Installed res remix two days ago it was working fine network coverage seemed fine... then I woke up and I had emergency calls only no signal... Tried re-flashing didn't help. Tried a stock rom and it still didn't work.. simcard works fine in friends phone, and a simcard on the network Three works fine in my phone :/ so i'm abit lost at what to do, I'm pretty new to all of this so please ignore my stupidity lol
I think it has something to do with the baseband or modem

i've tried different modems and the phone works on a different network sim would that still cause it
Search the thread for a modem of your region and try a few till you get one to your liking. Takes a while for the phone to get 'used' to a new modem so even if it isn't the best at first, the signal tends to improve after about a day or so. I have never encountered problems with signal but I hope this helps

I've recently noticed a weird network bug on LFB. If the phone loses signal (on subway etc.) with data on, when signal is available it acts as though the SIM was refused by the network continuing to display Emergency calls only. If I turn data on and off it gets weirder (see screenshot).
The only way to fix it is too reset the radio, with flight mode, or *#*#4636#*#*
It's definitely not a hardware fault since, as you can see it still can connect to the network. It just acts as though the connection was refused (or alternatively does something weird that causes it to ACTUALLY be refused)
Anyone else experienced this??
The phone is an original BTU using unmodified LFB on China Unicom

Are you able to set/receive calls or send/receive SMS? What about USSD codes to your provider?
I've already read about other users complaining about this issue, I guess it's a software-bug in the display.
No. I'm not sure if HSDPA will work in the example pictured. I was in a hurry to make a phone call so just quickly snapped the screenshot then reset the modem.
Messages will get service unavailable. Incoming ones don't get received until I reset

Yes, I've experienced the same thing a couple of times since LFB on carrier Telia in Sweden.
It reminds me of the phone/modem problems with the SGN which they never fixed before I sold it.

Beijing.
Well 2G is okay. But it sometimes will lose it briefly in the transition from 2g to 3g.
Only Beijing subway line 4 has China unicom WCDMA coverage. the others are limited to 2g at best (except the overground lines, but even they are patchy)

Having updated to the stock LFB ROM and modem (UK, unlocked, unrooted), I'm really perplexed about the behavior of the phone data reception:
(a) 2 weeks ago, I tried using data connection in a friend's flat in Balham (London), could not get ANY data connection all weekend.
(b) Last weekend, data was consistently perfect and fast anywhere in the same flat, all "H+" 8Mbit and lovely.
(c) This weekend, same place but NO reception again, not a saussage. Voice phone worked fine, just no data at all.
And, yes, I've seen "emergency calls only" sometimes even when there is apparently a strong signal.
Back home again (Portsmouth), phone works fine.
On the plus side, battery consumption is wonderfully low!
Can anyone explain what's going on? It feels like the data connection is sometimes reluctant to "log in" or whatever is does! It seems to have a mind of it's own.
Thanks!
You may want to try another modem like DXLF3. It has better data network stability especially in cities or areas with faint signal.
I am planning to upgrade to the LFB, but i am not rooted. Want to be sure if i have problems with the modem signal, do i have to be rooted to install the new modem driver??
Thanks in advance...

I purchased a galaxy s3 international version about a month ago. The phone was working fine for about a month until yesterday, my phone is getting very little or no signal at all. also, when i connect my phone to my car, the phone will start calling itself. i performed a factory reset and the bluetooth problem was gone, but the phone is still getting very little to no signal. wifi is working fine. i called Rogers, my service provider. all they ask me to do was to buy a new sim card or remove the battery from the phone and wait. none of those helped... :crying: i'm kind of desperate here as i can't figure out what went wrong with it... my phone is not rooted or anything... if someone can help me out, i would really really appreciate it. :crying::crying:
Unless you are willing to start flashing modems to your phone there isn't much we can do for you.
Best bet is to keep pestering your carrier if you don't wanna root and modify your phone.

thx for the quick reply. So rooting my phone and flash a new rom is the only solution? :crying: is it possible it's hardware problem?
Not a Rom, not before trying modems anyway.
It may be hardware related, you should keep pestering your carrier for a replacement.
If it world fine before then chances are its a hardware issue or the cell tower near you is down.

Is the phone new? Has it ever worked for you? Have you considered the fact that it could be network locked(SIM locked)?
My phone ALWAYS shows "Not registered on Network" when I'm at home, that's because signal is terrible since I updated to JB (modem related).
Have you tried different SIMs from different networks? Have you tried your current SIM in a different phone?
[the phone is from 29 june..always worked bit one day data stopped working.. i got a HTC sensation and the SIM works fine in that phone/SIZE]

"What did you do between it working, and it no longer working?"
You say data doesn't work, does that mean you can make phone calls?
I didnt do anything it just stopped working and i cant do phone calls...its like using an iPod.. maybe someone blocked my imei?could it be possible?

Yes, it's entirely possible, but you'll need to check with your provider. There is no way of checking from the device itself if the IMEI has been blocked.
Did you buy the phone new?
You could, potentially, be extremely unlucky and someone blocked the wrong IMEI code when attempting to block their own.
Ye it was new..there is no way to make it work then?

Well, if it really has been blocked, you should get in touch with your provider, and potentially have to go through some lengthy process of proving to them you legitimately own the device and didn't block it yourself. It's unlikely though, as I've never heard of a device being removed from the block list before.
Your other option is to leave the country, it will work in another country
Failing that, return it to Samsung telling them it just stopping working, you did nothing, and insist they replace it.

Hi all,
I tried some of the available 4.3 and 4.4 rom but I got a huge problem is that I lost my mobile network connection after some time and sometimes even rebooting does not fix it. Sometimes when I do a call I immediately lost the connection and after 10 sec it is back and switching to 3G it let me do the call.
What can be the cause of that?

My network simply no more working and in Quick Panel I can see No Service/Emtel (Emtel is my network provider) but I can't do nothing sometime rebooting do the trick but sometime I need to power off the phone and let it charge for about 30 min and power on and then it is back to ok. The weird thing is that it does not happened everytime sometime my battery can do to 1% and still having connection fully.
When I got that problem I noticed that my phone is heater and sometime lag.
What can be the cause of that? I'm on Stock right now without root I will tried it but the problem does not happened everytime sometime I can get it after 1 week or sometimes after 3 weeks or more.
Please help me as I would like to have 4.4.2 on my phone.
Thanks in advance for your help
Can someone help please?
Service maybe due to provider or signal tower near by. How old is you're current battery? Signal drops once in a while are very hard to solve. Things to try are modems and other network's.. That's about it. But if it only happens once in a while it's not to much to worry about and most if not all Android phones need a reboot once In a while too.

Thanks for your reply, I tried to reinstall 4.4.2 from Neat ROM and I found that the problem occur everytime my battery is below 20% and only charging it back to a higher level fix the problem of my network loss. What can be the cause?
Thanks in advance for your help.
Does it shut of signal at 20% every time? Have you installed any mod to do this to you're signal? It could be a faulty battery messing with you're signal. Battery is the first thing I would check .

The fact is that I don't understand the battery. It does not happened ever time below 20% sometimes I can use it till 1% and it is working fine and sometimes no. I don't understand the battery as when I have this problem I can power off my phone and put on charge and while charging it indicated sometimes 40%, 60% etc... as on it is saying only less than 20% you think it is the battery?
One more thing this only happened when I have data connection on but if I disable data then it work fine.
