I'm getting a system dump and a mx2 over next few days to help you guys out.. I'll report something back soon.
I'm pretty sure most of the files are the same across Dx2 and Mx2, with minor alterations, the problem may lie in the Init area as well, not sure but going to check differentials. Also, someone stated Dalvik and Cache wiping, I hope he did that, I'm pretty sure I told him in PM to wipe, along with the Permissions being correct. I'm going to look into the INIT like stated and other areas that may need attention. I'll try to report back within the week or as soon as I get something updated.
