[Q] Data/signal issue - LG Optimus 4X HD

Hi guys, this is my fist thread but I've been reading this forum for... I don't know, maybe 2 years.
Well, I have an issue that I can't resolve. I have to reset my phone a lot of times until "catch" the signal and the data connection. And sometimes the phone have signal but doesn't have data connection and the apn disappear...
The problem is presented as follows:
- Reboot my phone: no signal and the network operator is "UNKNOWN|MOVISTAR" (movistar is the brand the f*cking company). This is the most common.
- Reboot my phone: signal and the network operator is "MOVISTAR|MOVISTAR", I can receive and send messages and I can do calls too but the phone doesn't have data connection and the apn configuration is blank and I can't add any apn configuration because this no save any change.
- Reboot my phone: signal and data connection works fine, the network operator is "MOVISTAR", the apn configuration is right, I can change and save any change. This is the less common =S
I've tried:
- baseband V10A/B/H. V20A/B
- a lots of differents rils
- a lots of roms (just works fine with JB roms and stock)
- 2g and 3g
Well... that's my problem and I can't resolve it... Sometimes I want change my phone because this is a f*cking sh*t.
Sorry for my english. If you dont understand something, please, let me know.
thx so much!!
Bye.

Maybe the problem is at your provider.

Verry weird connection problem.

I have this weird problem with data connections. I couldn't find anything simular to this on the forum.
My provider (vodafone NL) does supports umts & 3G, I got a full data subscription, and the area i'm in is fully covered.
Now if I go to Settings - Phone - Band there are 2 different settings you can tweak; 'Network Type' and 'GSM/UMTS Band'. Those are standard set to 'Auto'. With those settings my phone says it has 3G connection (above the indicator bars and an icon), but i can't make any calls or get any data from the network. sometimes it also says the server ended the connection, but it still remains connected.
If I set Network Type to GSM, I can make calls, but only connect trough gprs wich is waaaaay to slow for me.
Setting it to WCDMA won't give me a connection at all. Turning HSDPA on or of doesn't make any difference also.
I figured updating my ROM would fix this, but it didn't. I tried different roms.
Is this a known problem, and more important, is there a fix for this ? It is driving me crazy !!
little more info;
ROM version : dutty's WM6.1 WWE
Radio version : 1.64.08.21
Protocol version : 25.74.40.02H
HTC branded Tytn II
Any advice is very welcome !!
Thanks in advance
i keep mine on auto but use bandswitch to switch between edge and 3g or some people gprs to 3g,sounds like a proxy issue since u wouldnt make calls on the wrong band,gsm works for calls so that part must be right so it has to be your internet settings and/or proxy
I checked the (proxy) settings on the website of my provider, and it seems to be okay. Those are settings for gprs tough, but it seems to me it should work as well for umts. It are also the settings the device initialy chooses for my provider..
I was thinking, might a radio update do the trick...? I did read somewhere that has to do with connections..
not necessarily, radios are more so driver issues for hardware such as gps,bluetooth,wifi,keyboards and cameras. i highly doubt another radio could fix this one since i never came across this with any combo of rom and radio before
Well then I don't know anymore what to do. It is probably a hardware related problem so I'll have to make a phonecall to HTC.
Thanks for the advice dyetheskin !
If someone does have a solution... still happier to get it fixed myself !

I am having the same issue.
More wierd is that it used to work perfectly in the beginning and couple of days ago it started acting like this.
I called my mobile provider thinking it might be USIM problem, however it wasn't.
Now I also think it's a HW problem. Next week I'll take it to a lab and hopefully it will be an easy solution.
I called HTC Tech support 2 weeks ago, and they confirmed it was a hardware related problem. They had 2 simular cases before..
Well, at least they will repair it for free

[Q] [SOLVED] Can't Get Data (3g) need help

PROBLEM SOLVED - DEFECTIVE SIM CARD. Thanks everybody !!!
Hi guys,
I really need your help with this one, here's the deal :
1. just bought my second SGS from vodaphone CH last week.
2. the phone came with 2.1 stock
3. i was not able to get data connection (able to make phonecalls and sms, but no 3g)
4. my apn settings are correct (i have another sgs configured same way on same network)
5. decided to upgrade to 2.2 (JPH) hoped this would help - NO
6. updated MODEM & CSC to the SAME ones working on my second SGS - STILL NOT WORKING
what else could it be ???
THANK YOU FOR YOUR HELP
did you install DroidWall ?
Nope,
Never heard of that Apo.
Can it help ?

