IIRC Verizon uses a locked boot loader. This means you can only load software signed by Verizon onto your device. The error messages seem also to point in that direction.
Someone may correct me if I'm wrong.

Another sidenote: You mentioned Kingo. This is suspected to be malware (I didn't follow the corresponding thread, however). Seems to spy IMEIs. Search here at xda for more.
Just a warning for those reading it.
