In this video I’m going to show you how to use the Odysseus tool to downgrade your 32Bit Apple devices (iPhone 4S, 5, 5c and 32bit iPads) to firmwares that are not being signed by Apple anymore, if you have saved your SHSH blobs. However, if you just want to restore to the firmware you currently are, then you can dump the blobs from the device and restore to the firmware.
