ShadowRegret

I tried like 5 cables and went to the diesel shop here an got nothing I even used their tuner cable and it didn't even make a sound on their computer? All I get is the red light inside the box

Mine doesnt even beep it only had a red light that you can see if you look threw the plug on the other side.

I just re did step 1 and didn't restart before step 2 I did step 2 right after 1 right clicked and ran as administrator. I still get no sounds when I plug in my tuner but got devcon failed again.

I tried a bunch of cords and non of them made it make a sound even on another computer. But there is a little red light that comes on in my tuner. I got all the correct tuner files for xzt I got them from quadzilla. But I still cant get past devcon failed

I will try again tomorrow but when I plug it in my computer doesnt make a sound or anything. The tune does have a little red light that turn on in the inside of it. I'm unsure what it is but I cant seem to get past the devcon failed

can anyone help me with my quadzilla. I got a xzt and been fallowing these steps and have been all over these fourms. when I do step 2 I get devcon failed I tried all sorts of cords and such but nothing seems to fix it. im using the software quadzilla emailed me a couple days ago looks the same as yours. I don't get what im doing wrong I did step 1 a few times
