Chinese OnePlus 7 Pro- get Google, flash other ROM

I live in China so currently I can only buy this phone customized for China- no Google apps and only some local crappy app stores.
I know it's possible to install Google services/store etc. on Chinese phones, but would it be possible to just flash some stock "Western" ROM on it?
Are there any stock ROMs from OnePlus available for international versions?
How can I tell if the phone I'd be buying here is "flashable"- how can I check it at the store ?
There are all 3 versions available here (6/8/12GB ram)

Chinese version uses hytrogen OS, you can try flash oxygen OS(stock os on international version)through "local upgrade" .
Some personal experience：
I bought Chinese version too and I directly flashed zip in this thread through local upgrade, the OS changed to Oxygen OS as expected but Google play store somehow wasn't installed, so I factory reseted my phone, then everything works fine now.
Note: Chinese version got a system update after it was released if you performed that upgrade you may not able to flash oxygen os because version number(9.5.4) is higher on hytrogen os than on oxygen os(9.5.3).
Note 2: This thread provide 9.5.4 oxygen os now so if you already performed upgrade on hytrogen os you can try flash 9.5.4 oxgyen os.

Hi, I'd like to hop on this thread to ask a similar question.
So right now I'm in China and will stay for a few weeks. I've been wanting to get my habds on a 7 pro since I learned about it, and I'll be residing in S.Korea for the foreseeable future.
I have an option to purchase the device from the US official website and have an agency deliver it to me at my Korean address (I'm assuming the US version retails as the global version GM1917 I believe?). All in all it'll cost around $790.
Or I can purchase the cheaper, chinese version while I'm here and install the Oxygen OS on it as I'm told it's a rather simple procedure for Oneplus phones. I've never tried any sort of unlocking/bootloader/flash/custom rom stuff so I'm not entirely familiar with all this but it seems doable if i tread carefully.
The question that stands however, is whether or not there will be any difference at all between the two. I believe the Chinese model is named GM1910, I'm assuming there are some hardware differences like band support, but then again I can't find a clear answer on this. I've also heard that flashing the OOS might mean it wont be google play digital certified (not entirely sure if i got the name right or what it does) and I might encounter widevine issues. But then again I've seen people mention the hardware is the same so as long as I convert the OS it should work like a breeze as if it was the global version.
I'd appreciate any help and guidance in this matter. Also by flashing the OS would that mean I'd have to manually apply OTA patches whenever they're released? I'm not too concerned on warranty issues but if you guys have anything crucial I should keep in mind about it I'd be grateful for the help.
Thanks in advance.

All version sold in china is "flashable", just pick up the specs/color you prefered.
For the switching the system from HOS(Chinese version) to OOS(global version), it's simple:
1. flash the newest Oxygen OS(GM21AA, for global version) through system update;
2. reboot to recovery;
3. wipe all data of your phone
Done.

Widevine downgrading(L1 -> L3) happened when you unlock the bootloader. If you just get an chinese version OP7P, switching system from HOS to OOS, it's ok to do it through system update, while maintaining the widevine level.
After switching to OOS 9.5.3, my chinese version OP7P works pretty fine with all google service(except google pay, no environment to test it)

I'm not sure if there are any hardware difference between Chinese model and other model, but I'm sure Google play is still certified on Chinese model after flashing OOS. Widevine level won't change as long as you don't unlock bootloader and you won't need to unlock bootloader if you only want to flash OOS.
I used to have a Chinese version OnePlus 5, I flashed OOS on it and everything works pretty well for two years, OTA always works. I assume everything is the same on OnePlus 7 pro.

Hey, thanks for the reply! for some reason I can't quote the edited latter part of your post.
It's great to know its as simple as you said. But like I mentioned I'm quite new to all this so I hope you're fine that your answer also raised some questions for me.
So if there's no influence on widevine, why would people go the extra effort to unlock the bootloader? Isn't it primarily to flash a fresh ROM which would mean the end goal is basically the same is it not? Would my OS converted phone be any different to that of a bootloader unlocked one in regards to performing identical as a global version 7 pro?
Thanks so much for the help!

People unlock bootloader because they want to root their phone or flash third-party ROM. Bootloader has to be unlocked if you want to flash anything other than stock ROM or other stock things.

Thanks you are amazing. I think I can safely go with the Chonese version. One last question though, would tweaking for VoLTE require any rooting?

Glad I can help.
If you're in China, I don't think you need to tweak anything to use VoLTE no matter which OS you're using (Hytrogen OS or Oxygen OS), there are three main telecom operators in China: CMCC, China Net and China Unicom.
CMCC already support VoLTE so if you're using CMCC's service your phone will enable VoLTE automatically once you plug in the SIM card and detected signal.
China Net added support for VoLTE very recently, so VoLTE should be automatically enabled too once you plug in a China Net's SIM card, but I'm not sure about this because I'm not using any China Net's service.
China Unicom does not support VoLTE until June 1st 2019, you won't be able to use VoLTE till then in any method if you are using China Unicom's service (Google Fi and some international roaming use China Unicom's service so no VoLTE for Google Fi and those roaming yet)
Dual VoLTE with dual SIM should work too, I'm using CMCC and China Unicom dual sim and VoLTE icon on my status bar have a "1" next to it(VoLTE1), I think there will be a VoLTE2 after China Unicom support VoLTE.
I know little about these Telecom operators things outside of China, but I think Oxygen OS support most country's VoLTE service as long as their Telecom operators support VoLTE.

