Every so often Apple releases what we call a landmark firmware upgrade and stops signing older versions of their device firmware in efforts to force product owners to upgrade to the latest firmware version should they ever need to factory restore or reflash their device. The only way to reflash older firmware versions once Apple ceases to sign them, is if you have already previously saved your SHSH Blobs from the device. It is very important to have these files saved, should you wish to downgrade or restore your device in the future.
