[HTC U11  Questions & Answers] LibertyMonger:
I ran with having only band 13 for about a month and a half. It was completely 100% stable as long as it was booted, just the speeds were slow in most areas. I could not tell it was slow by using the device, everything worked great. Until I messed with things and rebooted and lost signal after booting. But with band 2 I've hit speeds close to 100mbps and the bands work normally.

I just tried to check bands on stock 1.16 but couldn't figure out how to do it without root. So then I tried to fastboot boot twrp to keep my stock recovery and flash root, but I made the mistake of flashing root without pulling my sim card first. So I lost my signal on reboot. I guess I will run the ruu again and try again. But I think what Beaups is trying to say is once we enable bands 2 & 4 with Network Signal Guru it is permanent. Which is completely fine with me cause seems to be the only fix for now.

---------- Post added at 09:14 PM ---------- Previous post was at 09:00 PM ----------

The very first time I try to flash something without pulling my sim card, I lose my signal. I haven't lost my signal in over a month by pulling sim before flashing. I am pretty convinced it works.
[HTC U11  Questions & Answers] beaups:
Pulling Sim before flashing stuff has nothing to do with losing your signal.
[HTC U11  Questions & Answers] LibertyMonger:
Yes I already knew people would say that but it has been 100% effective.

---------- Post added at 09:25 PM ---------- Previous post was at 09:24 PM ----------

So how does all other carriers not have this problem? The only way my phone knows I am on Verizon is with the SIM.
[HTC U11  Questions & Answers] beaups:
It's not effective. It's a coincidence. I suppose it's possible" that booting the device with no Sim decreases the chance of the signal loss issue, but flashing or really anything in twrp with or without Sim has no consequence on the signal issue.
[HTC U11  Questions & Answers] LibertyMonger:
How can I check bands without root?
[HTC U11  Questions & Answers] beaups:
Many apps can, including lte discovery.
[HTC U11  Questions & Answers] LibertyMonger:
Man I wouldn't doubt you, I know you are the genius of all this with much respect, I have high respect for you so I hope you don't think i am disrespecting you but I have had a lot of practice with this with 2 different U11's and I can guarantee to lose signal if I flash a few things with the SIM in and I can guarantee to not lose signal if I remove my SIM. It has been 100% effective, I think there may be 2 different signal issues, I don't have the one that some claim to have with just getting connected. I think that is the issue some have who claim to lose signal without being rooted. I don't know for sure i am just going by my experience. Others have had great luck with removing the SIM as well.
[HTC U11  Questions & Answers] beaups:
No disrespect taken, but its a placebo/coincidence. Just like everyone thought the new version of TWRP solved the issue, until it didn't. Because it has nothing to do with TWRP. Not to mention TWRP doesn't even init any RIL/SIM in the first place.

People have this issue whether locked or unlocked, stock, rooted, etc. It's a bug, plain and simple. And the fact that the bug doesn't exist on other carriers really doesn't mean anything. This is the first phone (at least that I'm aware of, definitely the first HTC) using cdma-less Verizon, it likely didn't undergo the same Verizon testing a Verizon-branded device would undergo, and it has bugs. Verizon's setup, especially on this device, is very unique. And something is broken.
[HTC U11  Questions & Answers] LibertyMonger:
Thank you, I am monitoring LTE Discovery now but it isn't as active with showing band switching as Network Signal Guru. So far I have been stuck on Band 13 on the last 1.16 software, trying to see if my bands still work after a ruu before I update to 1.28. I usually can see my bands switching from 13 to 4 when I am at home but I am mostly on 13.

---------- Post added at 10:00 PM ---------- Previous post was at 09:54 PM ----------

All I can say is it works for me. Whether I am being fooled or not I don't know. I just know I have had a normal phone since doing this.

---------- Post added at 10:03 PM ---------- Previous post was at 10:00 PM ----------

Also some say ruu's never worked for them, that is another reason I am convinced they have a different bug cause ruu always regains my signal.

---------- Post added at 10:09 PM ---------- Previous post was at 10:03 PM ----------

I have just confirmed what Beaups said about Network Signal Guru, running an RUU to stock does not change the enabled bands 2 & 4. Once you run Network Signal Guru one time the bands are enabled permanently. I just switched back and forth from band 4 and 13 from complete stock no root.
[HTC U11  Questions & Answers] beaups:
It will work for you until it doesn't, because it's a coincidence.

