Those steps worked! I just had to add a step.
We run IIS so After putting that new html file into the Template.zip we followed the Toolkit machine steps and it did not replace the html in the app folder. I had to manually replace the file in the app folder and then run a deployment again and it then the toolkit machine saw it and updated.
There are also client pc's that did need the cache cleared and some not, some also needed a reboot after the cache is cleared but not all as well.
Thank you for the response
