Hello everyone one, this is just a question to see if it's actually possible? And if illegal. I'm pretty nifty with soldering and a customer has a mbp 2011 model and a new efi chip he wants me to put on that's been flashed to "apparently" replace this one on the mbp he has. The questions are 1. Would it actually work or would I just be wasting my time doing it for him. And 2. Anyone on here ever come a cross a corrupt efi chip that's needed replacing (as I don't think it's even possible) 3. I suspect it's because it's got a padlock logo on start and might be a "lost or stolen" mbp. So would be illegal so I should refuse to do the job? Just thoughts really. Cheers in advance.
