[HTC U11  Questions & Answers] LibertyMonger:
I haven't seen anyone complain of weak signal issues or signal issues due to coverage areas. My personal experience has been the best, much better than my HTC 10 but don't take my word for it. If you decide to try it there is a 30 day trial , it starts on the day you receive the device. You can return it if you have issues. I would suggest having a phone to fall back on just in case but I have been flashing ROM's, kernels and other mods without issues after removing the sim card when doing so. If you do experience the loss of signal after a reboot like some of us have the ruu.exe fixes it every time as a last resort. I still have not heard of anyone having that issue on complete stock.
[HTC U11  Questions & Answers] Anon2016:
Well consider me to be the first to confirm that I lost all non emergency connections to Verizon with a completely stock phone. Twice for no obvious reason and both times on the newest current software version. The second time before losing the connection I noticed that the phone felt warm at the top back, scrolling was rough and looked odd and text on the screen looked out of focus. So I rebooted and never got a signal after that. Verizon could not fix it. A factory restore fixed it the first time. The second time I just got a T-Mobile SIM which allowed me to instantly connect to their Network with no reset or anything and since I haven't seen anyone saying they have seen this problem outside of Verizon. It's good bye Verizon for me.
[HTC U11  Questions & Answers] secone00:
I also have to return this phone. Verizon was absolutely not what I would consider functional.

When the phone was first powered on I could send texts, use data, call, etc.

Updating the phone made me unable to receive or send texts or calls, yet I can use internet browsing with data fine. And even then, I can only connect if I go into the radio menu and specifically select either "LTE only" or CDMA/LTE. I've tried both with and without magisk, on stock ROM, on ViperU, after moving from 1.1x base to 1.2x base I can't do a thing with calls/texts.

Irrelevant to VZW, but the 3.5mm adapter came in broken and after updating the Adapter apk, the case was the same, no acknowledgement of plugging it in. Likewise for my computer and other phone... I plugged it into everything.

All of this I was still able to figure I could deal with and just patiently wait for a fix, but what broke the camel's back for me, the right side of the Usonic earbuds just moments ago became muted and muffled after one day of listening. This purchase was a mess all around. The only saving grace is HTC must be aware of all of this, they said they'd refund the purchase immediately.
[HTC U11  Questions & Answers] LibertyMonger:
Sounds like your device had other issues besides Verizon.
[HTC U11  Questions & Answers] Anon2016:
Maybe. Just providing what I noticed in case someone smarter than I can figure out a root cause. Im no expert on cellular tech, but those symptoms are very similar to things I've seen other electronics do when they have a memory overflow bug.
[HTC U11  Questions & Answers] LibertyMonger:
Yeah I been hoping more verizon people would report their experiences. I know these last couple posted are nothing like I experienced. My issue 3 times was a straight slash line through my signal bars. No other issues. And they only occurred after a reboot from flashing something. I stopped having that issue after removing the sim while flashing although I know that might not have anything to do with it. If I had any other issues like losing network while the phone is booted I wouldn't recommend it but my experience got much better its been very solid. Wish we had s-off to see if flashing the radio file would be a fix. Based on my experience I would recommend trying the phone only if you have a backup phone but based on my experience I feel most will have the great experience I had. It is most definitely worth a 30 day trial. My experience was nothing like some of these horror stories, I figured out how to fix my issues.

