Stuck with 3g only - Verizon HTC 10 Questions & Answers

Last week I flashed the .23 firmware along with Santod's stock .23 ROM. Flash seemed to go ok, I did a full wipe prior and just set up the phone from scratch. Right away, I started having voice calling issues, both incoming and outgoing. Some incoming calls, though not all, wouldn't ring and I'd get notified of voicemail. For outgoing calls, about half the time the call would drop during the Dialing phase. For both incoming and outgoing calls, those that actually went through, quality was such that both sides couldn't be understood. A quick call back, and sometimes the quality was ok. (if the call actually went through) During this time, I also noticed that the phone was dropping to 1x during the call, and I no longer had working HD Calling to other Verizon customers. I thought it might be the tower I was connecting to, like maybe VoLTE was down, but the issue was present across town.
I tried redownloading (checked hash) and reflashing both firmware and ROM, same issue. I tried using the .23 RUU, same. I tried using the .20 RUU, same. While on .20, I took the OTA back to .23, same. I even did the RUU back to the last Marshallow ROM. When I did that, I'm having the same issue, except now I'm stuck on 3g instead of 4g. (still drops to 1x for calls, drops, poor quality) When that didn't work, I took OTA's back up to .23, but it's still stuck on 3G. Network Settings says LTE/CDMA.
Can anyone point me in the right direction to solve this?

I believe the only way you will get 4g back is to wipe the modems. This happened to me too.
From the white bootloader screen run the following two commands in adb
fastboot erase modemst1
fastboot erase modemst2
Hope this helps.

This got the phone out of 3g. It still drops to 1x for phone calls, though. I haven't had a chance to test call quality or see any drops yet.
Thank you very much!

G1 missing calls recently...very weird

I'm running CyanogenMod-4.0.4 on a rooted G1 on the Orange Switzerland network. Usually, everything is great...I love this phone and the CM stuff is awesome. But I've recently been having some trouble with calls not reaching my phone.
I noticed the problem for the first time yesterday, but can't be sure it hasn't been going on for a while now. If someone tries to call me, the call either gets sent straight to voicemail, or sometimes, it just keeps trying to connect and finally fails. Then again, some of the calls get through just fine. The phone itself had good 3G reception throughout the observed problems, and SMS and data traffic was working perfectly. Calls from my phone to others also worked all the time.
If I reboot the phone, the next call goes through without trouble, and I've also not had an established call losing connection so far.
Is anyone else observing similar trouble? Or do you think the problem sounds more like something on my providers end?
EDIT: Just something else I just remembered, no idea if it might be related: I also noticed an abnormally high battery drain today. Usually, once the phone is fully charged, the battery will last for a bit more than two days before it starts complaining. Today, about six hours after removing it from the charger, it was showing 20% charge. I recharged it from there, and it's been holding normally since then.
Not sure about the phone calls issue, but for battery life, have a look at Settings->About Phone->Battery Usage and see if anything is abnormally high.

Looks about normal to me.
Cell standby : 42%
Phone idle: 39 %
Voice calls: 10%
Display: 5%
And a bunch of small stuff.
Same problem today, have seen this on my stock G1, was the reason I did the rooting and went to JF, and now to Cyanogen.
I already re-installed Radio and HSPL, still same. Probably need today to wipe and reinstall ROM ?!
I'll keep you posted.

Do you have the Overclock Widget running on your computer ???
In the process of screwing around, I uninstalled the Overclock Widget, but also reinstalled ROM and Radio. Now everything seems to work again. So for the moment I guess the overclocker was the root cause. Will do some more testing.

Still having problems... Get voicemail if I call my phone. After reboot, phones answers again. Probably will wipe and reinstall tomorrow.

Same problem here.
I am having the same issues also. No appearant pattern to it though. Sometimes it works, sometimes it doesnt. My girlfriend has called me four times in a row, some of the times, it went straight to voice mail, othertimes it will ring (on her end) then go to voicemail. My phone doesn't even show missed calls. Text messages work fine.

yeah i this happened to me yesterday. my phone would only ring 1 ring and then it would say missed call. since there are a bunch of people it seems like it could be a network issue and not the phone/rom.
I tried all kinds of stuff, but yesterday I figured out the following:
3G enabled and also connected to network via UMTS : Call goes to voicemail and I get a connection error dialing out.
Now switch settings to: Use only 2G. Effect: All calls (incoming and outgoing) perfect.
Very wired. So i guess it is a network problem. Can you guys try this as well?
I'm having similar issues.
Whenever I'm in an area that has HSDPA (3.5G) coverage, and my phone is constantly using data, the caller won't get connected (won't ring on his end nor on my end, and caller won't be forwarded to voicemail). I also have issues calling people, I would have to try calling the person like 5 or 6 times to actually make a call, I would simply not get connected, not even a ring.
If I'm in an area with normal 3G coverage (384kbps max DL speed), even if I'm using data, call WILL come through and I can make calls without problems.
On 2G, with constant data usage, phone calls would get forwarded to my voicemail automatically, so no unreported missed calls.
I'm not sure if this issue is specific to my network, but I tried calling my operator's customer support and they asked me to take my phone to its authorized dealer. I've been running cyanogens ROMs for a long time, and I'm still having those issues.
I know someone who has the hero running on the same network I'm using and is reporting similar problems.
I have seen it do this on stock, JF, the dudes, cyanogen, and now Dwang ROMS!
I have youmail setup to email me with missed calls, and every 10 or so calls will go straight to voice mail or I'll get a missed call on youmail, but not my phone never registers it....
I had called Tmobile Customer service like 6 months ago, even before there was a youmail App, (they didn't know what youmail was).....told me it was a youmail problem....
I am pretty sure its not a youmail problem, but I have no idea what in the heck it is..
Its happened once or twice (that Im aware of). Running the modded stock from here.
Also my notorious problem with MMS.
Not sure what it is. My real curiosity is if this happens on Moto Cliq and Droid. Really curious if these weirdo issues are HTC...G1...or android based.
A similar issue has been reported to google, please star this so it gets some attention by android developers. Missing calls and not get notified about them is a big issue for me.

