I followed the steps exactly and when the phone booted after the radio upgrade I got stuck at the Verizon logo screen. I followed the instructions- once again- and I noticed that when the phone was booting with the first Verizon logo the text at the bottom looked jumbled & scrambled. I thought that I had bricked my phone - even risked my life in a blizzard to go to VZW to get a new phone but they were closed due to inclement weather. I got home and decided to google a Verizon stock radio and came across a link for a 1.4 radio.
