Android 4.1 Jelly Bean Now Available for Rooted Galaxy Nexus

Google announced Android 4.1 Jelly Bean at Google I/O 2012 last week, but like all Android updates it will take time for a Verizon to officially release Jelly Bean for the Galaxy Nexus, but users who are willing to do some work can try out Android 4.1 today.

A leaked version of Jelly Bean for the Galaxy Nexus on Verizon is available with working 4G LTE, WiFi, MMS, SMS and everything else users would expect. This is a newer version of the leaked Jelly Bean ROM we shared last week, with enhancements and fixes.

  1. I got this to work following your instructions. However, there were 2 times after a step was complete where a message would show that “The Go Back has been disabled”. When that happened, you couldn’t do anything. You couldn’t even power off or reboot. I removed the battery, restarted, and bounced back into bootloader mode and continued. It seemed to have no ill effects.

    Thank you very much for the outstanding instructions and links.

    • Okay the reason it would say “The back button has been disabled” is cause you cycled down thru the list of items several times…to fix just continue going all the way down and it will recycle to the top again…keep doing that…it’ll say “The back button has been enabled” and you’ll be fixed. Idk why it does that either.

    • I too have the Galaxy Nexus in the UK. I don’t know if these instruction will work, I’m just going to wait for the official OTA update (it’s only 10 or so days away – perhaps 15 days if Google have to change some code due to the Apple law suit/ban).

  2. Great instructions but I can’t figure out why the referral of an SD card. Does galaxy nexus have an SD card?

  3. Good morning and thank you very kindly for putting this package. I have successfully flashed Jelly Bean to my Galaxy Nexus. I am though run into small problem though. So many updates are available but unfortunately I am unable to update…error message … “invalid package”. I followed your instruction to backup everything. Wipe data/cache, wipe dalvik cache and so on. I am regular ROM flasher so I knew that but always comes back all apps.. so this was little surprise…Have I missed something? Do you suggest that I should restore? If I do restore, will I have Jelly Bean still there or go back to ICS STOCK? I was running AOKP-Linaro ICS 4.0.4 build 38.

  4. Hello,

    Sorry for the noob question but when I open the trinity link it has 7 different kernel downloads. Which one do I select for the Galaxy Nexus on Verizon?

  5. It may be nothing, but when I installed the Kernel zip it read out “Boom” and that something was succesfully corrupted. Idk if thats a trinity joke… but now its been around 6 minutes of the trinity loading screen only…

    • I think your fine. Mine did the same thing. But the screen seems a little washed out. What kernel did you use?

  6. The top-most kernel, without the speed for the cpu posted. it just said max. I got her running. Cleared the cache again, reinstalled the zip and kernel and she fired right up.

  7. I was able to load the ROM with no issues. The only thing I have found that does not seem to work is installing apps from the amazon app store. It fails every time. Anyone else notice this or have a fix?

    • I initially had the same issue with the Amazon apps. I uninstalled the app store and just tried it again. The apps I had previously seem to be installing okay now. I’ll update if I run into problems.

  8. I had a stock Verizon phone with no tools installed on my pc. I followed the instructions start to finish and it worked great. No problems found. So far it’s great.

    Thanks to all for the effort!

  9. Hi
    Help please I followed instructions but when I flash Jelly Bean it looks like it is go to instal and than it stops and reads Installation aborted. Did I do something wrong?

  10. So i did everything as followed but didn’t install the kernel. Is that bad? I am VERY new to rooting. My phone did loan up just fine with no problems. But how necessary is the kernel and what does it exactly do?
