I have recently bought a K2i that I just modified to run the 3.2.1 firmware. Since I've never been able to register a K2 that's been modified this way, (I am told it's a inherent flaw to this modified firmware,) I have tried repeatedly to use the reginfo hack in order to try and enable the Kindle to create collections. Every time I try it, the hack fails and I think it shows the error 007. I am hoping that there is a solution to my problem. I would appreciate someone's' help with this matter.
