Did you install the python application properly? Without running the flash toll, you will press and hold the volume down and volume up keys of the phone until the download is complete..This is a sequential process, if you miss one, you will not get the result...Finally, on a PC with win 10 installed, the field is very difficult, it causes problems in loading inf files, and you will disable signatures on it. I am writing from the translation, the explanation may be broken

Redo the Brom steps. It's either you did not pass BROM or pass with error msg ( if it is, give ss of the error msg )
