I also have a Note 2 and when it runs 4.1.1, this version has no issue. The new firmware with the modem inside it, its what causing it the problem. Your best bet is, as I have posted in a few section is for someone to make a back up copy of the QCN, of the original stock M919V modem file QCN, its very easy to make a backup of the QCN, with that we can reflash it in QSPST and make the AWS work, I need someone here with a videotron s4 model M919V to make a backup copy of the QCN file so we can try it out, if not we need to wait till they release a newer version. My model is the S4 but my model is i337M, but you can flash the M919V firmware because its the same modem inside it, NE1.