I read that some other users not on Verizon were having an issue with losing signal after flashing Magisk, I had that issue once out of three. Not sure how accurate it is cause you get jumped on when talking about it in certain ROM threads. I thought Verizon users were only having this problem. It would be nice to know more.
[HTC U11  Questions & Answers] CXTKRS1:
Phone was working fine with calls, text, and data since I got my U11..until tonight. The HTC Sense app kept bugging me to allow permissions so I finally did just that. After that the phone became stuck while using Instagram and after a restart it no longer connects to the Verizon network at all. Calls, texts, and data are all dead. It will occasionally connect at one bar and then quickly go back to limited service. I will contact HTC tomorrow but odds are it is going back. Once you add in this connectivity issue and the light bleed this phone does not come across as a flagship device.
[HTC U11  Questions & Answers] ieatabiscuit:
I managed to get the no signal issue on my phone, only thing I had on it previously was magisk, and never had an issue. I had flashed the Bad Boyz magisk, and it did it for me, but I think it was because it was flashed with the sim in. I did the RUU.exe mentioned by [MENTION=3795321]LibertyMonger[/MENTION], and restored my phone with success. I am now just finishing flashing Venom U 1.6.0, after putting my SIM back in I can confirm signal. It would seem that removing the SIM while flashing, and reinstalling it after the initial setup works. [MENTION=3795321]LibertyMonger[/MENTION] is quite likely on to something, and this is all on Verizon. I would suggest as a result of being able to duplicate his work so completely, that when installing mods, follow the same process. I say this because the way I had made the Bad Boyz Magisk ROM fail was by installing the Magisk V4A module. The ROM its self worked, but it was the Magisk version, so it, like the ViperOne Magisk ROM (or mini ROM really since they are both in the 90-150 mb range, and not a full ROM) didn't act up on me. Now, knowing I have a way back, I don't mind tinkering to help someone possibly solve some craziness!

---------- Post added at 12:53 AM ---------- Previous post was at 12:49 AM ----------

I still don't see what the light bleed issue is, mine doesn't do that, aside from the issue of no signal (slash bar through the signal bars) when flashing things, this phone's been perfect for me. I had contacted HTC about it a while back before I replaced my phone (the exe RUU didn't exist at the time for me to try it), and they were completely useless with troubleshooting it. Try that RUU exe (make sure debugging is on in dev settings), it seems to do the trick.
[HTC U11  Questions & Answers] CXTKRS1:
Forgive my stupidity on the subject but what is this "RUU.exe"? From searching it seems like you are flashing the phone?
[HTC U11  Questions & Answers] LibertyMonger:
I will post it for you buddy when I get up. You plug your phone into a pc an run the RUU from your pc. It's the HTC update utility, you can find it on the htc dev website as well. It fixes it every time.
[HTC U11  Questions & Answers] ieatabiscuit:
Alas, this morning after rebooting I got the connection drop with the signal slash icon. The RUU.exe DID pull through for me once again though. I think this time may have been due to the ROM being flashed was based on a dev release that was different than the phone's firmware release. As for the location of this mysterious RUU.exe, I found it by looking on either the BadBoyz or Viper U ROM thread under firmware. It will take you to a Google spreadsheet with DL links on it. If you're on a US Unlocked phone, you will want the .exe firmware version by Cpt. Throwback.

HTC U11 RUU/Firmware/Recovery/OTA Collection

---------- Post added at 07:51 AM ---------- Previous post was at 07:49 AM ----------

Did you pull your sim out while flashing? And was this after just a reboot or did you flash something and reboot? I would just like to know more about this issue.
[HTC U11  Questions & Answers] ieatabiscuit:
I have decided to make it a habit to pull the SIM like you have been, and given that it seems to work, I haven't tried NOT pulling it while flashing. I didn't have any issues all last night after flashing, and only noticed them when I had installed the host file for AdAway. I restarted, had no signal, then restarted again, and signal was back. Later this morning, I installed V4A, still had signal, then after restarting to get Nova to show Google Now, I had no signal, and could not get it back. The RUU.exe fixed it, and I am testing ViperU 1.5.0 now to see if maybe it was because the firmware base that 1.6.0 uses is different than the firmware I have (and because they have reports of troubles with messaging on Verizon with the 1.6.0, which could be part of the signal thing). I JUST got the 1.5.0 flash complete, so I'll let you know later today how things are going, after it's had time to decide if it'll play nice or not.
[HTC U11  Questions & Answers] LibertyMonger:
Ahhh yeah that's it... I had the same exact problem with adaway so I never tried it again, I use Block it. Adaway was the culprit. I think we have to pull the sim before anything like that. Any changes to system, modules or whatever.
[HTC U11  Questions & Answers] ieatabiscuit:
I thought that too, BUT, I pulled the SIM (I still don't see why that makes any difference like it seems to), and I've not seen any issues so far. It definitely seems to be immediately after installing things to the base system, and only after reboot for me. My best guess is that the system doesn't like to register now things and the sim at the same time? It doesn't make sense, but if it works...
[HTC U11  Questions & Answers] LibertyMonger:
I never tried adaway again after that, it would be nice to try it again with the sim card out to see if it works. I may try when I get my replacement.

