Hey mate,

Try this file, I had to use this to get a Fledging SSD working on a Macbook Pro that was running 0138 EFI Bootrom.

This is EFI Bootrom revision 0151 for the 820-3476 A1502 MacBook Pro 2013/4. The ME Region is clear on it and there's no passwords set.

You must us a HEX Editor to change the serial number at block 63043B, it's currently set to 11111111111 so it will NEED to be changed.

Also, within the first few boots you will need to reset the PRAM, which is holding the P, R, ALT (Option) and CMD buttons before pressing the power button and keep holding the 4 buttons till you hear the second 'bong'. This will flush any stored passwords in the NVRAM/PRAM.

Hope this helps somebody out as much as it helped me.

Thanks Friend!

Hi guys. My Macbook reports error NNN001. I don't know what the reason is. On the SN C02NRFEKG3QH housing. Can I please have a good EMC FILE with my serial number?

If you read the whole thread you`ll find some working bios versions,you just have to edit your serial number into it and modify the fsys checksum, thats also mentioned in some posts with links to a youtube video by piernov.

If you find it all too complicated let us know,but at least give it a try.

Re: Apple MacBook Pro A1502 (820-3476-A)

I entered my SN into the file but I can't deal with the checksum

I took the first file from above but it may have a different EMC than my disc. I'll make it again.
The one in the attachment is not good.

My EMC 2875
I don't know which base file to download in advance to put my SN in it. I will find the old one and replace it along with the last 4 characters from the video. However, I do not have a system to check the checksum.

Apple MacBook Pro A1502 (820-3476-A) EMC 2875 hebernation mode

Hello everyone,
I have a macbook pro A1502 820-3476 which had a Sierra High OS, after formatting it under Windows 10 it became very slow, I decided to return it as before, the formatting went well but the charging of my macbook was interrupted then I turned it on to continue the installation of Sierra OS and it finished well; but after turning it off and on again, it doesn't turn on .
after a search on the net I think it entered a hosting mode which is popular on macbook 2010 to 2014.

I would be grateful if anyone could help me resolve this issue if it is coming from the bios.

No. This is my request for help to the guys. I wrote about it a little higher. If you don't care about a specific SN in your MACBOOK, you will probably find a ready-made file in this thread. There were several of them.
