mobile

Hey guys thanks for reading and hopefully we can get this problem solved. The problem is that my pc won't reconize my phone when I boot into hboot. I've been trying to return to stock since I'm returning the phone for a replacement but I cant because it doesn't show up.
I've tried
Different cables
restarting phone and pc
uninstalling and reinstalling
Different platform tools

Another thing is that when the phone is on and connected it shows up when I type adb devices but in the hboot screen i doesnt if you guys can help that would be great, Thanks
