When a logic board is repaired (e.g., baseband chip replaced), the IMEI might become corrupted. Certified Apple repair centers have internal tools to re-write the correct IMEI. Independent repair shops sometimes use box tools to restore the original IMEI from a backup. This is a legitimate repair function, not a "change" to a different number.
The IMEI serves as a digital serial number used by law enforcement and carriers to track stolen devices and maintain network integrity. Global Legal Status
Some users mistakenly believed that changing their IMEI made their device completely untraceable. 3. Why ZiPhone Does Not Work Anymore

ZiPhone was an open-source command-line tool, later upgraded with a Graphical User Interface (GUI), designed for the first-generation iPhone and early iPod Touch models running iPhone OS 1.x. Core Features of ZiPhone
Modifying cellular firmware is highly unstable. A single corrupted byte in the baseband NVRAM or secure zone will permanently destroy the phone's ability to connect to any cellular network, effectively turning the phone into an iPod Touch. 2. Cybersecurity Exploits

The History of ZiPhone and the Myth of IMEI Changing In the early days of iOS modification, was a revolutionary tool. Released in 2008 by a hacker known as Zibri, it offered a one-click solution to jailbreak, activate, and unlock the original iPhone and iPhone 3G. Among its many features, the tool included a command to alter the device's International Mobile Equipment Identity (IMEI).
While ZiPhone was a miracle tool for its time, using it came with severe consequences:
ZiPhone IMEI change was a specialized feature of the ZiPhone tool
ZiPhone was a "dirty" patch. It modified the bootloader in a way that was very difficult to reverse. If the process failed, or if the user later tried to update iOS via iTunes, the phone would often suffer permanent baseband failure. This meant the phone could never connect to a cellular network again, turning an iPhone into an expensive iPod Touch.
ZiPhone was famous for its "Unlock" feature, but it also included a terminal command that allowed users to modify the device's seczone (security zone).
In virtually every jurisdiction, changing an IMEI (except by the manufacturer or authorized repair with original number) is a serious crime.
