Due to a recent secure boot partition implemented on various international GALAXY Tab firmware loads, devices are becoming locked down and unable to accept US firmware afterwards. This is by design.
Samsung strongly discourages end-users from altering the hardware or software of its devices in a manner outside of the realm of warranty support. Samsung cannot accept and repair US GALAXY Tab devices that have been altered with non-US firmware.
