Here is a guide to use RSDLite to install the .246 ICS FXZ that I cobbled together from various post.
Credit goes to those that wrote the original & host the links. I just amended it a little & put it in one place to make it a little easier to use & find.
Hopefully this will help those trying to get there 246 ICS issues worked out.
This will put you phone back to just like it would have come from Motorola with 246 ICS on it.
You can use this to install .246 over any version you are on.
You can't fxz back to gingerbread from the .246 ota (or leak 235 and above) trying to do that will brick your phone.
This will wipe everything but your external sd-card.
Back up or move anything you want off the internal sd-card / Memory.
