Weird issue with Wifi/LTE to 3G disconnecting - Verizon HTC One (M8)

Hi I currently have the latest Viper installed and I cant tell exactly what causes this issue or if there is a fix but it seems when my phone switches from 3G to LTE or vise versa, the data connection will completely drop and when I go into the settings under Mobile Data it will show disconnected. When I try and toggle the Mobile Data off and on (trying to fix it) it will not allow me and seems glitched. The only work around I've found is to go and change the Preferred network to LTE Mode, which connects but then I have no voice or text messaging. So then I will turn Mobile Data off, switch back to Global Mode, and then all is well in the world until it happens again and LTE switches to 3G.
I wont lie, this has happened on every Rom I have used since trying to update to 4.4.3, LiquidSmooth, Viper, and RKDN which is my current and I cannot for the life of me figure it out? I have tried EVERYTHING trying to remedy this issue from flashing tigers 4.4.3 firmware (http://forum.xda-developers.com/showthread.php?t=2723159) to even flashing back to complete 4.4.2 RUU putting me back to complete STOCK kitkat 1.55.605.2 located here (http://forum.xda-developers.com/showthread.php?t=2727831) and from there accepting the OTA updates to put me to stock 4.4.3 and then reflash TWRP and install new Rom and issue still remains!? I feel I am at the unfortunate point where this may be a defect with one of the radios or something in the phone and know matter what I do, its not going to fix... SO I may need to flash stock RUU and return to VZW and get new device? Which would suck, as I am not sure if there is a root/bootloader unlock method for a brand new M8 4.4.3, Is there? Anyone out there experiencing this?

This sounds very similar to my issue which I created a post not too long ago:
http://forum.xda-developers.com/verizon-htc-one-m8/help/network-issues-t2901138
I haven't tried flashing another ROM yet but I was thinking about it.
Also I tried popping out my SIM Card to see if there was anything wrong with it but it looks fine.

Were you able to change the mode to Global and everything work until the radios switched from LTE to 3G or vise versa? Good to know I am not the only one

I'm not completely sure yet. I just know with the LTE/ Legacy 3GPP mode, I'm basically stuck in LTE. When would normally lose LTE and switch to 3g, It still shows 4G with 1 bar but not be able to do anything. Also phone calls don't work for me in that mode.

Awesome, glad that worked...Thats what I am dealing with. Just hoping that I maintain a LTE connection so my phone does not disconnect where I cant receive calls or text until it's too late.

Well, I guess Im just going to have to take it into Verizon and see if I can get a swap. Must be defect at this point

Does toggling Airplane mode off and on fix the issue? I sometimes get a loss of connection (I've never checked to see if Mobile Data says it was connected or not), and Airplane mode fixes it for me.
Also, the new devices can be S-Off'd, but there's a $25 fee. It's worth it if you get a new device though IMO.

Thanks for that tidbit about the 25 dollar s-off. Forgot about that. SO yeah I will probably take in and get a swap. Thanks

Nexus 5 CANT connect to 3G Network

A month or so ago I started to get only EDGE signal from my carrier wherever I went , every time, I've been over a month trying every solution and nothing has worked, here's details of my findings and what I've done.
1) I tried to go back to stock firmware, didn't work.
2)I tried flashing different radios from the XDA thread, nothing.
3) I called my carrier and did some tests, checked the APNs and the phone network config, everything was ok and still not working.
4) I tried my girlfriends SIM(from the same carrier) and same result, no H signal anywhere.
5) I opneded the freaking phones back to check the MIMO antenna and it seems alright.
6) I went to another carriers shop and tried their SIM, and boom it worked with H just fine.
I'm very curious on what the probke. May be, I should point out that my carrier uses the 1900mhz band for HSPA, while the other carrier uses the 900mhz band for HSPA, so, somehow the phone isn't able to connect to the 1900 band, but it does connect to the 900 band with no issues, how in hell is this possible? It worked just fine for 3 months until now...
I am overseas so I cannot ask for a replacement from Google, also I don't wanna sell the phone to get another one, and I don't wanna have to switch carriers , I've been with this one for years and I have a great plan and I have tons of services tied to this number, I do t wanna go thru the hassle of changing everything.
So, any recommendations, any technical help? Ideas? Please let me know I really think this is a software issue and I wanna get it fixed!

