iOS 7 Tethered Downgrade

Ramdisk boot

It's time to boot the ramdisk to install the new filesystem:

Put the device in DFU mode

ipwnder_macosx -p

Send iBSS (twice) and iBEC

irecovery -f iBSS.img4

irecovery -f iBSS.img4

irecovery -f iBEC.img4

Send and load ramdisk

irecovery -f ramdisk.img4

irecovery -c ramdisk

Send and load DeviceTree

irecovery -f devicetree.img4

irecovery -c devicetree

Send Kernelcache and bootx

irecovery -f kernelcache.img4

irecovery -c bootx

If you did everything correctly you should see verbose on screen and a large ASCII "OK"
