I need help reinstalling custom tune

[Rottyfan]

Make, model and year of vehicle:
2006 Dodge Magnum RT AWD
Model #: Trinity T1000
software revision: v.1r13c

My car was totaled and I tried to uninstall my custom tune by going to Options > Erase Custom Tune

I bought back the car from the insurance company and tried to reinstall the tune. On my pc, I copied the tune to the SD card in File Explorer, but the T1000 did not detect any tune. I formatted the SD card with the T1000 and sent the tune file to tool with the Diablosport Downloader app on my laptop. I'm still unable to install the custom tune. I know I'm doing something wrong and any help would be appreciated. Thanks!

is the device married to the car?

export a copy of the stock tune/backup
then send the custom tune and show it the backup file when it asks, then it should send the tune to the tool.

Thanks. I got it.

Hey, Mike. I have the same problem. I’m not 100% sure if the device is still married to the car — is there a way to confirm that?
