into your phone
Then, in system, select 'setting'->'system update', then hit the setting button on the top right corner, select 'local update' and select the rom file
wait for it to finish and it's good to go

Of course, it's the same hardware (only change the FD-C band for 3G/4G). Flash via fastboot or TWRP the full .zip

Thanks a lot!

As mentioned, I'm really not very technical and would appreciate a more thourough explanation on what steps I need to take.
For instance, a link to the latest Oxygen OS would be very helpfull. Where exactly should I copy the file in the phone? Maybe it doens't matter? So it will just "override" the Hydrogen OS and no need for anything else? I mean, there will not be double OS's on the phone?

Sorry for all the questions, but I'm just very nervous about this.

Thanks!

Thanks bro, but I didn't understand a word of what you said. I need a step-by-step guide to manage this.

In the guides section there is a posting "Stock Fastboot Roms for the OnePlus 6". Step by step instructions and download links are there.

Sorry for the late reply.

First, download (latest) full oxygen rom from https://xdaforums.com/showpost.php?p=76596831&postcount=2
it's a .zip file, you should copy the rom file into your phone
Then, in android system (not recovery/bootloader), go to 'settings'(of system)->'system updates', this is where h2os/o2os manages otas
then hit the setting button (looks like a gearwheel) on the top right corner, select 'local update' and select the full oxygen rom file
wait for it to finish, reboot and it's good to go

Honestly, you should find a friend who has basic technical skills with Android and Flashing ROMS.

Making a mistake without understanding the foundational skills required, might cause your phone to be unusable. Some assume everyone has the skills needed and no offense, but you sound like you may not have the technical skills to be trying to switch from HOS to OOS. Trust me, if you're not sure, don't mess with it.

This procedure still valid today? THx!!!

BTW, heard google pay (not play) does not work after flashing international rom, is that true?

Sorry, I just don't have the condition to test that. However, I think in this way you can get your phone on real O2OS, and if you apply another version of full OTA update of O2OS (like 9.0.2) the problem may be solved.

A6000 which is for the Asian markets and A6003 which is for US and EU.

Hello showgood163,

I've just bought Oneplus 6T in China.
Is this procedure will also work on Oneplus 6T ? I've found a youtube video telling that after installing the Oxygen OS, we must do factory reset. Is it really needed to do a factory reset?

In my case, my phone is brand new out of the box, and I want to change from Hydrogen OS to Oxygen OS. Should I use the local update method or installing it from Recovery Mode (by pressing power button and volume down button.

Thanks in advance!

I don't have an Oneplus 6t so I can't test on that for now.
However, the rom you download from the official site is not compatible with 3rd party recovery, and there's no `install from` option in the official recovery.
