Don't be nervous. My second one was fine.
[Verizon HTC One (M9)] sidjohn:
Thanks to [MENTION=5618158]bschram[/MENTION] I'm back in business again. Unlocked and S-Off and Confirmed Advanced Calling / VoLTE working.

I think I may have had the VoLTE issues from the start on the original M9 as I remember not being very impressed with the HD calling - just probably didn't use my phone in a way that made losing VoLTE an issue.

I did notice a much crisper, clearer sound quality on the call I made today on the new handset. A very definite improvement.

Time to dip my toe in again...very carefully!

Thanks everyone.

************Update

Couple days in with S-Off on replacement device and all is good.

Upgraded FirmWare to 2.6.605.10 and flashed Fluent - VoLTE working as expected for me.
[Verizon HTC One (M9)] Dstu10:
Out of curiosity, can you set up "OK Google" Detection from any screen? I had t send my last phone back do to a vibration not working, but VoLTE was not working either. One thing I noticed was that I could not setup OK Google detection either. Not sure if it is related to the VoLTE, but if you are unable to set it up, it might help tell us something. I think it said my language was not supported even the I was on US English.

Yes. Ok Google is fine. Like I said the loss of VOLTE is not a bug deal. People don't really talk on the phone anymore and I am on WIFI 95% of the day.
[Verizon HTC One (M9)] bschram:
OK Google detection wouldn't have anything to do with voLTE.

Are you still on Fluent, or are you unable to set up OK Google on stock after an RUU as well?
[Verizon HTC One (M9)] Dstu10:
Im going to run the stock RUU this morning and see what happens.

Ran RUU and advanced calling is back. Im going to update firmware and see If I keep it.
[Verizon HTC One (M9)] sidjohn:
My phone indicated same but Advanced Calling wasn't working for me. Settings were as they should be but the device was just not co-operating.

I believe another indicator is having "Temporarily be able to turn Video calling off" grayed out under Settings==>Call==>Video Call. I assume that means the video calling part of Advanced Calling isn't working

I would verify by placing a phone call while in solid 4g coverage and attempting to browse to a website as suggested by [MENTION=3472611]dottat[/MENTION]
[Verizon HTC One (M9)] Dstu10:
Video calling and Volte working. I tested with my S6 work phone. I will flash firmware and fluent rom and test. dottat seems to be correct in saying remove advanced calling from MyVerizon, turn off phone and RUU back to stock.
[Verizon HTC One (M9)] PrizmaticSmoke:
Just wanted to add my experience to this thread as reports of this seem to vary so much.

On stock 5.1 and prior to any modifications, advanced calling worked fine for me. I went s-off via the clip method, installed TWRP, ran some backups, then flashed SuperSU to root, and unlocked the bootloader. Then I also installed AdAway, and poked around in a couple of the system folders (just looking at .png's for system icons and such).

I maintained advanced calling after all these modifications and had no issues with it for several days.

Then I decided to flash a new ROM, so I did a full wipe in TWRP (system, caches, and data) and installed the LeeDroid ROM. Apparently the version i flashed (i believe it was R39 but couldn't swear to it) did not have verizon support, and i never successfully connected to my network.

After trying fruitlessly to get it working for a bit, i wiped again and flashed Fluent ROM. Everything worked great there, except for advanced calling. The option was still active in settings and on my account/My Verizon, but it did not work. Toggled it off on my account, waited 20 minutes and rebooted. Then reactivated it from the phone, waited 20 minutes and rebooted. No go.

So i restored my original backup - went through the same steps again, and no change, advanced calling still not working.

I then turned it off on my account, and RUU'd back to stock. After getting booted up, i once again activated advanced calling from my phone, waited 20 minutes and rebooted. Same thing, appeared to be active in settings and was turned on in my account, but it does not work. Took the OTA, didn't change anything.

So it seems to me I've lost advanced calling permanently as others have, and it seems the loss did not occur until i flashed a ROM. Could be the act of wiping in TWRP that did it, or flashing a ROM without verizon support, or maybe flashing a ROM period. But i don't think S-off or rooting alone causes it, as i maintained advanced calling until i wiped everything and flashed a new ROM.

By the way i'm not that worried about advanced calling feature, so probably won't bother with exchanging the device any time soon. Just wanted to relate my experience with this. Back on fluent ROM and loving this device much better now with root and some simple mods, even with the loss of advanced calling. :)
[Verizon HTC One (M9)] kiniku70:
I'm in the same boat and VO-LTE (simultaneous) voice/data matters to me

The ROM developers are a bit mute on this issue so I want to help out those that are considering this and give everyone a warning if you are considering S-offing your Verizon M9 to use their ROMs. You WILL lose your "advanced calling" features aka VO-LTE which includes HD Voice, simultaneous voice data through the carrier, and video calling.

