Tool: Qualcomm Premium

Success rate is highest on Xiaomi (due to leaked engineering loaders) and older Samsung (S9/S10/Note 9 era). Newer Samsung (A53, S22) with Qualcomm Secure Boot v3 fails.

The tool uses one of three bypasses:

4/10 – No progress bars, frequent “Not Responding” during large operations, requires manual driver installation, cryptic error codes ( Sahara error 3 = wrong loader, Sahara error 6 = handshake timeout).

The tool can delete the locksettings.db , gatekeeper.password.key , and fingerprint.db files directly via the file system abstraction layer. This unlocks the phone entirely, preserving user data (unlike a factory reset).

Users can read, write, and erase firmware partitions in both EDL (Emergency Download) and Fastboot modes .
