Root Need Help Audio Mod

[RICHRX]

Hi i need help for a audio mod wicth i think it is intresting alote but i have a proplem every time i to Flash I get a error that im able to recover from

http://forum.xda-developers.com/android/software/mod-beatsaudio-e-xloud-installer-t3029951

I whant to install the systemless version witch it need Magisk and magisk super su witch i think it is the super su v2.76
so i investigated abought the magisk and i think it does something to the boot.img.
when ever I flash magisk it gives me a boot error not a bootloop but an error masage then the LG logo then it trys to boot but its just a black screen.
Same thing happens when super su whants to update From TWRP
Could it be the root or the boot.img

So right now i have in mind that it could be about the bootloader but im not sure so before i start to experement on my phone i would like a bit of advice.

and one more thing the older version i try to Flash it Flashes but there is nothing new in the screen it says there should be viper audio eXtrembeats and the opcional addons. but that proplem should be taken to the Devs


Sorry for my grammer

SuperSU doesn't work with cm13 meaning you can't make that mod work if it needs SuperSU specifically. If it just needs root you can use the built in root thing.
