Mastering the Phison MPALL v3.70.0e: The Ultimate Guide to Flashing Your USB Drive

In the world of data recovery and USB drive repair, few tools carry as much weight—or as much risk—as the Phison MPALL utility. Among the myriad versions floating around on forums and tech sites, one specific iteration stands out for its balance of stability and compatibility: Phison MPall V3.70.0e.

3. Creating a CD-ROM Partition (Dual Drive)

High-end IT technicians use this tool to "flash" a USB stick to appear as a CD-ROM drive containing an ISO (e.g., Windows Installer) plus a separate storage partition. Version 3.70.0e excels at "Mode-A" and "Mode-C" partitioning. Mastering the Phison MPALL v3

Close MPALL.
Physically unplug the USB drive.
Wait 10 seconds.
Plug it back in.
Open Windows Disk Management and initialize the drive (MBR/GPT) and create a new volume.

Always scan downloaded executables with VirusTotal—some AVs flag MPall as a “hacktool” (which is technically true, but not malware). Close MPALL

Warning: This tool is powerful. It will completely erase all data on the drive. It’s a repair tool, not a data recovery tool.

[OPTION]
USB_MODE=3
CDROM_ISO= (Leave blank for recovery)
FORMAT_TYPE=1   (1 = Low level format, 2 = Quick format)
FORMAT_BLOCK=1
[FIRMWARE]
ISP=0   (Set to 0 unless you are 100% sure the FW file is correct)

Data Loss is Absolute: There is no "undo" function. The tool overwrites the firmware, wipes the flash translation layer (FTL), and low-level formats the NAND cells. Backup everything first—or accept total loss.
Wrong Firmware Kills the Drive: Selecting an incorrect firmware file (e.g., using a PS2251-03 firmware on a PS2251-07 controller) will brick the drive. Recovery from that requires shorting specific pins on the NAND chip.
Antivirus False Positives: Many security suites flag MPall as a potential threat (usually "HackTool:Win32/Keygen"). This is because the tool uses low-level USB access methods and driver behavior similar to debuggers. However, only download from reputable sources (like USBDev.ru or FlashBoot.ru) and verify the SHA hash if possible. Malware-laced versions exist on third-party adware sites.
Only for Phison Controllers: Using it on a drive with an Alcor, Silicon Motion, or Innostor controller will not work and may crash the PC.

For those attempting a repair, it is often necessary to put the drive into "Test Mode" (shorting specific pins on the controller) to make it visible to the software if it is not detected normally.
