mobile

So the phone I currently am dealing with was bought from someone else on eBay about 8 months ago, so I can't tell you the whole history of it, but I can tell you its problems before I dive into the download mode problem. So first of all this phone had been working fine until 3 months or so ago, and it randomly started overheating and turning off. When it turned back on, it would get stuck in a bootloop for a while and I'd leave it there to just turn back on. Ever since that happened, the phone only works for about 5-10 minutes before overheating and freezing before turning off. For a while I have been trying to get to the bottom of this, and so today I tried to boot it into download mode in order to flash a new stock rom on it, just in case the previous owner screwed with it at all, but when I got into download mode, the computer started creating a bunch of drives saying to format them. This makes me think the phone has some sort of software problem.

Thanks for the help!!