Some of the ROM developers don't mention this possibility at all, where others are vague with words like "some", "maybe" etc. I guess I was hoping I was going to be out of the minority. But that didn't happen. I even posted on one of the bigger developers forums where I got the ROM asking for advice and they pulled my post. Some of you may not care about Verizon's advanced calling features. But I do. Be warned!

I am going to take my M9 to an area Verizon support center and plead my case. I'll let you know the outcome.

[Verizon HTC One (M9)] bschram:
You are exaggerating here when you say that you WILL lose voLTE/advanced calling if you flash a ROM.

It is a problem that occurs regardless of ROM for a minority of users. For most people, voLTE is NOT affected.
[Verizon HTC One (M9)] dottat:
What means did you troubleshoot with?

Also, a blanket statement like that is garbage. I had an affected phone. I replaced it. I flashed more roms and firmware and did more kinky stuff to my phone than most xda users would and the second phone still has volte.
[Verizon HTC One (M9)] kiniku70:
Well you have two people in this thread that lost it. So marginalize it all you like but clearly it is a verified risk.

I'm not going to argue this. I'll let the forum know what happens from here.
[Verizon HTC One (M9)] dottat:
What troubleshooting steps did you take?
[Verizon HTC One (M9)] bschram:
There's actually more than two people in this thread that lost voLTE. That doesn't mean that it happens to everybody.

If you have any ideas on how to solve this issue, we'd love to see it, but simply fear-mongering trying to get people to not flash ROMs isn't going to help anything.

We have not done anything to hide what is going on. The existence of this thread is a clear acknowledgment of the problem, and gives the current best solution.
[Verizon HTC One (M9)] michaelbsheldon:
That's correct: I had to call Verizon once just after getting the M9 and have

them stop and start it from their end.

Have jumped around on different roms almost weekly - stock and Fluent,

and voLTE stays 'on' every time.
[Verizon HTC One (M9)] kiniku70:
resolved

I need to apologize for the misinformation I posted.

To back track, I had bought a new Verizon M9. It was S-OFF'd and then I immediately activated it at the Verizon store. I then ROM'd it with one of the more popular ROM's from this forum and everything was working fine -except of course Verizon's advanced calling features. So after my last post I restored my original Verizon recovery. I was then able to hit the "activate" advanced calling button in settings, I tested it with my friend and it works flawlessly.

I am a bit leary to re-ROM it since I now have everything working. But I suppose I could restore factory again if I lost it. But for now I think I'd just going to give the Verizon Rom a spin for a while.

Admin if you would like to remove the start post to this thread feel free. Again apologies to all.

[Verizon HTC One (M9)] sidjohn:
Update from OP

Seems like a good time for me to chime in with an update.

My first M9 did lose VoLTE and while I assume it worked when I activated the device, I really can't say for sure that it worked to begin with.

I have done most of the same rom and kernel flashing with my second device and haven't encountered any issues that I couldn't recover from - everything still works as advertised.

I have temporarily lost VoLTE a couple of times when experimenting with Xposed and Sense Toolbox but restoring a nandroid always brought it back. Since I've not seen others reporting similar experiences with Xposed, I would put that down to user error on my part.

There is always risk when we tweak deep into our devices and since the Verizon M9 community on XDA is relatively small, we don't have the benefit of widely reported issues. We do, however, have some very knowledgeable and helpful members who will go a long way to help trouble shoot and resolve our issues where possible.
[Verizon HTC One (M9)] Slacker101:
So this is kind of strange. I had issues with VOTLE and I was working with [MENTION=3472611]dottat[/MENTION] in order to resolve them. I was on fluent ROM and had never started VOLTE before. It didn't seem to want to work. So I restored a nandroid of 5.1 stock, reset it online to disabled, enabled it phone side, and it worked. The only weird thing was the phone kept rebooting itself, no biggie I thought, I'll just restore the nandroid of fluent like I planned. After doing that VOLTE did not work. So I thought hmm, maybe nandroid does affect it. I retried my previous en devour since [MENTION=3472611]dottat[/MENTION] suggested that a nandroid would not affect it. This time, it took and I have HD calling from fluent mod, without ever going back into the menu. So it seems like nandroids do not actually affect VOLTE. Sometimes there may be a strange flash, bad activation, etc. Overall it works very well, and continued to work after flashing the mod pack, playing with settings, restoring user apps, etc. If anything, it almost seems like luck that the activation "sticks". I had it suggest restarting multiple times before the first attempt ever worked on stock. Had it not worked the second time I planned to RUU, reactivate, and then reflash fluent.
[Verizon HTC One (M9)] eriknors:
OK here's my situation with VoLTE considering I have not seen anyone post anything similar. After getting S-off I looked around the vzw forums for a rom and saw all there was was stock rooted so I flashed it and enabled VoLte and it worked no problem. Then I flashed Lee droid and realized vzw wasn't supported so I went back to stock after doing FULL WIPE and VoLte wasn't working. Then decided to FULL WIPE again and flashed Viper and VoLte was working. Made a nandroid of viper. Tried out IC with a vzw support zip to get signal on the rom but VoLte wasn't working went back to viper with restore and now cannot get VoLte working anymore. So IDK what to do now and I'm really not sure how to fix it or what causes it
[Verizon HTC One (M9)] michaelbsheldon:
In my extensive experience with M7, M8, and M9 you will not lose VOLTE unless you do a "full wipe" with a custom recovery before installing a rom. Period. On M7 & M8, full wipe ruined fast GPS lock. On M9, it messes up VOLTE and fast GPS lock.

