details on "fr tss ip update":
the ip address urls being used by idevicerestore, tsschecker, and futurerestore for tss are "17.171.36.30" and "17.151.36.30", both are dead.
the hex edits done to the binaries in b416862 and this commit change these dead ip's to "17.111.103.65" and "17.111.103.15".
this update of legacy ios kit will be ditching idevicererestore in favor of replacing basebandfirmware digests in buildmanifest and adding the latest bbfw in the custom ipsw itself
this procedure will be done on a5 and a6 iphones only since i will now be disabling bbupdate for all 32-bit ipads, not just the ipad 2
