hello ive just received a S4 ATT version which was sim locked so i unlocked it from a shop now the problem is the phone is rooted and its not getting any updates in Pakistan its on Stock OS 4.2.2 any way to update it OTA ?
2: with my current carrier its not working fine i calls dropping low signals around -79 to -91 DBM normally but if i put another carrier sim in it its signal strength is ok and if i put my sim in another phone on same place its also working fine so any ideas what could be the problem
3: when we go to Settings > More Networks and manual setup i receive list of operators which are available in my country so any way to find what their signal strenth or DBM is i mean any app is available or any way .

Regarding unlocked and rooted. You should know when a phone is rooted you can't get any OTA updates. If you want to upgrade you will need to do it via Odin from PC. In the general section there are a couple of threads pinned that will help.

Hi experts,
Very frustrated with the SGS phone GT-I9000 I bought a week ago. I keep getting "Data network not available" while trying to make merely voice call (in area with poor signal).
However, I have no problem making call using old Nokia phone with the same SIM card.
The GT-I9000 was upgraded to Froyo 2.2 (DXJPE) lately.
Anyone encountered similar issues? What's wrong with this Android phone, modem issue?
Regards,
Void
That new i would return to seller and get them to check phone under warranty .
jje
i got the same problem after upgrading to froyo, im from Panama, but i flashed my device following some UK guide, so i flashed it with another CSC, so if you did so, we both lose our network settings, so you have to set up the APN manually.(thats what i read) but i did so and i still cant make calls nor receive 3G
It happens on EDGE. Make sure you've selected the network to operate in WCDMA only..
Switch the Wireless and network -> Mobile network settings -> Network mode to "GSM only" or "WCMDA only" but doesn't resolve the issue.
However, I notice when the problem occurred, the Setting->About phone -> Network showing "Unknown" but the Signal strength seem to be OK, fluctuating between -87 dBm 13 asu (with 4-bar) and -111 dBm 1 asu (2-bar )
Probably, SGS transceiver/modem is not as good as Nokia E71.
Anyway, I guess I can only use this "smart" phone in city area.
in my case the problem was the orange phone card. i have changed it.
I seem to be having the strangest LTE / 4G signal issues with the S4. I get 4G fine but when i leave a 4G area it drops to H+ or if the signal on 4G is weak it drops to H / H+ during this transition i am left without any signal for seconds to minutes as it switches.
Is there any way to find out what my LTE modem version is as i know my GSM one?
I am not too sure if this switch is normal to be lost without signal as GSM > H > H+ works fine and i still have signal

Check your baseband version and try to flash through ODIN the right one for your location

how do i do this? i can only see GSM modem not LTE. i know both versions maybe different
Mate the baseband of your phone is the same for both the gsm and lte configurations of your phone. If that won't work you can still check your carriers vpn configurations to see if there are correct

i just searched forums :

**If you are having the old bootloader XXUB flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUBMH1.tar file with odin by selecting phone.
**If you are having the new bootloader XXUD flash GSM_Modem_XXUEMJ5_and_LTE_Modem_XXUEMJ5.tar file with odin by selecting phone.
So this means that even if it says the LTE modem is different to the GSM modem you are saying that the help about the modem for GSM and LTE is in fact the same?

From my knowledge you cant flash anything you like.You need to flash the correct modem for your region.Whats the version of your bootloader and your country so i can link you the correct file
I am experiencing the same thing, the switch from H+ to 4G doesn't drop the actual signal from the network whereas from 4G to H+ the signal drops leaving me no service at all for a few seconds.
I am starting to think that this is the normal behavior because it's like this since I got the S4. Oh and I have the latest modem for my country as well if that helps.
Perhaps someone with knowledge on how the modem works can chime in?

Thanks chickentuna for your reply
Ok the 4G works perfectly fine in Hong Kong, London but as soon as i leave london and go to areas with 4G but low signal, i get the horrible loss of network until the phone does a search. I think its more network / phone related but would just need to learn to disable 4G out of the main cities.
asbanoglou thanks for trying you can flash any modem but whether or not it will work is another matter. I understand bootloader, different modems and csc i am looking for something a little more non generic. I first assumed this was the firmware / modem combo but after trying multiple ones this does not seem to be the case unless there is a long standing issue with the S4 and LTE.
As a future note to get the modem versions you dial *#1234# . More > About does not give you the full picture but thanks for those who tried to help
Hello,
I have a huge problem with my Galaxy S5 SM-G900F. I bought it abroad and when I used it for the first time in my country I saw, that there is a problem with 4G/WCDMA connection. When I put my sim card to the phone and set all the preferences in mobile connection menu to "Auto" there is no possibility to call or to recieve calls (even if i saw signal strength meter showing some marks). I can only recieve and making call when I set "only 2G" option and manually select my network. But signal is also very poor.
What I have checked yet:
1. Other sim also doesn't work good.
2. After *#06# i saw my IMEI and it is the same under the battery and on the box (doesn't start from "00") so i think that it is not missed (efs folder).
3. Change firmware with KIES and ODIN for the other version - no changes. Also flash some other "modem" files with Odin with no success in better signal.
4. When im on the free air the signal strength is even at maximum level, but immidiately after going to my house - there is no signal. I saw also, that when im in the city i can connect with 2G network (only), but when im on a village there is no signal at all (even 2G...)
Do you have any ideas what can be wrong? Is this hardware failure? Maybe something with antenna? What should I do before going to gsm service center? Maybe i should change kernel and try some of the custom roms?
Thank you for your help.
regards
Mario

