What is the meaning of “flashing a custom ROM”?
What do “root,” “flash,” and “ROM” mean?
I've got Dad a Galaxy Nexus as Christmas present. Being the obsessive tinkerer that I am, I already loaded CM10.1 nightlies on it. But I don't want to take care of the phone for ever.
He's a normal computer user, not exactly a noob in gadgets, so how do I explain rooting, custom recvory and ROMs in clear, non-jargon language? Last time I tried to explain, he stopped me at custom recovery and said he's better off using what I loaded on his Galaxy Ace.
The problem with that approach is that it leaves him incapable of solving all the minor niggles that come with custom ROMs. Also, I live on campus (college) and troubleshooting online would be so much easier if he knows the basics.
