try 
sudo apt install linuxcnc-uspace-dev

halcompile is part of the dev package.

So now I'm stuck at this step. it says git command not found....

If you are using cia402 compatible drives:

cd ~/dev
git clone github.com/dbraun1981/hal-cia402
cd hal-cia402
sudo halcompile --install cia402.comp

Been reading this for while, I think you need to reassess what you think you know compared to what you actually know.
Usually the stepper drivers are pretty hardy, the ones I have in my mill are about 15 years old and haven't missed a beat.
I've never heard of anyone having to make modifications.
Some of the early TB6600 drivers weren't as reliable as they should have been, no experience with them myself but many reports of them being that way.
So just settle down, do things the recommended way and don't try to modify things that don't require modification. And if you still insist of doing board level mods consult the data sheets for the components that will be affected. I'm sure this would have resolved the issue of "no flyback diodes".

 
I bought two 2nd hand machines with stepper system. They were pre configured for 4 axis, so I had some spares to kill. Out of the 8 drivers two or three are still working. (so I would say occasional death happens)
At least one or two I probably finished by creating a short when I was "repairing" the machines long time ago.
My guess is that the drivers were running at their limit for a long time and were a little undersized for the motors. (or can something age inside?)
The last year drivers started quitting service one by one. First by making some humming noises during machine start, then eventually stopped working.
Given the prices of new ones, not worth investigating. (but we are still talking 10-15 years, before failure)
