This thread was made for those who tested it to say whether it works or bricked. Discuss should be kept to the other thread, this is only for people to know the working rate. All results are from these forums. The first two are from TMK(Bricked) and The Milkman(Worked), Ralan (Brick).
AS OF NOW THIS DOWNGRADER DOES NOT WORK!
This will be reopened when the time is right.
