Flashing Instructions:

Pre-installation:

Flash rom + magisk = REBOOT

If you face black screen it's due to your tianma display so flash any other custom kernel because it have 65hz kernel by default which is supported on hauxing display only.

First time installation (clean flash):

Backup your data to PC, OTG flash drive

Boot to recovery (can do from bootloader or with buttons from power off state)

Now in recovery go to Install select zip + magisk and swipe to flash

Choose apply update and Apply from ADB

Now install crDroid zip via sideload

Code:

adb sideload crDroid.zip

Go back to main menu and reboot to recovery to install gapps (if you don't want gapps, reboot to system)

To install gapps, simply sideload gapps.zip the same way you installed crDroid.zip then reboot to system

For Magisk, I've also included patched boot.img in the recovery folder from download page.

I have an O2 XDA Orbit2 original OS WM6 professional. Very limited Blutooth Integration with my car[Landrover freelander 2]

I have upgraded to WM 6.1[ from O2] but still there has been no change in the Bluetooth functionality with my car's Bluetooth PTI. No audio output through speakers. Rest of the functions seem fine. Similar OS tested and listed by Landrover as fully compatible with other models of Land rover. Any help in resolving this issue please?confused:

Hello. Im from VietNam, I'm using coloros12 in this my device. i want to experience oxygenos11. When do we have ROM OXYGENOS11?
[OnePlus 9RT] bonez56:
I am from Australia and also using a Chinese model of the 9RT. I am eagerly awaiting to see if/when an Oxygen OS ROM will be made available also. Even if it's the official, I am fine with that.

ColorOS is driving me crazy with the battery saving settings being extremely aggressive, which kills all my apps shortly after launch meaning I do not receive push notifications from apps that are not configured to 'auto launch'.

Auto launch is also capped at 5 apps, plus some extra messaging apps like FB Messenger, Whatsapp, Telegram etc.
[OnePlus 9RT] Buzzymoon:
One plus is gone. The brand is over
[OnePlus 9RT] kydan2002:
@bonez56 please do let me know if you get a copy of the indian ROM. I've been attempting to get it through OnePlus.in support, but havent been successful yet. I also have a chinese variant of the 9RT.
[OnePlus 9RT] bonez56:
Are you having similar issues to me with apps being killed (or refusing to run in the background) and therefore you aren't receiving any push notifications? My device came shipped with Google Play already side loaded, but when I got it out of the box I factory wiped it and side loaded it myself, so hoping that I didn't do anything differently to what they did before shipping it.
[OnePlus 9RT] kydan2002:
I bought mine directly in China and I've not yet side loaded, with the hope that we'd get a global/Indian ROM build soon. I'd like to avoid root and TWRP if possible.
[OnePlus 9RT] bonez56:
I haven't rooted mine, nor installed TWRP. I've just enabled 'install applications from other sources' and side-loaded the Google stuff onto it, so I can access Play Store. Having only the Chinese app store is not an option for me.
[OnePlus 9RT] ThingVn:

OxygenOS 11 Indian ROM is available on the Oneplus OTA telegram group (not sure if its official group or not). Also I haven't tried cross flashing yet neither, but if its the same as OnePlus 9, it should be working as well.
[OnePlus 9RT] berd95:
could you share the Link please?

I found a Telegram Group, but couldn’t find the full Image. Thank you :)
[OnePlus 9RT] penguinus:
Full ROM is not available as of now. In telegram group there is incremental OTA update that doesn't contain full ROM. And even with full ROM it may be not possible to switch chinese version from ColorOS to Oxy.
[OnePlus 9RT] berd95:
At least with the OP9 it was possible to switch I think.

Why the Hell isn’t the full ROM available at oneplus.in

And what’s also bothering me, could I flash the original OP9 Global ROM because the Hardware is almost identical to the 9RT?
[OnePlus 9RT] penguinus:
Well, 9R doesn't have so much options to migrate as global verions. I think we should look on 9R that is also only for China and India.

I think it will be available later, when there will be updates. As of now we only one week after release in India and there is no major updates.

No. It is different devices, it may be similar by some specs, but there are differences in things like camera, modem and so on. Basically you should use roms for 9 to flash 9 and roms for 9RT to flash 9RT.
[OnePlus 9RT] abhishekcma:
I am using Indian ROM 11 OS and it works really good.
[OnePlus 9RT] berd95:
can you dump it?

Yeah just used couple of hour's and if I get a better one sure I am. Untill and unless some good developer start making new ROM and I switch to twrp and using flawless ROM.

Olá, você usou a rom indiana no chinês Oneplus 9RT? Poderia enviar o link de onde baixou?

