Your firmware did not dump properly, too many 0xFF. Please do it again, and this time verify the dump with what is on the SPIROM.

Sorry, could you upload your file again? I did unlock your file, but the forum upgrade wiped out attachments and my post.

Hi to all!

Can be posible, to do an efi firmware update manually? I've tried with Apple app without luck...
It's an a1502
0138.b15.150605072

I have a macbookpro11,1 who i revive from a water damage, i can use macos sierra normal from usb, but i can't install high sierra (yes, the firmware is not updated), somebody sells me, without turning on (only for pieces), but actually, i hopefully repair it, but don´t include the original ssd... =(, so i put an adapter.
i´ve tried to update directly the firmware with MACBRTOOL_V1.0.0_IMG, but no luck...

I've checked the list, and it appears:

MBP111_0142_B00_LOCKED.scap 82432 0142.00 MBP111 Mac-189A3D4F975D5FFC
