Hello! Been using my phone for quite some time with LTE activated and working fine. Flashing custom roms and trying out fresh modems i suddenly noticed that I can only get E, H and H+ data connectivity. My LTE connection is gone. I've already checked with my provider and they said that my account is still activated. I went back to stock rom, gone through all the settings and still no LTE. So I'm wondering is it possible to fry the LTE receiver chip on my phone from over use? Are there similar incidents out there? Is there a fix?

If you dial *#*#4636#*#* do you get the testing menu? If so, go into Phone Information and check you are set to LTE/GSM auto or similar.
Otherwise, maybe you have flashed an incompatible LTE modem?

I've not had a 3G/HSPA signal on my N4 for a while now. Trouble is I don't know exactly when it happened as I'm generally on either WiFi at home or at work, where I know I can only get Edge.
I've tried the usual check the APN, *#*#4636#*#* and nothing's jumping out at me (if I tell it to use WCDMA only I get no signal at all).
I'm wondering if it was the 4.2.2 udpate and wonder if I've got the wrong radio - so the question is does anyone know what radio I should have on my N4? I'm in the UK on Vodafone, but I got the phone from the Play Store.
I've tried searching but the N4 seems to have had so many signal issues it's difficult to sift out the relevant stuff
I'm not rooted but I'm happy to do it if needed. Already tried a factory reset so nothing to lose!
Cheers,
Dave
have you tried a different sim card? thete isnt a specific radio per region, so thats not a problem.

Yeah, sorry, forgot to say. I tried the wife's SIM (different operator) and same issue, only got a 2G signal.
I was thinking it might have been an issue when they updated it to remove the LTE "feature"
Even i have the same problem . I am from India and also have tried a couple of sim card . Im not able to get 3g signal at all . Anyone pls help....
i have the same issue solved whit RMA my first nexus 4 was defective, my new nexus 4 changed in warranty now works well
3G/HSPA networks
participles ipntsly
I started having the same issue today in Atlanta. Had another T-Mobile HSPA phone sitting next to mine with 4 bars while I was on Edge. My N4 is < 1 week old and seemed to be OK but now I can't get it on anything other than Edge.
I've checked my APN settings, reset the radio, turned data on/off and reset the phone with no luck.
Any advice?
Update: Just got mine working, here is what I did.
Wasted 20 mins talking to Google and T-Mobile. (I don't recommend this step.)
Type in *#*#4636#*#*
Scroll down and change 'WCDMA Preferred' to 'WCDMA Only'. At this point my bars switched from Edge to HSPA.
Now, undo the change and put it back on WCDMA Preferred. Make sure it still has a 3G or an H next to your bars.
Exit and enjoy the fast phone.

This worked for me.. thanks
I am having the exact same problem as Dave. My n4 has just stopped connecting to WCDMA (H).
I have tried re entering my APN's, Turning on/off mobile network, Airplane mode, rebooting and removing the SIM. From the test menu I have tried WCDMA only but I lose my signal completely and go to emergency calls only. If I use either GSM only or WCDMA preferred I can get a 2G connection but nothing more and when on WCDMA preferred it can lose connection completely as well.
I am also with Vodafone UK.

I tried this as soon as I put WCDMA preferred I lose signal, I have tried doing this in several locations as I live in the country, tried at my school where my friends get H+ and I still lose connection. tried going back to stock still the same issue
Can someone fixed this problem? "WCDMA only" mode make my N4 lost signal.
Sent from my Nexus 4 using XDA Premium 4 mobile app
Getting bars on 'GSM only'
I have got the same issue on my Nexus 4, and I still don't understand how it happened in the first place. I updated a bunch of apps before going to bed and remember waking up to no signals on my phone.
Currently I only receive signal when I go *#*#4636#*#* and set it to 'GSM only'. Any other configuration (WCDMA preferred, WCDMA only, etc) results in loss of signal.
I have tried the following with no luck:
1) Restored Factory Settings
2) Installed an older version of android
3) Flashed multiple radios
4) Steps listed on this thread
Can anyone help me out with this?
Thanks
I have had my SGS4 since June running CM with no issues connecting to LTE, but I recently tried PA android and could only connect to H+ as the fastest network connection and Network Mode defaulted to WCDMA preferred and could get no network connection at all if I changed from that. I tried going back to CM and still had the same issue. Reflashed stock using Odin and have since tried Shostock and CM again, but still cannot connect to LTE. I also tried my sim in my Nokia Lumia and get LTE on that so there doesn't seem to be an issue with my plan or sim card.
Does anyone have any ideas on how to fix this?
Sorry if this is a silly question, but in the interests of ruling out all possibilities: Are you sure that it's the actual connection, and not just the icons? Maybe you're used to seeing a 4G/LTE icon that isn't used in another ROM.
It wouldn't really make sense if you went back to CM and that issue persists, unless an icon setting is preventing you from seeing the icon. It might be worth checking the settings, because as I recall there are plenty of ways to customise your icon area.

