    Booting in Tethered Mode

    Step 12: First download tetheredboot.zip utility unzip the .zip file.

    Step 13: Make a copy of the custom .ipsw file that you created recently and change it’s file extension to .zip. extract the contents of this .zip file.

    In the extracted contents, look for kernelcache.release.k48 file, and  iBSS.k48ap.RELEASE.dfu files which are found under /Firmware/dfu/.

    Move these files to a new folder named “tetherboot”. Make this folder on your desktop. See the screenshot below:
