Cummins Unlock Froze at 99% for my Bully Dog GT Tuner

    November 11th, 2020

    My Cummins unlock froze at 99% for my Bully Dog GT Tuner

    If there is a battery charger connected to the vehicle, try disconnecting the charger and restart the install process. 

    Any aftermarket electronics can cause the download to freeze at this point as well. Unplug any aftermarket devices and attempt the install again.
