Subject: [PATCH] t55_fix

  This simple script first checks if a password has been set for the T5577.
  It uses the dictionary t55xx_default_pwds.dic for this purpose. If a password
  is found, it uses the wipe command to erase the T5577. Then the reanimation
  procedure is applied. If the password is not found or doesn't exist the script
  only performs the reanimation procedure. The script revives 99% of blocked tags.
