Create a folder called Loaders inside the QSF Tool directory. Each Qualcomm chip needs a specific prog_emmc_firehose_XXX.elf or .bin . Do not download random loaders – extract them from your stock firmware package.
Unauthorized use of QSF may void warranties. Ensure you have legal permission to modify the target device.
Write down your target device’s processor model (check in Settings > About Phone or by removing the back cover).
If you tell me whether this is for a personal blog, a forum post, or a commercial repair site, I can tailor it further.
