Originality/HydrogenOS

If you have a Chinese Cyberpunk Edition phone with OxygenOS, you'll notice that the Cyberpunk theme/assets are missing, and OTA updates lead to a boot loop. This guide will tell you how to restore the phone to its original software (HydrogenOS), unlock the bootloader, root it, and get Google Apps working. If you are American, this is the golden ticket. OTA updates will work and you will get the original theme/assets back.

I have made this guide because I purchased a Cyberpunk phone and the vendor installed OxygenOS. The Chinese Cyberpunk Edition phones are meant to use HydrogenOS. OxygenOS is not currently designed for the Chinese Cyberpunk Edition phones, despite many vendors installing it. I've spoken to Oneplus and it doesn't appear there are immediate plans to support the phone using OxygenOS.

This information is only for Chinese Cyberpunk Edition phones.
Rooting the phone is optional if you just want Google Apps.

Proceed at your own risk.



Setting Up

You're going to need to download and install these things for the remainder of the guide.

If you've already been toying with the phone, you might already have these. If so, skip ahead.


Restoring HydrogenOS (Credit: Some_Random_Username)

You are going to want to download the MSM Download Tool, designed for Chinese KB2000 phones. This tool will wipe your phone and restore the original HydrogenOS software, as well as your Cyberpunk theme/assets.

You will need to download the tool here:

https://androidfilehost.com/?fid=10763459528675590014 or https://drive.google.com/file/d/1-MwwMBiszDvAoCoqH1P5aZRaLvDFL_66/view
The difference is only in HOS version.
If your phone is made after march 2021, i suggest using latest one HOS MSM (google link).

After downloading:
  • Extract the archive to a folder.
  • Remove any Chinese characters from folder names (if applicable).
  • Open "MsmDownloadTool V4.0".
  • Under "User Type", select "Others".
  • Click "Next".
  • Notice that "Target" is selected on the dropdown in the top-right of the window.
  • Change the option from "Target" to "H2" instead.
Now make sure your phone is ready:
  • Turn your phone off and wait a few seconds.
  • Press the "Start" button on the tool.
  • Hold both volume buttons down, while plugging your phone in through USB (to enter Qualcomm EDL mode).
  • The download tool will begin to work it's magic (should take 200-300 seconds).
  • Once it says "Download Complete", your phone should reboot into HydrogenOS.
  • Close the tool completely.

Perform the phone's setup, then decide whether you want to root the phone, or just install Google Apps. Your phone will be wiped if you unlock the bootloader.

If your device wasn't detected when running the tool, make sure you have the Qualcomm USB driver installed. To do this, open device manager. Under "QHUSB_BULK", select "Update Driver Software", and use the .cab file you found earlier.


Unlock the Bootloader (Optional)

Before you may root the phone, you will need to do the following.

Enable Developer Mode:
  • Open your Settings application and go to "About Phone".
  • Tap the section that says "Build Number" five times consecutively.
  • You will now have developer mode.
Enable OEM Unlocking/USB debugging:
  • Open your Settings application and click the search button.
  • Search for and enable the option: "OEM unlocking".
  • Search for and enable the option: "USB debugging".
  • You will be asked if you want to trust the device when it's plugged in. Click "Allow".
You will want to do the following, using the ADB/Fastboot you downloaded:
  • Make sure your phone is plugged in.
  • Run the following:
    • adb reboot bootloader
  • Your phone will reboot into the bootloader.
  • Run the following:
    • fastboot oem unlock
  • Use the volume/power buttons on your phone, to confirm.

Your phone will reboot and wipe itself, as well the Chinese applications. Perform the phone's normal setup again.

The bloatware and Chinese apps will return when you perform an OTA update at the end of the guide. They can also be removed/disabled.


Rooting (Optional)(Credit: DroidFreak32)

To root the phone we will be installing Magisk, using a patched boot.img from your current version of HydrogenOS. In this case, we are using version 11.0.1.2 (the version of the MSM Download Tool). I will be providing the boot.img from my phone, which I have used personally.

You will want to download the following:

Preparation:
  • Re-enable developer mode, as well as USB debugging. Just like you did in the previous section.
  • Transfer the app-debug.apk to your phone, and install it through the phone's file manager.
  • Copy "magisk_patched_11.0.1.2.img" to your computer's ADB directory.

