You need to send to me the dump file (BIN file), I will patch it and clean icloud ID and EFI passwords and send back to you.
fast service – 24h
You need to have an SPI Programmer to read and write on EFI SPI chip. Like Raspberry PI or Minipro TL866A or any SPI programmer.
And also good knowledge for soldering and desoldering SPI chips.
Also I have all dumps for all macbooks. I can prepare the dumps with your serial number.
If you are not experience with hardware, you can send to me the macbook and I can do the service for you, and ship back to you.
PM me for more details and helping.
