2. Requirements

  • MRT hardware card (USB/PCIe) + software license
  • Target HDD connected via MRT’s dedicated port (not SATA directly to PC)
  • Firmware resources (ROM dump, modules from a donor drive or database)
  • PC with Windows 7/10 (MRT often runs on older stable OS)
  • Backup of original drive data (flashing can wipe access)

3. Key Features & Performance

Step 4 — Backup Original ROM

Always backup before writing

  • Click Read ROM → save file as original_rom.bin.
  • If read fails, drive may need boot code injection first.

Supported Drive Families

The MRT HW Flash Tool 77 is not vendor-locked. It supports: Mastering the MRT HW Flash Tool 77: A

  1. Western Digital (all families: Marvell, TD, Royl, even new ARM-based PCBs)
  2. Seagate (F3 architecture – including locked ROMs on 7200.11, 12, 14)
  3. Samsung (HD series and Spinpoint M8 – handles head map in ROM)
  4. Hitachi/IBM (Deskstar, Travelstar – including NVRAM corruption)
  5. Toshiba (MQ and DT series – difficult to access via terminal)
  6. Fujitsu (MH and MHY series)

Additionally, it works with SSD controllers (Phison, SandForce, SM) that expose firmware via a serial flash interface, though SSD recovery is more complex and may require additional adapters.

4. Preparing the Device (EDL / 9008 Mode)

To perform a hardware flash, the phone must be in EDL (Emergency Download) Mode.

  • Method A (Button Combo): Power off the phone. Hold both Volume Up and Volume Down buttons and connect the USB cable to the PC. If the device vibrates and the screen stays black, check Device Manager for "Qualcomm HS-USB QDLoader 9008".
  • Method B (Test Point / ISP): If the phone is hard bricked and won't enter EDL via buttons, you must open the phone back cover, disconnect the battery, and short the "Test Point" (two copper pads on the motherboard) to ground while connecting the USB cable.
