- do Nº 1 step, change the values and build (as told in nº 3)
- do nº 2 step, generate genesis block (as told in nº2)
You can either leave the genesis block unchanged and skip the second step or generate it, do the required changes and then build the binaries. I recommend you to do the former first, just to see it working.
ps: about the update thing, I am just asking of how to update when we talked time ago of downloading and changing the new core and upload it again, anyways, let me finish this first and then we see the rest
Okay, do one thing at a time.
