So far no luck. Would you have an idea on how I would implement this on 5.1.1?

Thanks Glen, I have been building for Lollipop and the .cpp files are not in that branch. I will see what I can do to merge them in so I can make those changes to just wipe the partition on an unlock.

The host side of fastboot is open source, so you can do whatever you want to it, including adding an alias called "secret_word" or any other change. See

https://android.googlesource.com/platform/system/core/+/master/fastboot

However the device side of fastboot is often closed source, so you would need to work with the device OEM if you want to change that.

Standard implementations wipe the data partition.  If you want to modify the code to wipe more partitions, see #1 above.

I found that out the hard way. I was able to edit the fastboot.c file and setup it up to wipe the system partition but it was only working on my workstation. I had a find another work around and move on to different devices that are supporting FRP.

Hello ,
You should not edit the fastboot binary , if you do that it will only work on your pc .
You should change it in the Android Bootloader Sources platform/bootable/bootloader , and then flash the compiled new bootloader binary to bootloader partition now your custom commands will work.
But there are a lot of other things to be considered while doing this -
 If the device has been signed by oem ?
 When you do a bootloader bring-up you will also have to configure GPIO pinouts for uart / serial console.
 After this Bootloader also does the function of low level hardware initialization such as display panel . At this stage you will also have to work on panel bring up.
