Network goes out randomly - Verizon HTC One (M8)

Hey guys I was gifted a (used) M8. It came with the lastest official CM12.1, everything unlocked. I have found that network will stop working randomly and switching airplane mode on and off will do the trick. Thing is, I have missed important calls because of this. I've already researched the subject and no one seems to have a solution. This post is my last attempt at fixing this issue. Only details I can give you is I am using a Verizon phone on MetroPCS, and I suppose that has something to do with it. Also, is there any (preferably free) way to get my phone to automatically switch airplane mode on and off every 15 minutes or so when the screen is off?Thanks in advance!

Have you tried using a stock ROM or changing radios? Is your firmware up to date?
Can't speak from experience from using a cm12 ROM, but generally stock usually works better with signal over AOSP, especially if you're in a poor signal area.

I used to have similar problems, turned out WCDMA and LTE bands that my carrier used were disabled.
For my case (T-Mobile), I simply activated WCDMA 2 & 4 and LTE 2 & 4 and now have signal almost 24/7.
You can do this with CDMA tool since your phone is Verizon branded.
As for automatically cycling Airplane Mode, I'd imagine Tasker can do that.

Dropped Connection to Network Problem

my phone will drop connection and then not reconnect. no voice, no data. (wifi still works)
what I've tried:
1. Different radios/firmware
2. different roms
3. different preferred network types
4. switching airplane mode on and off
what I haven't tried:
1. different sim
2. calling tmobile for suggestions
What else could cause this problem?
it could be a hardware issue
Hello,
I have the same issue than you !
I am facing issues such as call drop and no 3G data connection in some area in my region since I have 5 signal bar and H letter displayed (HSDPA connection)...
I have found a workaround consisting in:
1 - Switching to GSM Only mode (2G Only)
2 - Desabling Mobile Data Connection
Then it works, I can pass and receive voice call ...
Regards,
Nino
I'm new to the Sensation and having the exact same issue.
Followed the stickies in the Dev section to S-OFF, root and bypass SIM lock and then once the SIM card is inserted I get only GSM and no data.
If you use *#*#4636#*#* in the Dialer and go to Phone Information do you notice that it always switches to WCDMA preferred? I change to GSM/CDMA auto PRL like all my other Android devices (on Rogers Wireless) and it disconnects, reconnects but only for GSM and no data. It sometimes says it's connected to EDGE or HSPA but no icon at the top right and then it reverts back to GSM.
I have also tried flashing virtually every firmware, ensuring that the radio and RILs match (I had an HTC Desire Z so the HTC phones are not new to me entirely). I don't know what else to do. I tried a Bell SIM card and tried all of the same options to no avail.
I really hope someone can figure this out. I don't want to have destroyed a phone that I just bought for my wife. Her Atrix broke and I purchased that outright as well, so this is really killing my wallet. I've been through about 10 Android devices and I wouldn't say I'm a newb, but I really do feel like one right now. This sucks!
Get a new sim from tmo if it's over 2 phones old.

Exactly. Although I got it before I saw your post, you were completely correct.
definitely try a new sim card.

I've tried 5 different SIMs now. It's not a SIM issue. The other poster has a different issue but mine's identical to the OP's.

Disable LTE without custom ROM?

I have the ATT HOX and want to disable LTE due to the known issues with missed calls etc. Would it be possible to disable it through root access WITHOUT installing a custom ROM?
I'm not sure what AT&T do to their phones but can you not change it via Settings > Mobile Network > Network mode.

What known missed calls issue? What would LTE have to do with missed calls? LTE on AT&T is data only. It doesn't do anything with calls. You can dial *#*#4636#*#* and try to set it to gsm only or something.

Believe me I have tried. It's not possible. But ik you said you didn't want to, but you really should look into custom ROMs. There's some that are basically stock with just better battery
Except for ATT. Its a well documented fact that they have it disabled. Any changes you make revert back to default.

Its a fairly well known issue with ATT and LTE phones.
As far as I can tell since LTE IS data only it has a hard time receiving calls when its connected to the LTE network. I think it has something to do with only having 1 antenna and it cant communicate on voice and data at the same time. Or, maybe not.:silly: All I know is that when my phone is connected to LTE I will not receive phone calls. All calls will ring a few times and then go to voice mail. I eventually get voice message notifications when the phone switches out of LTE.
Any changes made in the field test mode do not stick. Thank you very much ATT.

I've had 3 different LTE phones on AT&T and never had issues with missed calls and I'm constantly on a LTE connection. My phone kicks to hspa+ right before I receive a call and then it rings. Goes back to LTE about 30 seconds after I hang up. The only thing I can think of is that you are on LTE only in the field test mode thing. That will definitely give you call problems. What does it say that you are connected to when you go into the phone information menu?

