How to Enable Native Visual Voicemail HTC One M8 - AT&T HTC One (M8)

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.

If your phone is rooted with a custom ROM such as the Android Revolution HD by mike1986 and your visual voicemail is missing, corrupt or broken, I will teach you how to reinstall it! Note, this has only been tested on the AT&T variant of the HTC One M8.
If you're an advanced user you can use the Android SDK, Cygwin and Kitchen to modify the ROM and include the following APKs:
- Phone.apk (replacement rom, newer version)
- ATT_VVM3.apk (new rom)
- HtcContacts.apk (replacement rom, newer version)
- HtcDialer (replacement rom, newer version)
- Message (replacement rom, newer version)
There are many tutorials on this site that explain how to modify and repackage a ROM.
If you want to keep it simple here's the process.
Acquire the apps listed above. Visit my website to download the APKs, just Google Trick Master PC, or you can pull them from your Stock ROM under /system/apps and/or /system/priv-app
Drop the apps on your Internal or External SD Card
Use ES File Explorer to Mount the system directory with Read/Write Permissions
Use ES File Explorer to Install the APKs from your SD location
Use Titanium Back-up Pro (yes, you have to pay for it). Browse the list of applications and find the apps you installed, long press the app and select "Convert to system app", if you have the option to integrate into ROM select that as well.
Restart the phone and set-up your native visual voicemail functionality. This process restores full functionality with zero glitches.

I was really hoping this would work, but every time I try to open the stock visual voicemail app after following this procedure, it force closes..

Yes, that happened to me a few times at first, you have to follow the exact procedure above and you have to restart the phone. As long as your phone is the ATT variant this should work. I had to mess around with it for a while, but got it working flawlessly. Restart after installing the APKs, the use Titanium Back-up to elevate the apps to system level apps. Then restart again.

Yeah I've uninstalled the apps with titanium backup and tried the process multiple times on my ATT variant running Viper ROM to no avail.

I had the same issue. What I had to do was change the SKU to 7 and the Region to 1 in the ACC\default.xml file. This also enabled the VVM button in the phone app.
However, I now have a problem with retrieving voicemails when connected to a wireless network. If I turn off wireless, everything will work fine. When on wireless, it gives an error about mobile data not being available, but it is most definitely on. It's like the messages/vvm apps aren't being allowed to bypass the wifi to check for data.
In case it matters, I am on a stock international ROM (1.54.401.5), and I also could not get the phone.apk to install using the directions above, so I installed the applications using a flashable zip.

This works 100% on the Android Revolution HD Rom for the ATT variant. The ARHD ROM is the stock rom modified by mike1986. I'm not sure how the Viper ROM was developed ie from stock ROM or from KitKat baseline ROM.
Unless your married to Viper I would highly recommend checking out the ARHD ROM, you won't be disappointed. It's an incredible ROM.

Can confirm this works perfect on ARHD ROM by mike1986! Thanks!!! :good:

Is this the version of the VVM that integrates into the HTC messaging app?

If you mean not using the standalone google play store visual voicemail then yes.

Yes, this is the app that integrates into your native Messages.apk (scroll left to view voicemails, scroll right to view all messages {VM, SMS, MMS}, and right again to view just SMS/MMS).

Interesting... just tried leaving a voicemail off wifi and voicemail notification went through. Turned on wifi and left a new voicemail and got no voicemail notification. Turned off wifi and refreshed voicemails and new voicemail notification showed up.
So, voicemail works with wifi off. When wifi is on, the voicemail app says there is no data and that it doesnt work over wifi.
On a positive note, transcribe to text works great!
I don't think it should be too hard to fix but then again, I am not a developer.

I have confirmed that everybody on AT&T, tmobile and sprint regardless of your phone type cannot download visual voicemails while on a wifi connection this problem is acknowledged and stated by AT&T, they even add the disclaimer alongside their visual voicemail stand alone app. Iphone users everywhere complain about this as well. Honestly, I never noticed the issue before, but of course who would ever really engage in extensive voicemail testing. Perhaps one day the carriers will solve this issue; although personally I believe it's an intentional move by the carriers to force their customers off WiFi and on to the carriers' very expensive data network. I mean we're talking about tens of millions of dollars per year in data charges just from users downloading voicemails over cellular data on a daily basis. No one in leadership at the major carriers would ever let that revenue slip away, not unless they had to address the issue to resolve competitive threats.
So in conclusion your visual voicemail is functioning perfectly as it should.

I believe this is incorrect. I never had these problems on the stock AT&T Rom. I will reflash and verify, but I am almost 100% certain it worked without issue.

Let us know what you find out, but all the research I did would suggest otherwise. ATT's standalone application for visual voicemail even has the disclaimer in the app store that says it won't work on WiFi. If it works for you please post a copy of your default.xml file \system\customize\ACC\
Thanks.

It did work over WiFi on the stock AT&T ROM using the built-in HTC VVM app. The app appears to be able to use the cellular data connection just like the messages app does to receive sms even when on WiFi.
I have attached the stock AT&T ACC\default.xml, but I doubt that's where the solution lies. I have tried flashing in the APKs listed above, plus the ATT AAinfo.txt, the default.xml files from ACC, CID, and MNS. I also flashed in the market.xml from the permissions folder as well as the nfcee file from the etc folder. The wireless problem still persists for me even with all of those just thrown into the ROM.
Unfortunately, that is as far as I've been able to get with this project. If anyone else has an idea, I'm willing to give it a shot.
Thanks,
JTok

I'll try to wrap my head around this problem initially I did a comparison between the default XML file and the custom ROM default XML file. The variance in the file comparison was nominal, nothing that would affect voicemail download over wifi. I'm going to use the Android development kit to run debug while I launch the visual voicemail app on a wifi connection and monitor the logs for any potential errors. Still if there are any Android developers out there who might know what the problem is it would be great if you could share it with us
