Installation Guide
[NOTE]These .zip files are for the Verizon Galaxy Nexus and each .zip file contains both the CDMA and LTE Radio. These radios will work on all current Verizon Galaxy Nexus roms, stock or custom, and will work with any existing bootloader/recovery. Radios are not saved when you make nandroid backups, they will persist until you change them again.[/NOTE]
[WARN]Flashing a radio incorrectly, or flashing a corrupted radio file, may harm your device, so please read the directions and pay attention when you flash: Verify that the md5 sum matches (explained below), make sure you have enough battery (MINIMUM 35% to be safe), and always make nandroid backups before you flash things just because (it's a good habit that will keep your phone safe). You flash at your own risk like always.[/WARN]
How to Flash A Radio In Recovery Mode
These radios are flashable in recovery mode, which makes them very easy to apply. To do so, you need to have flashed a custom recovery (typically this will be a version of clockworkmod recovery - see CyberWarrior's GUIDE for further instructions on how to flash recovery, make backups, flash roms, and beyond).
Step 1: Make a nandroid backup in Clockworkmod Recovery ("CWM") before you begin.
If you already have backups, skip. It's not crucial to flashing a radio, but you should have a backup ready at all times so just do it.
Step 2: Download the radio you wish to flash from Post #2 below.
Download the Radio .zip either from the phone's browser (which will save to Sd Card>Download; or download to your computer and copy over to your SD Card via usb.
Step 3: Verify the MD5 sum that corresponds to the radio you are going to flash.
I have listed the md5 sum for each radio .zip. You need to check the md5 of the file you have downloaded against the md5 I have listed to make sure that they match EXACTLY. If they don't match, DO NOT FLASH THE .ZIP - instead, try downloading again until they match. You don't want to flash a corrupted radio file, or you may have downloaded the wrong thing by accident.
[TIP]How to Check the MD5 Sum
Once the Radio file is on your SD Card, you can check the md5 sum using a file manager such as astro or OI file manager, or you can download the app HASHDROID in the market (all of these are free). Using a file manager, navigate to the radio file on your sd card, long press the file, and then check the md5 sum (the character string). In astro, specifically, long press the file and then go to Details, where it will list the sum. Using Hashdroid, open the app and navigate to the file you wish to check, then copy and paste the md5 I have supplied and it will check them for you.[/TIP]
Step 4: Reboot into Recovery Mode and Flash the Radio .zip
To reboot into recovery mode manually, turn off your device, then turn it back on while holding volume up + volume down + power simultaneously until you get to the bootloader screen (android guy on his back with his chestplate open). Then navigate to RECOVERY by pressing the volume keys, and select RECOVERY by pressing power.
Once in Recovery mode, navigate with volume keys to Install Zip From SD Card --> Choose Zip From SD Card --> Find the Radio .zip file where you put it and select the file with the power button.
The radios will install - don't be alarmed if the CDMA radio takes a minute or two
Allow your phone to boot up, then you can check and see that the new radio was applied in Settings>About Phone>Baseband Version.
To change it back just DL a different radio and repeat the steps.
