[NetfariousIntent]

Hello guys, i have a Samsung Galaxy A3 2016 (SM-A310F) and my stock rom is Advanced three (Ported from advanced seven for a7 2016 that is ported from note7) and i want to port this rom:
https://xdaforums.com/samsung-a-series/development/rom-a5-2017-grace-ux-t3531719 from A500G 2015.
I ported this and got bootloop.
I tried the fix with replacing the lib files.
But unfortunately this method didn't work too. Can you please help me? I don't have any ideas how to fix this.

how do we know what have you edited.
Moving everything to new Rom is not call as porting. Kernel is an issue obviously

I used this guide: https://xdaforums.com/showthread.php?t=1908008
