Here you go:
An RUU is available for AT&T M8's (CWS__001)
So I thought the grass was greener on the other side and installed ARHD 10. It's not a bad rom at all but certainly lacks the polish of IC.
I'm back and installed 4.0.0 and am very happy I did. So happy with this ROM.
I am absolutely in love with this ROM. Was on original Stock AT&T firmware for a day or so after I got the phone. Converted to GPe and liked it for a month or so, but wanted to try Sense so I thought I'd give IC a try. It's literally the best...
