hi...
Since there was no official update beyond 2.1 for my model. Z71-
I have a rooted phone and decided decided to install a cyanogen mod

There was the procedure in the web page about upgrading but the confusing part in
Procedure .:

1. Install "Official ROM 226D" using the TOOLS (RUT or SUT-Software Upgrade Tool)

Im unable to use the SUT(ITS A PC APPLICATION) inspite of having installed it and i even dowloaded the corresponding firmware file(Official ROM 226D).

So can anyone help me in using SUT to install (Official ROM 226D)please, im really going mad trying to make it work out
