Download OnePlus 9RT OxygenOS 11 and ColorOS 12 Firmware

From this post, you could download the OxygenOS 11 (Android 11) and ColorOS 12 (Android 12) firmware for your OnePlus 9RT. The OEM started its journey as a flagship killer and at the same time was an active player in the custom development (well, the original OnePlus ran CyangenOS (which is now LineageOS) as its stock ROM!). However, the budget domain soon started flooding with a plethora of offerings from other OEMs.

But even then, the OnePlus underlying OS skin was still the differentiating factor and one of the major reasons why users were inclined to these devices. Running, OxygenOS in Indian/Global markets and HydrogenOS in Chinese regions, it maintained a perfect equilibrium between features and stability. And even though the OEM was a sinking ship in recent years, its OS skin managed to keep it afloat. But not anymore.

Thanks to their weird decision-making, it ditched its popular OxygenOS in favor of Oppo’s ColorOS. So beginning with Android 12, your OnePlus device will now be running the ColorOS, and you don’t have much say in that (unless you have an unlocked bootloader, which we will be discussing later on). As far as the OnePlus 9RT is concerned, it was launched in China with ColorOS 12 (Android 12) firmware.

On the other hand, in India, it beholds the OxygenOS 11 Android 11 and is slated to get the ColorOS 12 somewhere around the end of March. With that said, you could now download both the OxygenOS 11 (Android 11) and ColorOS 12 (Android 12) firmware for your OnePlus 9RT device from this guide. Apart from that, we have also provided the boot.img file for the corresponding firmware that you could patch via Magisk and hence use it to root your device.

Benefits of Manually Flashing OnePlus 9RT OxygenOS 11/ColorOS 12 Firmware

So when you would already be getting automatic OTA updates, why is there a need to manually flash the firmware? Well, here are a few important reasons why you would need to manually flash the stock firmware:

  • In some instances, an OTA might take time to arrive, so if you have got the ROM ZIP file from a trustworthy forum such as XDA, then you could directly sideload it onto your device.
  • Next up, if you wish to root your device, then you will have to download the stock firmware for your device, extract the boot.img from payload.bin, patch it via Magisk and then flash it via Fastboot.
  • Moreover, if your device is soft-bricked or boot-looped, then you could manually flash the firmware onto your device and bring it back to life.
  • If you wish to switch from ColorOS to OxygenOS, then you will have to download the OxygenOS firmware and flash it via Fastboot.
