A Firehose file is a low-level programmer protocol used by Qualcomm chipsets. It acts as a bridge between the device’s primary bootloader and the computer software (such as QFIL or QPST).
When an Android device is powered on, it goes through a chain of verification (Bootloader -> Little Kernel -> Android Kernel). If this chain is broken—commonly known as a "hard brick"—the device cannot boot into the Operating System or even Recovery Mode.
This is where the Firehose protocol comes in. It allows the computer to communicate directly with the eMMC or UFS storage chip on the motherboard via the EDL (Emergency Download) mode. Essentially, it gives the software "superuser" access to the device's storage, allowing for the writing of partitions that are otherwise locked or inaccessible. oppo a57 firehose file
