I erased the tunes and i download the factory tune and it keeps going from authenticating to disconnected. I am connect to my phone hotspot so its not the wifi problem its the device. Is there anyway i can get a mew one sent out and this one unlocked

Yes it asked me to and that failed as well so now what? The tuner screen doesnt even stay on it keeps going black

I went to flash my hatchback sport and the tune failed when downloading the tune onto the car. Now my car is in limp mode how do i fix it?
