LU WiFi Tool v2.4 is a Windows utility marketed to help technicians and advanced users troubleshoot certain iOS “Hello / No Signal” activation problems across iPhone and iPad models. Built around a jailbreak-based workflow, this edition focuses on iOS 15–18 compatibility and streamlines activation and device connectivity checks for supported hardware.

Important legal & safety note: Tools that modify iOS activation, bypass protections, or alter device identifiers may violate Apple’s terms of service or local laws in some jurisdictions. Use only on devices you own or have explicit authorization to service. If you’re unsure, contact the device owner or an authorized repair center.
