So I'm sure many of you are aware of this issue. I've encountered it twice on my Nexus 5 on both 4.4.2 and 4.4.3. Basically, if you enable/disable WiFi and WiFi Hotspot in a certain order, it breaks the tethering option and says error where it should say turning hotspot on after you click the box. Now, the only way I've been able to fix it is by doing a clean install of the factory images. Even writing the factory system, boot etc. does not fix it. Has anybody encountered this issue and found a way to fix it without wiping your phone?
