Currently, this is the only way to unlock some of these newer models after HP patched the old method. What I have found out that any model with EC prior to Feb 2014 most likely will work to unlock. That's how I've been unlocking G10s.

This is the current KBC version. Looking for 56.1E. Thanks.

Hello everyone, the KBC version of the EC file is 56.2D. Can anyone provide an EC file with version 56.1E? Thanks!
