Free A12 and A13 Passcode Erasing Tool Bobik Eraser PwnDFU

Bobik Eraser is a free A12 and A13 passcode erasing utility for experienced iOS repair and research users. It erases the device and its existing passcode state, then returns the supported device to the Hello setup screen.

Important data warning: this is an erase operation, not a passcode recovery method. It does not reveal the passcode or recover user data. The procedure can permanently remove all information stored on the device. Use it only on a device you own or are explicitly authorized to service.

How to Use Bobik Eraser

This overview is intentionally concise. Read the included PDF because the precise PwnDFU connection sequence matters.

  1. Confirm that you own the device or have written authorization to service it. Back up any accessible data before continuing.
  2. Prepare the supported RP2350 board and place the device into PwnDFU by following the included USBLiter8 documentation.
  3. Extract the package that matches your computer and launch the Bobik Eraser utility.
  4. Confirm that the utility detects the device in PwnDFU, then follow the on-screen erase instructions.
  5. Keep every cable connected until the process finishes and the device returns to the Hello setup screen.
Before starting: close other phone-service programs that may take control of the same USB connection. Never disconnect the RP2350 board or Apple device while an erase operation is running.