This is not necessarily an indication of two bugs. Certain efs/nv pieces are cached, and those are reset/restored when doing RUU. Some pieces are not cached/restored. If it's a filesystem corruption issue, for example, that could cause RUU to solve for some and not others, depending on where the corruption occured. But there also could be 2 bugs. Or 3. Or 100 :)
[HTC U11  Questions & Answers] LibertyMonger:
Yes but a lot of people are having Verizon account issues, they can't even get their phones to work. I think this bug is not a software issue I think it is an account issue, that may be why ruu does not work. But I am just going by experience, you are going by super knowledge so I would believe you over me, but sometimes hands on is better Lmao.

---------- Post added at 10:24 PM ---------- Previous post was at 10:15 PM ----------

Also I have had the same exact experience with 2 devices, I started removing my SIM when flashing after about 2 weeks after my first 30 day trial, my last 2 weeks I never lost signal from flashing when removing SIM. And since then I am over my 30 days with my 2nd device and have not lost signal at all when pulling SIM when flashing. But after a month and a half of this kind of success, the very moment I forget to remove my SIM when flashing, I rebooted and signal was gone. Placebo maybe, but it is one hell of a coincidence. [MENTION=3483646]michaelbsheldon[/MENTION] haven't you had this same success? I don't want to sound like I am arguing. I am just discussing my experience. But now we are on to the next test, hopefully the new update fixes the signal loss, hopefully I won't have to think I need to remove my SIM anymore but if I lose signal again while flashing that is my only fix. As for the band issue, whoever does not want to root will just have to be stuck with band 13. But Network Signal Guru works and it works good.

---------- Post added at 11:21 PM ---------- Previous post was at 10:24 PM ----------

I kinda already knew Verizon wasn't going to enable bands 2 & 4. I was emailing Verizons top executives and that Jesus dude flat out told me they were not going to enable them, or however that works. I know people jumped on me when I was trying to point out the messed up relationship between HTC and Verizon but something is up. We know bands 2 & 4 work so there is no other explanation.
[HTC U11  Questions & Answers] christiebunny:
I hope so too! I'll know when I get home later tonight, hopefully!

---------- Post added at 08:37 PM ---------- Previous post was at 08:30 PM ----------

two new bugs for every one solved, if it's anything like my old programming days :(
[HTC U11  Questions & Answers] LibertyMonger:
One more thing, I was able to restore signal with a stock, unrooted nandroid but was never able to restore signal with a custom ROM that had signal and others had this experience. So rooting or custom software seemed to effect the signal loss issue. If I lost signal, I could make a nandroid of the current ROM, flash the nandroid of the stock unrooted ROM to get signal back, then restore the custom ROM backup that had no signal but have signal back.
[HTC U11  Questions & Answers] PieceKeepr:
The last few pages have been very interesting and educational. I always thought a full wipe update or an RUU truly wiped EVERYTHING and left the phone in a state as if it just came out of the box brand new. Now that the RUU is out I was going to play around with it this weekend but now I see I'd just be wasting time. I'll stick with the no-wipe update I already flashed unless there is some benefit to the RUU that I'm missing.
[HTC U11  Questions & Answers] LibertyMonger:
Are you s-off? Or did you have to be s-off to flash the no wipe update? I purchased s-off yesterday just in case but I went the ruu route since I wanted to test the missing bands, to see if they were permanent after network signal guru
[HTC U11  Questions & Answers] PieceKeepr:
You have to be s-off. I bought it just for this update.
[HTC U11  Questions & Answers] LibertyMonger:
We are just phone users and flashers, we don't have the knowledge that you and the other dev's have here so when we say we activated, enabled, unlocked or triggered something, that's the best way I know how to describe it. I have no clue what technically happened. All I know is the bands didn't work and now they do. We don't have any Dev's who are even interested in this phone on Verizon, we are just making it work the best we know how from trial and error and for me it has worked. We can't even talk about our Verizon issues in other threads without being ostracized Lmao. I would like to see if we can get WiFi calling and Video calls to work, I guess it is not possible but we have no kind of development community for Verizon users like we did in the past. There used to always have to be a separate thread for Verizon users cause things that worked for unlocked devices did not work for Verizon devices. It is the way it has always been until the HTC 10. I know I was attacked before for trying to make this point but this is fact. Unlocked devices from HTC never worked for Verizon and Sprint.
[HTC U11  Questions & Answers] beaups:
Disagreeing != Attacking. And people disagree with your point about unlocked devices because you are wrong.

Unlocked pixel works on verizon

Axxom whatever it's called works on verizon

Several Nexus devices work on verizon.

Unlocked iPhones work in Verizon (and have for a few years)

Edit: I missed your "from htc" part. Almost accurate, except the unlocked pixel did work on verizon.

