I'm not responsible for damage to your device as this requires root to work.
1)you have to remove htcresetnotifer.apk and htcresetnotifer.odex from system/app/ - this will allow you to edit system without the phone resetting itself
2)open system/customize/ACC/default.XML in a file editor
3)You need to find "<app name="Tethering_provision"> <item type="integer" name="TetheringGuard_Rule">1</item> </app>" its near the bottom
4) change the "1" to a "0" and save
5) I used sense toolbox to soft reset. Don't do a full reboot or setting will go back as we don't have s-off yet
Be advised this is a hack. Bugs may exist. I do know that if you turn off the hotspot another soft reboot will be necessary as the hotspot hangs when trying to turn it back on.
