Apple MacBook Pro Retina 13' A1502 820-3536-A Schematic...10-12-2024, 11:43 AM

Hello,
I have a macbook Early 2015 A1502 EMC 2835 820-4924-A.
Whenever I try to update the system the device dies after reboot. It only comes back to life if the battery is disconnected, and then connected again (energy drain). Apparently the firmware update fails.
I can install High Sierra normally, but I can't install a newer one.
I can use a disk with a newer system that was installed on another machine.
I've already tested another chip and another bios file, but no effect.
Boot ROM: MBP121.0177.B00
SMC: 2.28f7
I've tried the procedure... -

Hello,
I have a MacBook Air 13 inches 2014.
I have set a EFI password and I can't remember it : now I want to reinstall macOS and I can't because the MacBook is asking for the password.
I know how to remove the password with a usb programmer.
I plug the usb programmer to the motherboard and to my pc with usb, I read the EFI and I save it to a file.
Then I have to find this value in the file : $SVS because it indicate where is the password.
But I can't find the value.
I have attached the file
Thank...
