I have a Macbook Pro A1398 with a quad core i7, 2.7Ghz, 16GB ram. I bought this computer on eBay knowing it was firmware locked and did much research before buying it. I was sure i could fix it.
I was replacing the EFI chip and i wiped a resistor off the board and now the computer does not post. Since its near the EFI chip i believe the missing resistor is why it won't post.
I thought the resistors directly around it would be the same ohms, but they are not. All of them seem to be different. So i need some help confirming the ohms so i can replace it please. I have taken some pictures and made some edits. If anyone has one of these boards laying around they can test to help me find the resistance of the missing component i would really appreciate it. Otherwise i will have to spend over 700 dollars for a new board it looks like....

confirm the resistance is the same.

this is the location of the missing resistor. Im almost sure it was a resistor. It may have been a capacitor though. Please help me confirm the component and value of it. Also please excuse my spelling mistake here. I know how to spell know, lol.
