Imac 820-2301-a SN problem,bios file needed please

[roy.ruan]

having a Imac, got worked on by someone else before, the guy didn't do process right i guess and put a SN that didn't belong to the machine.and that made it having few problems now
long story short, need the bios bin for 820-2301-a but can't find it anywhere, just want to see if anyone can help and back up one(if you have the board)

thanks!

What are the problems because any BIOS with any serial number should just work, as long as it is from a 2301 board of course.

yea,that's the problem,the guy put random number or whatever,its' FFFFFFFFF,something like that, can't update online now for the new OS

Just read the chip and look for "SSN" or "ssn" string and change the serial number in hex editor.

should i use the original SN or get another one? I do believe the guy previously was to unlock the machine due to a icloud lock i think. if i put back the original SN and connect to internet,it will be locked again right?

Use the original SN, no problem....
