820-3787-A stuck at halfway loading bar

[shlom]

hello
820-3787-a stuck at halfway loading bar

no liquid damage
can't find damage under the microscope..

when i try recovery mode also doesn't load to the recovery,
but stuck with the apple logo and halfway loading bar...

also without the ssd...

seems like doesn't detect the ssd, but could be because the board efi has not been updated to support high sierra yet..

any ideas?

Run ASD EFI version first. Was is already messed with? Especially GPU area.

hi

on the build in diagnostic it reports no issues...

doesnt seem like it was messed with...
it has something looks like red glue supporting the gpu corners, but could be the original...

sorry for the question...
but where can i get ASD EFI image for this model?

thanks..

Check this file and search through Internet for correct model of your machine...

Picture pease? Apple never used red edge bonding for the GPUs.

Yeah if there is red edge bonding, someone has replaced the GPU. I've had a few like that I refuse to mess with them
