Your digging around has misled you. The GT-I9505 has 2100MHz support for 3g, as noted here, here, and here. It also has 2100MHz support for LTE. So something else is causing your issue. Are you certain your phone isn't in fact getting an LTE signal instead of 3G?

So in my country all service providers work with 3g at 2100 frequency, why does my s4 doesn't connect to 3g?
Well... sadly after digging around i found out that the phone doesn't support 2100 frequency.
It's the official firmware for this country, was bought in this country but only gets 2g and 4g
any way to solve this mess? most of the data signal comes from 3g signal, if i'm inside of a building i only have gsm data :crying:

i flashed a new firware from sammobile
so... as i search for 3g, only show vodafone, not the network that i need, the phone is locked to NOS. Also should show MEO 3g, and doesn't.
Strephon Alkhalikoi impossible to make that mistake, inside any building with another s4 i get 3g fine
Inside the buildings there is no 4g cover, i really need the 3g
Based upon the information you've provided, you're on the Baltic Black Edition firmware (CSC SEB). The firmware here though doesn't appear to be the problem. The problem is that you need to clear up some confusion here. You're saying you can't get LTE, are using unbranded firmware, yet your phone is locked to a carrier.
In an attempt to clear up things, please provide us with the missing information below, and confirm any already provided information is correct.
1. Model Number

NOS (formerly PT Multimedia, ZON Multimedia and ZON Optimus). You will have to flash the latest firmware for your locked device. Download, unzip and flash this firmware via ODIN: HERE.
thanks but as i said before, i've tried many stock firmware, including that... that was te first one because i also thought that was something related to simlock
i will send the phone to warranty, or try at least
@Joku1981: If I didn't have to work today I would have told him the same thing.
@monteiro-ribas: If you intend on having the phone swapped out, you might want to flash the correct firmware that Joku1981 provided the link to before sending the phone in. I do hope you let us know if you get your issue resolved and whether it actually was the phone or, alternatively, the service.

My original post in modems:
Ok guys, my kingdom for a solution, please !!!
Here's the deal, I have a samsung galaxy S4 GT-I9505 bought in hong kong, worked flawlessly for over a year on Telcel Mexico network, took a trip overseas to France bought a sim put it in the phone, worked great !!!!, came home put in my original sim and since then my S4 has been unable to maintain a stable 3g connection, usually connects for a under a minute and reverts back to edge. I've tried many different things recommended on this and other forums:
1.- removing/replacing sim card
2.- removing/replacing battery for over 4 hrs
3.- tried different sim cards from different carriers with same result
4.- wipe and clean install with different firmwares
5.- installed cyanogenmod latest
6.- under network modes, tried selecting every combination of lte, 3g, 2g, automatic network registration and selecting my preferred network.
7.- tried flashing over 30 different modems
8.- flashed latest firmware from sammobile specific to my phone (I9505ZHUFNL1_I9505ZZHFNL1_TGY)
9.- took it to a "technician" and he managed to return my phone in the exact same condition with the exception that now the wifi didnt work (i managed to fix this on my own)
10.- installed advanced signal status from play store which gave acces to other goodies such as selecting radio band between automatic, europe and usa, tried everyone of them with no solution.
Tried to be as thorough as possible, hope someone out there has a solution. I thank you all for your time and experience. Happy Holidays !!!!! I hope I am posting in the correct area, i searched and found this is the place where my problem seems to be discussed
P.D. Since im flashing GPE right now the screenshots no longer reflect what im on but I do have a nandroid back up of this rom and I am about to restore it.
Hope I was thorough, thanks for any help

Downloaded SRS tool from another link which finally gave me access to Samsung Remote Unlock Client, followed the steps in the guide, used the file provided in this guide and everything seems to be working for now, gonna test for a couple of days and will update.
I have attached the files I successfully used. Great many thanks to the OP and to the 123unlock team, had this problem for over a month and fingers crossed this appears to have solved it. THANKS
it worked
Thank you all. This solved the no 3g problem on my i9505

Hello, i need the steps to. the link is broken.

