Need Bin for cr-10 with v4.2.7 new board

I don’t really know much about these printers and still learning my own. I’m trying to help my son with special needs.
we had to buy a new board… was told to buy the 4.2.7 never done this before.
we have old computers. So - cant connect. We just need a bin file
for the Original Cr-10 with CR-Touch The HEX file wont work for us.
I used this site to upgrade my ender 3 and it worked flawlessly.

is there anyway that I can pay extra for some help with getting a bin file sent to my email?
It’s been a week now that he hasn’t printed with his machine. Thanks