Here's what's there, can you see what is wrong ?
Try this, worked for me
This is a weird coincidence. I have (had!) the exact same problem.
My problem was when I reflashed my galaxy S with stock firmware back again, I lost 3g connection. Using a different sim (which supports only Edge) I was able to get edge connection but with my sim, there was no connection.
Here's what I did. It seems when you select the band selection to "Automatic" it somehow didnt get registered properly even though it showed up on the settings->Wireless and network->Mobile networks->NetworkMode. Even though it read GSM/WCDMA (auto mode) it wasnt actually the case.
So - type *#2263# on your phone to enter the Service Mode's Band Selection.
There see if first row is [1] AUTOMATIC[] OR [1] AUTOMATIC[*]
In my case it wasnt selected ie. there was no *. So I clicked on it and did that selection myself and baam!! H connection. It connected even before I exited from service mode.
I tried a 2g and 3g card after that multiple times and it connects properly to E or H from then on.
Give it a try. I am hoping that your APN is set properly.
Anup
Thanks for the help, but unfortunately this didn't work :-(
1. Automatic was selected.
2. Ive tried to play around with the options there and within the mobile networks.
Nothing works ... this is so frustrating :-(

Why didn't you just call Vodafone and get their help before flashing the phone If you already have another SGS configured same way at the same location with 3G, then chances are there is a hardware problem with the phone.
Anyways, try contacting vodafone, they might still do something about it (despite the fact you have voided their warranty by flashing).

The problem is that I'm not from Czech Republic. The phone was purchased there by a friend of mine and brought to me...

changing from H to 3G

hey guys
i been using this lg p970h for some days, and its weird cause it looks like suddenly losing data connection, the signal indicator is empty and is unable to join to any network.
The phone was locked to telcel so i buyed an imei code and now is working with iusacell gsm, but sometimes it just lost the signal and get APN ibox.tim.it that looks from italy. So i need to reset the phone and wait to check if it hooks with the right network.
Im using nova rom, do you think it could be related with the rom? or maybe a hardware problem?
I don't think Nova could be causing problem...its a time tested stable rom.
However, try factory reset once again, put your network on automatic selection and put in correct APN, it should solve the problem.
Btw, your putting the thread title, H from 3G, foes it signify anything with your problem? I mean its quite normal when your phone switched between HSDPA to HUSPA it changes ..
weird but it looks like the language has some relation.
I was using English United States, sometimes the phone lose the signal and after a reset it appear with italian language and with the APN for a italian provider, so i tried using Spanish Mexico, let see if it has some relation... may be the phone set the country using the language and use apn in relation to that ... weird.. weird..

[Q] S III mini network issue

Hi guys,
I own an i8190, baseband : I8190XXALJL and I encounter frequent network outage.
Although the signal strenght indicator shows 3-4 bars, I cannot be called, cannot call and data is not being fetched.
On battery usage app, the network is most of the time "green".
On any other phone around me (blackberries, iphones, SGS II and III), and on the same network the problem does not reproduce.
If I turn the phone to airplane mode, and then back on, I am able to call, send mails so on and so forth.
Does any of you have the same problem ?
If any of you updated to I8190XXALL2, is this problem still persisting ?
Should I send it to the service ?
I'm currently running the ALL2 baseband, but previously had both the ALJL and the ALK6 ones and didn't encounter any such issue...
Before sending it back you could try with a different SIM card, maybe yours is acting up (it sometimes happens, especially with old SIMs).
Seeing how nobody complained of a similar issue though, I don't think that changing your baseband will have an impact, but if you'd like to give it a try you can download original firmwares (that contain the baseband) from here: http://www.sammobile.com/firmware/. In order to install them, just follow the steps in the root thread.
Will do so. I'm going to pit-stop my SIM card @ Vodafone and let you know about it.
It's strange that this happens only deep inside buildings (eg. offices, malls, etc..).
When this happens, usually the data activity indicator disappears OR the S3 mini is using 3G frequencies (not H, not G, but 3G)
Just changed my sim card and the issue still persists...
It's driving me nuts. My feeling is that the S3 mini doesn't lock on a network cell when 2 are available with similar coverage.
Will upgrade to the latest build and let you know about it :banghead:

And now the handset runs XXALL2 from vodafone uk.
I'm curious if the phone will have that network issue furthermore.
Happy Holidays!!

