After upgrading the 16GB iPhone to iOS9 or above, you will find 16GB storage space is not enough for daily use. Actually, it’s not a good way to delete apps or clear photos/music to solve this issue.

- The hard disks of the Apple iPhone 6/6 Plus are supplied by SKhynix, SanDisk, Toshiba and etc. In order to expand the iPhone’s storage space, you need to use a new hard disk to replace the old one.
Here, someone would like to ask why it’s possible to replace one hard disk while the hard disk, baseband, chip, and fingerprint are closely connected. Then, Of course, you need to replace a set of chips through the traditional method. But now you have to replace a simple hard disk with the help of a novel box which is able to read/write hard disk’s IMEI.
Apple will allow the iPhone’s activation if the hard disk’s IMEI, iPhone IMEI, fingerprint and CPU match completely. Each hard disk has the unique serial number, so you only need to write the IMEI of the old 16GB hard disk into the new 128GB hard disk.
