Hello shiypc,
I have tried to unlock bootloader of a Lumia 640 with different versions of WPInternals running on a W10-PC with the same result. Message says that : "SecureBoot Unlock V2" needs to be installed. Did you meanwhile know how this can be done?
Thanks

for me, reinstalling a different firmware worked as it was a model issue. you may have a different issue though as i did not get any errors related to "secureboot unlock v2"
