I took my phone back to best buy as i was still in my 14 day window.
but unless someone can confirm that they have swapped frameworks into a MJ5 base then i would change the OP to at least state that it may brick your phone if trying to do this.
as stated all the the others worked fine on MJ5 for me just not the frame work. let the people trying this know that MJ5 framework is different and may cause a soft brick.
What I could do is post a zip with framework images, and leave it to the user to install for themselves??
