ok well instead of fat32 formatting and all that bs. just do this
1. get your fuze
2. take out the battery
3. pop it in, hold power button and volume down button at the same time.
4. you should enter boot loader, on the bottom you will see something that says
5. plug in your usb cable and you will see it change from "serial" to "USB"
6. you are now ready to flash, run the custom ruu like normal and once it begins to search your phone it will detect it like it normaly would in activesync.
7. flash your custom rom and boom! you are done.
pretty easy ey? let me know if you have any questions
