With Jelly Bean, there seems to be issues with different phones, radios, firmware and ROM's and it's just all a huge mess. While people who have done it before possibly have no problems, a lot of users have not. The threads that have shared ROM images have not been clear about how the update works, unless you have done it many times before.
Could someone please write a simple step-by-step guide how to update stock yakju 4.0.4 Galaxy Nexus to Android 4.1 Jelly Bean?
I am sure a lot of people would appreciate this, me included! Thanks!
