    Is the device unlocked? It will only accept AT&T SIM cards unless it is unlocked.

    You'll need to unlock the device and get the TMobile service books.

    547 is a write failure. Could be the result of a bad file in the OS being installed, or a hardware falure on the phone. Try uninstalling the OS, and downloading a fresh copy to install, through Internet Explorer. Hopefully it's software.

    You do need to delete the vendor.xml file. The service books are part of your backup database, not the OS. You may need to selectively restore them and your TCP settings.
