STEP 1: Install Android SDK

As far as the OxygenOS 11 firmware goes, we already have its Fastboot ROM. So just extract it and you will get the boot.img file. Then if we talk about the ColorOS 12, we have extracted the boot.img from the payload.bin, so you may directly download the one that corresponds to your device from below: However, if you wish to manually extract the payload.bin file, then you check out our guide on How to Extract payload.bin and get stock boot image file.
