and how th f you expect me to flash annyting on windows10 via fastboot
and now to to say how can you even use fastboot w/o a bootloader .... you need a freaking bootloader to have fastboot
Listen : I'm trying to help, and I don't owe you anything. So calm down.
I don't know anything about Windows 10, and I know even less what OS *you* use, the state of your phone (except what *you* told), or anything.
What I can tell you however is that I managed to flash those .img files using fastboot and/or adb (I don't remember which one) from my Linux computer (OpenSUSE LEAP 42.1, but that shouldn't matter), and it worked. Make what you want of it, but I'm happy with what I got.