Clearly two things are possible,
1- You messed up by flashing different radio bands, lesslikely.
2- The 1900 band in your phone antenna is damaged, you better do a replacement, i am sure in this one.

But u didn't test ur SIM-card on another Nexus5
If ur sim on another n5 works fine so ur sim-card is ok
but ur phone with another sim-card also works fine
so this is between ur sim-card and ur phone
a compatibility or any damage on sim-card and ... caused these issues
This is not because of ur phone
ur phone hardware and software are fine ur must check operator & etc.
maybe ur operator is not compatible 100% for n5 or KK 4.4.2 !

downgrade to 4.4 !!!
best way;
unlock > root > custom recovery > multiRom > then install any ROM u like, for example stock 4.4
or 4.4 based release of CM

As I said, my connection was working fine for weeks with 4.4.2 , hence it is not the cause of the problem, switching it to 4.4 won't make any difference

This might sound silly, but you made sure you're not forcing 2G/edge mode, right? Have you tried forcing 3g (WCDMA only) mode from this menu?

Switched from Nexus 4 to Nexus 5 have the same problem.
I found myself having a very similar problem after flashing CM12 on my nexus 5 (D821). I flashed the 20 jan Nightly and everything was working fine untill i update to the 22nd jan nightly when my 3g simply stopped connecting or had very spotty signal, i didn't give it much thought at first thinking it was a nightly problem but after one week i reflashed stock ics, locked the bootloader, event tried kit-kat and the problem is still there. Before flashing cm 12 2g/3g/lte switching was working perfectly for about one year.
So utill now: i flashed different stock rom's, different kernels, radios, custom roms and nothing worked. When i tried switching the sim with another one from the same network, 3g worked on the other phone so i doubt that the sim is defective, but on my nexus i had the same connectivity issues. I also played with the *#*#4636#*#* menu and managed to get 4G working again but only in CDMA mode and I cannot receive any calls or texts, but the internet connection is working, 3G also connected at some point but the signal was very poor.
I am lost now, and also desperate because edge is too slow for anything, what confuses me though is that this seems to be a software issue since the cause was me flashing a different ROM but all the signs point to a hardware issue.
Can anyone plese give me a second opinion? Is there any fix for this? (Also i recently went to my network's service to replace my screen assembly, could also this be an issue? the issue appeared about 2 days after getting it back from them, also about the same time i flashed cm12)
Thank you for your time.

Modem Issues?

I've had my Nexus 5 for about 2 months and noticed several major modem issues with it.
The first is wifi randomly just not working. It will supposedly remain connected but I wont be able to load anything at all. I can turn wifi on and off and still nothing. I have to actually shut down the phone to get it to function again.
Other times when the WIFI will work fine. If I ever switch it off and go to my cell signal it will not go on to data or lag to go on to data or go on to 3g data when I'm in a zone with LTE coverage. Often I have to restart the phone to get it to pick up data or LTE as that is faster than actually waiting it to switch. Sometimes It just doesn't switch.
4.4.2
M8974A-1.0.25.0.23.zip
Not sure where you live but modem 17 did wonders for me. 23 which is what your on now , which is what I had installed on my device when I received it was not good for me. See my post here http://forum.xda-developers.com/showthread.php?p=52907605 To see which modem is 17 and if you wanna give it a shot then do so. That's my suggestion. Make sure you read the entire original post and backup your previous modem first just in case something goes wrong in the flash which more than likely won't but if so you can then just restore previous modem.

