I have a Virgin Mobile LG Optimus F3. Today I noticed it was prompting me with respect to a major system update, informing me of the need to have a full battery & use Wi-Fi because it's a large update, etc.
In other words:
"A system update is ready to install. Your Android device will restart and install the update. You won't be able to make any calls, including emergency calls, during installation."
What is this update for? Is it one I want? Is there a way to back up my phone the way it is right now (the current version is 4.1.2 LS720V6), like you would using a "system image" backup using Norton Ghost or Acronis on a PC, so that if I don't like it I can just return it to its current state? (My guess is "no, unless you root it," in which case--okay, what root ROM etc do I want, and can I download a 4.1.2 V6 "stock" ROM?) If I just want to stay where I am, is there a way to have it NEVER AGAIN as in NEVER prompt me for this again unless I have it specifically CHECK for updates?
