                    Good evening. Macbook a1534 emc2991. Failed update, stuck after shutdown, internal memory is not detected. The volume is 512GB. It works fine with an external drive, when you try to update, you see license errors. I'm thinking of flashing EFI Bios. if you can help. Serial Number CO2SC1CAGTHV

                          try .. but be careful when writing because the bios posted is longer... remove the bios chip from the motherboard, before writing or reading, or stick wires between the programmer and the chip..

                            Thank you very much. I managed to upload the BIOS without errors. Startup there is only WiFi stopped working. But the internal disk is still not visible in the system. The personal macbook was practically not used. has 35 charge cycles only. Is it possible to drip only the CPU further..... All resistances are normal. SSD power supply present
