I found out after upgrading that apparently I no longer could enable WiFi or tethering, even when using foxfi and after doing some searching found that the entitlement hack previously used no longer work either I stumbled across a post in regards to a new entitlement hack that was working for the Droid Maxx and decided to give it a try on my RAZR M and although needing to bypass step 3 as I could not locate those files listed and proceeding to follow the rest of the guide exactly as detailed I now have restored my wifi hotspot and tethering access and it is working great. I just wantedpos post to help anyone that might still be using the RAZR M and have upgraded to KitKat and lost their hotspot and tethering access.
I do want to note also, that I am also running the custom Beanstalk 4.4 ROM on my phone as I am not sure that if it matters or not.
Below is the link to the original thread I found.
Keep in mind that I had to skip step 3 because I could not locate the named files on my particular phone, but followed up everything else exactly and hotspot and tether are working great now!
I hope you this helps someone.
