HELP: impossible to receive phone call when 3g is on - LG Optimus 4X HD

hi,
since few days I got the following issue :
when the 3g connection is on, I cannot receive (or I cannot make) any phone call as the device completely loses the operator signal and some times I have to reboot it to restore the gsm signal. I noticed tha this happens only when the status bar displays "3g" icon, when in " H+" it works properly.
I put the sim card in a different device and it works, so it is not a network problem.
the problem is that I got this issue with a custom rom ( lg stock based) and then I flashed cyano 11, but the 3g issue is still there!
Could it be an hardware problem?
Has anybody any Idea how to solve?
thanks

What kernel you use?
I've been using some customROMs and never had this problem.
Try a factory reset, flash again KDZ and try other customROM, like BeanStalk and test another kernel (I prefer iodak 9.95)
The only way to find out if it is a hardware problem is testing.
Best Regards. :fingers-crossed:

There has been a discussion about this already somewhere, I remember @Flying_Bear participated too. For me personally network doesn't work at all (no calls, texts or data) if it's displaying 3G, no matter which roms I use. On H or H+ it's working properly.

my Kaiser do not work with 3G only works on GSM

Suddenly it had happened; NO 3G nor GPRS data transmission. I can see the 3G sign , but when I make calls the phone disconnects; when somebody call me, he received a message that my phone is off line. Only when 3G signal is on. But when normal GSM is on, everything will be OK. My phone can not get data from the internet, even though it shows that is is connected. I tried all of the above solutions to fix this problem but no helpand sometimes it shows 3g sign but as soon as i try to call some1 all the signals are gone.. I tried to hard reset and try it before installing any software, no help. I tried mostly all available ROMs and Radio ROMs; even the original, but not fixed. I do not what to do. Now, I am using the phone with GSM only, NO 3G. Please help!!!

Hi there nunu,
I had the same problem, went back to the store and nope not a known problem.... So I started to troubleshoot this
1. normal G connection
2. 3G appears or even H
3. signal lost and after 30 sec. the cycle starts again.
what worked for me was the changing the of the radio version. I am currently in the Netherlands and here the NEON_Radinly_1.65.24.36 works fine, I confirmed it by loading a rom with a different radio in it and the result was again the same.
hope this helped in any way...
Let me (us) know.

life is good, but life get's much better with a Kaiser
are you trying to connect with [email protected] / cingular1 ?
this is the kinda information you should have put in your first post
I use the above and have zero problems in Philadelphia
My 3G went out for like a day here (Phone only worked on Edge), then it started working again. Cellular carriers do have outages from time to time. Has it been a long while since it stopped working?

Flash to a different compatible radio. If you do not get 3G/H service back, then you have a hardware issue with your radio, and will need to have the phone serviced.
what newtwork are you on?
have you tried your sim in a different handset?
what happens when running in gsm only mode?
in settings phone network change selection to manual and tap find networks and reselect network (this is known as a manual roam) does this make a difference?
Same here!, im in montreal, canada with Rogers, and in 3g doesnt work, it detects the 3G network, but as soon as i try to make a call or go on the internet it looses the signal and i have to go on GSM mode.
and i'm using LKDV12 but i still had the same problem on AT&T Original rom, and Dual V2.
Anyone?
Major problem --
I have been travelling round the world for a year and have the same problem, Have tried many radios, if I use 3G( wscdma) or auto band then the signal drops everytime i try to make a call, and no data is possible however if I use gsm only data and voice work fine, thease symptoms are on many networks, Chile, Easter Island,Tahiti, NZ, Fiji, Optus ( OZ ), and m1 ( singapore ),
Radios tried
EMO 1.71.09.01
Neon 1.65.24.36
1.65.21.18 ( att )
I even loaded the generic dopod rom + radio and it didnt seem to help.
Is it possible something low level has changed whilst doing all this flashing ?
Or could the Hard SPL affect something.
I always try to buy a 3G USIM in each country and test the sim in a backup G800 to ensure the carrier has enabled 3g data okay.
Phone is Kaiser ( HTC TytnII )
ROM is varied but and usually lorentis series roms -- L26 12 light atm
Symptoms, 3G icon shows but data wont connect, if you try to call radio strength bar drops to zero and cell communications are lost , sometimes reestablishes comms but often needs soft reset to band switch to work.
If 3G icon not showing all calls and GPRS data works Okay.
Personally I would not expect this to be a hardware failiure as many others are experiencing teh same fault and for working hardware to fail in use is more erratic in the failiure mode, but a low level register, or some other type of protocol corruption could easiliy be the cause......
The proven "high GPS current consumption in standby" issue is also present as it seems to be on all Kaisers but afaik the root cause of this was never resolved either .....
my Kaiser do not work with 3G only works on GSM NEED HELP

i have the same problem did you make it work how you set a gsm band instead of the 3g on the phone tks for your assis
dr.vogel
I have the same problem. Already had it with WM6.0 original HTC ROM (Finnish ROM, but language set to English). Then sent it to service. It came back, they said they "reapplied software or smth" and it worked after that. Then after 6.1 update again, the same problem (even with the latest updated Radio ROM).
When I set band selection to auto, it picks up 3G or even H but tends to loose it and definetly looses connection to network if I try to make a call. Can't take any incoming calls either.
It works ok when I force it to use GSM (EDGE for data) on Band selection tab, in phone properties.
I probably won't bother taking it to service anymore cause there is no local service here in Estonia, they ship it to Finland and it will take a minimum of 3 weeks...
... so I'm waiting for Xperia X1 and hope it's not as much HTC.

