No 4G since the update

I applied the update late Friday night and have not been able to get a 4G signal since. I'm normally in a strong 4G area and had not had any problems like this in the past except for the nationwide outage of course.
I've tried battery pulls, toggling LTE off and on and even did a factory reset. I then talked to tech support and they did a few things on their end that were unsuccessful. They then told me to get a new SIM card but once again, no luck.
Tech support is at a loss to explain what is going on and has escalated it to the higher level of support. It can take up to a week for them to get to a ticket so I guess I'm SOL until they take a look at it.
Anybody else having 4G problems since the update?

I haven't applied the update but have been stuck in 1X all day as well. I also pulled the battery, switched back and forth on Rev A, and toggled LTE. Nothing. Was going to revert back to a saved ROM next. My wife's phone happily receives 3G.

Did the update Friday night and 4G is as strong as ever.

My 4g is also working. What is weird is when I loaded a ROM I lost all signal. I loaded another Rom and nothing. I had to load radio file in hboot and I was back in business.

yea in such circumstances I had reflashed the radio and it works just fine, give it a shot

Received a replacement today, popped in the SIM card and am back to 4G. No idea what happened but the update is definitely to blame.

Yeah I got mess up too with the new update. Had to get a new simcard today and it work ok.

4G working just fine for me also

glad you got it worked out. I would have reflashed just the radio to try and fix it.

Having this issue as well since yesterday (7/11). Loaded Th3ory 5.0 with the newest radio to two different Tbolts (mine and a coworkers) and we're both experiencing the same issue. Flashed different versions of the radio, including the newest one again and had 4G come back for a short period of time before all service was gone again. Not sure if its an issue with Th3ory rom itself and since I cant post in that thread until I make a few more spam posts about nothing to get my post count up, I figured I'd post it here.
in Mid-town NYC where 4g has never been an issue before.

I should add that I wasn't rooted.

What happens if you're Rooted and running a custom ROM and you do a SIM Card pull? I really want to try this method, but i'm scared this will force my phone to download the new OTA update and that i'll either brick my phone or run into some serious issues.

I have had trouble for the last two days getting 4G, never had a problem before.

don't think anyone else is having problems. Might be network issues in your area. Just flashed gingertheory 5.0 yesterday with the new stock 2.0 radio from the update and no problems.

I am having the same issues 4g is gone and only stuck on 1x

Make sure you check your sim and battery cover.

You dont need to pull out the sim card, pulling the battery is good enough. All it does is update the PRL.

I'm in the same boat.... I used to get 3-4 bars of 4G service at my home, now after the update I barely get 1 bar of 3G service. I have to force the phone to lock onto 4G by choosing LTE only.

SIM problem on my One XL (LTE)

Hi since I can't find a forum for the One XL I assume it's shared within this one.
I just got my One XL yesterday and it's been having what seems to be a SIM card problem. The phone will be normal sometimes but will lose all mobile connectivity suddenly. Is this a known problem? The connectivity comes back on its on but it could be after a few minutes or few hours. Apart from returning the phone, is there anything I can do? Note that WiFi works perfectly.

Yes sir that would be a common issue among the hox .

When you say "XL," so you mean an imported XL from Asia? Rogers? AT&T? The AT&T's the one having some radio issues. I don't think the Rogers' is. And if you imported yours there could be a number of reasons you're having connectivity issues.

@barryH_GEG: I live in Hong Kong and the One XL has the right bands for 4G and HSPA+.
@tyshemi: is there a software fix to this or is returning it the only option?

Gentlemen,
What the h.. is with this phone? I got it as well last Friday and I have exactly the same problem - it loses all mobile connectivity and only emergency calls can be done .. for which a SIM card won't be needed. It doesn't look like a software pronlem to me, it looks more like a hardware problem! I've seen this behavior immediately after I received the phone and I immediately went with the phone in a Vodafone shop. The guy did not look surprise at all. He took out the micro SIM for couple of times and after wards it worked OK. I went home and after couple oh hours it happened again!!!
@ HTC developers:
Gentlemen, are you joking with this device? What's going on in the testing team?
Indeed it is a LTE phone - and it is known already that there are lots of problems with the 4G software, but the SIM card not to be seen by the mobile? How could this be possible???
Please do something about this!
I will send back this device immediately!
Cheers

I myself have exchanged my HOX for this issue twice now. AT&T knows about this issue and refers to it as a manufacturing defect with the SIM card reader while not in a LTE area.

