i was on NB1, sorry about the lack of info there.
i finally got it sorted out... well almost.
it turns out that flashing the modem again allowed me to get the phone back into working condition, after which i was able to downgrade to MK2
this worked fine and dandy with one issue remaining, i have no sound what so ever. no notification, music, video, nothing. wont even play music for that matter, says it cant open this type of file "mp3" even pandora wont play.
thanks for the replies.
