Bootloader radio then rom is the best method. NEVER AND I REPEAT NEVER LET ANOTHER CARRIERS CUSTOMIZATIONS RUN. ALSO JUST CAUSE SOMETHING WORKS FOR ANOTHER CARRIER DOES NOT MEAN IT WILL NOT HAVE ADVERSE AFFECTS FOR YOU IF YOU ARE WORRIED JUST DONT DO IT UNTILL U TALK TO SOMEONE WHO HAS.
Edit: Also, don't trust someone when they ask you to try running the Sprint PPST.exe even though you have a Verizon vogue