Verizon 4G Handoff Fix

I was asked to also post this fix that I came up with in the general forum from the CleanROM thead, as it should help people having the same issue. The issue isn't actually related to that ROM but a broader M8 issue that I was unaware of and thought was specific to the ROM. It's been confirmed with multiple users having the issue that the fix below does indeed fix the random data issues that require a reboot/airplane mode toggle to resolve.
A fix for the 4G --> 3G, WiFi --> 4G, WiFi --> 3G, and 1X/3G --> 4G handoff issues that some people may be having is outlined below...
In a nutshell, we just need to change EVDO Rev A to "Enabled" instead of the 3rd "eHRPD" option in EPST.
Dial ##778 --> Edit Mode --> 000000 --> Modem Settings --> Rev A --> Enable --> Upper Right Corner Menu --> Commit Changes
Might cause a reset data connection with the transition due to a possible new IP or hamper simultaneous voice and data over 3G (which is possible), but it will allow the phone to establish a data connection on its own again and not get stuck on eHRPD 's random buggyness. Should transition back to 4G eventually as well
eHRPD basically for allows switching between LTE and EVDO systems seamlessly (no reset data connection from 4G --> 3G and back, slightly faster speeds, same IP, depends on tower...)
Changing this setting basically tells the modem in your phone to act more like a 3G phone when requesting 3G data access. Bypasses the hybrid-ness and just forces you on the legacy EVDO Rev A. network.
If the phone signal (4G is weak) at the time of the eHRPD transition, it can mess up. This change tells it to not bother with that and when the 4G signal isn't available just revert completely to 3G to register and not wait up for transition info. Makes it more cut and dry, and to be honest it does not really impact things. When the phone detects a 4G solid signal again it will switch back on all its own.
Same issue happened on the HTC Thunderbolt when Verizon was messing with things during initial 4G deployment. Only recent changes are the whole VoLTE ramp up, and that could be the cause of this recent crazyness.
To revert this change:
Dial ##778 --> Edit Mode --> 000000 --> Modem Settings --> Rev A --> eHRPD --> Upper Right Corner Menu --> Commit Changes
Thank you for sharing this! Very good find and positive feedback has been showing in response. Worth a try for everyone having these symptoms.

Isn't Android Revolution HD is in the Generic HTC One M8 section?
Sadly, this only works with VZW based ROMs. Anything with parts taken from other bases, or a GPE ROM it may not work and the code for EPST might be different/EPST might not work and/or the option may not be there.
That code doesn't do anything on the Viper rom

Sounds like you guys need to flash CleanROM...
After making a Nandroid back up of your current system then do the edit and restore Nandroid if you want :angel:
But to answer the OP, yes. GSM ROMS will not have this option unless the Dev adds it in. Otherwise its a CDMA only function (I believe).

It works on my viperone 1.8, are you on the newer versions that you do not have the new verizon firmware for yet ?
This is great, I come from an HTC One S but also switched between that and a Galaxy Nexus so I could tell a difference in the way my signal acted and we have had signal issues with the HTC One S for quite some time now and it all seemed to stem from when we finally obtained s-off, seemed our One S was never the same, may have been placebo but I was worried it was happening all over again with our blessed M8 lol. The One S was not Verizon and may not be the same issue. I just tried this and it already seems better.Thanks very much. They still have not found a fix for the HTC One S

If you go back to 1.8 then it will probably work for you, 1.8 was the last verizon that worked correctly for your verizon firmware. I was on the 2.3 but had too many wifi issues so I went back to 1.8, which is less wifi issues now with this fix I seem to not have any wifi issues so far so think its working for me. I"am not going to update viperone until the new verizon firmware is out in a zip to flash in recovery, because the wifi issues are not worth it to update now.
Any more successful difference's people have since doing this?
I was listening to a radio show streaming app today on Wi-Fi and the app kept stopping. every 10 minutes or so after trying this fix. It was the first time I listened to this app with this phone but listen to this app all the time with my other phones and never have this issue. It was consistently dropping Wi-Fi and 4g wasn't picking it up. I am running CleanRom with Harmon Kardon. I tried disabling Harmon Kardon to see if that may have been the issue since I am not accustomed to using it yet and it seemed to work better without it but still dropping signal. The signal icons seemed uneffected. I guess I am going to remove Harmon Kardon see if that makes a difference before I revert back from this fix.
I did this and my phone now reverts back to LTE and doesn't get stuck on 3G like it had been doing since day 1. I was getting tired of cycling into and out of airplane mode. Thanks for this advice/fix!
Is this the bug I experience where I have 4G signal, but am "offline"?
If so, that has been driving me nuts. I am on the stock ROM, S-OFF Rooted. Is this present with the off the shelf version?
Reporting back after 3 separate complete wipe/reflash/restores on my M8. Here is my status as of now:
Tuesday: Tried flashing stock recovery and did factory reset. (didn't fix the handoff issue)
Wednesday: Tried flashing RUU then returning back to CleanRom 1.4 (didn't fix the handoff issue)
Thursday: tried the EHRPD fix listed below. So far today NO handoff issues! I don't want to jump the gun, but this appears to have done the trick. I have gone from 1x to 3G to 4G with no issues so far.

