Its primary job is to execute memory reads, memory writes, and cleanly inject an emergency programmer file (commonly known as prog_firehose_ddr.elf or prog_emmc_firehose.mbn ).
Technicians can use tools like Qualcomm Flash Image Loader (QFIL) or QPST Software Download to re-write fresh partition tables ( gpt_main0.bin ), bootloaders, and system images back onto the flash storage using the same Sahara protocol pathways. qpst sahara memory dump upd

The GPT (GUID Partition Table) or boot partitions are corrupted.
Note: Sahara requires this file to initialize the DDR memory controllers on the phone; without it, the memory dump tool cannot access the full physical address space. Step 4: Map the Output Directory and Run
