Default How to mod framework-res.apk having issues for call recording?

Hello all.
I was wondering if someone might be able to help me with this.
I am using the apk multitool and can decompile the framework but get loads of errors when I try to recompile it.
This method worked well on my s4 and other devices but am having issues with this one.
What programs are you using to decompile and recompile the framework.
Or can anyone mod it to include the wifi tethering bypass and call recording features?
Any help would be greatly appreciated
