The device is powered by the MSM8953 chipset from the family. By the end of 2019, its QFIL/EDL file was closely guarded by OEMs due to commercial restrictions.
In EDL mode, the device cannot accept standard firmware flashing commands because it lacks the necessary instructions to interact with the storage drive.
However, EDL mode by itself cannot execute high-level flash commands. It requires a programmer file to act as an intermediary between the computer servicing software and the device’s storage hardware. This is where the Firehose file comes into play.

The eMMC storage chip itself may have entered a permanent read-only hardware state due to component degradation or physical damage, meaning the programmer cannot modify the memory cells.
After the Firehose loader is active, the PC and device switch to the , which handles the actual flash memory operations. The Firehose loader now has direct access to the eMMC storage and can execute commands sent from the PC. When the PC tool (like QFIL) sends an XML command to read a partition, the Firehose loader carries it out on the hardware. The Firehose protocol is responsible for executing the specific instructions defined in the rawprogram0.xml file, which typically include formatting partitions, writing images, and erasing specific areas.
If you have ever attempted to flash, unbrick, or modify a smartphone powered by the Qualcomm Snapdragon 625 processor, you have likely encountered the term . This specific file is a critical component in the Android engineering and repair ecosystem. Without it, recovering a deeply corrupted or "hard-bricked" device would be nearly impossible for standard technicians. The device is powered by the MSM8953 chipset from the family
: Ensure your device is recognized as Qualcomm HS-USB QDLoader 9008 in Windows Device Manager.
If the phone is already hard-bricked, simply plugging it into a PC may trigger EDL mode automatically. Open Windows Device Manager and check under . You should see Qualcomm HS-USB QDLoader 9008 (COMxx) .
As the days turned into weeks, the team's frustration grew. The project was on the verge of being delayed, and the company's executives were breathing down their necks. However, EDL mode by itself cannot execute high-level
Select (this tells the tool where each image file belongs on the physical eMMC partitions).
