I used the Root De La Vega process on MI9 and then installed safe strap once I confirmed Root access. I then installed Dynamic Kat in the main slot and have rocked on since. If I can be of further assistance, please let me know.
Best of luck and read, read read before you start. I usually print instructions the first time I do this with a new phone so I make sure I get everything right.
