  1. When I press Login in HUAWEI E5577Cs-321 Unlocking App I get Can’t connect to server message so it is useless for now.

  2. Thank you. Now I get this message – “Unhandled exeption has occured in your applicaion. If you click continue the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately. The port ‘COM10’ does not exist.”

    I press continue and enter the correct boot code. Then get “Boot Shot Failed” message.
