[Samsung Galaxy Nexus] Enter The Nexus:
ORIGINAL CREDIT TO BALDWINGUY77 OVER ON ROOTZWIKI. CHECK OUT THE ORIGINAL THREAD HERE

This ROM is Android 4.4.2 Kit Kat, build KOT49H. The ROM is built directly from source, that is, the Android source code published by Google available for download to all of us developers. The reason I say the ROM is "OTA-like" is because I make VERY few modifications to it, aside from the things that it takes to get the ROM working. I'll go into detail about those things below, but basically I just want the ROM to make your phone feel stable and shiny and new as if it has just received a new OTA update. That being said, it's clear that the landscape of Nexus devices is changing as new ones are released. Therefore, the other primary goal of this ROM is to keep our Galaxy Nexus as close to the modern Nexus design as possible. This means that I will also add in features that will still be stock, but will also make our phones as close to a current Nexus as possible.

As for how I handle the forum side of things, I'm always open to comments, questions, suggestions, requests, etc. I know that most of those things will often be in the form of criticism, but it's okay, I think I can handle it :) That being said, I do also have a life and am a college student, so I may not get to come on here ALL the time. I will check back as frequently as possible, and I'm hoping that you guys will help each other out as much as possible! Keep it friendly! :) So now for the details...

Everything works!

So what do I mean when I say "Everything works!"?

I'm sure by now you all know that when someone says that, it usually ends up not being true. This ROM is not an exception to that rule, but I can say that I've tested most of the things that would be expected to work in stock Android, such as...

WiFi Tethering (no subscription check)

Bluetooth streaming

Google account sign-in and auto-restore of apps and settings

Google Wallet

Location Services (pretty fast GPS lock in my area also)

Believe it or not, December is still a month!

Photosphere

Android beam

Photo editing with the new filters

Email

Exchange support

Like I said, the normal stuff (data, voice, hardware acceleration, etc.)

Installation Instructions (VERY IMPORTANT - Note: You can flash all of these ZIPs in CWM or TWRP)

ROM

1. Download the latest version of the ROM from the download post. (Also download any other files you will need to install, such as Chainfire's Superuser Root ZIP, the radios installation ZIP, the bootloader installation ZIP, etc.)

2. Put the file(s) you downloaded in step 1 on your phone's internal storage (sdcard).

3. Turn off your phone.

4. Boot into the bootloader of the phone by holding down both volume buttons and the power button simultaneously until you feel a vibration and see a large arrow that says "Start".

5. Use the volume keys to change the arrow until it says "Recovery," then press the power button to boot into recovery.

6. Because of differences in recovery types, I will make the following steps rather generic.

7. Wipe cache.

8. Wipe dalvik cache.

9. If you want to be 100% sure there are no problems, wipe data. If you are coming from another ROM or Android version, wipe data. If you do not wipe data and something goes wrong, repeat this process but wipe data - this step is not necessary if you are simply upgrading.

10. If you are updating your radios, flash FK01_FK02_Radios-signed.zip

11. If you are updating your bootloader, flash PRIMEMD04-signed.zip

12. Flash the ROM (baldwinguy77_toro_aosp...signed.zip)

13. If you are rooting, flash Chainfire's SuperSU ZIP file - this step is not necessary if you were rooted on the previous build and are simply upgrading.

14. Reboot your phone, and enjoy!

Download it noooooooowwwww: here, instant dl.

This isn't mine, if you have questions feel free to ask.

The lag can be fixed (apparently) by using a custom kernel like Mpokang.
