My Samsung S4 mini GT-I9195 turned off on its own and doesn't start anymore. I put it on flight mode last night, and after the alarm clock went off this morning, I think I turned off flight mode and then the phone turned off and now it's dead. The battery was not empty. I also tried with another New Original battery to no avail. Holding down multiple buttons to enter service mode doesn't give me any respond, not even vibrating. But when I plug it into my computer i can see a Qualcomm HS-USB QDLoader 9008 (COM30).
Is there any way to try to save the data?
How can I know whether it's a hardware problem or firmware corrupt?