In the comments of this article, people are having the same issues we have been having. This article is from 2016. Verizon didn't allow unlocked devices until the Nexus 5X and these are the only ones up until this article, The Nexus 6, Nexus 5x, Nexus 6p, Moto X Pure, Moto G. And even in them, not all functions worked like visual voicemail. I know they have been nicer to Pixel and iPhone recently, but they have never been nice to HTC.
[HTC U11  Questions & Answers] sdamark:
Why? Why do you just want to argue with [MENTION=711482]beaups[/MENTION]? You do realize you're very lucky this expert on HTC devices and Android in general is even paying attention to "your" thread. Right?
[HTC U11  Questions & Answers] LibertyMonger:
I'm not arguing. I just tried to originally make the point that unlocked devices never worked well with HTC on Verizon. Why are you getting mad? I was just making comments and getting responses. It was just a discussion. People have been understandably mad and bashing HTC I was just making the point that this is how it has always been and people disagreed. I will stop, it's not a big deal. I can be ignored. And why the heck do you get smart and call it my thread? I will stop discussion for you.
[HTC U11  Questions & Answers] aer0zer0:
maybe [MENTION=711482]beaups[/MENTION] would be willing to educate us on exactly what we are missing, and if there is anything we can do to help our own causes here?
[HTC U11  Questions & Answers] sdamark:
Definitely not arguing, or mad. Just making an observation in a thread, "your thread", that I follow.

Have a good night, friend.

Peace and good luck to ya.
[HTC U11  Questions & Answers] LibertyMonger:
I have just been trying to help. There isn't much action in this thread for Verizon and I am having complete success with the U11 so I share my story in case it helps others. I am stuck on Verizon for now and so are others who want this device. No one else is reporting this kind of success so I think it needs to be discussed. I have been on Verizon since the HTC One M8 and have had all of them since. I always wanted an unlocked HTC but could not get one because of Verizon. We hoped it would be different this time and it is, but there were still issues and to me the main cause is cause Verizon has never allowed unlocked HTC devices on their network. There isn't too much to disagree with in my opinion, I never started an argument. I already apologized to beaups if he should happen to take it that way. It's really as simple as that.
[HTC U11  Questions & Answers] sdamark:
He had already stated he would look into it when he gets some time.

That's pretty good, for a guy who develops for a bunch of Android devices, to be willing to spend some of his time looking into the dropped signal problem on this.
[HTC U11  Questions & Answers] sdamark:
Well said, sir. Thank you.
[HTC U11  Questions & Answers] LibertyMonger:
Ok guy's, I'm not going to argue, I will just show these two things then I am done with this. You can have the thread. Notice in the pic for the unlocked version, it specifically says "No service" for Verizon. And then notice in this link what it takes to unlock a Verizon HTC One M8. And I will say again, Verizon sold the HTC 10, we just could not use HTC Dev to unlock it. And you could turn an unlocked model into a Verizon model. That's all I am going to say about it. If I am wrong, fine I don't care.
[HTC U11  Questions & Answers] LibertyMonger:
You guy's act like I blew this up when all I was doing was stating facts that I can prove. You could not just pop your Verizon SIM into an HTC unlocked HTC 10, you had to flash the Verizon firmware first. I bought my HTC 10 from Verizon which already had the Verizon firmware. As for the HTC devices before that, you had to buy the HTC directly from Verizon to get a working Verizon phone. Or you could buy a Verizon version from HTC but it was not unlocked. It was Verizon specific. As I said if I am wrong, so be it.
[HTC U11  Questions & Answers] christiebunny:
*bleah* no luck yet, even after the RUU. There's a couple things I haven't tried yet-- but if I can't get it working by monday, I'm going to start making some noise, and being very un-lady-like about it! I'm tired of waiting for a fix that doesn't seem to be coming. :(

There's no other phone even close to this, as far as I know, but unfortunately I can't kick verizon, and can't afford two plans, so barring [MENTION=711482]beaups[/MENTION] or HTC coming up with a miracle, my only choice seems to be 'yell and keep yelling' :/
[HTC U11  Questions & Answers] QD2DC:
I guess I still don't know what point you're trying to make. It's clearly known that unless it states that it works on Verizon, it won't work by normal means, if at all. That's common knowledge. Again you can't blame Verizon for that. And if you decide to buy unlocked and it might support Verizon that's your risk take, again you can't blame Verizon for that. I did with the axon 7 and it worked great. I did with the essential and same result. Both claimed Verizon support and both worked by simply popping my sim in. The point [MENTION=711482]beaups[/MENTION] is making and myself is that when unlocked phones claim to work on Verizon, it's the manufacturer stating so, NOT Verizon. This thread is about the U11 on Verizon, but the blame is clearly on htc and possibly caused by Verizon restrictions, but at that point maybe HTC should not have claimed compatibility....if Chinese company with a small mobile presence in the US like ZTE can make a phone fully compatible with Verizon without official Verizon support, there's no reason why HTC couldn't have.