So far there's no difference. Where I live the network coverage is pretty bad, but it doesn't "disconnect in the background".
Only at the office I can test it out for sure or inside massive buildings.
ci6i, go ahead and update; install kies (for drivers only ), get odin3 1.87 and flash it with XALL2 from samfirmware.
Lately I see there is XALL3 available for some asian countries.
I still think that my BlackBerry 9810 is a tank. unfortunately vodafone romania doesn't sync emails two ways via BIS so... :crying: I had to get back to samsungs...
Well, i understand to lose signal if network coverage is bad, but my phone gets "network stuck" in the middle of town. I noticed this few times: at job, the phone stands on the table near me, and i receive sms about missed calls (i have voice calls diverted to voice mail when unreachable). If i try to call or browse the net at this moment, it's impossible until i set airplane mode on then off. All this time, the phone shows full network signal and HSPA data connection.
I'll try to change the firmware after hollidays.
As mentioned above, try to change firmwares (to XXALL2), I've also noticed some network drops when I'm at home (however this is expected in my case), but when I installed this firmware, I noticed some signal gain (full on 2G and +1-2bars on 3G signal).
Hi again.
The same issue even on xall2
Just happened again today in a crowded place.
It goes to "3G" from "H" and then it's gone off the network.
Will try with XALL3 although there is a small improvement concerning "sticking to the network carrier". It seems it'a hard job to get a call when in coverage area...
If still no success, I'll loose my patience with this Sammy...
See ya!

You get SMS because they use a dedicated network bandwidth for this technology and apparently the S3 mini does not loose connection on this communixation channel.
It appears that S3 mini is dropping voice and data, but not sms and CB (cell broadcast).

LJL version. No drops. Sometimes when i am on edge of 3G coverage area

Hi, i also have the problem with vodafone Romania. I can't place calls or use data connection. After reboot everything is ok. I tried to switch to Airplane mode and back, but no results.
Same problem over here

Hi bogdangr,
I have the same problem with my SIII mini. From time to time, after working normally, it loses the H or 3G symbol and shows about two or three signal bars, but if I try to make a call or receive one the operation fails miserably. The airplane mode trick doesn't work for me, and I have to reboot the phone to get it working again.
I've updated to the latest official firmware, but the problem is still there. Have you found a solution for this or anybody has more ideas of things to try?
Thanks you all,
MFC
I'm on VF RO, too.
Crappy phone, what can I say.
If it can't follow a network where there is sufficient coverage...

Hi Miguel,
The only workaround for this issue (at least for me) is to keep it in GSM mode (no "AUTO mode", no "WCDMA only").
So the crappy phone won't have to switch frequencies and I can get phone calls (I start considering a luck when the phone rings...)
I'm on 4.1.2 now baseband I8190DXALL3 (latest on samfirmware) and still the same.
You just don't want to know how's everything downloading limted to GPRS
BR,
Bogdan
Does anyone know what's that *# code that enables service / engineering mode ?
I want to select on which network frequencies is the phone allowed to work.
I want to disable 3G mode and leave GPRS, EDGE, and HS(D)PA only.
The reason is that when the issue appears, S3 mini switches from "H to 3G" and "G to 3G" and then it's gone;
Although there are moments when it can fetch data with network on 3G coverage without problems...
The code is *#*#info#*#* but it doesn't work .
I don't think it's a good ideea to disable those settings. Maybe it's a temporarily problem and i know Vodafone is testing/launching 4G coverage.
For me, this network issue is happening once in a week. How often do you lose phone signal ?

I found out the service code but the RF setup is not "sufforted".
Vodafone has implemeted already 4G in selected areas but it's not about that. On blackberry, iphone and nokia this is not happening.
As a frequency... 3-5 times a day while I'm at the office.

I'm using it with Orange Spain. I will try using the phone this weekend with another operator to find out if the problem is operator related.

I tried to install an international Rom Vision-intl rom

I didn't manage to install the N910 f baseband on my device to solve the problem
