Basically this unlocker grabs the serial of the CPU, tells the Asus server... Gets back the necessary info to unlock, unlocks the device and leave a marker for warranty thrashing (It mentions some sort of flag), then reboots.
Edit:If anyone was wondering, the serial of the cpu would be independent of the device serial (In format 0245xxxxxxxxxxxx) is acquired from /proc/cpuinfo
Edit2:I believe the unlock server is mdm.asus.com via HTTPS, also I believe it uses the Android device ID as well.
