[Samsung Galaxy Nexus] Zombeezy:
Yes, a lot of the learning are the terms people use. IN the right context, you can call a thing or method by several different names and they are all correct. Such as drive, hard drive, storage, SSD, floppy drive, zip drive, etc.

Even if whatever you used to try to get it back to stock tells you different, use ClockWorkMod Recovery to:

wipe data/factory reset

wipe cache partition

advanced > wipe dalvik cache

mounts and storage > format /system

mounts and storage > format /data

mounts and storage > format /cache

Get it back to stock using GNex Toolkit at:

Then pick a nice safe ROM without issues. Nothing is perfect yet. Everybody is a tinkerer, and if they understand when you can change radios or have to add Google Apps separately, it is an easy step for them. I'm using Minco at http://xdaforums.com/showthread.php?t=1855272

Oh, and yes, the link for Factory ROMS at http://xdaforums.com/showthread.php?t=1855272 is confusing, but not if you understand this:

Verizon Samsung Galaxy Nexus - CDMA phone - Toro version of ROMS)

Other Samsung Galaxy Nexus - GSM phones - Maguro version of ROMs.

The other things such as ICL53F (Android 4.0.1) and IML74K (Android 4.0.2) only matter if you need it at the official stock version because you are returning the phone and want it look like nothing was done to it.

Really, look at the GNex toolkit. :)

SO, are you CDMA or GSM?

Are you returning this to a store in exchange for something else?

Stay away from the Factory Images for Nexus Devices page because you may, at this stage of what you know, just keep failing.

The reason I keep mention GNEx tool kit is because it is structured almost like a flow-chart:

1. Pick which phone model (GSM. GSM USA with Google Wallet, Verizon or Sprint. Any of the builds under each option are not as important as which phone model.

2. Then it goes into what also is confusing to Newbies - Fastboot or ADB mode. You don't even have to pay attention - it either shows up you device under one of those or it doesn't.

Then pick something easy like 8 (1-Click For All) or 9 Flash Stock ROM.

But, really - best success if you do this first in ClockWorkMod Recovery as I have kept saying:

wipe data/factory reset

wipe cache partition

advanced > wipe dalvik cache

mounts and storage > format /system

mounts and storage > format /data

mounts and storage > format /cache

Otherwise, you are doing a "dirty" flash or install.

This is good you are diving right in, but there is too much info out there for different sources and things will seem in conflict, which is why you are still asking questions. Forget all these until after you get it up and running again using GNex toolkit. None of these will ask what your intent is first - they just show you how to do everything or a part of everything. Even in this forum you are getting what seems conflicting info - go to this guide, go to this page.
