Hey guys, I'm in a bit of trouble. I'm trying to start up my macbook pro late 2011 (running Yosemite) since yesterday but nothing helps. He crashed because the battery was down. I plugged him in and tried to wake him and everything seemed normal, but after I type in the filevault password it stucks at a third of the loading bar. I tried it several times but nothing helps. Here a short list of what I tried: - boot in safe mode (fails) - boot recovery (holding down shift key), fails too, I never get to the disk utility window - boot in internet recovery, it loads everything then after the Apple logo there is a grey screen and the computer turns at full speed, stuck - boot in single user mode and running fsck -fy , I can get in the single user mode but after fsck command it only tells macintosh HD seems okay but it still doesn't work - I tried to reset the SMC, fails - I tried to safe boot, fails - I tried to reset the NVRAM, fails I'm out of ideas, my MacBook either stucks on grey screen or sometimes blue screen. Can you guys help me?
