Change serial number on 2010 Macbook Pro

I hope that I have posted this in the most relevant section and if not I apologise in advance

I have watched the @Piernov video on doing serial number change on later Macbooks https://www.youtube.com/watch?v=poA8HByYqTM and have managed, as far as I can tell, to successfully change the SN on a 2016 820-00875 board. As a learning experience I compared my modified file to one done by a friend with a lot more repair experience than me and the files are identical (files compared in Total Commander software) So next, all in the name of learning.

I just reread my question and it needs a bit of work so I will reframe it later. Thanks

Hi
Onlygood if you and your freind worked on the same exact bios. If bios was from another computer it should not be and exact match. It will have differences like in the me region serial # and so on. Just so you know from a learning experience .

Thanks for your answer, and yes it was the same file. I just worked out what I was doing wrong. I was pasting the reversed checksum in to replace the CKSM from the previous SN. What I need to do was right click the CHSM and use Fill selection then paste the hex value into the window of the popup window in HxD. All sorted now
