I´m a newbie in here,, hope your´ll help anyway

I´m managing a lot of the Pro8270, and have a hard time to reset them, I try´d the Network + Personal + and factory reset but thats not enough!?!
The device still tells there´s nor enough space for a system update, and I need to delete some thing,,, but how?? It´s a 14GB update!!
Please help