Maybe there is a region lock? Does the Imei start with 35xxxxxx? Does the S5 support the local 4G bands of your provider? Maybe ask your provider for a new simcard. Correct APN settings applied?
My IMEI starts with "35....". Samsung S5 should be able to connect with WCDMA/4G LTE bands in my country. My sim card was changed about 3 months ago, so it is good - i have checked it in nexus 5 and everything works very well. All APN settings are applied.
How can i check if the phone has region lock? The phone is from UK and now I live in Poland.

You can check on the box. If is has region lock, there will be a warning message printed on the box.
Is there any warning message in the notification bar?
And please check as below:
While the phone is receiving LTE/WCDMA signal, open the Dialer, enter *#0011# --> capture screenshot (1).
Then press Menu > Back entry (not Back key) > Menu > Key Input > Q0 > wait for some seconds... > MAIN MENU > DEBUG SCREEN > NAS INFORMATION > MM INFORMATION --> capture screenshot (2). And then Menu > Back entry MM REJECT CAUSE --> capture screenshot (3).
And post these 3 screenshots.
I was able to connect to wcdma signal (I think) for some minutes. I give you all screenshots.

Is your network Polkomtel?
The error cause is: No suitable cells in location area - This cause is sent to the phone if it requests location updating in a location area where the subscriber, by its subscription, is not allowed to operate, but when it should find another allowed location area in the same network.
So may need to give this information to your network operator and ask them to fix.
So it is not the phone problem? It is my network operator error?
My network is Play P4, but this provider has no transmitters for his own in Poland (or has very few). He is able to use all of transmitters in Poland through the roaming (so teoretically i can connect with Polkomtel, T-Mobile and orange transmitters)

Hi, este you able to fix your problem, ir so can you Please tell me how?
Hello everyone: I hope I'm not breaking any rules by posting this, but I'm having annoying problems with my handset since I updated the OS to Lollipop N900AUCUEOC1. My handset is SIM unlocked and use it here in my country Peru, South America. The problem is as follows, it is most of the time with only 3 signal bars of LTE, the handset must outside to get full bars, but the real problem is that sometimes it doesn't get any connection at all (pic attached), most of the time happens right after I disconnect from my house's WIFI, or sometimes, it only connects to H+(4G), I have to dial *#2263# and change it to any option and then, set it back to LTE/GSM to gain access to the LTE Signal, and I do this everytime I lose LTE signal, I must tell the phone to use LTE instead H+ o get the signal back. I think there is a set of numbers somewhere that I can manipulate and tell the phone that LTE signal is available always and stop losing signal. I little story to understand my predicament, when I bought it it I had the same problems, and I took it to a guy who did something to the handset and worked perfectly ever since, he told me he "recalibrated" the signal settings. But after upgrating it to Lollipop, the problems came back. And the guy is no longer where I remember I found him.
Thank you in advance for your help, I really appreciate it.:fingers-crossed:
If you have questions or need more info, I'll be happy to provide it.
Hello,
Try to enter in Settings -> Mobile Networks -> and choose the Prefered Network to the mode you want!
**You're not breaking any rules, you are just asking for help! XDA is exactly for that!**
(I'm using an unofficial and modified CM13 by TEMASEK, so this steps is in AOSP settings app, but I think that is almost the same thing in TouchWiz)
Try this and tell if it works! ^.^
Sorry about my english, I'm brazilian...
Hey, thanks for your reply, but I cannot do what you told me because I don't have that option, I'm running stock ROM and it is not rooted. I canot change the ROM to any other ca use of my locked bootloader . Don't worry, I'm peruvian, English is not my native tongue.
Images of my problem inside this word
Good morning, here are pictures what I have to go through to get the internet connection back on my handset. But today was the worst day of this issue, even this procedure did not work and I had to restart the handset in order to have internet connection.
Please, I need help!!!
Thank you in advance for your help.!!!
Check your modem/ baseband is the correct one for your country .

Take a look: HERE.
Whenever I switch to 3G only, my SIM Card signals go down and when I search for network operators, none of the operators are found. I'm living in Pakistan and my area is 3G/4G granted and my SIM Card is also 3G/4G but whenever I keep it to Auto, my signals come back and my phone runs 2G or E instead of 3G. It used to run 3G before but when I installed the latest firmware on my device using Odin, it never switches or finds 3G operators or network. I didn't remember the version of the old firmware installed. Can anyone help me?
I have searched the whole internet but none of the fixes are working.

What firmware did you flash in Odin? Was it the latest firmware for the g550t2 and for your country?
