Try this app. It makes the work for you
I'm sorry I don't know, but you can try to:
Delete iptables -t nat -A OUTPUT -p udp --dport 53 -j DNAT --to-destination 127.0.0.1 from /system/etc/init.d/dnscrypt
Delete iptables -t nat -A OUTPUT -p udp --dport 53 -j DNAT --to-destination 127....
How can I enter the IP address of the service I want to use?
Edit /etc/init.d/dnscrypt and see here
Could you please write a small, complete guide for the installation of DNScrypt? I still can't get it to work. :(
Flash this zip from recovery. It works
Use procedure in the topic with baseband LUYJP2 (flash with Odin)
