Hello everybody, so after using JB 4.2.2 I have noticed the antenna in certain locations isn't as good as it was and the battery does wear down much quicker.
Regardless, I decided to revert back to Galaxy Nexus Yakju 4.1.2 but ONLY the radio file.
So following efrants guide, I did the following.
-Downloaded from Google developers 4.1.2, unzipped all the contents into one folder.
-I downloaded platform-tools-v16.zip
and extracted all the contents of that zip into the folder above that contains the unzipped image files.
-As I locked my boot loader before when I went to 4.2.2, I had to unlock the boot loader.
-then I did the Part D step 7, flash the radio.
-fastboot flash radio radio-maguro-i9250xxlf1.img
-one that was done, I did fastboot reboot to reboot the phone
-Phone loaded up one again.
One observation, its odd but it seems that my phone has been wiped clean, but my wallpaper that I set before doing this is still there. All my text and everything is gone but the wallpaper is there, so I'm not sure what that means exactly.
From those of you that have done this, does it seem like I completed the radio flash-downgrade properly?
I'd like to verify to be certain