I'm new here, my op7 pro is on the way to me, I'm in China too, so I should unbox it, do not upgrade, download the oxygen os and flash it directly? Than I'll get a "global version" op 7 pro, will it work?

Hydrogen to Oxygen, breathe (google) freedom but what about custom ROMS?

I received this morning my device, living in China i could get my hands only on the GM1910 version.
first thing i did was download the latest Global Oxygen OTA from the oneplus website and do a local update to switch to Oxygen firmware from Hydrogen: Success
unlock bootloader: success
install TWRP: success
install Magisk: success
when i went into the settings/about phone page i noticed that my phone model is still GM1910, this is my first time to use a OP device so i don"t know how to feel about it or what that really means, I would like to switch to a custom ROM and the minimum requirement usually is to have a matching stock firmware version, doesn't mention the region.
my only question is: can the phone model name cause any trouble or is it just a "label" and is not going to influence in any way?

I have the same variant as you, out here in Canada. I didn't find out it was the Chinese version after I had it for a few days. It hasn't had any impact on my experience whatsoever. I rooted, I flashed stuff. I even flashed Global firmware versions a few times. No issues. Hope this helps. ?

thank you for your insight,
i couldn't not notice because i had a bunch of useless (for me i guess...) chinese apps preloaded and no Gapps, maybe you received it with another version of the firmware,
but it kind of reinforce my opinion that the model name doesn't matter in this case, being the "unlocked" part the most important.
I am also running the global version of the firmware now, seems without any problems, but i will need some time to confirm that and try to flash a custom ROM or kernel in few days

Huawei Assistant APK (Chinese) wanted

For some Reason my original Chinese ROM installed version of Huawei Assistant app now tells me that an update installed is the international version and cannot be used, please uninstall updates. When I do this, it just updates itself! This is going round and round even when telling it not to update, it does it in the background. See screenshots attached.
If someone could extract/export/link to a copy of the original and any updates for the Chinese version AN00 or equivalent has had, I will try to remove and install by adb.
I have emailed Huawei but as normal, no response received.

All sorted now. I had to uninstall the international updated app, then change app store to China version, wait for the update, then change it back to UK.
This allowed it update the China rather than the international app version.

Why I can't load the news?! Always show no data! I try to fix in many ways but no luck

Try setting region to UK it works .

How do I flash Global stock Rom onto a Chinese edition OnePlus 8T.

Hi all,
I'm thinking of purchasing a OnePlus 8T Chinese edition here in the UAE as it is much cheaper. However, I'm concerned with whether the software will be the same as the international units. Hence I want to update to the latest non-Chinese edition. I believe the Chinese editions come with HydrogenOS which I don't want. My question is will I be able to update my phone to the latest version of Oxygen OS if I buy the phone? If yes, could you please tell me how? I know I have to find the stock ROM for a different region and flash the device. But I've searched everywhere I could think of: the official OnePlus site doesn't provide a version as it has with other models yet, and I couldn't find any 3rd party link either. Any help would be appreciated.
Thanks in advance.

The 8T I bought was listed as Chinese but came with OOS (KB05AA) installed and I've had no issues updating it. It's model number is KB2000.

OnePlus 8T Chinese Variant - Return To Stock

Hi all,
I have searched on many threads on XDA and even other sources, but I can't find a solid answer, I don't like to create new threads, but in this case, I had to.
I am going to buy the Chinese variant of the OnePlus 8T, which is advertised to be shipped with Hydrogen OS. I have seen many guides and videos on how to switch to Oxygen OS and it seems very easy and straightforward.
My only concern is, that I will have to root the device (using this guide: https://forum.xda-developers.com/t/...in-eu-us-kb2000-kb2001-kb2003-kb2005.4178675/ ) and I am unsure how to return the device to stock.
From what I have read, the KB2000 Chinese variant does give a crashdump error if you use the normal MSM Download tool made for the global devices to flash the Chinese variant, because it shipped with Hydrogen OS, and not Oxygen OS.
Now I read on this thread that this is the working version of the MSM Tool for the Chinese KB2000 Hydrogen OS devices.
A few people confirmed that this is indeed working, but I am importing this phone to South Africa, and just want some extra peace of mind before I make the purchase.
My apologies if someone feels I created this post unnecessarily, but I am willing to write a guide for the Chinese version on how to return it to stock to help somebody else out there.
I will truly appreciate it if somebody can shed some light on this thread.
Thanks a lot everyone!

To return to stock you can use latest HydrogenOS MSM or OxygenOS MSM tools or even flash unpacked firmware files directly from fastbootd.

I think returning to stock HOS or OOS is not such a problem.
Look more precisely on other things like carrier support of chinese version (KB2000) in your country, especially if you're going to use 5G, because chinese version has different LTE/5G bands, so it may not reach max internet speed your carrier provides.