Read this: http://forum.xda-developers.com/showthread.php?t=335074
Hardware problem, repair needed and unavoidable to get 3G functionality back.
I have the same problem.
I bought an O2 Stellar (Kaiser) from a work colleague and it worked fine on 3G/Auto on the day I bought it.
The next morning, when I switched on the phone, it had exactly the symptoms described (i.e. it would only work if forced into GSM mode).
My colleague took it back to O2 under warranty.
1 week later, it was returned as 'fixed', but it actually still had the problem, so my colleague returned it again to O2.
Another week later, O2 provided a replacement unit under warranty.
The replacement worked fine, until the next morning when I turned on the phone and had to force it into GSM mode again because it wouldn't work in 3G/Auto mode.
I'm on 3 in the UK and I suspect the problem is something to do with the roaming onto Orange GSM which happens when there is no 3G signal from 3UK. However, on the day each of the units worked, it was switching between 3G and GSM repeatedly because the 3G signal is fairly poor in my office.
I'm now waiting for my colleague to return from his holiday so that he can return this unit to O2 and we'll see if we get another replacement. If we do, I'm very reluctant to actually use it - I think I'll probably just sell it on and get something different. Shame because I really like the Kaiser.
as mentioned before, another thing that you should've tried is to call the helpline and see if there's an outage in your area. I've been experiencing the same problem in a very particular area (3G hand-off to EDGE problem only happens on campus). Tried different radios and problem still exist, so I gave them a call today and turned out that there is an outage here.
In my case, it's not caused by a network outage - 3G works fine on my Hermes in the same locations.
Good thought though.
Relax boys...I have'd the same problem... The only solution is to go with your phone for warranty return. There they will change your TyTN II mother board and all will be ok. IT IS THE ONLY WAY.
PS do the same thing I did http://forum.xda-developers.com/showthread.php?t=418375
i post this thead and the solution
i post this tread an the solution came on tha answer of various of you great ideas i get the solution changing the rom and the wm to 6.1 and the rom is the dutty's it has worked almost perfectly in any wy itested only some install on the gps progrms but no mayor problem tks all you friens for a great support
The same thing has happened to me as well (Orange UK).
Initially I thought that it was an outage in my area as my friends had problems connecting to 3G as well, but their problem has been fixed but I still cannot.
I'll be contacting their tech support dept. later today and I'll post back.

[Q] Milestone is loosing signal - hardware or software error?

Yesterday my Milestone dropped the network and wrote "Only emergency calls". On other phones there was maximum signal. After a while the phone logged in to the network, but lost the signal again. I thought something is with the ROM, so I made a factory reset but didn't help. I flashed the correct SBF file (first Éclair, then Froyo), but didn't help. I restored an earlier MOD I used without any problem but didn't work.
I always used the German baseband files with other MODs because my Milestone is German.
The problem is that if I make anything (I mean anything related to the data connection), the GSM signal disappears, sometimes data connection remain with no problem, sometimes it is lost, too, but sometimes it has GSM signal with only EDGE network. If I do nothing, just turn off the screen and do nothing, everything goes back to normal, and the phone has normal data connection with GSM signal, I can make or receive phone calls.
I put in another SIM but the issue was the same.
Can I try something related to software and didn't try yet or this is a hardware failure? And if so, what is the price of a GSM module? I couldn't find it.
MOD: It seems that only the 3G is not working (sometimes HSPA does while 3G phone connection don't), with 2G there isn't any problem.
dial *#*#4636#*#*
Under phone info, try a different network type.
It probably defaults to GSM (auto). It does on mine anyway and it's fine.
But maybe WCDMA preferred, GSM only, or WCDMA only will work better.
It depends on which is screwing up... the WCDMA or the GSM
edit: had the dialpad code wrong... again.. geez

Are you sure you have applied the correct baseband?
I would tell to re-apply thru AOR.
Sent from my Milestone using XDA Premium App
You could go to settings, wireless and networks and somewhere there there is use only 2g networks and if that is checked, you could try to uncheck it. That is what happened to me before on the froyo mod. Also, you could try turning on airplane mode, then turn it off. Good luck
I always used the German baseband, tried to switch 2G/3G many times, applied the baseband trough OR, applied the RTEU baseband, re-flashed the ROM, the original Éclair, the Froyo, again and again but nothing helped. I gave up I decided to go to the service. Before that on a forum somebody asked something, I gave an answer but I was not 100% sure about it, so I flashed the RTEU Froyo.
And it worked. The 3G, HSPA, 2G, EDGE, phone functions all are working now. My phone is truly German, it has QWERTZ keyboard and the original ROM was the ROM from Deutsche Vodafone (tried that one before, too), it has the logo on its box, and the German baseband files always worked. I don't know what just happened, it's simply working now. Why now... don't know.

