I am working on a Late 2011 MBP 17”. It gets a grey screen when I try to load macOS High Sierra (via USB). I see the apple logo for a while, then just a full grey screen. I’m reading that it’s related to the GPU issue this model has been plagued with. 1) I’ve tried entering single user mode (found some people saying you could disable that GPU and get the computer to work) but single user mode won’t boot (I tried command + r + s before turning on) 2) I also found another article where they removed a specific (capacitor?) by one of the fans, but when I look at the capacitor layout on the one I’m working on, it’s not the same. Besides a reflow, any other fixes that can be applied here to get the unit going?
A reflow is about all you can do here. If you were able to boot up your Mac and use it for an amount of time before this nonsense happens I would have suggested you to install an application that would control which graphics would be used. That application would also notify you if the problematic graphics were to enable itself.