I am sure it is LTE and not an icon issue, Before flashing PA I was getting 30-40mbps and now the highest data speed I can get it 3-6mbps. If I set the network mode to GSM/WCDMA/LTE (which is what it has always defaulted to before) I cannot connect to a the AT&T network until I set it back to WCDMA preferred. As I mentioned in my previous post it is only this phone, with the Windows Phone I tested using the sim worked fine on LTE. Also as I mentioned this happens on several roms, and has continued after a complete reset to the factory rom using Odin.
Hi, I have D801,
I recently started to have this wierd problem, where I would lose all my signals completely, and comes back on, just without an LTE (regular 4G).
after this, if i go in to network settings, it is defaulted to WCDMA only or WCDMA preferred, instead of the ones with LTE in it.
no matter how many times I change this, it keeps going back.
I literally live right next to the tower.
I did not have this problem a day ago, I don't know what is causing this problem
i have flashed
http://forum.xda-developers.com/showthread.php?p=49449195
this on my D801, and this is the only thing I did before having any issues.
or maybe it's something else.
APN setting looks normal etc.
can anyone tell me what to do ?
I tried going back to completely stock, and the problem is still there.
I used this method.

is there anything in this procedure that doesn't get restored to stock?
HELP!
I was at a location where the network reception was bad and I lost signal. My phone has not been having network signal since then. Signal strength 0.
Hi everyone !
Lately I went to a place were 3G/4G was not reachable and it is there that i noticed that my brand new Moto X play couldn't get any connection in 2G (GSM) mode even if the place was fully covered with 2G/EDGE (GSM)...
In 3G/4G there is no problem only on 2G (GSM).
I tried in the settings to put 2G (GSM) only and I can not get any signal even now that i'm back home ....
I tried a factory reset from the recovery it did not work :crying: Do you have an idea on how to solve that problem ?
I also tried to use the sim card with another phone in 2G (GSM) and there it works fine with maximal signal ....
Thanks ! :laugh:
Hallo,
I did a test and I got the same "problem".
Turned 4G into 3G...no problem.Still connected..
Turned 3G into 2G....no signal.
Turned 4G into 2G..no signal.
You can try to switch networktype in *#*#4636#*#*
No time for me now....I will try it later on the day.

I just tried it and turned the networktype to "GSM only" then i got no signal just like before. If i try to use another type like CDMA/GSM it connects to 3G and works but still the problem with the GSM/2G....
Hi guys. I'm not experiencing this problem on my XT1562. switching between bands is fine and working on my device. What kernels are you guys using?
I'm using the stock kernel, I just flashed the OTA (6.0.1) from the stock recovery
Same Problem, more information
For my Moto Play X I have a very similar problem:
4G works, but 3G and 2G do not. If I'm connected to a 4G network, I see that there is reception and can use all data transfer functions. But when I want to do a call, I get a timeout. When I'm in a place where there is no 4G network available, I see that I don't have signal - but the network is shown in the list of available networks for manual selection.
As I have a dual SIM variant (stock ROM, not a custom modification or "upgrade") my second SIM does work like a charm. I tried now and swapped the SIMs - and it seems that just the SIM1 slot is having those problems. The same SIM also works perfectly in the second SIM slot.
I also tries to reset just the network settings (an option provided by the stock ROM) but this didn't change anything.
Next step I'm currently working on is doing a factory reset - will take a while until backup and restore will enable me to see the real result. I'll keep you up to date....
UPDATE: factory reset didn't change anything - will send phone to repair now. :,-(
So the thing is, a month ago my note 4(6.0.1) for some reason stopped working in 3G or 4G.
Things I've done in order to fix it:
- factory reset
- updated to the latest baseband
- changed sim-card to latest possible
- changed carrier
So right now I'm using a different carrier and have 4G and 2G, but when I switch to 3G, for some reason I can't use internet at all.
Is there a possible fix for this issue? Can this be a hardware problem, considering that 4G and 2G are still fully working?
Also, during 3G usage I've checked service mode menu and it says GMM State: Limited Service.
When I use 4G or 2G, it doesn't show this.
What can this possibly mean?
thanks
