Skyway thanks for the reply Skyway. The phone recharged just fine when I was using it before, so I guess it might have developed a charging issue while it was in the drawer for a few months, but the last time I messed with it (before today) it was charging just fine.
I have left the phone plugged in for hours just on the off chance that it would update and just now when I moved it the lock screen turned on and it has a progress bar going halfway across that says "finalizing system update" so maybe it's going to be able to update afterall.
