Wit 122-ufs V7.03 Driver

Typical BSP (Board Support Package) integration:

// Device tree fragment (ARM64 example)
&pcie0 
    wit122_ufs: ufs@0,0 
        compatible = "wit,122-ufs-v7.03";
        reg = <0x0 0x0 0x0 0x10000>;
        interrupts = <0 123 4>;
        queue-depth = <512>;
        use-msi;
        vendor-flags = "secure-erase", "fast-resume";
    ;
;

Driver registers as a PCIe driver:

static struct pci_device_id wit_ufs_ids[] = 
     PCI_DEVICE(0x1B4B, 0x1220), .driver_data = WIT_UFS_V703 ,
     /* sentinel */ 
;
MODULE_DEVICE_TABLE(pci, wit_ufs_ids);

First, let's break down the terminology:

In essence, the wit 122-ufs v7.03 driver is a software bridge that allows your Windows PC to communicate with a WIT repair box (or a compatible UFS programmer) via the USB interface. Without this driver, the PC will see the connected hardware as an "Unknown USB Device."

If you need to roll back to an older version (e.g., v6.0 for legacy hardware): wit 122-ufs v7.03 driver

Step 1: Disable Driver Signature Enforcement (Windows 10/11 only)

Step 2: Run the Installer

Step 3: Connect the Hardware

Step 4: Verify Installation

Manual Driver Update (if auto-install fails):

Even with v7.03, you may encounter issues. Here is a quick reference:

| Error Message | Probable Cause | Solution | | :--- | :--- | :--- | | "This device cannot start. (Code 10)" | USB port power delivery issue. | Use a powered USB hub or change to a rear motherboard USB port. | | "The driver is not intended for this platform" | 32-bit vs 64-bit mismatch. | Ensure you downloaded the x64 version of v7.03. | | "Driver is unsigned" | Windows Secure Boot is active. | Permanently disable Secure Boot in BIOS, or re-enable test signing mode (bcdedit /set testsigning on). | | "WIT Suite cannot detect box" | COM port number too high (>16). | In Device Manager, change COM port to COM3-COM8 via Port Settings → Advanced. | | USB device resets during UFS read | Outdated USB host controller driver. | Update chipset and USB 3.0 eXtensible Host Controller drivers from your motherboard vendor. |

Once the wit 122-ufs v7.03 driver is correctly installed, you unlock the following capabilities via the WIT Suite software: Typical BSP (Board Support Package) integration: // Device

| Feature | Description | | :--- | :--- | | Samsung EFS Backup | Read/Write NV data, IMEI repair (on supported models). | | FRP Bypass | Factory Reset Protection removal for Samsung OneUI 3.x/4.x. | | UFS Firmware Updates | Directly flash partition files (boot, modem, system) over USB. | | Dead Boot Recovery | Reboot Qualcomm and Exynos devices from preloader mode. | | Partition Manager | Read/write LUNs (Logical Unit Numbers) on UFS chips. |

Note: The driver alone does nothing—it must work in tandem with a compatible application (e.g., WIT Pro Suite v2.5+ or Octoplus Box).

A: Partially. The UFI Box uses a different USB VID (0x0483). You would need to modify the .inf file to add the UFI’s PID, but stability is not guaranteed. Stick to WIT hardware.
