TF700T won't upgrade from 4.1.1 to 4.2
Hi guys! I'm a brand-new owner of a refurbed ASUS TF700T that I bought from NewEgg. So far I love the device, the display, and Android -- this is my first Android device.

I noticed that it came with Android 4.1.1 and would like to upgrade it to 4.2. I tried the obvious route but when I do a "System Firmware Update" it says "There is no update for your device currently."

I thought that 4.2 was already available for this device. How do I upgrade?

If it helps, here is the system info.

Android Transformer Pad TF700T
Android 4.1.1
Kernel version 3.1.10 android @Uranus #1 SMP PREEMPT Thu Sep 27 2012
Build number JR003C.us_epad-
Pad EC version PAD-EC20T-0216

Thanks in advance for your help!
