| Scenario | Why HiTool is used | |----------|--------------------| | | Phone doesn’t power on, no fastboot/recovery → HiTool can revive via serial boot | | Bootloader locked but need full flash | Bypasses normal restrictions; writes raw partition images | | IMEI repair / baseband fix | Direct NV partition access (requires proper XML/TLV files) | | Replacing damaged eMMC | After hardware replacement, writes bootloaders (xloader, fastboot) | | Custom ROM / GSI testing | Flashes experimental system images without bootloader unlock | | Factory or engineering repair | Used by service centers for flashing secure firmware |
Ensure the device is charged to at least 60% to prevent sudden shutdowns mid-flash.
