Restore Native AT&T Visual Voicemail on any ARHD ROM for the HTC One M8 (only works with AT&T carrier)
- S-Off is not required (S-Off is only required if you want to update your firmware to the latest version)
- Phone must obviously be unlocked and rooted
- I don't recommend using v9.1 ROM, the ElementX kernal will not be updated to support 4.4.3 thus sense 6.0 toolbox homescreen swipe commands and motion gestures will not work. I read that 4.4.4 will be out soon, so no one is really investing time in custom kernals to support sense-based ROMs for 4.4.3. You can still updated your firmware to the latest version and run the 8.1 ROM. I recommend searching for the "no red text" firmware version.
- Keep in mind that your Voicemails won't download when you're connected to a Wifi Network. If anyone has a fix for this please post and PM me so I can update this thread.
