You can install this from my repo, it is also available on Packix!
mDNSrestart relaunches mDNSResponder and mDNSResponderHelper after a successful boot. It does this through a LaunchDaemon thats set to run a script on boot (only within a jailbroken environment). The LaunchDaemon will run once per boot and never again. You can look at the log in /tmp/mDNSrestart.log to see when it was last run.
mDNSrestart was made possible by nathanaccidentally's mDNSFlush.
mDNSrestart should fix issues related to LetMeBlock & other ad-block related tweaks 15 & 17 on Odysseyra1n.
You should reboot after install to test whether its working. If the script has run, it will concatenate the current date & time after boot to /tmp/mDNSrestart.log
You should be able to compile this quite easily and run it on your device.