I've had a few LTE phones too but I can confirm that this is an issue with AT&T and the HOX. (At least in certain areas.) The phone is *supposed* to do what you said and switch off LTE when a call comes in but that doesn't always happen. I've noticed it the most at my office where I usually have 4 bars of "4G LTE" or one or two bars of "4G". I'll have a long period of time with no incoming calls or texts and then when I make a call (and the phone switches to "4G") I get the backlog of voicemails and text messages. Hard resets haven't helped and AT&T refuses to admit that it's a problem.
Heres a summary of what I have found:
1 Being in field test mode does not affect incoming calls.
2. When making outgoing phone calls with LTE or HSPA displayed in field test mode, the connection will switch to UMTS and then revert back to LTE or HSPA after hanging up. I dont know what that means, just throwing it out there.
3. On a few occasions during my testing I have noticed that I could not receive calls when HSPA is displayed in field test mode. I think that the phone had just switched from LTE, although I havent been able to 100% verify that.
4. My connection at my house varies between LTE, HSPA,EDGE.
5. EDGE is great. My phone makes and receives calls all day long when I have a EDGE connection.
6. Most of my testing has been at home where I have crappy reception to begin with. On a few occasions when I had my wife with me I had her call my phone(connected to LTE). Same as when at home, my pone never rings.

Exactly!
I have Samsung Galaxy S3 on AT&T and I have same issue when connected to LTE. I have been working with AT&T CSR for over a week and no resolution yet. I have talked them into switching my data plan from 300MB LTE to Unlimited Standard Phone data plan. (Unlimited standard phone data plan uses HSPA+ and not LTE, which would resolve the issue)
From what I have understood so far, its not the phone, its the AT&T LTE network.
Wouldnt people with the same phone have more answers for you?

No, because this issue is not related to the phone but its related to AT&T LTE network. So everyone on AT&T LTE network has same issue and not only people with HTC one X.

I was on phone with them last night. They have created a case number for me so their "technical team" can look into it. They promised me to get back to me before friday on this.
For changing the data plan, the CSR tried to change it but it didnt work yesterday. I blame it on the CSR because I know some people on XDA has done that before. I am gonna call them again and have a different CSR try it or me.
And plus, with this change, you get unlimited HSPA+ for just $10.

Thanks for the link. Those settings actually worked for me. I had already tried a couple different APN configs but none of them seemed to stick.
So, now I have successfully disabled LTE.
Unfortunately, I'm still having intermittent missed calls with the phone connected to HSPA. Also, At work in certain areas, we have rock solid LTE reception and guess what...no missed calls. WTFrack?
At home the only time I can get regular calls is when the phone is connected to EDGE.
I seriously think that there must some relationship between 4G/LTE and signal strength. Does anyone know If EDGE and 4G/LTE use the same towers or same power outputs?

LTE not working?! Manual Programming codez (updated)11-7

I got my Nexus 5 yesterday and finally got it working. I live right next to a LTE tower and I can't seem to get LTE.
1. Checked PRL
2 Checked Sim
3 Checked Profile
4. Called sprint
5. Checked network settings.
When i put the phone in airplane mode, and back off. It jumps to LTE for 2 seconds then 3g
Anyone having these issues ???
*manual re-fresh*
*#*#72786#*#*
after that, phone will reboot and "re-fresh network"
Also, my phone wen't into global mode, which you will need to change that back to LTE mode.
- Still isn't fixed ...
will report back ..
Manual Programming Code
*#*#675#*#*
edit: MDN = phone number
MSID: split
UPDATE
doing *#*#4636#*#* and selecting LTE only does indeed make LTE work both visually and functionally, with a loss of voice of course, but as soon as you go back to LTE/CDMA auto it'll require a reboot to take effect and LTE is once again not working.
(from sprint forums) - confirmed
I'm having these issues with Sprint as well. Thanks for your updates. I'll let you know if I learn anything.

Here is how I fixed it for myself on Sprint.
Settings > More > Mobile Networks > Network Mode
Change Network Mode from Global to LTE.
It will still connect to Evdo, ehrpd and Lte and switches between them as needed.
Luckily I haven't got hit with 1x since trying this out. My area has maybe one or two spots where I'd get 1x instead of ehrpd.
Settings hold after a reboot. I was driving to work today with my phone playing my music and it seemlessly switched between 3g and lte on it's own.

I guess so because I was having that same initial problem you were where LTE would connect for a few seconds then when I tried to do anything with data it stalled out and went to 3g.

Mine does that too.
BUT, nothing in the settings has been able to fix this.
How long since you activated? Mine would not connect to lte at all until last night... about 30 hours after activation.
Now it connects fine. I tried everything including flashing the modems posted in dev, swapping sims, trying every different network config and nothing worked except lte only mode which then kills 3g and voice.

