UNOFFICIAL CyanogenMod 12.1 for the Verizon 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.

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.

Quote:

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!

zzpianoman knows what's up! Rom's running great, plus love the recommended apps. Data, camera, adb wireless working well. I'm able to load touch control modules, but I couldn't get "ponury stock modified" to work, causes reboot. I'll try some other ones.

Hmm. Just to verify, I am using TouchControl v2.2.1. I know the rebooting issue was a problem with an earlier version.

Is data working on this ROM?

I was on unofficial LS and did not have working data. I did a complete wipe (except for internal) and flashed this ROM with the latest nano gapps.

I do not have working data on this ROM. I had some SIM card errors on LS and I'm now wondering if I have a problem with the SIM card now!? Before I try going back to a factory image, do you have any ideas?

Otherwise the ROM runs great! Thanks for getting the camera working!!

Data should be working. I have found that sometimes after an initial boot (long boot where caches are rebuilt) data will not connect until I switch into and out of airplane mode but subsequent boots should be fine. There has been a longstanding issue with CyanogenMod ROMS on the Verizon Galaxy Nexus circa Android 4.3 and not being able to get data after switching out of airplane mode. I wrote a script that essentially monitors the airplane mode switch, and gracefully kills the phone process after you switch out of it so that data will reconnect. Just make sure you wait at least a second or two before switching out of airplane mode to make sure the script has time to register the toggle.

Hopefully there will be a more graceful solution in the future, but this seems to work well for the time being.

No Data
I haven't gotten data to work at all. Wiped data and cache, then installed the ROM and Micro GApps. I've tried rebooting, then putting in Airplane Mode then taking it off. According to the phone, there has been no data consumed at all.

Love the fact that the camera works, though. Great stuff.