Do a nandroid of the rom you like right now. Then run one of dottat's RUU's to 100% total stock. Do a factory reset. Enable your VOLTE. It will work.

If not, call Verizon tech support and have them redo your 'profile'. Then turn on your VOLTE. Now that VOLTE works, flash newest TWRP. Flash new radios.

Do only a reset, NOT a full wipe of the phone as you restore your nandroid. It should have VOLTE now on your old favorite rom.
[Verizon HTC One (M9)] dottat:
Full wipe as in you manually selected and wiped partitions? That's the only thing those of us who lost it permanently on a phone have in common. If you manually wiped partitions and can't get it back using the prescribed methods it's likely gone forever.
[Verizon HTC One (M9)] eriknors:
Well here's the kicker under advanced Calling it shows HD voice being active and every so often when I make a call the advanced calling features wanna work it seems. I am yet to flash the RUU because I've never done it.
[Verizon HTC One (M9)] dottat:
If it works intermittently it could be your local signal.
[Verizon HTC One (M9)] eriknors:
That's just it though it doesn't work at all but it acts like it wants to
[Verizon HTC One (M9)] eriknors:
I saw in the recovery thread we have the ability to reset the carrier partition just like we can cache or system. Do u think that might work? I mean I'm not really excited if I have to send my phone to Verizon. I'm gonna try one more thing tonight and see if it works if it does I'll report back if it doesn't then I guess I'm screwed
[Verizon HTC One (M9)] eriknors:
When you say lost it permanently do u mean there's no option in settings any more
[Verizon HTC One (M9)] dottat:
No the option appears. Although it's greyed out and it never works. No HD call quality. No data while on a 4g call. No vzw video calling.
[Verizon HTC One (M9)] eriknors:
How far back did u RUU? Cause I only did newest one. Someone told me I should go back to 5.0.1 and work my way up. I can actually toggle advanced calling on and off but nothing changes
[Verizon HTC One (M9)] dottat:
When I had mine go bad we were on the second ota. I ruu'd back and let it ota. If you have removed it from your account via the vzw website and ruu'd and factory reset and gone though activation of advanced calling from the m9 itself with no joy you won't be getting it back.
[Verizon HTC One (M9)] eriknors:
That's what I haven't done I switched out my SIM card to my M8 then unsubscribe from the HD voice on my plan then stuck my SIM card back in my M9 and rebooted the phone but it didn't allow me to reactivate the HD voice it was just already activated so I'm wondering if there's some sort of glitch

---------- Post added at 06:17 PM ---------- Previous post was at 06:16 PM ----------

The last night I switch my SIM card to my M8 and I deactivated HD voice on my plan because it doesn't work with the M8 then I switched this morning I switch my SIM card back into my M9 turned it off and turned it back on reactivated HD voice on my account but it never asked me to reactivate on my phone it was already activated
[Verizon HTC One (M9)] dottat:
You have to factory reset the m9 to reset activation after removing it from your account.
[Verizon HTC One (M9)] eriknors:
Okay so if you don't mind could you list the exact things I need to do in order so I can do it right that way I know for sure if I need to get my phone replaced or not please appreciate it

---------- Post added at 06:22 PM ---------- Previous post was at 06:20 PM ----------