If anyone is using the Verizon M8 with a GSM sim and can't access the USSD code ##778# then go into settings -> mobile data -> preferred network -> LTE/CDMA and try running the code again in the dialer. Dont forget to change the preferred network back to Global after applying the fix by the OP.
This has worked great for me. Thanks for posting. Was incredibly frustrating to have to fight with the phone every morning on my way to work to get it to connect to 4g. I had to toggle airplane mode, switch preferred networks and even reboot or some times do all of the above - lol. Thanks again.
Apparently this is a known issue and per Verizon, they're working with HTC to fix it. But I've also read that the problem could be cause by running xposed modules which seemed to be the case with me. I'm s-off running stock and was fine until I installed xposed.

This fix does not impact Wi-Fi directly, just eHRPD for mobile data transitions. Sounds like the app is the problem. Have the same ROM with Harmon Larson installed - no issues.

Yup. Seems to be impacting certain phones regardless of ROM. I'd give it a shot and see if it helps. If not just change it back.
Big thanks to the OP. I've been dealing with the the eHRPD limbo since I got my phone in April. I live in a low 4g area and was experiencing text and mms problems big time. It was always happening when it was bouncing for 3g and 4g. When I would check the network details it would say eHRPD. I would constantly toggle airplane mode off and on and change network preferences to get it to work. Really annoying. Well I tried this last night and the signal is staying in 4g almost all the time and I have experienced no problems with messaging. I am running Viper 1.8 and had to kind of guess to find the edit button after entering the numbers in the dialer, for some reason the Edit button did not show up but it was there when tapped on it. After that it was easy. Thanks again for the help. I wish Verizon was as good.

OTA update killed all data connections

I am on T-Mobile since April and everything has been fine except the known LTE handoff issue, I just keep the phone in UMTS always.
The night of Oct 28th I received an OTA (not a system update) and I guess it changed radio settings or updated the firmware. Ever since, NOTHING I do will get the phone to pick up ANY data signal on T-Mobile. Did Verizon decide to block the Maxx from use on other networks???
On wifi everything is fine, but I get no GSM data, no Edge, no 3G, no HSPA and no LTE. I can't receive any media text messages either.
Can anyone tell me what the hell happened?

Phone is non-Dev edition (as far as I know), I'd be happy to even put another ROM on this thing if possible, I know there is a MotoX ROM that also fixes the LTE issue on the Maxx.
I use this as my primary/business phone so it's really unconvenient to have no data while im out and about during the day!
Please help!

Try a factory reset, and reset your APN to default, and re-enter the settings. As I stated in the other thread you posted in, update is working great for me, and Verizon can't lock the Maxx/Ultra/M to their network as part of the FCC's Block C agreement.

Ok, I did the factory data reset and and it's still the same.
One strange thing I noticed is that it will say 3G or 4GLTE in the status bar right next to the signal strength, but it's grayed out, and only present when wifi is turned on. As soon as I turn wifi off, the 3G or 4G logo disappears instantly.
It did this both before and after the reset. regardless, when I'm not on wifi I have ZERO access to data networks.
Phone worked great on tuesday, and now it's pretty much useless after Verizon update. How can I roll back to the previous firmware ?
you could try replacing the radio from previous version.

Could you point me to a walk-through for this and is it possible on a stock non-developer edition?

