Using MfgTool after Enabling Secure Feature (Locked Device)

Hey,

I've successfully signed my u-boot and kernel, and enable the security fuse on the board. When integrating the signed images into my build I am able to use the software update perfectly fine. However, when using the MfgTool (manufacturing tool), I am unable to get it to flash the device. 

I want to know it I should be able to use the MfgTool after I have locked the device, or if I should not be able to use the MfgTool after the secure fuse is enabled. Are there extra steps that I need to take to have the MfgTool working after i have enables the secure fuse?

Also, I am using MfgTool2.

Thank you for your help!
