How can I exit download mode?

[AC Question]

Hey guys, I really hope you can help me,because I have tried everything already. I have a Galaxy S4 which I have rooted a week ago. I tried dr. Fone recovery (free trial). My phone responded to it and it's now in dr. Fone recovery mode, but in the program it says that my device can't be detected. The problem is I can't get out of that mode and into my phone. I've tried holding all buttons at the same time,restarting,drained my battery and it still keeps going back to that screen. I don't know what to do. I need to get into my phone to back up my things. I regret using this useless program. ''My computer'' doesn't detect my phone anymore
