Hey bud I had the same thing happen to me try unplugging your battery and plug it back on try putting a charger on your battery. Or even jumper cables I havent tried redoing mine since the weekend when the same thing happened to me And plug your tuner back in. I was able to upload my stock files ...

Thank you I will try while I have a battery charger on it.

Sorry it's a 2014 ram 1500 5.7l

I just brought this predator 2 7320. I read the manual and updated it. While doing the 87 tune it went in to recovery mode. After about four cycles of recovery mode it finally uploaded my stock file. Any reason why it did that. Kinda freaked me out cause the truck was dead.
