I got an S7 edge from a coworker to tinker with. He told me that it was stuck in a boot loop and couldn't get it to stop. He told me it was in his truck, ended up getting hot and the phone gave him a warning about shutting down apps etc to cool it down. He let it cool down, then that is when the problems started. I took it home with me and tried to charge the phone. It started charging, boot-looped through the Samsung logo, than the screen went off. After that it stopped charging. I tried again today and it started to charge again. Once I let it charge for about 30 minutes tried to boot into safe mode but it didn't help. I then tried to factory reset it. Shortly into the process the screen went black and would not power on or charge again. I had to leave for work and just left it. Is the phone completely shot? It is not a big deal if it is, just curious if maybe something can be done. He already bought a new phone and this one is just to do as I please with.
