Franklin T9 Not Functioning After OTA firmware update

My roommate purchased a Franklin T9 on Amazon and activated it with a prepaid plan so he can play games online. However, the device received a firmware update when he attempted to power it off. Since the update, his T9 will neither boot up to the Welcome screen nor provide him mobile hotspot service. There is no help on this topic in T-Mobile's support pages. Is there a fix for this issue? Please help.
