Apple A1466 820-00165 A

Hi, I am in my work, I installed the BIOS you edited and it did not work, the machine only works trackpad and keyboard when in the boot option, but within the system does not. Here is the original BIOS of the machine without modifications.

 

Sorry not to understand your English very much, I am using BING translator, this is the original bios of the machine without modifications, the machine has EFI lock, after cleaning and installing the system does not work Trackpad and keyboard, only works on the BOOT screen, when opens the System does not work.

 

not work

I made a video see >

 

100% this problem occurs due to trackpad sensor faulty
not related to bios or motherboard

 

I HAVE 2017 820-00165 that i tried to change the serial no to install the board to a different macbook. acidently I deleted the original bios and rewrite with known working bios which i did before. but fan spins no chime. I tried the bios you sent me early but same situation. when i pull a bios from another same board it boots but stuck in apple logo for ever.
