sending M122 I got the response, Emergency Stop! Reset the controller to continue.

It sounds like you send M112 instead of M122. M112 is to restart the firmware.

I managed to fix the printer, It had deleted it's config file and I was able to find the original file for it to replace it. Thanks for the help guys.

Glad you got it sorted out!
