This is if you want to un-cripple your mobile hotspot without rooting your phone. The "boss lady" and I use our hotspots as our separate full internet services so this is the main reason I've been rooting my phones over the years. Since it's becoming more difficult to root the latest phones this is a wicked alternative. This worked on my Cricket Stylo 3 M430 and it should work on others. Also worked on an LG V10. Didn't work on an LG Stylo 4 though.
Install an app from the Play Store called "Settings Database Editor" by "4A". This is one of the very best hacking apps I've ever used and it doesn't require root. The app is free and no ads so I'm sending this brother 5 bones because he deserves it. Read his info instructions and warning in his Play Store page.
Before you do anything with the app, attempt to enable your hotspot and let the bloody thing tell you it ain't going to work. Then close it out. This will make sure it writes a line inside the thing that says: "tether_entitlement_check_state" "5" because sometimes it's not there to edit. You could write the line yourself with the app but it's much quicker and easier to let the bloody thing do it for you.
Now open the app and scroll down "System Table" to that line: "tether_entitlement_check_state" "5" - Now tap the line and choose "Edit Value" and change the 5 (or whatever number it is-usually a 5 or a 1) to a 0 (zero). That's freaking it. Now close the app and enjoy your free Mobile Hotspot!
Btw, I just got this phone, it's on version "M43010g" and according to the LG website support page there is 1 more "Security Update" left for this, version "M43010i". Needless to say I never update anything when I have what I want working. I don't care what Screwgle says the next version does or update has. If my device does what I want it to do I ain't swallowing it, lol.