---------- Post added at 03:05 PM ---------- Previous post was at 02:57 PM ----------

That's why it seems odd it has happened to complete stock. It seems those last few issues posted are completely different issues than me and you have had.
[HTC U11  Questions & Answers] ieatabiscuit:
The most recent things are definitely different, and I haven't seen anyone else with those issues. I think/hope that it's just that 1-off thing that sometimes just happens with electronics.
[HTC U11  Questions & Answers] LibertyMonger:
It seems I know enough from my experience to keep my U11 working solid. I would just wait to flash anything or install anything that requires a reboot until you are prepared with time just in case it happens.
[HTC U11  Questions & Answers] CXTKRS1:
Awesome, thank you for the links. I'm calling HTC for a replacement due to the light bleed issue and hopefully my next phone from them will be a bit more reliable too. If not then I will have the Essential and the V30 as options for replacing the U11.
[HTC U11  Questions & Answers] LibertyMonger:
Finding out my text messages haven't been working on my HTC 10, can't receive texts. It's been like this since I sent my U11 back and switched to my HTC 10. I been visiting my momma in the hospital every night so haven't really paid much attention, one day I had a load of them come through at once but I just thought it was cause of bad signal in the hospital. Must be a sim card issue from switching, I don't know. Gonna clean flash Viper tonight see if that fixes it.
[HTC U11  Questions & Answers] LibertyMonger:
So I tried putting my sim into my M8 to see if I get texts and they are still not working. So it is an issue with Verizon, not my phone. Unless my sim card is screwed up. I bet it has something to do with Verizon and how they got a screwey "bring your own device" program.

---------- Post added at 11:43 PM ---------- Previous post was at 11:23 PM ----------

By the way, I sent my U11 back on Saturday, they received it on Monday and they issued my refund today. So now they say I will see it back on my card in 5-7 business days. Not too bad.
[HTC U11  Questions & Answers] ieatabiscuit:
My U11 is still kicking with Venom U11 1.5.0 on it. Not a hiccup yet. Thanks again [MENTION=3795321]LibertyMonger[/MENTION] for the heads up to the RUU.exe. I wish it had existed BEFORE I had done a warranty swap since the first U11 I had wasn't broken after all.
[HTC U11  Questions & Answers] LibertyMonger:
Glad to see someone else enjoying it as much as me. So much negativity lol.
[HTC U11  Questions & Answers] LibertyMonger:
Just finished re-ordering the 128gb U11. Can't wait to see how much better 6gb RAM is.
[HTC U11  Questions & Answers] tml478:
I received my 6gb unit last week and I'm using it on Verizon. The thing flies. It was fast to begin with but there is a noticeable speed increase. Where I see it the most is when you go back to an app in your recents it always picks up where you left off as opposed to restarting the app. I'm on viper 16 full rom. I lost service one time randomly on a reboot. I hope sooner or later this gets figured out but it's not a deal-breaker for me. I just don't flash anything unless I'm home. I'm going to try tonight to do that SIM card pull before I flash to see if that helps.
[HTC U11  Questions & Answers] LibertyMonger:
Good to hear, yeah I see it being completely reliable as long as we only flash when we have time at home. So did you have the 4gb at first?
[HTC U11  Questions & Answers] tml478:
Yes I went from the 4 to 6 gb
[HTC U11  Questions & Answers] Wingedlion13:
I missed something in this thread. Why did you sent your U11 back?
[HTC U11  Questions & Answers] LibertyMonger:
Cause I wanted the 6GB and then a hairline scratch appeared from out of no where and that made my decision. I've never had to buy a device paying full price so I figured if I'm gonna have to fork out that kind of dough I want it to be the best. Now I get another 30 days to test it. Hoping it works out as good as my last two weeks with my first one and hoping Verizon steps up and fixes their mess. I'm gonna keep messaging them and push for a fix. I think it's only fair to send it back and reorder considering there is stability issues.
[HTC U11  Questions & Answers] Wingedlion13:
Oh OK, makes sense.
[HTC U11  Questions & Answers] CXTKRS1:
I have until early September to return the phone and if this band 4 issue is not resolved by then they're getting it back. On top of minor QC issues I will not pay flagship money for a phone that drops LTE coverage while my V10 is still holding the connection just fine.
[HTC U11  Questions & Answers] LibertyMonger:
If it it's dropping LTE coverage you better just send it back. Band 13 is LTE.
[HTC U11  Questions & Answers] CXTKRS1:
Is it possible that Band 13 coverage is spotty in that location? My V10 can use all 3 Verizon bands and I was not running any sort of application to tell which band it was on.
[HTC U11  Questions & Answers] LibertyMonger:
I never had this issue so I don't know. But if I was losing signal just from normal use while booted I would not keep mine.
[HTC U11  Questions & Answers] PieceKeepr:
I'm curious if you have tried upgrading to the newest Venom ROM? They were on 1.6.0 when I got my U11 and that is what I flashed first. I'm on 1.7.0 now but I have not been able to receive any mms messages since flashing ViperU. I'm going to RUU and then try 1.5.0 tonight based on some of the discussion here about base versions and see what happens.
[HTC U11  Questions & Answers] LibertyMonger:
Got my new HTC U11 6gb/128gb Beast. Getting ready to flash Viper now and set everything up before inserting my sim card.
[HTC U11  Questions & Answers] Zanzibar:
Flashing ViperU on my Sprint U11 prior to activating it caused the Hotspot to never work (or even show up in Settings). Same thing happened with another tester. We both had to return our phones, and activate the replacement prior to installing ViperU.

