USBLITER8 – A12/A13 RP2350 Pwn DFU & Firmware Setup Guide

A complete guide to selecting supported RP2350 boards, flashing firmware, and using USBLITER8 Pwn DFU for Apple A12 and A13 devices.

1. Hardware Requirements

USBLITER8 currently supports the following RP2350 development boards.

2. Firmware

Download the firmware package from:

https://mega.nz/folder/mRUzDCxK#n9Gq-Jfgvqp7tERKmXeiMQ

• Each supported board requires its own firmware.
• Always flash the firmware that matches your board model.

Supported firmware includes:

• Waveshare RP2350 USB‑A
• Waveshare RP2350 Zero
• Pimoroni Tiny2350
• Raspberry Pi Pico 2

⚠️ Flashing the wrong firmware may prevent the board from working correctly.

3. Flashing the Firmware (.UF2)

The flashing procedure is identical for all RP2350 boards.

1. Step 1: Disconnect the RP2350 board from your computer.
2. Step 2: Press and hold the BOOT (BOOTSEL) button.
3. Step 3: While holding the BOOT button, connect the board to your computer.
4. Step 4: Release the BOOT button. A removable USB drive will appear. Typical drive names include RPI-RP2 or RP2350.
5. Step 5: Drag and drop the correct .UF2 firmware file onto the drive.
   Example filenames:
   • usbliter8.waveshare_rp2350_usb_a.uf2
   • usbliter8.waveshare_rp2350_zero.uf2
   • usbliter8.pimoroni_tiny2350.uf2
   • usbliter8.pico2.uf2
6. Step 6: Wait 2–5 seconds. The board will automatically reboot. Firmware installation is now complete.

4. Hardware Connection

Option A — Waveshare RP2350 USB‑A

This is the easiest installation method.

Computer → RP2350 USB‑A → Lightning Cable → iPhone (DFU Mode)

• No cable modification is required.
• No soldering is required.

Option B — Raspberry Pi Pico 2 with cut Lightning cable

For Pico 2, solder four USB lines. USB cable wire colors can vary, so do not trust color only. Confirm each wire with a multimeter or a known cable pinout before soldering.

Pico 2 Pin	USB Signal
VBUS	USB 5V
GND	Ground
GP12	D+
GP13	D−

USB Data Cables – Before connecting your device, verify:

• D+ and D− are not swapped.
• There is no short circuit between VBUS and GND.

5. Using USBLITER8

For the highest success rate, follow this sequence:

1. Connect the iPhone to your computer.
2. Put the device into DFU Mode.
3. Power on the RP2350 board.
4. Wait until the status LED becomes orange.
5. Connect the iPhone to the RP2350 board.
6. The LED will blink blue – the exploit is running.
7. When the LED returns to green, the process has completed successfully.

6. LED Status

LED Status	Description
Orange	Board is ready or the operation
Green	USBLITER8 has completed successfully
Red	Exploit failed, reconnect Board and try again

7. Troubleshooting

If the board does not work as expected:

• Verify that the correct firmware is installed.
• Check your USB cable.
• Confirm the device is in DFU Mode.
• Inspect all wiring connections.
• Ensure D+ and D− are not reversed.
• Make sure there is no short between VBUS and GND.
• Reflash the firmware if necessary.
