Writing to system partitions carries a high risk. If the wrong file is flashed to the wrong partition (e.g., flashing a bootloader file to the modem partition), the device can be permanently "hard bricked" (rendered unrecoverable).
In fact, Samsung has been using Qualcomm's Snapdragon processors in many of its devices, including the Galaxy S10+. This partnership has enabled Samsung to leverage Qualcomm's expertise in firmware development and testing.
Security patches released by Samsung consistently patch the vulnerability windows utilized by tools like QSF. If a device has a security patch level that is too recent, the AT command injection or MTP exploit may fail silently or cause the device to hang. qsf tool qualcomm samsung frp

QSFR (Qualcomm Secure Firmware Recovery) is a tool developed by Qualcomm Technologies, Inc. It's used to flash or repair firmware on Qualcomm-based Android devices, including Samsung devices. This partnership has enabled Samsung to leverage Qualcomm's
A data-capable USB cable plugged into a physical USB 2.0 port on the motherboard minimizes data corruption during low-level flashing.
Before launching any software, your computer environment must be prepared to communicate with low-level Qualcomm architecture.
