Got it to work on my dads phone

Followed the guide but had to flash everything line by line, the script did not work, even after adding the reg-file to registry on my pc (how do I remove those lines by the way?)
Before trying one by one flash line, the phone just boot-looped.
Also glad the guide was updated with an zip that contained the fastboot driver, the fist I downloaded had not this and I was wondering where it was.
I also guess its normal that Malwarebytes sees fastboot.exe and adb.exe as an "virus, I think I saw this waaaay back when I had an android phone myself
