Need to reset WP7504


I was doing some testing on WP7504 using development studio on windows. I used the tty serial api without sandbox. After power cycling the board, the WP module stopped enumerating the COM ports (except the DM port) and now I can’t connect to the module.

I tried to reset the module to factory setting using the both wizard and swiflash. Neither was successful completely. Attached screen shots for the attempt.

Any idea how to solve this? Is the module damaged?

Please help. Best regards,
