Uncheck the box that reads "Auto reset after collecting memory dump" to stop continuous reboot patterns.
QPST Sahara memory dump and update capabilities represent some of the most powerful tools available for Qualcomm device diagnostics and recovery. From capturing crash dumps for kernel debugging to reviving bricked devices through firmware flashing, mastering these operations opens doors to deep-level device management that is simply not possible through standard user interfaces. If you are debugging a live device, you
Step 6 — Post-operation checks
: Unlike standard flashing modes, this mode handles "Debug Mode," which enables the transfer of the device's state at the exact moment of a crash. : Bad USB cables or ports are a
A device in "DUMP mode" may only show the DIAG port (9006) or remain in a black-screen state where the charging indicator does not light up.
