Hey Guys,
My phone got wet. Dried it all up. Everything fine. EXCEPT that it will only connect to T-Mobile's network when 2G only (GSM only) option is enabled. But when I selected 4G only (WCDMA only) it will get stuck in Searching... and when I try to registered to the network by going to Network operators -> Select Automatically or Search now. Also, when I select 4G/2G (WCDMA/GSM) it will only connect to 2G. Any ideas? I have Odin'd back to Stock ICS, and to Stock GB. No luck.I also always had full signal with 4G only (WDMA only). I also tried my SIM card on another 4G phone and it worked perfectly. Everything worked.

Hi,
I've been using my desire for a while now. Today I switched from provider. At first everything worked fine. Then I reported the phone and I didn't had any gsm network. I tried another sim and everything worked. I tried the "defective" sim in an other phone everything worked. I got a new sim from the provider and tried again. Same story, initially it works. I reboot and no connection anymore. Now after some fidling with the settings I found that when I disable wcdma and turn on "only GSM" the phone finds a network (only gprs) and works. If I put it in auto mode, it gives no connection, in wcdma it also gives no connection.
The provider has no idea, HTC support Belgium has no idea. Can somebody help me witter this?

Have you set up your APN settings correctly? Chances are you have not. Also I find my internet connection to have problems when I changed providers and sim cards, however I installed a completely new rom and wiped everything and redid all the APN settings and it works now It still a bit dodge, but I can toggle aeroplane mode on for 10 seconds, then off and it works.
my phone can not connect to 3G networks in most of our city, while it used to work just fine in these same places. at first i thought there must be something wrong with the carrier's base stations. but today i tested my SIM card on another LU6200(Korean version of Nitro HD) and it works perfectly both on 3G and 2g networks on that phone. but when i put it back into my phone, it can only get 2G signal. if i set the Preferred Network Type to WCDMA ONLY, it got no signal with just a cross on the signal bar. i have to put it back into GSM ONLY mode to receive signal.if i go out, i can get partial 3G connectivity here and there, but not consistently. sometimes even if i have full 3G bar signals on the status bar, i can not make calls or connect to the internet.i've got this problem probably after i tried to forcibly go into the Phone Info menu.i got repetitive " the process com.android.phone has stopped unexpectedly" promps , and i just ignored it and tried again. now ,2 options are missing from the menu, LTE/WCDMA/GSM and LTE Global.in place of them, it's UNKNOWN. i already tried flashing KDZ package of no avail. Does this mean a hardware malfucntion or software glitch?Please help!Thank you in advance

LG NITRO-N XDA APP
Well you do HAVE GSM only selected. THATS 2G(EDGE)
for 3G you would need to select WCDMA

no, if i select wcdma, i got no signal.it should be hardware problem
I just got a N7505 and with Rogers in Canada.
Data connection is sporadic. It will not work for few minutes occasionally and it is getting annoying.
I checked the APN settings and they are correct.
Any suggestions?

What u mean for "SPORADIC"? is it mean the data connection is on/off? how about your sim card line? is it 3G or 4G?

Sporadic as in, it sometimes works, and sometimes not.
Wifi is fine, but mobile data (4G/LTE) is not. With the same SIM card, mobile data (LTE) works fine on LG Optimus G.