Sí, estoy usando la ROM india de oneplus 9RT. Oneplus solo proporciona actualizaciones incrementales, no toda la ROM.
[OnePlus 9RT] EduFaol:
I still haven't found the complete rom to download, just an update, so I asked for the link
[OnePlus 9RT] abhishekcma:

[OnePlus 9RT] EduFaol:
É o jeito esperar
[OnePlus 9RT] berd95:
and not even the oneplus india support has a Link for the ROM by the way, I contected them
[OnePlus 9RT] archz2:
I don't understand why Oneplus releases different variations for their ROMs in different countries. Is it because of government regulations? I had a hard time rooting my device just because the official ROM wasn't available and I used the img file from someone else on this forum.
[OnePlus 9RT] penguinus:
It is a first half of answer. OnePlus had different roms for China and for all other world previously too (HydrogenOS and OxygenOS respectively). Chinese ROM doesn't contain Google apps, because Google is blocked in China. Instead of Google services it contains chinese replacements. In other aspects Hydrogen and Oxygen were similar.

Second half of the answer is current transformation of OnePlus. It basically merges Oppo brand, plans were anounced to merge Oppo's ColorOS with Oxygen and introduce new OS for both brands. But at current stage only chinese version (HydrogenOS) switched to ColorOS completely. These two OS-es are very different and not so compatible as previously. For 9RT chinese version (with ColorOS) released 3 month ago, but Indian version with OxygenOS is just released. It is lack of available ROMs as of now. I bought chinese version of phone on Aliexpress and waiting for possibility to switch from ColorOS to OxygenOS.

Looks like the Chinese users have found this OOS upgrade package

https://www.oneplusbbs.com/thread-6223252-1.html
[OnePlus 9RT] g96818:
Maybe this version also has the same bug that prevents bootloader unlocking or maybe it has the efuse script that permanently disables unlocking the bootloader. You should try again after the next update.
[OnePlus 9RT] EduFaol:
Thank you in advance for your help and that of the other members, I'll keep him and wait for a position from Oneplus, or launch a global Color OS or better launch an Oxygen OS for him without needing to unlock bootloader. install the ROM by the update. Apart from these situations, the smartphone is good and beautiful in my point of view.
[OnePlus 9RT] kydan2002:
I ran this on my chinese version of the op9RT and it appears to be working as expected. However, looking through the logs after running I saw the following:

```

Sending 'modem_a' (225280 KB) OKAY [ 6.132s]

Writing 'modem_a' FAILED (remote: 'Operation not permitted')

fastboot: error: Command failed

```

My device does successfully connect to LTE and can make both calls and get data so the modem appears to be working properly, but should I be concerned about this?
[OnePlus 9RT] EduFaol:
managed to unlock bootloader and install Indian ROM? man every day i try but in the command fastboot flashing unlock the error. I'm thinking it was an update I did from Color OS before trying to unlock
[OnePlus 9RT] ThingVn:
Can you take a video of your screen so I can see it step by step?
[OnePlus 9RT] Valdem:
Hello everyone.

I am owning OnePlus 9RT China version with ColorOS and looking for a way how to switch to OxygenOS. The installer which is published in this thread works, however you can't lock bootloader with this version of firmware. I'm doing some investigation at this issue and need support from the people who own Indian version of device with ROOT.

Currently, I can switch between lockable ColorOS version and unlockable OxygenOS versions in both ways.

My goal to find a way for converting the device to OxygenOS with ability to lock bootloader.

If someone is willing to help me with my research - please PM me.
[OnePlus 9RT] EduFaol:
I am not able to unlock the bootloader, that way would be of great help. I really want to get out of this Color OS and use OXYGEN OS on my Oneplus RT with all languages

[OnePlus 9RT] Valdem:
I reach some point where I need a boot.img from OxygenOS version A3. All images what I have found is from version A2. Could someone check theirs boot.img files?

I'm looked for a file with size - 201326592 and SHA256: b016c7e8b65d508effcb9fb7c4175bf87e15a969f25b427f014bad321fdddd12.
[OnePlus 9RT] Valdem:
I finalize my research and have fastboot version of OxygenOS firmware which can be flashed to chinese devices (MT2110). Bootloader CAN be locked with this firmware.

This method based on research which was done in previous version of OxygenOS fastboot ROM. Difference only in consistent versions of images inside (all now version A03).

This ROM is working on my personal device and tested by @penguinus on his device without issue. However I saw some reports about devices with customized ColorOS ROM. At least that person was not successful with previous version of OxygenOS fastboot ROM.

If someone is willing to test this ROM on hir device - please PM me and I will share link to firmware. After collecting some feedback I'm going to release this ROM for public.
[OnePlus 9RT] EduFaol:
Post the link that I managed to unlock the bootloader today and I'll test it.
[OnePlus 9RT] soulvayne:
Were you able to put TWRP on your phone and then flash the rom? Or did you do it through ADB/fastboot commands? Because I'm looking to put TWRP on my (chinese) OnePlus 9RT. But I want to be able to go back with a backup in case something is not to my liking. Can you help me with that ?

