Can anyone tell me how to get mynet/3G Hotspot back in v.8?
First a disclaimer. I am not and I will not condone violating VZW's or any other carrier's terms of service, and if you follow these instructions, don't blame me if VZW catches you and tacks on an extra $30/mo to your bill.
You'll use this:
android-wifi-tether - Wireless Tether for Root Users - Google Project Hosting
Install it, run it and open the settings and change device profile to Motorola Droid X (CDMA.) Set up an encrypted connection.
Try it to see if it works. It probably won't. Most likely it'll forward you to some "you gotta pay for this waaa" page. Then Google this:
TBH_DX_Tether_Patch_1.0.zip
Flash that in CWM and try it again. It probably will. I only say probably because I don't use this myself. Just seen it around plenty of times.
