After reading through the G2 forums I found this and it also worked for the T-mobile G Flex.http://xdaforums.com/showpost.php?p=51213845&postcount=43 I couldn't get the other method posted here to work at all. All credit goes to xda member mrgodai. Follow the instructions in the link provided and a script will automatically change the value to 0 on boot. You will still need to change the user agent to something mobile or in my case Safari browser. This only allows you to go over your tethering limit. If you don't have unlimted data then this will only work until you reach your data cap.https://chrome.google.com/webstore/detail/user-agent-switcher-for-c/djflhoibgkdhkhhcedjiklpkjnoahfmg?hl=en-USAlso make sure to edit your APN scroll down to the bottom where it says APN protocol: and make sure it is IPv4 not IPv6 and add "dun" to the line for APN type: default,supl,mms,dun
Outdated method below
Prerequisites
1. Rooted T-mobile G Flex
2. SQlite Editor app($2.99) probably a free alternative out there
3. Hotspot Widget from Google Play
Instructions
1. Open SQlite Editor look in - /data/data/com.android.providers.settings/databases/settings.db then click global scroll down to field "tether_dun_required" edit the original value set 1 and change it to 0.
Note: Every time the phone reboots the original value defaults back to 1 so you will need to change the value back to 0 every time the phone reboots.
2. Only enable tether through the widget that you downloaded earlier. For some reason if you use the official t-mobile widget it won't work.
3. I don't have a working G Flex to test but you may have to use UA spoofer for chrome and set the browser to safari or something mobile.
