In many cases, getting tethering to work on a device requires someone to hack the original, carrier-supplied tethering app, re-releasing it for users to install and use. While this works, it often takes a while for the hacks to pop up and sometimes they can be a bit finicky. Thankfully, AT&T and Rogers HTC One X users now have a simple one-clock solution that restores the original Android tethering functionality that was originally introduced in Froyo, rather than relying on a modified version of the carrier-supplied app.
Released by XDA Senior Member t0mmy, the one click method involves is quite simple for all Windows users to use. However, since it’s a .bat file, this is for Windows users and those with a Windows virtual machine only. Aside from that, however, users have reported that the method works well and has even begun discussion about other—perhaps easier—ways to unlock the tethering, especially if ROM developers want to include this functionality in their ROMs.
