First of all Merry Christmass !
Secondly thank you for this tutorial.
Thirdly I require some help with removing those pesky ads from my kindle 4NT.
I Have followed the steps in "kindle root access via usb networking" but I'm getting stuck after activating USBnet on the kindle. I change the IP as instructed but I cannot connect to the device. I have tried to ping it and 192.168.15.244 is not on the network. Also will doing this conflict with further updates from amazon ?
Thank you !