In Australia, we have this issue on our 32GB One XL. Apparently it's a particular version of micro SIM. One specific version has this issue, the other doest.
I've seen it happen a couple of times on mine since I got it. If it happens again, I'm going to put some very thing pieces of paper under the sim card to make it marginally thicker and press firmer against the contacts when it's inserted.

Hi guys,
Just to give you an update about my HTC ONE XL. Unfortunately, I have only bad news about it !
I went yesterday to Vodafone shop and they changed the micro SIM card. They gave me a different one - also a brand new one, and I have the same problem, the phone loses the connection with the SIM card. Since yesterday it happened already twice! I've seen some discussions here about the WiFi. Just to mention that in my case the Wifi can be used, only the network is gone and stays gone until I restart the phone.
HTC ONE X also loses the connection with the SIM?
My micro SIM card does not have a 4G subscription anyway..
Cheers

Try putting tape on the plastic side of the microSIM to see if maybe you can get a more solid connection?

My One XL would keep loosing reception and saying "no sim" even though it was clearly working. I deactivated my SIM pin and it seems to have stopped dropping out and saying "no sim" Give it a try.

I have One XL and I have no sim issues, it could be the piece that you use. As for the signal drop, it does happen to me sometime, and I think it tries to connect at LTE then goes back 3G. Try to force 3G only then try.
Setting on network menu could help too. Try *#*#4636#*#*

Been having the same issue and found it in the logs. Not sure if other people are seeing the same thing though. Post with info.

Hi guys,
I sent back the phone last week and yesterday I got a new one with a "newer" IMEI. Since yesterday, the phone did not lose the connection with the SIM card.
I was told that, indeed, some of the first HTC ONE XL modeles released on the market had the problem described by us on this forum/topic. The nature of the problem, hardware or software is not known to me so far but I believe it's a bit of both..
Cheers

This happened to me and updating radios to 1.88 or higher fixed it. did not work well with 1.85 radio. Radios dont come with custom roms. They have to be installed separately or with a ruu. There is a radio thread in development. You must be rooted. Ive only had 1 person tell me they still had problems after updating.. if it doesnt fix it, get another phone. Its a legit reason. Main reason for a phone is to make calls. kinda hard to do that with no mobile connection. :crying:
Edit: here is the radio thread. 1.88 or higher. 1.88 is my favorite. The telus seems to be great also. http://forum.xda-developers.com/showthread.php?t=1694012

and jsut in general the network fluctuates a lot on this phone.

[Q] Nexus S 4G - DATA DROPS

I have been having this problem with both of my Nexus S 4G ever since I got them 2 months ago.
My data drops out frequently and takes a while to get back up. If I have 4G enabled, then I have to manually reconnect it as it will not do it on it's own. This happens inside AND outside. Driving down the road or just standing in one spot.
I've tried all of the radios (basebands) and about 7 different ROMs and versions.
I've refreshed the data profile, PRL, and even tried the roaming Verizon PRL and Hybrid PRL.
Gone back to stock and tried everything from scratch. Still the same problem.
Dallas/Fort Worth Area
Network: Sprint
Baseband: D720SPRKE1
PRL Version: P:40447
I contacted Sprint and they just told me to update the profile & PRL.....
Any suggestions?

I'm not familiar with the CDMA nexus s, but are you able to change APN's? At one point I'd be able to connect to 3g (I have an I9020A), but every minute or so it would drop, so I fixed up the APN's for my carrier.

iv had a few data issues
forcing PRL and account updates has fixed it a couple of times
i'v bought used phones that iv had
to have sprint force update
im on LC1
[altho i cant tell any significant difference here]
and my prl is 61086
[a business account]
im currently on slim
make sure your mobile network
is set to roam
is not set to home only

Am I the only one with this problem? As I'm typing this I lost data but still had 3 bars. I never drop calls but only data.
Help please. This is driving me nuts.

it then fails to re-acquire the IP address.
look in your status and see if you still have an IP

4G is worthless here...
i dont even bother with the switch
does it do the same thing if you disable 4G?

I almost always have to use 4G (if possible) since 3G speeds are slower than dial-up.
I've tried rebooting and leaving 4G off, and still the same. Even tried going back to Gingerbread.

I have the same problems. From what I understand, its a problem with the hardware. I can confirm that's probably the case, because I've tried many different ROMs (stock, cm, etc...) and they all have the same radio issues (3g/4g and wifi)...

I have an NS4G in the DFW area and haven't seen the issues you're reporting. I'm currently on 4.0.4 with D720SPRLC1 baseband. Maybe I'm just lucky and have a good signal at work and home. It's very rare that I find an area of DFW where I don't get any data signal at all. Not sure what to suggest.

