I cannot seem to update my ZTE Score. The update downloads fine but with a space low warning. It warns me it could take up to 10 minutes but the screen just displays a triangle with an exclamation point and the little Android to the lower right of it. The only way to get the phone to respond is to pull the battery and reboot.

Also, when I have tried to implement the Cricket Backup utility, I keep getting a missing parameter error.

Any help appreciated. I am very computer literate but admit I am not yet at all swift with these smartphones!
