There is a major bug with T42S. I can't get it register or TFTP provision on any of the 66.84.x branch firmwares. I had to downgrade to 66.81.0.70.

Hi,

When the firmware upgrade to v84 is completed, please reset the device to factory defaults by long press the OK button, re-provisioning it and try again.

Hope this will help.
