These are instructions on how to extract the contents of the Spreadtrum PAC File using the SPD Flash Tool on a Windows Computer.

A .pac file is different from a standard zip file. Therefore, you cannot use 7zip or any other zip program to extract it. However, by using the official SPD Flash Tool developed by Spreadtrum/UniSoc, you can easily extract the contents of any .pac file. Furthermore, it can read and unpack the contents of the .pac file, giving you access to individual files (such as system, boot, modem, etc.).
