Galaxy S4 I9506 2g network problem

Hi,
I Have a galaxy i9506 (orange france android 4.3),
Phone was unlocked now but I have no network on 2G , 3G finds network just fine.
Any way to fix this? Can I rewrite modem file and then try to unlock with *#0011# method?
If this is posible can someone direct me to a good modem file?
Thank you.

If i write modem is posible to unlock by nck code i supose. I realy need 2g network.

How can I bring the phone to it's original state (locked orange france) so I can the use a NCK code to unlock it?

Flash the france orange firmware from sammobile's firmware database. Instructions are on the same page as the download. I can't link, sorry.

I did that , It kept all my programs and settings intact , root was left intact too. I used odin 3.09 . so nothing happedend after flashing original firmware from sammobile.

Complete Refresh

If you have rooted than its very good, wipe everything from recovery and flash complete firmware from odin. Its impossible that root is there, because system,kernel and recovery partitions are overwritten. However su binary app will be there but will not work because data partition remains intact.
Now back to your original problem, i don't know how you unlocked your phone? I am afraid phone's efs is not corrupted, because if everything is good means imei and modem and when phone try to register on network of locked phone then it simply ask code. Check imei, modem and network status, if your phone is registered on network and showing carrier name?
Backup efs partition before playing more because if efs is corrupted than you are finished ! I9506 is qualcomm version so QPST tool can also help in modem related issue, press thanks if it helps

Indeed after reflash i lost root. But the phone is still unlocked and no 2g signal. How can i relock it? The phone was unlocked with direct unlock option from some unlock software... dunno witch one(I bought it already unlocked and rooted )

I searched some gsm forums and found something that is said to work for I9506 too:
SPT BOX forum :
4.4.2 kitkat net probleme after supper imei unlock
connect your N9005 to the Box using USB in ( dm+modem+adb ) mode by dialing *#0808# in Samsung's Dialer ..
1st - Choose N900w8 from the list then click Repair 3G Network this will Fix the 2G network
2 - choose N9005 again and press repair 3G network again this will Fix the 3G network with 2G working too
Unfortunately I don't think anyone in my city has SPT BOX ( .... i will search some gsm services

Identify cause

I told u some points, please follow it and find out what is the root cause of your problem then try to ask or fix. You can use qualcomm nv tools and qpst for imei but first find out what is the cause then ask for help.
EFS professional also has nv tools and other fixes, use this download link

Hi , thank U for the info. I must now learn how to use the program to rebuild NV of the phone ( atleast i think that i must do) . never had to do such fixes of any phone. The i9506 was unlocked by direct unlock in z3x box. After that no more 2g connectivity , the phone finds network if I manualy search but cannot connect to it. Sais emergency calls only.
Anyway I think your sugestion will fix my problem .... just have to learn how to use program
Thanks again.

I rooted phone , backed up all that I could find to backup in EFS Professional 2.1.73 and after that I tried option "repair NV Data file permisions" "Option to repair NV data file ownership to fix 'Unknown baseband' and 'No signal' issues." .... then big dissapointment .... popup "This option cannot be used with your device! " . Damn I was realy hopeing that the option will repair my 2G signal problem. Seems that I must find another solution .... maybe some other sugestions?
Thank you.

When u run efs professional u have 4 options, try 2nd option 'Qualcomm nv tools' . Check information on diagnostic tab and if u see any thing wrong try secure ops tab for ESN / MEID / IMEI repair, also first check that your phone is showing correct IMEI by *#06# which is on behind the battery.

The phone is showing corect imei. I browsed through tabs , backed-up nvdata(took more than 30 min).I will look at diagnostics tab to see if anything shows "RED" .
Thank U.

I made some screenshots with the info shown in NV TOOLS . I don't know what to look for to see is not ok.

Plz post snaps of lockscreen, imei check window (*#06#) and phone about device. also tell me which firmware u have?

