[Q] stuck at system update. topic

It's my friends phone,and during the system update from LG,the phone rebooted to the lockscreen,but the screen is not responsive to any touch,so I then was able to enter into the recovery and I noticed that the android symbol was still there and underneath it still is saying that it's still performing the system update,but it never finishes.
I'm thinking it was probably a bad download,but he cancelled his insurance from Sprint and the are telling him that he needs to pay for a news phone.
My question is there a way to recover from this?
Like running a ruu?

Any ideas would be appreciated.
