Why isn't my system booting properly?
First, would like to thanks ifixit for the superb guides that has helped me quite a lot these last years :)
Now, I have a pretty weird situation : MBP boots (we can hear the startup chime) but screen stays black and if one waits, the screen will become white and the keyboard illuminates, the caps lock works if I try to use it, even the sound keys can be used but still that nasty white screen (lol, can even reduce brightness on that white screen)...
Had it connected to an external monitor and tada it works but gray screen with apple and the little wheel turns on and on...
Did a AHT => nothing detected
reset NVRAM => same issue, pb not solved
safe boot doesn't work but verbose does and it stops on the following:
kernel is lp64
validation failed, data suffix : <plenty of numbers here>
Any idea on resolving this matter would be really grateful ;)
Is this a good question?