Rooting:
  • Run the following:
    • adb reboot bootloader
  • Your phone will reboot into the bootloader.
  • Run the following:
    • fastboot boot magisk_patched_11.0.1.2.img
  • Your phone will reboot, using the patched boot.img.
  • Enter the Magisk Manager app you installed earlier.
  • Tap Magisk (Install) -> Perform Direct Install
  • You will have root on reboot!
If Magisk says it needs to reboot to apply changes, you will need to follow the last set of steps again.

If for some reason the boot.img I provided doesn't work, you will need to follow DroidFreak32's guide. His guide is very detailed and will instruct you on how to create your own patched boot.img and root the phone.


Installing Google Apps (Credit: Steve0007 and @xxxrichievxxx)

To install, you will want to obtain a copy of the Google Play Store from a 3rd Party. @xxxrichievxxx suggested this solution, which worked for me regardless of unlock/root status.

You'll want to download, copy, and run the newest version from your device:


We had also tried using WeebGapps, which has problems after updating:
https://t.me/s/WeebGAppsChannel?q=#Android_11+#magisk_mode (Requires Telegram)


Updating

Unlike on OxygenOS, you will actually be able to download and perform OTA updates, through the Settings app. If you do not follow the steps below when updating, you will lose root.

Disable your Magisk modules (if applicable) when updating, and re-enable after you have successfully updated!
I also recommend disabling "automatic system updates" via Settings, as they can break your root.

Follow these steps:

- Go to System-Update
- Tap OK when the message that you are rooted appears
- Tap "Download and install"
- Wait until you are prompted to reboot - DO NOT REBOOT NOW!
- Open Magisk Manager, select install -> Install to inactive slot and start installation
- When Magisk has finished installing, reboot and you stay rooted with latest OTA.

If you are missing the Play Store after updating, install it from here. If you happen to mess up or lose Google Apps, try uninstalling/reinstalling the module.

If you do happen to lose root, you will want to follow DroidFreak32's guide, as I've only provided the patched boot.img for 11.0.1.2.


Bloatware

You're probably annoyed by all the preinstalled garbage. I've made a short script that disables the Chinese market and removes all 3rd party Chinese (By_3rd and heytap) applications.

Removing Market and Almost All 3rd Party Apps:

You will likely need to run this script each update, as applications are added back on update. I've decided to leave the other applications on my device for now. If you want to remove even more, Steve0007 recommended this resource.

Updated the bloatware section. The script will now remove 40 bloatware apps. These apps may conflict with Google Play, so I do suggest removing them.

AWESOME!!!! Thank you very much!! Is google play installed as well? Last time I read something about all the google apps installed except Google play lol

Google Play has installed fine in my tests. However, updating might cause it to get removed. I'd keep a copy of the APK in your phone's storage, just so you have it if you need it.

You can find it here:

Hi, it's very strange, because on all oneplus, you can put hydrogen or oxygen without any problem.
Some people buy cyberpunk édition on Giztop or cect without any problem...very strange, no ?
Another question, IS it possible to add other language on hydrogen if de want to use it ?

Thanks

Went though this process to update, very well detailed. I went from Oxygen OS to Hydrogen then followed the rest of the steps to install Google Play.

I made the mistake of updating via OTA after restoring Hydrogen OS and had to repeat a couple step to get to the root step then followed the rest to install Google Play.

Youll need to download the 7z software to extract MSM software and one of the files needs a Telegram account. Its a messaging app that requires a phone number to create.

Also make sure you have the drivers sorted out, I had to do a bit of trouble shooting on the qualcomm drivers.

The cyberpunk theme is pretty cool.

I am having some spotty issues with google though, after updating OTA everything was fine but occasionally I will lose the play store. I have tried to directly install the apk and reinstall the module in magisk. But there is something kicking it off. The apps that I downloaded are still there, just the play store that drops. Edit: I am on module 4.0.4. Might try 4.0.5

Testing out the apps, I cannot get the maps app to work, keeps crashing. And for some reason I cannot log in to Chrome. It wont detect the account that is already logged into the phone (gmail, youtube etc) when I sign in manually it says 'This account already on device' I have signed in and out numerous times.

This is a pretty good solution to keep the cyberpunk theme, which you want if you have this phone. I get 5g speeds on US T-Mobile and have no issues with texts and calls. If the play store was more stable this will be a solid solution.

I've been reading and mentally preparing all the steps by downloading the required files and walking through them, but I've no development experience and I'm worried that if I mess up a step, I would have no idea how to unstuck myself...

For example:
If your device wasn't detected when running the tool, make sure you have the Qualcomm USB driver installed. To do this, open device manager. Under "QHUSB_BULK", select "Update Driver Software", and use the .cab file you found earlier.

