Re: A1278 820-2565-A EMC 2554 Clean Bios
Update: I tried removing keyboard flex ribbon and press the power button VOILA! it works! I am posting this update using this same Macbook Pro, with USB keyboard.
Every time i turn it on i have to use SMC Bypass method. (With the magsafe disconnected press and hold the power button. While continuing to hold the power button plug in the magsafe connector. Continue to hold down the power button for 5 to 10 seconds. Release the power button and wait a couple of seconds. Now press and release power button.)...

I just bought this from a guy online who is leaving out of the country, bought it with out hardrive, battery and memory. I checked the board looks clean too no sign of water damage. Can you guys give me test point where i need to check for proper voltage, resistance, etc.
Edit: I tried booting on refit efi menu selecting terminal playing some cmds & just leaving it in there and its like nothing is wrong going on. Its stays powered on for long time.
Is it still considered as SMC issue? or Bios issue? Do i really...Last edited by p0lyX0r; 04-17-2019, 04:33 PM.Leave a comment:

Re: MacBook Pro Shut down after Bios Unlocked
Thanks for reply, ohh a typo error, correction its A1278, but for board number its correct 820-2565-A.
1.Downloaded here a 2554 - 13 MBP 2012 i5 2.5.bin (AFAIK posted by Polytek & it is clean,unlocked.)
2.Copied my serial from my backup .bin also copied the hash C072
3.Replaced the serial and hash of the .bin file i downloaded.
Is this what you mean to say ME region? If not can you share here how to do it? And anybody can share clean ME dump?
Thanks in ad...Last edited by p0lyX0r; 04-16-2019, 01:58 PM.Leave a comment:

MacBook Pro Shut down after Bios Unlocked
Macbook Pro Mid 2012 i5
Model: A1287
Mobo: 820-2565-A
EMC: 2554
Bios: MX25L6406E
Using CH314A tried auto detect chip and it detected as MX25L6405D instead of MX25L6406E. Still i insist selecting MX25L6406E as i know the markings 100% indicated on chip.
Programmed successfully, Verified Successfully, after installing back to the Motherboard. First it POWER ON for about a minute. while im trying to install fresh OS it suddenly shut down. I did SMC and NVRAM reset too, but still having this issue.
Any help? -
