Here you go. Try the 3.70 tether fix. That zip file will overwrite and it should fully enable the native hotspot and native usb tether. Since you don't have 4G just use native tethering with 3G. Its not possible to tether on 4G with the native Sprint hotspot app UNLESS you pay for that feature. I believe Android tether does allow 4G tethering for free but you might want to double check on that if you are curious.

I hope that new tether fix gets you up and running again. Let us know your results.