Hi I'm looking desperately for help with these 2 major isssues, any advice will be much appreciated.
I recently bought this phone SM-N9005 and worked perfectly until I realized my gps doesn't work properly. After a brief research I discovered a youtube guide with positive responses so I gave it a shot. =hC8jNb38gaY . This included ServideMod digging via *#9090# -> insert Q -> insert 0000 -> UE settings -> setting -> system -> NV rebuild -> ALL . After that my sim card was no more functional just as any other I then tried. So this is my first major problem:
1) INVALID SIM CARD The sim card was doing just fine before that and is still doing when put into other devices, but no matter which sim card I try the problem still persists. So I tried factory resets, loading different firmwares... which led to problem:
2) CAN'T LOAD DIFFERENT FIRMWARE I think I was doing all accordingly to guides but still can't force my phone with different firmware. I got it rooted, and everytime I try to use Odin it just gets stuck at "Complete write" fail or FAIL Auth.
The only firmware I could load into it was the early leak of loli 5.0 N9005XXUGBNL8 . I then tried several of them so I could use for example AryaMod (which gets always stuck shortly after start of the installation - i think because i cant load demanded firmware) but to no avail. The so far tried firmwares were the stock ones;
N9005XXUGBOJ6_N9005XEOGBOJ1_N9005XXUGBOJ1_HOME.tar
N9005ZSUGOH3_N9005OZSGOH3_N9005ZSUGOH3_HOME.tar
N9005XXUGBOI6_N9005ETLGBOA2_N9005XXUGBOH1_HOME.tar
N9005XXUGBOI6_N9005O2CGBOF2_N9005XXUGBOH1_HOME.tar
And the only working is the one mentioned above from early loli 5.0 leak : BL_N9005XXUGBNL8_CL3643614_QB3415922_REV00_user_low_ship_MULTI_CERT.tar, which I currently have. Any other attempt to load meets with the same failure. I tried different versions of Odin, starting them as admin, different usb ports, wiping before, rooting it but just can't load any other. : /
So finally I'd like to ask: Is there any way to revert damages I did by doing that ServiceMod thingy? To get rid of that INVALID SIM CARD notice? I'd like to do it myself if possible.
And secondly, why can't I get any other firmware working? Is it wrong choice of firmware not compatibile with my phone or I just overlooked something during installation?
If you reached it all the way here, thank you. Please share any advices you might have.
Oh btw this is from *#1234# if its of any help : AP: N9005XXUGBNL8 CP: N900PVPUEOC5
What is the model number in download mode? Does the imei in the phone match the imei on the label under the battery?
Looks like wrong firmware flashed .
N900PVPUEOC5

