Hey everyone I'm in need of some help and or experience. I recently bought the trinity and went to tune my Silverado I plugged into the obd2 the tuner booted up and went through normal steps. once original was written to trinity it would run the new tune loading bar then came back saying could not install tune restore original. I went to restore original and it would not do it. tried to re install again. nothing. truck now stuck turn key only get electrical. what to do now??? thanks in advance for any help. also I did not do any updates or anything to it.

do you have an aftermarket stereo?
if so you need to unplug the harness that ties it into the factory harness and then try again.

yes I do, I will try that this weekend. I'm just scared that if I do it and it doesn't work I'm stuck without my work truck again and cant afford to get a new computer again. worse case scenario if it doesn't work again what would be my next plan of action? thank you for the advice and help, this is the biggest reason I choose your company over any competitors. id also like to add the other truck I have a unit in has worked perfectly since day one (2002 2500hd 6.0l)

make sure anything aftermarket (non-factory) is disconnected/pull the fuse for - anything like aftermarket stereo, subs, amps, nav, alarm, remote start, seat heaters, trailer brake/light setup, etc.. anything like that, their wiring harnesses need to be disconnected/pull the fuses for it before you try to tune anything...

also make sure everything is turned off inside the truck.. lights, radio, heat/fan/blower, do not operate power windows, put your parking brake on, etc...
