Just 2 comments i forgot:
Point 7 of instruction - tftp seetings say to run TFTP on 196.168.1.1 PC IP address while screenshot from point 6 shows 192.168.1.254; i set as 192.168.1.2.54
About firewall disabling - although i disabled mine it was not yet working, i added TFTP to approved list and beyond that i also added port 69 as opened. after this it worked.