---------- Post added at 08:54 AM ---------- Previous post was at 08:41 AM ----------

There's been so much overlooked here by random posts I completely missed what your exact issue is. Are you one of the unlucky ones that lost total signal seemingly at random when it was originally fully working?
[HTC U11  Questions & Answers] LibertyMonger:
You guys just missed my point. I made a true statement and that would have been the end of it but no one believed me and it blew out of proportion. My initial claim is that Verizon used to never let non Verizon phones on their network up until recently and they never allowed HTC developers edition or unlocked phones on their network. I specifically was talking about HTC and how this was HTC's first shot at it alone where Verizon allowed an unlocked HTC phone. And for some strange reason bands 2 and 4 are not allowed. We already know they work. But had you guys just believed me or remembered that Verizon has never just let unlocked HTC phones. That should have been the end of it cause it was just a true statement. So my point was Verizon has never been as nice to HTC as it is to Google or Motorola or iPhone. And iPhone doesn't count anyway cause you can't unlock the bootloader. My point also was Verizon does not like us to have unlocked bootloaders. That is why they never let us use HTC Dev. That's all.

---------- Post added at 01:42 PM ---------- Previous post was at 01:38 PM ----------

Have you already tried the replacement route? At this point you need to get it replaced. Your issues are very odd and not consistent with others issues.

---------- Post added at 09:04 AM ---------- Previous post was at 08:42 AM ----------

And as it appears, the ZTE is on Verizon as a prepaid device. So there is some cooperation and can you unlock the bootloader on the ZTE? https://www.verizonwireless.com/prepaid/smartphones/zte/
[HTC U11  Questions & Answers] LibertyMonger:
One more post and I am done for a while. We pretty much know where we stand now that the update has come and passed. Any other issues that remain have to be Verizon account related, like [MENTION=5027435]christiebunny[/MENTION]'s issue. Or she needs a replacement through warranty, just want to say that for as much as I flashed today and getting my Viper ROM all set up I would have normally rebooted with no signal by now, with the SIM card in. But it has not happened so I do believe at the least, that issue is fixed. The band issue can be fixed with root. Any other connection type issues have to be a Verizon account issue. That is my final thoughts.
[HTC U11  Questions & Answers] QD2DC:
Yea ZTE allows their bootloader to be unlocked as well. But that's not the the axon 7. The axon 7 was carrier unlocked as well but they don't list Verizon anymore as compatible but it's fully functional anyways. I'm guessing they didn't care to get Verizon certified so they can't claim it'll work, but it still does.

Yes it comes up with HTC U11 as it did before, but there's no signal initiated on the phone with the Sim in.

I don't understand why this issue has not been figured out yet. Did you update from the phone settings or run the RUU?

[HTC U11  Questions & Answers] aer0zer0:
Just throwing s*** here, have you tried using a GSM sim, then doing a factory reset with that sim in it, verifying signal, then throwing your Verizon sim in? Buddy of mine has the axon 7, and that's what he has to do to get Verizon radios going when he RUU's. He has dual Sim in the phone, so he has 1 of each anyways. Just a thought
[HTC U11  Questions & Answers] LibertyMonger:
So that proves even the Axxon 7 has the same issues with Verizon. Verizon is not friendly with unlocked devices.
[HTC U11  Questions & Answers] QD2DC:
Any idea if the Verizon employee had HD voice feature active on his line? That is a must for the U11. The s8 is capable but you still have to manually add HD voice to your line. You can sometimes call support and they'll do it for you but it's much easier to do it via the web portal. If you get an error you'll see it and that'll tell you right away the U11 wont work until that feature is active.

No it sounds like he has the dual sim version which is not the same as the US unlocked version. The US unlocked version has no issues on Verizon. Many unlocked phones have had little to no issues with Verizon as stated many times. It's just the U11.

Us unlocked is dual sim or single and SD. It works 100% though, it's tricky to get the radios going

I've been reading articles like this one on multiple devices and not all are always smooth sailing, it seems a lot of people have trouble getting the verizon radios to work on unlocked devices. In this article they talk about the same types of problems and fixes and even when they do work they don't get Verizon specific features like VoLTE, wifi calling and visual voicemail. There may be an exception with some newer devices but it's not all smooth sailing outside of HTC. I can find many more examples of the same issues.
