http://androidforums.com – So the help I've got here is great but... I have the kernal DUKF2 and all the good root methods tell me to use one of chainfires kernals... but there are none listed as DUKF2. Is it ok to use say... KE7... will it break my phone... or do I have an alternative for a insecure kernal. Befuddled Sh3rlock. (General)