I am on T-Mobile since April and everything has been fine except the known LTE handoff issue, I just keep the phone in UMTS always.
The night of Oct 28th I received an OTA (not a system update) and I guess it changed radio settings or updated the firmware. Ever since, NOTHING I do will get the phone to pick up ANY data signal on T-Mobile. Did Verizon decide to block the Maxx from use on other networks???
On wifi everything is fine, but I get no GSM data, no Edge, no 3G, no HSPA and no LTE. I can't receive any media text messages either.
Can anyone tell me what the hell happened?
100% stock Droid MAXX, on 4.4.4
23.3.24.obake-maxx.verizon.en.US
MSM8960PRO_BP_23255.127.76.00R
3.4.42-gd47915e-00002-g37bce85 [email protected] #1
Phone is non-Dev edition (as far as I know), I'd be happy to even put another ROM on this thing if possible, I know there is a MotoX ROM that also fixes the LTE issue on the Maxx.
I use this as my primary/business phone so it's really unconvenient to have no data while im out and about during the day!
Please help!

I have a droid maxx on t mobile and i have had no problem using H+ instead of LTE for txting and data here in chicago...
but last night i accepted the XLTE (1FF-obake_verizon-user-4.4.4-SU5-23-release-keys.xml.zip) OTA and quickly realized that t mobile data no longer worked. I tried to revert back using RSD lite but that failed due to downgrade protection...i was thinking i would have to just flash a 4.4.4 gummyrom over stock and move on but then i remembered i had an old twrp backup of 1FF-obake_verizon-user-4.4.4-SU4.21-release-keys.xml.zip from earlier in september
you must have an unlocked bootloader and twrp installed to restore the backup but the restore was successful and bypassed the downgrade protection...gsm carrier data was once again working...
i will post a link to my twrp backup once it finishes uploading...and if anyone else has a 1FF-obake_verizon-user-4.4.4-SU4.21 stock twrp backup they could share that would also be a huge help
ps.youre only chance to unlock your bootloader is sunshine or stumproot or another on of jcases masterpieces if it wasnt already patched by this last XLTE update

Go inside the Droid Ultra Original Android Development and look for thread with [Radio] in the title. The latest that comes with VoLTE update was posted by CrazyRussianXDA (this is the one inside your phone now), previous versions were by Topsnake. Create a folder called fastboot and extract the files there. You must download the fastboot tool here - http://forum.xda-developers.com/showthread.php?t=2317790, install it into the same fastboot folder. Just follow the simple steps and yes it is possible to do it on stock non-developer version. Just for precaution, do not copy and paste the command, type them in.
So I haven't changed a thing on the phone. This morning I re-entered the SAME APN info yet again with no luck.
Today around noon, while driving my phone suddenly starts getting emails and now seems to be working fine. Even the LTE handoff issue on T-Mobile seems to be gone.
I have no clue. . . but it works now!
I GREATLY appreciate everyone's help on this matter! Maybe an issue to watch out for in coming weeks ?

seandean41...Are you saying that your phone is not having any issues with T-mobile now? Like it fixed the LTE handoff issue?

Yea I have it set to automatically select network now and it's sitting on my desk in LTE mode, yet I can pick up the phone and make a call no problem.
It used to always drop the first call and then if you redialed while it was in HSPA it would make the call.
Texting working fine too.
T-mobile had told me that they were having some data issues in my area, so I wonder if being halfway across the county today at lunch did something. The original problem was definitely something with the phone because if wifi was turned off, it wouldn't even display a G, E, 3G, or 4G logo. And with wifi on, the logo was grayed out and totally nonfunctional.
but maybe talking to another tower did something with the radio. . . . . . no idea really. Shooting in the dark here!

