2011 MBP AMD GPU died.
Found this page and tried the steps but couldn’t fix it. Followed the codings on there but don’t know what I’m doing really. But I figured out along the many tries that if I go to single-user mode and enter the code below it would put my MBP into Integrated Graphics instead of the AMD Radeon after I reboot it.
nvram fa4ce28d-b62f-4c99-9cc3-6815686e30f9:gpu-power-prefs=%01%00%00%00
So after many different tries I some how got it to the internet recovery mode and reinstalled the MacOS X. I let it do it’s thing overnight and went to bed. Woke up and the MBP turned off, I turned it back on and it goes into the black screen/white letters mode and then gray screen of death. Waited 1 hour, still nothing, I manually powered it off and turned it back on. Now back to using the failed GPU, so I reboot, single user, entered the coding, reboot, and now using integrated graphics. I rebooted while hitting the shift to get into safe mode and when it’s like 95% loading bar it freaking rebooted by itself! I have been trying to fix this for 3 days to no avail. Please help....