3G problem

Hello, this is my first post in this forum. Sorry if I have done anything wrong by posting here. Anyway the main thing is a problem I have on my Galaxy Mini S5570. After flashing a large number of custom roms like Emanonv5 and CyanogenMod 7.2 RC5.7, I came over the V6_Supercharger. During that time, I was on TheWhisps' AOKP rom. After installing everything possible from the V6_supercharger, suddenly I couldn't connect to 3G network. I can connect to the 2G network but not 3G. In fact, when I used *#*#4636*#*# and put WCDMA only, the signal bar on my phone showed that there was totally zero network coverage. I wiped data and reset-ted a bunch of times , flashing roms and many others, the problem couldn't be solved. Does anyone out there encounter this too? If you got a solution please reply. Thank you so freaking much
hav u tried putting phone on only wcdma.
smtymes in auto mode there is problem.

Chek if the 3G works in another mob. Coz dat doesnt seems to be issue with phone.. Try to do dat n if that doesnt. Make sure u install any stable roms n try n also make sure u emable only WCDMa as the abov post said. Change from auto to only WCDMA
Hit thanks if that helped u:thumbup:
Sent from my GT-S5570 using XDA
never had this problem with supercharger but asking the question in the supercharge thread will help alot
also check if only 2g is ticked
I have done the WCDMA only but the signal bar is empty. When I clicked Auto, the bar stays empty which I think that it can detect the 3G network but fails to connect. However when I put 2G only, the bar is full. The thing is, I encounter the problem both and stable and unstable roms. What I suspect and am afraid now is hardware failure Is it possible for software to cause hardware failure? Thanks alot

[Q] General Mobile Data Issue, Baseband Problem?

Hi at all.
This is my first Post, but i cant get any further with my Problem.
I used to have cm11 on my I9305 (T-Mobile Germany), everything worked fine (more or less).
Last Month from one day to another my Baseband completely disappeared without any obvious reason.
Luckily I had a Backup that worked with unofficial cm12 rom.
After that nearly everything worked.
Now, since 2 Days i got a new Problem. Everywhere where I got 4G, my Mobile Data work. But in Areas where I only got H+, 3G, Edge,
I have to switch my preferred connection to 2G, else my Data wont work. Sometimes for Seconds i see the 3G Logo, light up the Status Bar.
But I got no Connection.
The Strange Thing is, that when I call Someone, during the Call, the H+ Connection seems to work, but after the Call, it disappears.
And my WLAN Connection works only after every reboot (Connects, but no Internet, Also very disappointing)
Things I did yet:
-Flashed various Modems for I9305,
-Flashed different Roms (CM11, Nameless Rom, Resurrection Remix)
-Smashed the d*mn thing against the Wall :angel:
Information from my Phone:
-Baseband Version: I9305XXALK2
-Mobile Network Type: UMTS (it shows that, but no connection)
-Mobile Network State: Disconnected
-IP: Unavailable
Has anyone encountered a similar Issue, or a Solution?
Could it be a Hardware Problem?
EDIT: IMEI is okay. I try and try, but nothing seems to Work...

Signal/Data not working (possible hardware problem)

Hi, so my problem is that i keep losing mobile signal (3g and LTE). I put the SIMcard to another phone and everything works fine.
Did a factory reset and still nothing, i even installed Sony Stock Jelly Bean ROM and again nothing. When it's set in 2G it works ok.
The other thing is that i can't tell when the signal is lost because it actually shows that there is signal but when i want to call someone or use internet i can't. Could someone help please

Note: This reply won't be helpful
You might have an issue that is similar to mine. My XSP also shows signal, however, the difference of your issue with mine is that, I cannot receive any SMS, or calls. If I attempt to call someone, it somehow "triggers" network polling and then the signal resets to a correct one. After then I am able to receive calls.
However it is persistent, later in time it will "freeze" again.
I highly suspected that it was my XSP. Fortunately upon some closer look, the true culprit would be the radio tower (reception) at my home. At my university, the network works extremely fine. And if i return to my home, the same issue reappears.
I guess you should try going to somewhere else that is quite far from your home, and check if the issue persists.
If you are however having such issue constantly everywhere, it might also be plausible that a certain bands are out of service at your area
Well about the area service, my friends SG S4 is with the same mobile operator as i am and has no problems with the signal or mobile data. Any help on what to do ?
