ThunderBolt eHPRD settings

We'd hoped to give Verizon's network a couple more days to settle before breaking this one on you, but these are drastic times, folks. See, more than a few of you have had issues with getting 3G data on the HTC ThunderBolt when you're in a non-4G area. Nope, doesn't make much sense. But landle in the Android Central Forums has done a nice job explaining how the TB uses the eHPRD 3G network to speed the handoff between 3G and 4G data. Problem is, it ain't working for a lot of people.

Good news is there's a fix -- no hard resets (which until now had been the recommended fix), human sacrifice or other unpleasantness. Here's what you need to do:

  • Go to the ThunderBolt's phone dialer. Enter ##778# and hit Send.
  • You'll get a pop-up labeled EPST, with the choice to "View Mode" or "Edit Mode." You want "Edit Mode."
  • You'll be asked for a password. It's 000000.
  • Now flip down to "Modem Settings," and then choose "Rev. A."
  • Change the setting from eHRPD to "Enable," hit OK, then press the Menu button on the phone and tap "Commit Modifications."

That's it. You're done. The phone will reboot (don't worry, you're not losing any data here), and things should, you know, actually work. As landale points out, you'll want to change this setting back once Verizon gets its network sorted out. But in the meantime, enjoy your, erm, new 3G! [Android Central Forums] Thanks, landale!
