IMPORTANT NOTE:
Custom ROMs available from the community requires latest OxygenOS 11 and up firmware.
So, if your device comes with ColorOS and want to flash custom ROMs. We recommend to Convert first your OnePlus 9R ColorOS to OxygenOS via MSM tool and update to the latest OTA before unlocking your device.
This Firmware updater is an essential file to update your firmware once the OxygenOS release the latest updates without reverting back or MSM to stock rom from your current custom ROM.
I know some of you are familiar with Xiaomi Firmware Updater, and it is similar and the same process.
Enjoy

That is the final baseband version of the OxygenOS 11 from 9R,
Please take note that not only modem.img is update as well the some images partition inside the zip file that are essential in firmware updating.

Please take note that our Android 12/12.1 Custom ROMs as of now are using Android 11 blobs, Device, Vendor and Kernel trees from OxygenOS 11.
As advise, we are highly recommended to use latest OxygenOS 11 firmware as of the moment since the kernel source for Android 12, blobs and trees are not yet available and we don't recommend to use OxygenOS 12 firmware to avoid issues.