In my case... my sim is 3G..but i've set in Mobile Network is "LTE/WCDMA/GSM (auto connect)" at first.. then i found out my data connection same with u.. sometimes on & off... telco company advise me change to "WCDMA/GSM (auto connect)". Since my operator line area still not available for LTE service. After i changed it.. then works fine.
U try to change first, then we'll see..is it ok or not.
Here in U.A.E i was facing the same issue as a work around i go to SETTING , MORE NETWORKS i then MOBILE NETWORKS and in NETWORK MODE manually select WCDMA/GSM as off course i wont able to get LTE but data speed is much better and no signal problem what so ever.
My carrier does not use WCDMA, just LTE/GSM.
Is there a code from dialpad to get into backend settings? For instance, with my other phone (Galaxy Note 1), I can dial *#*#4636#*#* to get into phone settings for more options for network connection.
Hello there, I'm in need of your help again.
My SGH-M919 has a problem, it cannot connect to 3G/LTE (Not even EDGE). My carrier uses the 850 mHz band for GSM and 1900 mHz for UMTS, so the phone should be able to use them. The thing is, it doesn't. It only connects to GPRS and the signal is very erratic and weak (Usually 2-3 bars). Sometimes I get SMSs from my carrier saying that I missed like 5 calls when my phone never rang once. I live in a zone with good 3G coverage, so it's not the signal.
I'm currently rooted on Android 4.4.4 (NH7). I already tried selecting "1900 WCDMA" in the *#2263# service menu but that only causes the phone to lose all the signal (And it's a problem to change it back, without signal the service menu doesn't work and I cannot change the Network Mode in Settings).
I've tried to select "WCDMA only" mode before, but my signal just goes to zero (The circle with the slash) before changing back to "LTE/WCDMA/GSM (Auto connect)" automatically.
I also cannot use the Network Operators option. Using "Search now" makes it search for a few seconds before showing the message "Error while searching for networks". The "Select automatically" one shows the message "Unable to connect. Try later" and then connects back to my carrier (Movistar)
My APNs are configured (They did it themselves when I inserted the SIM, but I've configured them manually before). The SIM card works, I tried it in another phone and it got 3G immediately, I also tried another SIM card on the GS4, but the result was the same. Someone told me to upgrade to the latest firmware (NK2) while someone else told me to flash the MDL modem. (Is that even possible? I read something about KNOX blocking all downgrades after 4.3).
Since I couldn't find any direct solution to the problem, I'm recurring to you.
Thanks.
P.S: I didn't change the LTE Band Preference option in the Service Menu because the last time someone messed with it, my IMEI/Baseband went completely nuts, I thought the EFS got corrupted, but they magically appeared everytime I enabled the Airplane Mode (So I was able to select Automatic in the ServiceMenu and they got fixed). Also, I don't live in a LTE area although once during a very strong thunderstorm, I got 4G for a few minutes before going back to G).
*bump*
Any ideas?
Did you put a check mark in data roaming?

I've tried with and without it, it doesn't make a difference anyway.
Does it show you have an ìmei # other than all zeros?
Don't post it just a yes or no.

My IMEI is fine, the phone connects to the carrier network but it stays on GPRS (and the signal is always dropping)
Update to full NK2 firmware and see if that will fix it

I'll try that later. Will I have to re-root and re-install TWRP after flashing NK2?
I have a similar problem with my M919 on the Tmobile network. Using the *#2263# menu I can not get mine to work on WCDMA (4G) either. I can chose GSM /LTE only and my phone works normally but no 4G signal. If I chose WCDMA I get no signal. I can see it trying to connect and immediately dropping the signal. If I choose any option with WCDMA included it has erratic signal and will lose the signal most of the time when I try to make a call. So basically I have the choices of GSM only or GSM/LTE only. Before I discovered the secret menu I was stuck with GSM only in the phone's settings. This has been going on for months. Tmobile changed my SIM card and it didn't help. I've rooted and unrooted my phone (using autoroot) and even tried different modems (even worse signals) and now am back to stock rooted NK2 firmware and modem. I have given up and decided to get another phone (not an S4). My wife's S3 gets great 4G signals in the same location by the way. I wonder if anyone knows why our phones can't use 4G. I am beginning to think it's a hardware problem but I'm way out of warranty on mine.
Hello,
since I updated my OnePlus 3 to the newest Resurrection Remix I have problems with LTE/4g. If i activate Mobile Data, i only get EDGE with a low bandwidth. I called my Mobile Provider and they said, that in my area LTE is working perfect. I eject the SIM Card and placed it into another smartphone and after two sec. i get LTE/4g with a high bandwith. A factory reset, returning to Stock Rom, deleting the APNs didnt work either. Is there any soultion fo this issue?
Maybe I crashed my modem ? Is it possible to flash everything back to Stock ?
Thanks
type *#*#4636#*#* in your phone dialer, phone info, scroll down and set prefered network type to LTE only. you will be unable to call while in this mode so do not have it turned on. just test it if your 4g works

well then your phone is broken or your service provider is messing up. but you already called them and they said that it was all ok on their side. so that means there is certainly something wrong with your phone