I just applied the upgrade. Ultra on T-Mobile. I have no data anymore. I can't even pull up a web page. I am able to call and text no problem. The strange thing is at the beginning of October I moved from Verizon to T-Mobile. Verizon sent me the Android upgrade. Hopefully this will resolve itself over time. I've tried rebooting the phone a couple of times and messing with the mobile settings...but nothing. Phone info app shows me it's registered to T-Mobile and the Signal Strength is around -110dBm. It shows me GSM Service as "In service" and the GPRS Service as "Connecting", Network type LTE, GSM disconnects:==========DATA========
(UPDATE) I called t-mobile support and they were excellent. Short and to the point they stepped me through adding the APN info, and data is now working again. Prior to the upgrade it was working without any APN info. The old problems I was having with SMS messages not being sent, and having to redial 2 or 3 times to place a call are gone. My Verizon Droid Ultra is now working perfectly on T-mobile. Just ran a speedtest on 2-3 bars with 4GLTE and I got 13Mbs down and 8Mbs up
i just picked up a maxx and EVERYTHING works. lte is crazy fast as well. latest update too...
su5 tmobile data

Verizon Signal Issues - Help

I need some help here, weird Verizon signal issue. So I got my U11 on Thursday the 22nd of June. I tested out the stock rom, all working fine, signal working fine too. Then I unlocked the bootloader, put twrp on in system RO mode, put magisk on, then put viperU 1.0.0 on. Viper/magisk and everything was working perfectly, I still had signal, could make and receive calls, send and get texts, wifi was all good, everything was good until Friday afternoon. I think it had to do with me trying to install the ota 1.1.0 viperU, but my signal dropped, still had 4g but that was touch n go. I tried to reinstall the ota because as far as my settings said and knew, I was still on 1.0.0 and when it checked for updates it found 1.1.0 again. After that 4g would work for a moment at boot then die, and there was no signal for calls/texts, that has the signal bars full with a slash through them. I tried fresh installing viperU 1.0.0, no change. I tried every combo in the test/advanced settings, changing the preferred network mode and ims settings, turn the radio off and back on and it would see verizon and try to connect, sometimes seemingly getting signal and changing the signal bars and getting 4g, then losing both. The status msgs on the advanced settings page would go back and forth as far as registered on the network, so I went to verizon and tried to get a new sim, the new sim didn't change anything, BUT a weird thing that happened is when the vzw rep went to the back to get me a new sim and activate it my U11 got signal, both 4g and call/text and I even got a msg, then it died again a moment later. So next I tried completely restoring and relocked my bootloader and installed the 1.11.617.4 RUU for my OCNWHL using htc_fastboot which it did perfectly fine, but still no signal. The bootloader says relocked(L) and software status: modified. Shouldn't it say official again since I flashed the RUU? I have tried reseating the sim and rebooting multiple times too. Oh and one more thing I noticed, my WiFi is touch and go now too, it'll say connected but websites fail to load, apps fail to download, etc until I turn off and back on my phone WiFi. Any ideas guys/gals on how to get my phone connected again? I just want to be able to use my new U11! Thanks in advanced!

All I can say is a lot of people are having problems with Verizon, me being one of them. I've had the phone almost 2 weeks and still can't get it working. I've talked to HTC and Verizon so many times and they say it's being worked on.
same here. Spent a couple days with near constant contact with Verizon trying to figure out out. Got in touch with HTC and it seems it may be a firmware issue. I can verify with no doubt that it's not the sim though. I've put mine back in my old phone, it worked. I put my daughters in my new phone, it failed to work. I even got a new sim for mine, but no luck. Multiple ROMs, multiple RUUs, and multiple factory resets, and wipes. All we can do is waiter, and pester the hell out of HTC to get them to hurry up.

It's so stupid that they don't even do testing before putting it on the market.
If either Verizon or HTC would come up with a simple software update to enable CDMA and all LTE bands, that would solve everything. The problem seems to be that Neither is putting much priority on it.
BTW: Since the U11 works with Sprint, it has the CDMA and LTE bands built in. They're just not set up to fully work with Verizon yet.
Exact same problem.
My unit is going back for refund tomorrow. 4 hours of work trying to get it going and I'm done. HTC blames VZW, VZW says it's hardware. $650.00 paperweight. No thank you.
I'll reorder if this get straightened out. There are hundreds working just fine on VZW.
Seems to be just a few of these that wont stay connected.

