I have a TF300T running Android 4.1.1. The firmware is JRO03C.US_epad-10.4.2.20-201212028.
I'd like to upgrade to Android 4.4 KitKat.
What is the correct sequence of steps? Some of the posts I read say that the device needs to be unlocked first by downloading a utility from Asus, but I don't see an unlock utility that's made for this firmware version.
Also, I don't have a USB cable for the tablet. Can I flash from a microSD?
Thanks in advance!