I too am having the exact same problem as the OP. I can change the setting from Global to LTE and the phone will connect to LTE for a few seconds before switching back to 3g.
I am coming from the Note 3 on Sprint that got great LTE here at home, about 16mb down and 4mb up but I am hoping this gets resolved quick.
I'm on T-Mobile and it favors sticking on HSPA+ instead of LTE. If LTE gets down to one bar, the phone decides it's time to switch back. Compare this behavior to my Nexus 4 and it would stick on LTE come hell or high water. I would stay on LTE while in the office and this phone refuses to even get on LTE in the office. I don't get it.
Some have suggested this is a "power saving" feature, but I call BS on this because my Nexus 4 wasn't even intended to have its LTE radio used and LTE really didn't impact my battery. It felt like it lasted the same as it did before I enabled LTE on it.
Possible Sprint Fix
Customer: Is the SIM device specific? I reused the one from my Note 3. I have seen other information that the SIM's for the Nexus 5 are device specific.
Mitchell C.: Yes, you can get a SIM for the Nexus from a nearest Sprint store. I can fix an appointment for you.
Customer: so they are device specific?
Mitchell C.: Yes, they are.
Mitchell C.: We've come across a lot of these issues today.
Customer: SO just to be clear, I need to ask for a SIM for the Nexus 5?

Well, I got my sim card from a sprint store 2 days ago and I am still having issues. I have been emailing sprint care but no luck.
I hope they fix this soon! Maybe they gave me the wrong SIM? Idk
Doubtful Mitchell knows what he is talking about. People have used HTC One SIMS and GS4 sims and have LTE. But, today is the big day the Sprint phones go on sale. Will be interesting to see if any of those people have the issue.

Still stuck on 3G after activating around 72 hours ago.
To follow up on the Nexus 5's "special" SIM card. I'm also skeptical about this. I'm using a SIM from a GS4 (part #: SIMGLW206R) which is the same SIM mentioned in this post about activating the Nexus 5 on Sprint: http://qbking77.com/google-nexus-5/activate-nexus-5-sprint/.
However, I called a nearby Sprint store to ask if they had any SIM cards available. They said yes but when I mentioned the Nexus 5 the representative seemed to think there was some additional procedure for coupling the phone and the SIM. I don't know any more about this. Could be misinformation of course.

[Q] Galaxy S3 I535 No Service After KitKat Flash (4.4.4)

Hello everyone. I was hoping that some of you that are more knowledgeable about this stuff could help me out here. I recently flashed from CM 10.2 to KitKat (4.4.4), which everything went smoothly for the most part. However, I've noticed that my phone constantly has no service. I should probably state that I live in an area with very low service to begin with, but prior to the flash I was able to get at least a bar inside my house. Now, I'm unable to get anything.
The first thing I could think of to check was my settings in the phone. The data is enabled, CDMA Roaming mode is set to automatic, CDMA subscription is set to RUIM / SIM, and the Preferred Network Type was Global. I wasn't familiar with the global setting as I was used to seeing the LTE / CDMA / EvDo options there. So, when I clicked on it, it now gives LTE, 3g, 2g, 1x, and Global as options. I tried changing it to 3g, but the changes would not save that way. The only way I could get them to save was to power off the phone, take the sim card out and put it back in, and then reboot and switch them. Once i pick a new setting (which is now set on 3g), it locks it and I can't change it again without removing sim card.
When I look in About Phone > Status section, I'm seeing the network says searching for service. The mobile network type is unknown. The service state is out of service, and the mobile network state is disconnected.
Is there anything I can do to fix this issue? If so, I would truly appreciate any type of guidance you guys or gals could give me. Thanks!
I didn't read your entire post but myself and several others have reported signal issues after 4.4.4 flashes on all different ROM types. I think 4.4.4 is just picky about what firmware and baseband you're running. I flashed a few different RPM packages too but in the end I got lucky flashing the BLK3 modem and it seemed to fix my issues. I had noticeably poor signal strength most of the time and a couple times I would look down at my phone and I'd have no signal at all.
Maybe a dev or expert can shed some light on the root of the issue. I don't know enough about under the hood stuff to make an expert diagnosis.
Edit: The unanimous fix that everyone appears to agree on is to flash the MF1 AIO (all in one) package and then flash the ML1 modem only. Problem is finding a legit source for the MF1 aio package seems to be up in the air.
Like I said though, I didn't even do this. I was just trying all kinds of combinations of modems/aio's/ and rpm's and I got lucky. 2 days now with a solid signal at all times. LTE speeds are blazing too, 45 down and 10 up.
Check ur imei number. Or flash a backup and see if that fixes ur problem.

Like I said though, I didn't even do this. I was just trying all kinds of combinations of modems/aio's/ and rpm's and I got lucky. 2 days now with a solid signal at all times. LTE speeds are blazing too, 45 down and 10 up.

Can you share the specific steps you took? What worked for you and where can we download it from?
thanks!

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?
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!

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 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...
