Hello I am Samuel your expert. Let me get you the information!
Can you go to settings and scroll to the bottom. See if it says update system.
Did that work for you?
I have not heard of a dead build number before... What error message do you get when you attempt to update?
I don't send you those requests my job is to try and answer your questions
Ok I am understanding you now. What is the message the phone gives you when you try and update
I need to know the exact words please
I am a phone expert I have nothing to do with what You are charged sir. If you need us to trouble it would be best to use a phone other than the one in question as we need to know very specific information to give you the right support.
