I had rooted my NC and was going fine until I restored a rom one day. And I think it had something to do with Titanium backup as well but in any case it triggered the "authorization" message and the thing reset itself back to some version of stock. I re-did my 1.1Ghz rom and it worked fine as long as I kept my wifi turned off but that wasn't making me happy I can tell you and besides all that my bn library wasn't working. It was like my nc was no longer registered. Well I messed with it and messed with it until I did something that caused it to absolutely not work. So I finally created the CWR recovery sd to blow away the internal memory and then re-did the 1.0.1 rom. This at least enabled me to re-register the device and get back to stock. I then updated to 1.1 and tried autonooter 3.0 but could *not* get it to work. I followed the instructions but after I plugged in the usb the screen remained off and *never* booted like the instructions say it is supposed to. So thinking the 3.0 was just buggy I re-did my 1.0.1 stock procedure re-registering and everything back to 1.0.1 stock. Then I tried the 1.0.1 autonooter root procedure. But crap. It behaved exactly the same as the 3.0 did. Blank screen and no booting at all after a long time. I mean at least 20 minutes waiting. But it never messed up the stock image at all. I can remove the sd card and the thing boots normally into the stock environment. So now I am scratching my head wondering why this thing will no long root for me.
