Unlike standard recovery methods (like sideloading an OTA update via ADB), the MSM tool communicates directly with the device’s (EDL mode – Emergency Download Mode). This mode is baked into the processor itself, meaning that even if your bootloader is corrupted, your recovery partition is wiped, or your screen is completely black, the tool can theoretically resurrect the device.

Many OEMs implement anti-rollback protection to prevent downgrading to vulnerable firmware versions. Version 2.0.71-rcsm includes patched security checks that allow technicians to flash slightly older firmware than what the device expects—useful for recovering from a bad update. msmdownloadtool-v2.0.71-rcsm