Cuz I factory reset but it still shows as activated like it won't allow me to reactivate it on my phone
[Verizon HTC One (M9)] dottat:
Remove hd calling from account.. Flash RUU... factory reset.... activate hd/advanced calling from the m9 and reboot . If it doesn't function after this, it's not going to.
[Verizon HTC One (M9)] eriknors:
Okay thank you and would I be able to get my phone replaced like you did because when I spoke to tier 2 support they were stumped they didn't know why it's not working but they didn't offer to replace the phone they told me to go into a store which I'd rather not do
[Verizon HTC One (M9)] dottat:
I went through quite a few layers of troubleshooting beyond what a normal user would. In the end, I had to adamantly ask for a device swap which they finally did since they couldn't make my phone work.
[Verizon HTC One (M9)] eriknors:
Okay I understand I've had to do that in the past with other phones they're reluctant but they will give in thanks again crossing my fingers hope this works

---------- Post added at 07:11 PM ---------- Previous post was at 06:27 PM ----------

Well no dice I guess now I have to look into getting a replacement phone or deal with having poor call quality and no internet while on a call. Reminds me of the good old Droid Incredible 2 days. What a bummer
[Verizon HTC One (M9)] eriknors:
Has anyone bothered to compare the default.xml from the system/customize/ACC folder of a phone that has confirmed working HD voice and one that doesn't? Aside from that I called HTC yesterday and explained how Verizon couldn't help me any further with this issue so they recommended me to download HTC sync and connect my phone to it and choose "repair/update" [MENTION=3472611]dottat[/MENTION] is this something u tried doing?
[Verizon HTC One (M9)] dottat:
Wasting your time. That folder is replaced by the ruu. No different. What do you think HTC sync actually flashes ? ?
[Verizon HTC One (M9)] eriknors:
Well there's gotta be something missing from my phone compared to urs let's say if u have HD voice working and I dont. I am not saying u haven't thought of this urself I'm simply saying there has to be something that's missing

---------- Post added at 11:24 PM ---------- Previous post was at 11:20 PM ----------

Maybe part of some code only when there's a phone call being made IDK I can't read logs but I'm willing to bet if I made a log of making a call and u made a log of making a call we would be able to narrow down what is going on wouldn't u agree?
[Verizon HTC One (M9)] dottat:
I beat my broken one to death. Had some help within Verizon to look at stuff. We simply could not replace the info the phone lost. The ruu literally re-writes the system partition (and many others). The only two common items we figured out with others who lost volte was manual wiping of partitions and/or doing some digging around on the root of phone using a root explorer. It's possible even accessing a file in those folders with a root explorer prevents the system from passing key info related do volte to partitions that hold it and once broken it never can be restored.
[Verizon HTC One (M9)] eriknors:
Wow so it's kind of the way it was programmed to begin with plus people doing things we are not supposed to
[Verizon HTC One (M9)] dottat:
Pretty much. We are mucking up something that was supposed to be burned in.

Do you remember anymore details about what all you might have been doing? I know I wiped manually and was digging in a couple io files digging around for FM radio stuff
[Verizon HTC One (M9)] eriknors:
See that's what doesn't make any sense cause I had wiped manually then installed viper and it was working. Then I backed it up and only did a wipe in aroma when I flashed leedroid rom prior to it having Verizon support then restored my viper backup and ever since then it didn't work

---------- Post added at 09:01 PM ---------- Previous post was at 08:59 PM ----------

I know ur dead set on a manual wipe being the culprit but it's something else
[Verizon HTC One (M9)] dottat:
The poking around the root of the phone using a root explorer was the other thing.
[Verizon HTC One (M9)] eriknors:
What do u mean by poking around cause I didn't do much poking around
[Verizon HTC One (M9)] dottat:
Browsing around files in / on the phone.
[Verizon HTC One (M9)] aer0zer0:
thats crazy, i have done all sorts of crazy things in / as well as flashed different firmwares and flashed all sorts of roms. It just amazes me the VOLTE can be so fickle
[Verizon HTC One (M9)] dottat:
Yep...about 8 phones I've tracked so far. My replacement never had an issue.
[Verizon HTC One (M9)] eriknors:
[MENTION=3472611]dottat[/MENTION] do u think data encryption might play some sort of role like how it's affecting the HTC10 data connection when superSU is installed could that play a role in our volte?
[Verizon HTC One (M9)] dottat:
The m9 was not force encrypted. I never encrypted my M9. The two are unrelated.
[Verizon HTC One (M9)] dottat:
OK. Curious if you still have this phone. If you do, can you boot to boot loader and do

Remove volte from account.

Then ruu and factory reset

fastboot erase modem_st1

fastboot erase modem_st2

Then reboot and try volte activation.
[Verizon HTC One (M9)] eriknors:
The 2 commands

Fastboot erase modem_st1

Fastboot erase modem_st2

Is that what I would type in on my command window of my computer after I install the ruu?
