In the unlikely event that your TA fails to respond to AT commands
after upgrading the flash EPROM follow the procedure below:
1. Power on the TA. The reset will prompt the TA to check the

2. If proper valid firmware can not be verified, the TA will initiate
Kernel Mode. Once it is in Kernel mode, you can issue limited
"AT" commands. From this point, you can start from item 3 of
our upgrading procedure.
