Default [Q] Hotspot apk mod Help Please

Curious if anybody can help. I've read and re-read the Hotspot apk Mod forum over and over again and am having problems making it work on my LG G2. I downloaded the mod and backed up the old files to sd card in root browser. Cahnged file names, copied back to system and rebooted. When I go into the hotspot and try to turn it on I get message Unfourtunately com.lge.mobilehotspot.ui has stopped. Any help would be greatly appreciated. I'm new at this