Also I want to know when you flashed the the Indian Oxygen OS, are you able to make use of Android Auto again? Because that is my main goal.

Sorry just seeing this. I was able to unlock the bootloader as described in the root HOWTO thread in this forum and flash OxygenOS with the file and instructions provided above. I was on macOS, so I had to copy in mac compatible adb and fastboot binaries, as well as run the .bat script by hand, but it was very straightforward.
[OnePlus 9RT] aenerv7:
Is there any way to switch from OxygenOS back to ColorOS? I can't find any fastboot type ROM for 9RT. I tried some payload dumper to dump ColorOS Full OTA payload but not work.
[OnePlus 9RT] Valdem:
Yes the same type of firmware exists to move back to ColorOS but it is tested only on devices which was originally on ColorOS.
[OnePlus 9RT] aenerv7:
My device is Chinese version so it is originally based on ColorOS. But I can't find any ColorOS fastboot ROM to flash back. I try to dump the ROM from latest ColorOS full OTA by payload dumper tool but has no luck. Could you please share me the ColorOS fastboot ROM?
[OnePlus 9RT] penguinus:
ColorOS A10 fastboot ROM

Don't forget to do wipe in recovery if you moved from Oxygen.

Tested on chinese version of device, but should be ok for indian too.

Bootloader can be locked after flasing this ROM.
[OnePlus 9RT] aenerv7:
Thank you very much! I will try to flash the rom now.
[OnePlus 9RT] EduFaol:
I'm passing by to thank the person responsible for posting the Oxygen OS ROM and the method on how to install in addition to unlocking the bootloader. just wanted to add a few more details that might help those who don't have a lot of experience with Oneplus like me, download the Qualcomm driver and disable the windows driver signing. I just got the flash-all.bat file to load to the end this way, Now wait for the latest ROM to be posted to make updates.
[OnePlus 9RT] Valdem:
If you didn't flash magisk - you can use system updater (Settings->Software update) to get version A.04
[OnePlus 9RT] g96818:
Update doesn't work, even after removing magisk
[OnePlus 9RT] Valdem:
I told "if you didn't flash magisk". Magisk change several partition on the system. You can't restore them by just uninstalling magisk.

All the partition patched by magisk should be restored before incremental OTA can be installed. The simpler way will be to flash full fastboot firmware based on latest OTA without cleaning user data.
[OnePlus 9RT] g96818:
Watch your tone. Magisk doesn't change partition size.
[OnePlus 9RT] Valdem:
I'm watching my tone. If you are not sure what magisk doing during its installation - please check their documentation. Magisk patching several partitions (I didn't tell about size, content also is important), at least 'boot' and 'vbmeta'. During uninstalling, magisk can restore only 'boot' but not 'vbmeta'. However the way how incremental OTA is work requires not touched state ALL the partition which present in this OTA (both mentioned above usually there). That condition can't be satisfied by just uninstalling Magisk.
[OnePlus 9RT] g96818:
You obviously don't know what you're talking about. I've been flashing OOS OTA updates longer than anyone else. I'm the one that gave people the instructions on how to flash OOS OTA updates if the full zip isn't available.

The problem isn't magisk. The problem is this fastboot conversion isn't legit. I had my doubts that you can update this OOS conversion normally and I am right.
[OnePlus 9RT] Valdem:
I have MT2110 device which initialy had installed ColorOS. I have done installation of Oxygen OOS A.03 on my device with custom firmware and was able to lock bootloader on my device and upgraded it to A.04 with OTA update received over the air.

That prove that if you doesn't modify device with Magisk - you can apply OTA over the air.

What I'm doing wrong? Device is still locked.

I understand that way how this convertation is done is not official. But there is no official way from the vendor and people ready to use this custom firmware to switch to OxygenOS. Also I collected some feedback from users who did the same convertation during last week. No one reports about incorrect behavior of this version of firmware.

If you want I can try to find which exactly partition is modified by magisk on this device, that it prevents to install OTA update.
[OnePlus 9RT] Valdem:
Sorry, I need to take my words back. Latest stable version of Magisk 24.1 is able to revert all the changes what it is done on the device.

I did the next test:

1. Flash OxygenOS A03 to device.

2. Root device with Magisk 24.1

3. Try to install OTA on rooted deviece (obviously without success)

4. Uninstall Magisk by MagiskManager

5. Try to install OTA one more time. Now update successfully installed to device.

Now I have a question. Which version of firmware and which version of Magisk do you use in case when you got failed with OTA after Magisk uninstallation?

If you use firmware which was released 03 Feb. It is obviously can't be updated by OTA, because device bootloader with that version can't be locked. There is other version of firmware exists. Device bootloader can be locked with that version. I did my test with this (newer) version.
[OnePlus 9RT] kwanhongboy:
I am also waiting a OOS that can lock bootloader with OTA working:cry: seems oneplus not going to put the offical rom on their page.
