Here is the latest 32 & 64bit MiFlash that you can use in any Windows operating system higher than Windows 7,
Download MiFlash 32 & 64bit New Version
Here is your service ROM :
If your phone is booting, use “adb reboot edl” command to boot into EDL/9008 mode. If not, use key combination, while pressing both Volume + and Volume – keys plug the USB cable in. Or try pressing both Volume keys and Power key while USB cable is plugged in, you will get the port eventually.
Good luck ..
