Failed to unlock bootloader

Hey everyone,

I have a Lumia 950XL and WPI version 2.8. Whenever I have switched the phone to flash mode and try to unlock the bootloader, after a while I get the error message "Failed to unlock bootloader. It is not possible to unlock the bootloader straight after flashing."

There seemed to be an error like this with WPI 2.3 already but should have been fixed with WPI 2.4 according to this: ... 8.3742200/

Any idea what I can try to unlock the bootloader?
