Default GALAXY GEAR: Replacing UK stock ROM with US stock ROM

PLEASE HELP...Recently I completely wiped my galaxy gear and had to flash the UK stock ROM in order for it to work. Now that I want root my gear, it is not recognized by Cydia Impactor, CMD(for adb purposes). My computer recognizes my gear so I have obviously installed the right drivers but I can't go much further than that. I was able to root me gear when I had the original stock ROM on it (US version). Is there any way to restore the US version back on my galaxy gear?? P.S I tried installing a custom recovery using ODIN and the flash only gets as far as ID:0/004>NAND WRITE START!!
