Looking to revamp your good ol’ Galaxy Nexus to latest Android 5.1 + root?

I’ve been looking actually for the last few weeks but finally I can say there are some Android 5.1 builds I can recommend as daily driver.  These builds aren’t perfect by any means (you may still encounter some bugs although I haven’t found any) but you will finally be able to upgrade your Galaxy Nexus to latest Android 5.1 OS and enjoy the best of Android without upgrading your phone’s hardware.

These are unofficial CM12.1 builds but they work nearly flawless out of the box, you will pretty much get all the new features of Android 5.1 and the latest CyanogenMod ROM.  For GSM and Verizon, the builds I’ve tested are nearly perfect, the only flaw I found was a laggy Trebuchet launcher, which you can easily fix by install Nova launcher from Play Store.  The Sprint version may have some video recording issues but should be okay to use as daily driver otherwise.

If you are still looking for a good Android 5.1 custom ROM for your GNex, definitely start here, try the CM12.1 ROM this week(end) and do let me know what you think!

To install, reboot into recovery, make backup ROM, wipe data/factory reset, install ROM, install Gapps,  and reboot.  (If for some reason you end up in a bootloop or get force-closed keyboard error on boot, reboot into CWM recovery, go to Mounts & Storage->format /system.  For TWRP, go to Wipe->Advanced Wipe->Wipe /system.)

    Thanks for this ROM, I’ll be installing it shortly. Will your oneplus one conversion/theme kit work on this ROM? If so, will the version with the lockscreen work?

  2. eddiegeerts says:

  3. Sebastian says:

    I just flashed this update and I got stuck in a bootloop. I tried the format/system thing and now it doesn’t even get to the bootloading animation. Any help here? Kinda urgent.

    So it worked to an extent, I didnt get the Gapps though. Something went wrong with the install of that Rom. Tried doing it twice to be sure. Anyone have an updated zip file with the Gapps. I currently have no play store lol. So any help here would be appreciated.

    Thank you!

  10. Smith says:

    Please, I might need an urgent help..

    First problem is; when I say install the CM-12.1….. file, the phone gives me a warning which says “No file context”. Inspite of this, it continues the installation and results as “script succeeded: result was [0.200000]. Install from sdcard complete.” My phone has stuck in opening screen of “Google” 🙁 I am not able to do anything right now, it always says no file found.

    However, the problem gets bigger for me. Despite the fact that I’ve made a backup already, it says “No files found” when I try to install my backup. And now as a result, I stuck in Google opening page and nothing more comes after it. It just waits in the opening screen 🙁
    Please give me a hand, I need my phone…

  11. Tim says:

    Like many of you I was stuck in the bootloop (colorful balls floating around) so did the Mounts & Storage->format /system and it didn’t seem to do anything. Went back re-install the Rom and Gapps, then robooted. Problem fixed.. phone is running Lolipop now! Hope that helps others.

  12. Antonio says:

    So I’ve just installed this on my Galaxy Nexus (int. version). Works flawlessly except for two things:

    – Screen casting.
    – Unlocking the phone thru the “Ok Google” command.

    PS: a shame that Cyanogen doesn’t allow to create new accounts, the blue logo on the top corner looks rather ugly. Cheers!

  13. Michael says:

    Can you check for updates in this once installed? i cant find the option, usually under about phone??? thanks

  14. Trianto Kontri says:

    Camera didn’t work..

  15. Francisco says:

    Hey man, thanks for the instructions and downloads. It looks like everything installed right, however, for some reason every time I go to use the search bar in the google play store I get a message that states “.” What can I do here? I have tried wiping the data and flashing completely different ROMs and GApps packages, as well as just re-flashing the links that you provided. I have noticed that At the end of GApps installation I get a “(status 7) installation aborted” message. What does that mean and could that be the problem? Thanks so much in advance for all of your time and help< you have been awesome!
