Unlocking method for iPhone versions of iPhone4s and above
IPhone 4s, iPhone 5, iPhone 5s, iPhone 5c, iPhone 6 and iPhone 6 Plus can only be unlocked by replacing the baseband kit. (Baseband kit includes baseband CPU, chip and SSD. Among them, the chip stores information such as IMEI, and the SSD stores the serial number)
Unlocking method of iPad version iPad 2 and above
From iPad 2 to iPad Air 2, for the Wi-Fi version, just replace the hard disk. Unlike the iPhone, the iPad Wi-Fi version only identifies itself by its serial number. So just change the hard drive.
For the cellular version, the baseband kit needs to be replaced (the replacement method is similar to that of the iPhone), otherwise the cellular can no longer be used after replacement.