I was starting to lean towards firmware today because of the wifi going in and out. Seems like to get an app to download from play I have to search it, start the download, turn off wifi, turn it back on and then it'll download, yet updates download just fine. Fandango app won't load movies or anything. Etc. So I'm wondering if it's the system or radio...
stock U11 no issues on VZW
I took my sim out of my VZW line to test it out on my U11. I did some speed tests before I took it out. I inserted the VZW sim into the U11 and it booted up with no issues. Received LTE and ran speed tests and they were similar to the other device. There was VoLTE available and it was stable but I didn't make any calls with it. So just sharing my experience with my stock, Unlocked U11. I put the Tmo sim back in but it's good to know it'll work. It seems like some are having issues from the get go and some are having issues after modifying?

That's what's so screwy about it. On mine, I get WiFi flawlessly, and I even get mobile data, in 4g even. I just can't talk, or text. Before that, I could text, but no data, and couldn't talk. It's got to do with the way it's using the radios being screwy. The hardware functions, I've had full connection before, it lasted about 2 hours, and sounded amazing even.

Short answer: Yes. I noticed mine stopped after installing a ROM on it, but it was not the first one (test driving to see which I liked on it best). Others have the issue even with it locked still. I think the ROM flashing was more a circumstance than the cause in cases like mine. I even RUU'd back to stock, did factory resets, and tried other SIMs. It also seems to be only Verizon, unless someone on another network wants to set me straight.

I remember an issue on Verizon and the M9 that after flashing a custom rom, you stood the chance of loosing VoLTE. It did not happen to everyone and did not happen all of the time. I flashed custom rom for months and then one day, boom, VoLTE gone. The only way to get it back was to get the phone replaced. RUU did not work to get it back. Sounds similar to what is going on now. So my question is has this problem affected anyone that has not unlocked the bootloader yet?
I just checked the M9 Verizon section and looks like they did find a fix without replacing the phone. But I think you need to be s-off. Interested if this could resolve any of these issues here.

I will be trying this later today. Good ol' @dottat
If we get s-off we can probably safely flash roms without magisk n still have volte n even a more stable radio/system firmware, if dev's make it happen of course. Or am I wrong, I don't mind having magisk, I just want to be able to root n customize my phone with it still working as a phone n not a fancy calculator or wifi only device haha. I'm debating getting a replacement from HTC until the firmware stabilizes at least, then I'll mod some more. Cause mine was working perfectly fine until I tried to put viperu 1.1.0 Ota on it.
I just noticed that when I drag down and get the quick settings into view there's a note in the top left that says "the sim card is missing or not readable. Insert a sim card" and that doesn't go away even when the occasional notification that says "sim card inserted click here to finish setup" pops up.
Was fine for a couple days - now suddenly today only getting "roaming" service. Manually trying to connect to VZW fails and says my SIM isn't allowed access.

The full story is in the op of this thread, but it started about a day after I got the phone, started with only voice/text going out, then lte dropped too so now my phone is wifi only. R u on stock or have u unlocked ur bootloader?

Ah sorry, didnt notice you were OP. I have unlocked but was running stock OS with Magisk (no other mods, I just wanted root). Noticed that turning of VoLTE in phone settings killed connection, so I was able to toggle that off and on (+airplane mode in between) to usually resurrect connection. Now nothing is working. Going to do a full wipe now to see if it comes back.

No worries haha. My signal today is intermittent, I'll get bars but can't call because when I try 4g turns off. In the HTC test settings, when I have bars it sees Verizon network but not my phone number, where as when I don't have bars (bars with slash through them) it sees my number but not Verizon network. For u to see this menu type *#*#4636#*#* in the dialer. My VoLTE is activated in settings tho.
Factory wipe didn't help either. Doing RUU now. This is so ridiculous. Also I accidentally deleted my backup, oops. Le sigh. This thing will probably be going back. Sad. I was loving the phone.

Bruh - go in menu -> Phone Info -> Turn Off Radio
Select "LTE Only" Select "WCDMA/LTE"
Turn radio back on.
Fixed problem instantly!!! Thank you SO SO MUCH!
edit: MMS doesn't work, but SMS seems possibly ok? not sure.
edit 2: WCDMA/LTE is the magical answer. All seems working now.
