Lol this was me a few days ago, I have the trinity. Hope this helps, it did for me
1. Power up the tool and select Options ŕ Change Vehicle Type, and put it into Demo mode again. Let it reset itself and go back to the main menu.
2. In demo mode, go under the Performance menu, and select ‘Original Backup’ as the tune to install. The tool will go through the process of “installing” a stock tune, and reset itself as if it’s connected to a car. If it was not married in Demo, it will tell you there is nothing to restore—skip to step 4.
3. Once it notifies you that the original backup has been installed, reboot the tool to put it on the main menu
4. Open DS Downloader program.
5. Once it connects to the unmarried Trinity, the DS Downloader will now be able to update the tool fully to the latest revision, and should do so automatically.
6. Once the update process is completed, the Trinity will display the main menu again. Select Options ŕ Change Vehicle Type (the first time you do this, enter a 2010 V6 car instead of a 2012) again, and enter your vehicle’s information. That will activate the appropriate firmware file for your vehicle, and you can then bring it to the vehicle.
NOTE: Since you have a Chrysler gas vehicle, if you get a message that reads "This vehicle needs an update, Download here: DCX
", DON'T PANIC, this is because the tool wants to update the vehicle’s stock calibration file, not because the tool itself needs an update. If you get that message:
1. Bring the tool back to the PC, and plug it in
2. Open the DS Downloader program and let it connect
3. The DS Downloader program will give you a prompt that it wants to download a Calibration Update to the tool
4. Follow the prompt, and let it complete the process
5. Bring the tool back to the vehicle, and select the Performance menu to load the Calibration Update to the vehicle’s PCM
6. When the Calibration Update is finished, you can then select a tune and write it to the vehicle