I have a tmobile sidekick lx and it is doing the same thing. Does anyone know anything about that at all?

[Q] No service, out of coverage, radio issue.

I'm in Estonia. Phone is N4 16GB stock 4.2.2, no mods/no root.
Have an issue with gsm radio.
When phone is active, then i have signal, I am able to call out and receive calls, BTW, calls don't drop. When left untouched for approx 10minutes it is cut from carrier. It does show the coverage bars, but when called in, then states as out of coverage. When trying to place call it hangs in dialing display. When trying to end the stuck call, it hangs on ending call display. Have tried different SIMs from different carriers, the problem remains. Only cure so far is to reboot, then i get next 10 minutes of service. Have restored to factory settings couple of times, tried without applying Google account. No luck. F***!
What to do? Has anyone faced similar issue?
Rolled baseband M9615A-CEFWMAZM-2.0.1700.48 back to M9615A-CEFWMAZM-2.0.1700.27, got longer usage time, radio still freezes
I get weird data loss too with 48, never calls though. I too prefer 27 as a result and that just works for me.
With 27 however your autofocus wont work anymore (camera) but since I don't use it that much guess that's not a biggie (touch to focus still works however).

Cellular network (calls and sms) not working

Phone is rooted and unlocked with multirom since July and has been working great. 3 roms installed; liquidsmooth 5.1.1, chroma 5.1.1, and Ubuntu.
Yesterday, calling started to be intermittent. Sometimes switching airplane mode on/off fixed it, sometimes it didn't. Today I cannot get calls to work at all. Phone shows dialing but then hangs up before any ringing. Incoming calls don't work either, it goes straight to voicemail. I thought it may have been lollipop but the problem occurs in Ubuntu as well. Funny thing is that the phone finds the network carrier and has decent signal.
I havent changed anything on the phone recently, only thing is that I dropped it 3 days ago. Thankfully no cosmetic damage, but am starting to think internal damage.
I've tried soft reboot, cold booting, pulling the sim...no luck
Should also mention I'm on virgin mobile canada...
Any ideas?

You could try flashing the radio image via fastboot.
I tried flashing the radio via recovery... No luck either

No calling, only SMS/data/wifi working on any ROM and/or stock

I've been using AICP for a while (Marshmallow), but haven't done an update in a while. By a while, I mean that I don't think I've flashed anything in weeks. Suddenly, I cannot make or receive calls today. Yesterday I made a number of calls just fine. I checked all the standard possible causes, dialer apps, default apps for phone, etc. After no success, I decided to flash back to stock.
Now I'm on stock 6.0. Same problem, cannot make calls. All I get is a screen which says "dialing" until it makes a tone sound and hangs up, never rings anyone. My phone never rings or responds when other people call. I do have full bars and service, and my APN is set up properly with AT&T in the USA. SMS and Data work fine, and so does WiFi. No other problems at all with the phone. I've had it for about a year and a half with no real hardware issues other than a loose charging port. No drops, no cracked screen or anything.
I'm wondering if anybody has a clue about what the problem with my phone is. I'm willing to generate and provide logs if there's a way to do that which could show the issue.
EDIT1: Derp, just tried the SIM in my girlfriend's phone. Seems to by my sim card. I'll go to AT&T tomorrow and report back here if the issue is fixed.

Sometimes not able to receive calls

SM-G900T - currently running stock MM ROM
Family Mobile (T-Mobile MVNO)
I've had the S5 almost four years now. Worked great on stock ROM, Cyanogen, and for a year or so on Lineage. For the past year, I've had cell network issues.
I started having a problem running Lineage, where I would randomly not be able to receive calls or SMS. In testing, I discovered that this would last for hours or days, until I rebooted the phone. Then it would work perfectly for a few hours and the problem returned. This was the same regardless of my location or cell tower, and who the call was from and what network they were on. I've never had a problem making calls or sending SMS, it's only been with incoming.
I've always been able to fix this by flashing back to the stock MM ROM. Then I would get tired of it and try Lineage again. Then I started having the same problem on stock, too.
I flashed stock a few times and finally got it working where I don't have the incoming calls problem, but there was a new problem. No LTE bandwidth. I started off with 7 mbs down and 100 kbs up. Now when I test it, it's 100 kbs for both. I've been running it this way for a few months.
Customer support from my carrier has always insisted that everything is fine on their end.
Now I'm afraid to flash anything, dreading the incoming calls issue will return.
Are there any diagnostic steps I can take to figure out what the problem is?
