flashing Android
the device i used is my phone, Galaxy Nexus. i started with something like 4.1.1, but that doesn't really matter. in this post, i am trying to note down only certain keywords. those who know about them may find it useful, as you might not be able to recite some operations. those who haven't known about them, can Google them as well.
