help with crc32fix

Guys help me please, crc32fix doesnt work for me. I did everything correct, but when I try to fix the bytes of my new iwi it just stays different. help someone please

When it says to paste 00 bytes four times, DO NOT replace the old ones. You're supposed to add it in.

still doesnt work, i did everything correct in hex editor but crc32 just doesnt do anything the at all