...Well this is odd, the model number is everywhere stated as N9005 but in download mode it's N900P !
The mei number matches but it's short of one last number. The mei in back has 14 digits and in system 15.
Hey,
I got the same issue a few months ago,
It was the "pin" behind the cover that didn't reach for the antenna on the other side
This crappy video helped me a lot
https://www.youtube.com/watch?v=iUsXU28IDdM
Update: I just discovered I can only install the N900P firmware so right now the both AP and CP is N900PVPUEOK2.
But the firmware selection for 900P seems rather limited to USA region. Back then I had czech (maybe european version with czech language?) version.
Info about phone now says my phone is N900P even though my phone is 9005 and so was the firmware for it.
Hello everyone,
As this is my first thread, and I have been reading previous assists based on IMEI fixing and couldn't find the answer I am looking for, I really hope that the XDA community can help me fix my Galaxy S4 I9500. I will try to explain the problem the best I can, and I will create a list of every solution I have tried in the 3 week phone fixing saga I have.
1. The problem :
My friend decided he does not need this phone anymore, everything was fine with it except the battery was swollen(but I bought a new one so it doesn't matter). The day before he gave it to me, he accidentaly dropped it in the toilet and it couldn't boot. I opened the phone, cleaned it with alchohol and the phone booted up normally. The thing I noticed was that in the status bar the network symbol was replaced with No signal symbol. I tried 3 SIM cards and none worked. I decided to downgrade to 4.4.2 KitKat version and this is where everything went even worse. I used Odin to downgrade a firmware downloaded from sammobile.com, but I didn't create an /efs backup because I have flashed an Alcatel Idol 2 before and there were no problems with the IMEI or so. It turns out that Samsung devices are different and I am left with NO EFS BACKUP. I know, I should have checked what to do before flashing the device, but what's done is done. The device is doing everything great, there are no problems with Wi-Fi or Bluetooth either, except I cant connect to a network because IMEI is null/null and the Baseband is unknown. The thing is, I am not sure if the IMEI is wiped completely because of a hardware problem, or it's software related because of the /efs folder, because I am not a developer, but a civil engineer...
2. Solutions I've tried so far :
- Flashed many different Android versions;
- Flashed a Lollypop with adonis.pit with Re-partition checked on Odin;
- Tried writing an IMEI and repairing the EFS with Octoplus box;
- Tried flashing an EFS backup from my friend's Galaxy S4 I9500 ( IT IS ILLEGAL IN MANY COUNTRIES, NOT IN MINE, BUT I WANTED TO TRY AND CHANGE THE IMEI LATER SO IT WOULD NOT BE A PROBLEM );
- Tried flashing with a IMEI_null_fix.tar.md5 file which i found on a forum and that didn't fix it either;
- Tried KIES to return the stock ROM but either it does not recognize my device, or it says that my device could not be initialized or so;
- Took the phone to service, but in my town the only service we have is not very professional and they didn't even know the IMEI null does not mean that I will have no wireless connection/bluetooth connection, so they didn't fix it either;
- Tried with EFS Pro, Terminal Emulator and programs similar to those, 3rd party and PlayStore ones;
- Maybe other things but I could not remember because I think I tried everything...
I don't know if the problem can be fixed, but deep inside me I hope that there is a solution, and I think this is the best place to search for help, because it is a great phone and I don't want to throw it away just like that.
Thanks in advance everyone, hope you can come up with a solution.
Hi! I have an A5 (SM-A500FU) bought in Italy last year, Im using it since then in Argentina. With android lollipop I have never had issues with lost signal, no service messages or network not available. But since upgrading by OTA to Marshmallow these problems started. I have looked everywhere but I cant find anything that helps me. Also my service problems are not always present, sometimes I do have signal, but mostly when im out in the street. At home, for example I have no service and "only emergency calls" message. I'm using right now and old Moto XT316 with the same SIM card ( Claro AR) im using in the A5, and it is working fine, recieving network signal ( it is also a new sim card, just in case old SIM was the problem). The thing is I can´t use my A5 because it is constantly losing signal.
Thing I have already tried and didn't work:
- Changing to aireplan mode for a few minutes
-take out SIM card, restart the phone, turn off phone, put sim back in again, turn on phone
-verifiyng the APN for my network Claro Ar was correct, manually searching networks ( At home for example, it only finds Personal and Movistar (sometimes) but never finds Claro ar)
-Doing factory reset
-Reinstalling official firmware (PDA version : A500FUXXS1CPH2; CSC version : A500FUVFR1CPG2) with kies3 ( smart switch gave me an error)
-Flashing the UK BTU ROM ( the old one was from Vodafone Italy, now Phone info app says my mobile operator is 72234, while befor was 722310 which is correspondig with claro ar, what does this mean)
what could be causing this problem???? Im really starting to desperate now...
I read something interesting online, searching for some answers I got to the experience of some guy who had a very similar problem. Short story, his had to change his phone's network configuration in the "radioinfo" menu (or whatever the name of that hidden menu is) with an app named Network and force his cellphone to use only 3g or 2g. Turns out that his phone was trying to use LTE but LTE was not available in his region. This solved his problem. Mi phone can't use LTE here in Argentina because it is Italian, and since I have it it never conected to LTE network (I guess we use different frequencies) So I was thinking maybe my phone is also trying to use LTE but since it won't reach 4g signal ends up with no signal at all, excatly like this guy's phone.
But, apparently I need root access to get to this menu or even use this apps, is that correct?
So, should I root my phone to try that? does that story make any sense to you? Any advice?
Downgrade to lollipop I read is not my best option, also rooting it isn´t , but I'm starting to run out of solutions.
I add this information that could be helpfull:
Product Code : SM-A500FZKUBTU
Original CSC code : BTU
Active CSC code : BTU
PDA version : A500FUXXU1CPH3
CSC version : A500FUBTU1CPH1
Baseband version :A500FUXXU1CPH3
Android version : 6.0.1
Build number: MMB29.A500FUXXU1CPH3
Mobile operator :72234
Also IMEI number seems to be fine, it starts with 35 and matches the one in the back of the phone.
Sorry It is such a long thread!! Thank you very much!!
i recently got a note 4 N910H 6.0.1 for repair, the problem is that the phone connect and register on network only for some seconds and then it looses the connection and stay on this loop, what i have tried so far :
-Different ROM
-downgraided to 5.1.1, back to 6.0.1...
-Different Kernels
-Changed network mode :
* LTE/WCDMA/GSM(auto connect) : still on the loop (Connect, Disconnect)
* WCDMA/GSM (auto connect) : still on the loop
*WCDMA only : no loop and no network either
*GSM : no loop and no network either
-Mannualy selected a network : I can find all availble networks but i got error when trying to register on ...
-What i figured out : IMEI is not the same behind the battery and when i type *#06#
My customer said that the phone was working before and everything allright and that the phone was used when he buyed it
My guess is that the phone is blacklisted, but i want to be sure before givig feedbacks to customer , so anyone have an idea ?

I think this is not software issue.
Maybe radio antennas or sim slot is damaged.
I also bought a sprint note 4 n910p before and it was running n910f software and when i flash sprint official firmware my imei was changed. 1st when i bought imei was n910c but afrer i flash sprint imei was sprint galaxy S5..
Point is that my sim and signal was working fine even when imei was changed.
Go to note 4 exynos thread and flash n910c rom for n910h and see if it works.
