There must be some script that is conflicting with your display panel. I'll have a look when I have time. And also if you didn't know, disabling post-init will restrict the functionality and the performance of the kernel.Hey pal..
Your issue happened on mine too..
I'm using LOS14.1..
Without flashing dori, boots okay..
After flashing dori, only able to go dorimanx logo..
Can't go further, and then hot restarted it self..
And me too, i'm using i9100g lcd display panel..
