Possible errors which may occur while running tests are:

1. Identfying incorrect certificate to a connected device. In this case, related record must be deleted and correct certificate must be identfied again.
   

    

2. If uTAFS was installed to the device before identfying the certificate, remove uTAFS manually and install again.
   

    

3. If uTAFS was installed to the device with certificate and you want to operate without certificate. Remove uTAFS manually and install again without certificate identification.
