Authorize your Passcode-locked, "iPhone Unavailable", or "Security Lockout" Apple A12 and A13 devices on GrandUnlock using the official iRemove server integration. Utilizing the hardware-based USBLiter8 BootROM exploit via an external RP2350 microcontroller, this service allows technicians to backup original factory activation records, wipe lock codes, and restore full cellular network connectivity—enabling working SIM calls, SMS, LTE/5G data, iCloud login, and Apple services.

- Full Cellular Network Support: Retains original factory baseband and cellular ticket data (Calls, SMS, Mobile Data, FaceTime, and iMessage work normally).
- Supported Chipsets & Models:
  * Apple A12 Bionic: iPhone XR, iPhone XS, iPhone XS Max
  * Apple A13 Bionic: iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone SE (2nd Gen, 2020)
- Hardware Exploit Requirement: Requires an external RP2350 development board (such as Waveshare RP2350 USB-A or Raspberry Pi Pico 2) flashed with compatible interface firmware to place the device into Pwned DFU mode.
- Non-Invasive Diagnostics: Complete software and USB communication process—no motherboard soldering, chip removal, or hardware modifications required.
- Untethered Operation: Reboot freely, turn off, or power cycle the handset without losing activation or cellular reception.
- Instant Server Registration: Device identifier (ECID / IMEI) is authorized directly on the official server database for fast desktop client verification.

Prerequisites & Device Conditions:
1. Target State: The device must currently be on the Passcode screen, "iPhone Unavailable", or "Security Lockout". Devices that have already been restored/flashed to the "Hello" activation screen must use the dedicated Hello Screen service instead.
2. Hardware Check: The device must have functional hardware (clean baseband/IMEI, working USB port, and responsive buttons).
3. Workshop Hardware: Compatible RP2350 development module with USB-A host capabilities and reliable USB-C / Lightning data cables.
4. Workstation Environment: 64-bit Windows PC with official Apple Mobile Device Support and required USB drivers installed.

How to Order & Perform Passcode Bypass:
1. Connect the locked iPhone to your PC in Diagnostics, Recovery, or DFU mode to obtain its exact ECID or IMEI.
2. Submit the verified device identifier into the required order field on GrandUnlock.
3. Once your order status is marked "Completed", launch the official iRemove software on your PC.
4. Follow the tool instructions: boot the device into DFU mode, execute PwnDFU via your connected RP2350 board, back up activation tickets, erase user data, and restore the backed-up activation files to complete setup with active SIM service.
