These are safe to flash and simply just the radio files and are in no way associated with removing root or s-off.
Installing this radio update may prompt the 2.11.605.9 OTA - DO NOT ACCEPT/INSTALL THE OTA UNTIL SOMEBODY TEARS IT APART TO DEBLOAT AND OR REMOVES UN-NEEDED FILES. INSTALLING/ACCEPTING THE OTA RIGHT NOW MAY CAUSE YOU TO LOOSE ROOT AND/OR S-OFF.
If anybody wants to host the file go ahead because i dont know how much dropbox will let me get away with.
