UNOFFICIAL CyanogenMod 12.1 for the Samsung Galaxy Nexus

Introduction

I first decided to put together this Lollipop ROM using the old graphics drivers for those of us who wished to try Lollipop, but needed full camera functionality (i.e. barcode scanner apps, or any other app that uses the camera API). At this point, it looks as if the camera has been fixed to work with the newer GPU drivers. I will continue to develop this ROM using the older drivers until all of the major kinks are worked out (both DDK and non-graphics related included) and we have a 100 percent stable release. You are welcome to try my build which does offer some unique features and will continue to be improved upon and synchronized with the CyanogenMod sources.

Please note that you can NOT use any other kernels with this ROM!! I have added a number of additional features to the kernel including custom voltage, fast charge, and color adjustment so hopefully that will satisfy enough for the time being.

I welcome any and all feedback, including bug reports and feature requests. The Galaxy Nexus is my main phone, and this ROM has been stable enough to be my daily driver since I began developing it several weeks ago.

Additional Features Specific to this ROM

Instructions

First flash:
Unlock & install a recovery
Wipe data & cache partitions
Flash CM-12.1
Install the Google Apps package
Reboot​

Upgrade:
Make a backup in recovery
Flash CM-12.1
Install the Google Apps package
Reboot

If you are using F2FS, boot will hang for a bit longer on the Google Logo before animation starts.

Initial boot will take longer than it does with other 5.1 ROMS because this ROM is deodexed. My main reason for doing it this way is so that I can make modifications to individual framework files without having to flash the entire /system partition. The downside is that the initial boot after a wipe of the dalvik-cache will take marginally longer because it has to rebuild the caches for all of the system apps. If you do this while you still have a full compliment of user apps installed - i.e. after an upgrade, the boot sequence could take a REALLY long time - so be prepared for that. Personally, I feel that this is a small enough inconvenience and the benefits outweigh the drawbacks.

Disclaimer
I'm not responsible for bricked devices (honestly, has anyone actually ever bricked a GNexus?), data loss, lack of rhythm and coordination. Please remember to ALWAYS make backups before you flash and if you are changing filesystems on /data, you will lose ALL DATA which includes everything on internal storage and the recovery will NOT give you any warning before it performs this highly destructive act, so just be aware! Thanks and enjoy!

Yeah!! I was waiting for a CM12 rom based on DDK 1.8 as I wanted my camera to function properly. I'll flash it in a few hours and report back. Thanks!

Nope. Just clean flash this Rom + Gapps. Without Gapps still the same problem :/
Other LP roms works great (CM, FML, AOSP, Zmod, Dreams etc)

Did you flash any other kernels? This ROM will only work with the included kernel - any other will result in bootloops.
I have the same problem with my kernel ... with the old chip, goes into bootloop, and perhaps the fault of GCC 4.9, I did a build with GCC 4.7 and posted on the forum a while ago, you look news ... let you know, I just news ;)

Ah! That must be it. I'll build the kernel with 4.7 and post a zip. Does this only affect certain maguro devices?

So, the problem and the GCC 4.9, go safe with GCC 4.7 a user has just confirmed that it works. This issue and on all models with the old chip "VYL00M"... with the new chip "V3U00M" the kernel can be compiled fine with GCC 4.9 no bootloop :D

zzpianoman, many thanks for having ported your work to our maguro device.
I have 2 questions for you:
- does this rom have the green line at the bottom of recorded videos?
- do you plan to update LP to 5.1?

The rom automatically crops the section of video where green line is present. Not a solution, but a nice workaround.
The CM sources have not yet been udated to 5.1 so we'll have to wait until sources are updated to CM12.1

After one day using:

Positive:
-Rom is smooth and fast
-Green Lines "gone" (don't see it)
-Offmode Charging work
-Lot of features
-1080p don't laggy
-DoubleTap2Wake work *.*

Negative:
-Free ram is ~200mb so if you open sms/gallery/browser and listen music - music player turn off and after back to homescreen launcher is restart
-When 3G is ON - phone little laggy
-Recent stack laggy and sometimes have a bug with app name

Rom is Great and when management Ram maybe can be better this Rom be a best lollipop rom o Gnex :D So I can't wait for next version :)
(sorry for english)