YMMV, but just a word of caution.
[HTC U11  Questions & Answers] ieatabiscuit:
I have not. I'm holding out until firmware updates, and they hammer out the MMS issue. It's a known problem on 1.6.0 and I'm not positive of 1.7.0. As it stands now though, 1.5.0 has been solid for me. I even used Android Pay just this afternoon.

I am jealous, but instead of an even shinier super shiny phone, I got a project car to tinker on. I'd say that's what even trade right?

---------- Post added at 10:48 PM ---------- Previous post was at 10:45 PM ----------

What he does is activated it, gets it all set up, pills the SIM, flashes, then reactivates it. That way it's already a familiar on the network. It shouldn't matter, but for some reason, on Verizon, it doesn't always play nice. This method so far has not failed though. No idea why, or why not either.
[HTC U11  Questions & Answers] LibertyMonger:
I got everything flashed, setup and working except for mms it appears. Was not aware of this issue as I'm a little behind on the threads. That sucks lol. I'm on Viper 1.7 I actually didn't activate it before flashing Viper but it seems to be ok for now.

***edited mms is working
[HTC U11  Questions & Answers] PieceKeepr:
I ran the RUU, set it up, and then clean flashed ViperU 1.5.0 and still no mms for me. I tried the HTC app and Verizon Messages.

So you went from stock to 1.5.0 and everything worked?

Yeah, I've been struggling with it since I got the phone. Some folks are saying that mms works for them on Verizon with the 1.7.0 update, but not for me. It's frustrating.

I haven't tried the pulling the sim card trick because I had never heard it before and was going to try it this weekend, but it appears that it didn't make a difference for you.

I thought it might be APN related because I found some settings on various sites that varied from what the rom has, but trying them did not fix the issue either.

I thought about getting a new sim card because I've had this one since shortly after the M8 came out, but I would think that if the sim card was bad then I'd have problems with the stock rom as well. Maybe not, I don't know.
[HTC U11  Questions & Answers] LibertyMonger:
Actually I just checked again, but this time I turned off wifi and mms is working. So I don't think I have any issues. When I sent mms on wifi before, it would receive but only show "downloading" but it appears to be fine.
[HTC U11  Questions & Answers] PieceKeepr:
Interesting, but now I'm not sure what else to try.
[HTC U11  Questions & Answers] LibertyMonger:
You can try getting a new sim. When I switched back from my U11 to my HTC 10, My texts were not working except sending. I could send texts but could not receive them. I got a new sim and it was fine.
[HTC U11  Questions & Answers] ieatabiscuit:
I've noticed that MMS on Verizon is screwy at best. Between a stock one m8, a modded one m8 (not the same phone, one was my wife's), a stock sgs6, a stock sgs8, and whatever phone my sister is now days, rarely does MMS work. I have managed to get my modded u11 to send pictures, they have yet to successfully send me any. I have begun to think it may not be the phone's fault.
[HTC U11  Questions & Answers] LibertyMonger:
Yes I agree, my last issue with text messages was with all messaging apps, it was a Verizon issue. But for now my mms is working on messages ÷
[HTC U11  Questions & Answers] secone00:
I'm hoping that I'll get some positive results today finally.

