To start I am a newb
I Have a galaxy nexus with the 4.1 Jelly Beans ( not stock, installed via ROM from here xda). That's fine. This week a new "system" update was available for my phone. So I downloaded it and the phone reboot, when the phone starts it goes to the cwm recovery screen saying the update failed. I would like to have some HELP, I found other threads, but I really don't want to do anything worng.
How can i get the updates to work again?
DO i need to get ICS back to update the phone?
How should i do it?
Can I do that without losing my data ( would be great, but i am ok if there is no way)
I am just afraid if i go back to ICS, and the update don't show up.