I get random drops too and i hate it. My 3g speeds are fairly good even above 1 mbps. Highest i ever got on 3g was 1.51 mbps

Mine will lose data if I'm in a coverage free area for an extended period of time, when I'm back in range 3g icon will show up just never reconnect. A reboot fixes it

Certain Areas
There are certain areas where I live that data just disappears. Although this is just a network thing I believe. It's weird though when I am driving it's like a 10 second drop and then all is good. Hope you get a solid fix!:victory:

Backup 4g Partition
REMOVED - was a bad idea.

I've actually replaced BOTH of the phones with brand new NS4Gs and they shipped with ICS.
Still the same problem.
This is driving me nuts. I was driving and trying to download Maps for the new phone from the Play Store and it took 6 tries. Kept saying RETRY.
What I've come to believe is happening is:
When 4G connects, 3G disconnects. When 4G drops (which is does frequently), 3G has to reconnect.
***Is there a way to keep 3G "on" in the background while 4G is connected?*** Maybe a way for the radio to transition back and forth?

Some calls not coming in and late texts

Had this in the wrong section so moved it.
Not sure what this issue could be. A lot of people say every so often that they call me back to back at times. I get no missed calls notifications. Same with text sometimes. Not sure if its ATT or what. Happens at home and when I'm out. Anyone else experience this?
I'm rooted, Rohans B5 kernel, clean flash to King Kang. This has been happening for awhile before this ROM. I'm on WiFi and the signal bar is full

I had a similar situation recently where I was receiving texts, but no one was receiving mine. Found out AT&T was in the process to switching LGE on for a number of towers in my area, so I think service was semi-disrupted during that time. Fyi, I was running CleanRom 5.0 with BeastMode 3.4 Kernel.

I think I responded to you in the other thread thought I would follow up. So ATT did the reset on their end issue came back in about a week they said they wanted to replace the SIM card, and if that doesn't do the trick they will replace the phone. Fortunately it is my wife's phone which I had already returned to stock over the issue.

I had the same thing at my house a while back. It happened off and on for a couple weeks, then never happened again. Think this was due to network repairs or upgrades, like the previous response suggested. If nothing has changed on your phone, and it was working fine before, than its a network issue.

[Q] Little to no signal and no mobile data access

Well I'm on the latest CM nightly (CM 10.1 -20130312) and I just came from CM 10. I tried CM 10.1 before but I had little to no signal and I've decided to give the latest nightly a chance and well, I still have the same problems as before. I flashed the 3.18 radio on it and it literally made NO difference at all. I hate the AT&T variant of the phone. On the CM 10 version I didn't have this problem but there were times that I'd go half an hour to a full hour without getting any texts and then they'll all come in at once (and I know its no coincidence because some of those messages contain people wondering why I haven't replied yet). So can anyone help me with this problem please?? I really like CM 10.1 but not having any mobile data and an even worse signal is a REAL deal breaker for me.

I was having the same issue until I went into settings and changed it to GSM/WCDMA.

I used to be tech support for att. Obvious question: has this happen before? Now to put my xda hat on. Did you change APN settings? Is this the only rom you flashes? Also call att (611) and have them cancel registration. This basically kicks you off the network and bring you back on. Sim cards are not the issue as the are unable to determine signal strength. Hope you get it fixed.
Sent from my Carbon-ize Evita using xda-developers app

I think it has something to do with the 3.18 radio. I never had problems until flashing it. I have tried multiple roms. Sense based and aosp. It happens on both although it seems to be worse on aosp. I went out of state and lost signal completely while running the latest Chameleon. I went into settings and as soon as I stopped it from searching for LTE it went to full signal. Maybe a tower upgrade issue? 3.18 radio issue? I guess it's something for devs to look into. I know not all towers are the same. 3.18 maybe conflicting with the area he is in. Somebody will get it figured out lol.

That's just weird. I flashed 3.18, and still get the same coverage (4-5 bars, 6mbps data). I don't see how it can effect you. The device is dual HSPA+/LTE. So if the device cannot find LTE, it will always back (circuit switch fall back). Even when I went to an LTE area (Nashville, TN), it still work perfectly. Could be something up with the physical radio inside of the phone. The LTE towers are suppose to be backwards compatible, but we know how companies can be. If your device is working in one area, and not the other, then it is a tower issue. Even though AT&T may find that their towers are ok, it is a tower issue, and there is no doubt around that. Now if it just gives you random coverage, no matter where you are, then it is the phone itself.

Having the same issue on CM. Just tried changing to WCDMA and my signal doubled. That is weird but thanks you guys.
