Because I don't have a compatible usb cable where the computer will recognize the phone.
Well, without one you're not going to get very far I'm afraid. There's no magic to this. In order to fxz back to any useful release, you'll need a working USB cable, latest moto drivers installed, and RSD Lite to be installed. The fact that the 905 update doesn't work for you means that your phone is in a bad state (i.e. the frozen apps thing). I have no idea if a factory reset will fix that or not. If you're seriously considering going to an ICS leak without a way to flash the phone I'd think twice about it. That's an absolute recipe for disaster....especially since you'd be off the OTA path without any way back.
Am I going to HAVE to fxz back to a release. These leaks are pretty stable from what I have read. It's just that the motofail cable that came with my phone was busted and now the two other usb cables that I have from verizon won't work. I have to dropbox everything, it's frustrating to say the least.
I'd say you're never even going to get that far since you deleted and froze system apps in 902. So, yes, I'm fairly certain you're going to need to FXZ to even start this ride.
Point being have you ever used rsd lite or an fxz file?
