We´ve found that you can download for your Galaxy Nexus 4G (GSM/HSPA+) binary image files that are provided for use in restoring your Nexus device’s original factory firmware. This file, once unarchived, contains the bootloader, baseband, and the rest of the system. Be aware that you’ll need to have fastboot in your path, and to have the device in fastboot mode before you can use it (either “adb reboot bootloader”, or press-and-hold both volume-up and volume-down then press-and-hold power).
Be careful with this download as it can harm your device if not sure what are you doing, be sure to read all instructions before proceed.

For convenience, a flash-all.sh script is provided as well, which
restores the entire phone to its factory state.
If you’re only flashing some of the images, I strongly recommend
flashing things in the same order as flash-all.sh. Specifically, flash
the bootloader before the radio, and reboot after flashing the
bootloader or the radio.
Don’t forget that after flashing back to a factory state, your
bootloader is still unlocked. Don’t forget to lock it back in order to
secure your device (“fastboot oem lock”).
Hopefully this’ll be useful to people flashing custom AOSP builds, as
it provides a clean supported way to return to factory state.
