Everytime I run AdAway it hang on the applying host file and most of the time will reboot the phone. Running stock rom with captain throwbacks unsecured boot. I have also tried flashing a symlink in recovery which flashes fine and then change adaway setting to the new location. It still locks up the phone. I'm now s-off & even after symlink and changed location or default location it still locks the phone. I have also tried the 2.8.1 unofficial version on xda also hang on the phone. I don't know what else to try at this point.