Instead of returning it I'm rather satisfied with the device overall and would rather go through effort with Verizon to get calls and texts working, then just buy a new 3.5mm adapter, rather than have those issues make me decide to return it. On my Verizon account I have the HD voice "app" purchased and enabled in my account/line, as a preface to the rest of this.

My first conversation with support went well enough, after a couple hours of talking and them trying to understand the problem, I was told they knew what was wrong and a new sim card was ordered and sent, I was told it'd be all good.

SIM card comes in just a day later, I hope for the best but of course, I immediately see something odd in the receipt that makes me think the worst, under the "FEATURES" section of it was a line that stated along with other features my account has, "DECLINE HD VOICE". Naturally I'm wondering what the hell they're talking about since my account clearly desires it enabled.

Back to the support rep chat game it was. The first told me he had no idea and said only HTC support would be able to help. Next rep made me hopeful and guaranteed he saw the issue, apparently they confused my HTC with my family member's much older model, he ensured that he would send out a new SIM card that would have it resolved. Here goes.
[HTC U11  Questions & Answers] ieatabiscuit:
Shouldn't be a SIM issue of that nature, but it's common for you to get internet, but no calls and no text upon first activation it seems. What I've found happens is that the SIM needs to be activated, THEN installed into the U11. What's happening is that the SIM isn't activating completely because it's trying to activate on a phone that's not a native Verizon phone. Also, a detail I later found out after several hours over the span of a week troubleshooting this issue is that there's the HD Voice activation for your specific phone line (if you have more than one like I did), and for the account. I had the line enabled, but the account not. It's literally some buried option switch that they toggle on their end. A trick to help activate your SIM, though, would be to put it into another phone to get it active, then swap it into the U11. Just to make sure the SIM its self is fully activated. It's tedious, because of Verizon's stone-age networking technology, but after a little poking, it starts to work, and then you're good to go. The good thing is that (for me at least) Verizon's done a lot to improve their customer service. I can say I feel they at least tried when I had issues, and they are getting better about it as they get experience with this phone. It's a bit of a unicorn to them, the guy in the physical store looked at mine like it was some alien artifact lol.
[HTC U11  Questions & Answers] secone00:
I bet you anything that's exactly what it is. I have been activating the sim separately on my old Samsung Note 3 before putting it in the u11 per reading this thread, but still was not seeing any successful results. However, I only have the HD Voice option enabled on my LINE, I did not realize there was a "separate" option for the account. That's got to be where the confusion is occurring. Thanks for your help! It's definitely been confusing enough still that I get about 5 different answers to the same question depending on which support rep I talk to, lol. I can tell they're getting there though.
[HTC U11  Questions & Answers] LibertyMonger:
Good luck buddy, we're rooting for you. If you get this issue worked out I think you will enjoy the Verizon HTC U11. I really don't think it's as awful as it looks from the negative experiences.
[HTC U11  Questions & Answers] LibertyMonger:
I don't have those kinds of network issues. My Speedtest scores are always at least 15mbps and I never drop signal or have any issues live streaming. Granted it may not be as fast but if everything works uninterrupted then that's good enough for me. If I was having those kinds of issues I wouldn't keep this phone.
[HTC U11  Questions & Answers] QD2DC:
And I'm sure the network speeds will vary depending on where you live, that's to be expected. But suddenly losing all signal and having to scramble and RUU or swap sims to get it back isn't ok. I'm not getting rid of my u11, and if this gets fixed one day it'll be my daily again most likely.
[HTC U11  Questions & Answers] LibertyMonger:
This has not happened to most of us. My network signal has bee absolutely STRONG!
