Restore 4.1.2 Firmware / Unbrick Verizon DROID RAZR HD - DroidRzr.com. This thread will give you two downloads, Fastboot files for 4.1.2 and a download for RSD Lite. You need RSD Lite to flash the fastboot files to your phone. If you've never used RSD LIte there are plenty of video's on YouTube that shows you how to do it...it's pretty straight forward, not complicated. My opinion...this is the only way to get your phone back into working order. I'm not sure what happen, but when you tried to use RazrUtility 1.10 to go back to 4.0.4 your fastboot files got corrupted or erased. Unless something has changed and from all that I have read you cannot go from 4.1.2 back to 4.1.1 or 4.0.4. If some have tried it and been successful then they are by far the exception. You will not have root once you RSD Lite the 4.1.2 fastboot files, but you will have a fully functioning phone. There is no know way to root 4.1.2 at this time. There are users who have root on 4.1.2 but they had root on 4.1.1 and protected root with Voodoo Rootkeeper prior to upgrading from 4.1.1 to 4.1.2. Hope this helps. Second, what operating system are you running on your PC?
