Those of us holding on to our note 2 have been sitting back and waiting for our turn to get some 4.3 touchwiz love. Well thanks to Designgears over at xda we now have something to work with in the form of Heimdall file (for the at&t variant). With any leak or rom understand there may be risks so I highly recommend you pay attention and understand what you are getting into. If for what ever reason you do not feel comfortable I suggest you wait a little bit as the dev community will have come up with flash-able zip files through recovery. Either way cheers to Designgears as this is a big step in getting 4.3 twiz roms on the note 2. Though I know this is mainly a verizon forum, the at&t note 2 is a modem difference away so it will be a matter of tweaks before you guys see n2 4.3 twiz roms as well.