I tried to look up my device manager on my PC and I do not see "QHUSB_BULK" so little things like that worry me :oops:

Is it possible to convert European 8T to full cyberpunk version?

Do not use this guide for that. It will not work. There's other threads on how to install the Cyberpunk goodies for a normal 8T.

I've been reading and mentally preparing all the steps by downloading the required files and walking through them, but I've no development experience and I'm worried that if I mess up a step, I would have no idea how to unstuck myself...

For example:

For the most part, any accidents are easily reversible, as there's a great guide on unbricking here:

It is as you say. Across multiple installs I've had minor issues with the Google Play store disappearing, but you can always reinstall the APK. I did not notice this until after I had made the guide.

@Steve0007 and I are looking for a more stable solution as we speak, so hopefully we'll have that soon!

Installing Google Apps (Credit: Steve0007)

To install Google Apps, we will be using WeebGapps (Magisk Module). There is no custom recovery available, so this is the best way to sideload Google Apps currently.

You will want to download the zip from this link:
https://t.me/s/WeebGAppsChannel?q=#Android_11+#magisk_mode (Requires Telegram)

After downloading the zip:
  • Transfer the zip you have downloaded to your phone's storage.
  • Open Magisk Manager
  • Select the Modules icon (looks like a puzzle piece)
  • Select "Install from storage"
  • Install the module's zip file
  • Your phone will reboot, with Google Apps
If you receive version errors when installing the module, download an older version. Version 4.0.4 worked perfect for me.


Updating

Unlike on OxygenOS, you will actually be able to download and perform OTA updates, through the Settings app. If you do not follow the steps below when updating, you will lose root.

Disable your Magisk module when updating, and re-enable after you have successfully updated!
I also recommend disabling "automatic system updates" via Settings, as they can break your root.

Follow these steps:



If you are missing the Play Store after updating, install it from here. If you happen to mess up or lose Google Apps, try uninstalling/reinstalling the module.

If you do happen to lose root, you will want to follow DroidFreak32's guide, as I've only provided the patched boot.img for 11.0.1.2.

Hello.

Thinking to experience the Hydrogen and using all related Google Apps at the same time but the file downloaded was in 7z format. Thought it is in zip format. How am I going to extract then?

Got it.

To be frank, how is it going? I mean with hydrogen os and having google apps workable at the same time?

After eliminating the bloatware, it's actually very nice. Asides from minor issues with the Play store vanishing, it should serve everyone's needs perfectly.

That said, I do encourage people abstain from installing the Google Apps if they are uncomfortable reinstalling the APK when or if it vanishes. We're finding a fix for this.

You mean, Google Play Store and/or Google Play Services, to be specific? It keeps vanishing even after all means taken into consideration?

Right now, I have already got the msm tool for hydrogen. Thinking about to go through it or not... hmmm...

    What is a procedure to switch from Hydrogen OS to Oxygen OS (due to that I need more languages, not only English and Chinese) ?

    Thank You in advance.
    1. First you will want to back up your apps etc. with the OnePlus Clone Phone app (formerly OnePlus Switch).
    2. Transfer the backup to you PC.
    3. Follow the guide in the link below to install OOS which will completely wipe your phone and install OOS:

    4. Setup OOS and install Clone Phone app to restore the backup stored on your PC. All Google apps will be installed including Play Store.


    5. You may or may not have the Cyberpunk theme once OOS is installed. Check settings/Customisation.

    From memory I did still have the CP boot animation, sounds etc. but not the live wallpaper. I used the following app to get the live wallpaper to work:


    Note: Following the most recent OOS OTA update, my device did in fact restore with all of the original Cyberpunk goodies working well including sounds, boot animation, charging animation and the live wallpaper... (You may have a different experience).

    If you decide to proceed with OTA updates in the future I would recommend that you use Clone Phone to do a backup first so you don't lose any data.

    Depending on the country you are in and your service provider, 5G/VOLte/VOWifi may not work without some further tweaking. This is usually relating to your mobile plan/ service provider and not the device itself. There are guides to activate these network features on XDA so just do some searching around.

    Good luck.

    I had received a PM, notifying me that the MSM Download Tool's link in the original post is no longer working...

    They have been linked and uploaded here, if you need them:

    I just tested and it seems to work without root or bootloader unlocked. I'd still recommend getting a copy of the full OTA update packages, in case you want to get root back later (for patched magisk).

    Netflix does show up without root, and you can still run the script to remove bloatware (USB debugging).
    Awesome, I am going to try this out.
