    Apple MBP A1398 EMC 2881 820-3547-A

    Hello Guys, my MBP Mid 2014 A1398 EMC 2881 with a 820-3547-A Logic Board has a locked EFI N25Q064A.

    I did save the .bin File, but i am having trouble finding the serial number and paste it into a clean dump or deleting the lock.

    Could someone help me out?

    Thank you very much!

    Additional info: I am missing a clean dump, just found it on pay sites. Furthermore i can't find my own serial number by searching for 'hwc' or 'ssn'. Did i do something wrong?

      the posted bios is not ok..make a copy and post again..remove the bios chip from the motherboard before reading or writing ..

        I can't remove the bios chip from the motherboard, as i do not have soldering capabilities.

        I connected a cable i bought as a bundle with the ch341a, but i need a soldered power supply, right?

        Is there a way to figure out if it's the 1.8V or 3.3V version?

          Which cable ,is it a J6100 ,post a picture. Try alternative CH341A software, you`ll find ASProgrammer,Colibri and NeoProgrammer all on the forum.

            Yes, i think it's a J6100. But if i need an external power supply it's really getting difficult for me. Tried ASProgrammer and NeoProgrammer already, but i will go on. Please find two pictures of the bios chip and my setup attached.
