Edited as per your video, but not working, when trying to install a fresh installation, during verification with apple server it getting locked again. Changed serial number with one letter.
Finally edited and worked good. Tested. See attached new clean file for this model. with no password and icloud cleaned. Serial number deleted, put your first before flashing new efi chip.
i have the same MBP i mean A1278 EMC 2555 only with i7, when i tried to read it with rpi, i got an error saying no EEPROM/Flash, it has the 25q064a chip, i didn use no resistor on 3,3V, chcecked with multimeter got 4,2V i think i burnt the chip :/ cuz now the device is bricked:/ black screen / im thinking of getting new chip and program it outside of the mac, and solder it after. and question in what line of the dump do i have to write my serial number ? sorry for le bad english :> im slav ;P ... Ok i know where to put in my serial nr could someone Please upload Mbp a1278 emc 2555 i7 firmware ?? After i replace the chip i can send you the orginal ( maybe broken ) chip
You have likely overloaded the pins on the chip and it will physically need to be replaced or "piggy-backed". You need to be sure to not put more than 3.6v on any pin of that chip or inline with anything in that circuit really.
Ok the chip was gone(burnt) i found out after i unsolder it and tried to read it outside the box, lesson learnt - never trust rasperry's voltage to much, and always chceck with multimeter first:) anyways i bought new identical chip in a local shop for 20PLN thats like 4$ (pretty cheap). I downloaded the dump file of some russian website, and i found out it is much easier to look for a dump by the logic board number insted the emc nr. (i attached the file in this post) i flashed the chip with rasppery (with resistors - this time:P) and boom. Mac works like new:) hope you guys will make it to, if you have any questions, write, i will gladly help if you do to in different topics:) ... Jungle is Massive
