If it didn't work, it shouldn't matter if he FDR's. I would just make sure its in MTP storage mode, USB Debugging is on and the Motorola cable is used.
If that doesn't help, there is another way to root using the unstuck ICS .211 tool and the RAZR Utility 1.6. It takes a couple minutes and it involves flashing the boot.img/kernel from 4.0.3, using the ICS root option in the 1.6 utility and then flashing the .211 boot.img/kernel. I used this method to reroot ICS when it was first leaked and Voodoo didn't keep root. It displayed the same symptoms as you're having like only certain apps had root access and most didn't.