Screenshots , Firmware is Official 4.3 Orange France from Sammobile

From snaps, it seems your phone is registered on network and modem is working fine that's why showing correct IMEI. Normally when your phone is not registered on network, shows emergency call and null IMEI then you are unable to call or sms but i can't understand your case. If you are not able to call or sms then try changing different carrier sim or upgarde to latest kitkat 4.4.2, follow this link
http://samsung-updates.com/device/?id=GT-I9506
P.S. At last post snap of complete status window(in two snaps) from about device.

At last i can say your phone efs is corrupt, try manually writing IMEI again from Qualcomm nv tools and flashing kitkat 4.4.2. If don't work then samsung tool (Z3X) or other hardware box can fix efs like u unlock from Z3X box.
This is free tool which offer imei repair, ChimeraTool

[Q] service menue (+#0011#) Service : Limited ?

Hi,
I have this problem, after the mobile was rootet in a bad way. (Knox - 0x1)
1. My Note 3 -SM- N9005 has the problem -> IMEI 00/00
2. In the service menue (*#0011#) Line 13 IMEI CERTI : FAIL
3. in the service menue Line 11 Service: Limited
Well, the first and second problem I solved, but I still have no network.
I think Line 11 -> Service : Limited, is the problem.
Do anybody has a idea how can I fix this problem?

Your problem is IMEI 0/0 - most networks will not let a device with IMEI 0 join the network.
Your only hope that will not cost you is to try to restore a "golden backup" - also POSSIBLY present there inside service menu or if you have a backup of the partitions MODEMST1(12)/MODEMST2(13)/FSG(18).
Other than that you will need to contact a very competent shop (but as far as I know very few boxes can write back the IMEI on N9005) or Samsung directly.

=---------------------------------
The Imei I allready write back, its showing the right IMEI if I type *#06#.
Also my Imei certi is on PASS again.
But if I type *#0011# on line 11 shows -> Service: limited
Maybe thats why I don't have a net.

Does it show the same IMEI that is written under the battery? Since it is almost certain that somebody wrote you one of the 5 or so special IMEI numbers with certificates that have been circulating around with some boxes and which have been already blacklisted in most of the world.

Ok, the story is like that.
My son in law visit me here in Austria, and just befor he fly home again to the philippines, he buy him a Note 3 (SM-N9005) from here in Austria.
But he don't read the sticker on the box, " Europe Model" it has to be used with a europian SIM CARD before it can be used with a asian SIM.
So he just went to a mobile store in the Philippines and tell them to open the SIM lock.
After this the phone not work anymore right, it operate very slow. So finaly he send it back to me, by Fedex.
I take it to the "Mobile Store" here in Austria, but the told me the can't fix it becouse the " IMEI is lost 00/00" and in the Service menu ( *#0011#) it shows IMEI CERTI: FAIL.
So I bring it back home and try to fix it.
The Status now is:
1.) I write the IMEI back with this tool: EFS_Professional_2.1.73 ---> it works great my Imei is back
2.) I flash many moden.bin's until I'm sucsessful, and now my " IMEI Certi is : PASS
3.) If I try to use the phone, everything looks fine baseband is there the phone is fast, the only thing, if I try to use it as a phone, it say's " Not registerd to a Network" Emergency call only"
So I don't know waht the to in the Philippines, when the try to unlook it.
If I look in the Service Mode, it shows Service Limited.
Any Idea ?

[Q] stock 4.4.2. No service, data works fine

Dear all,
You are my last resort. I've been trying to find out how to fix the problem, but no success...
My Note3, 9005 (bought new, without contract), has never been rooted or modified in any way. Current version is 4.4.2. IMEI is fine. Well, I am a regular user, who keeps updating the phone, when there's an update from samsung OTA.
I've been using the phone for 1.5 year, everything was fine. I recently switched the operators (Belgium) maintaining the same phone number. And there the problems started.
Very often I get "no service" message, although data connection works fine. I tried automatic and manual selection of the network, but the problem remains. When I select automatic network, I get the message "registerred on network", but "no service" sign remains and get no call connection (data connection works fine). When I select the network manually, I get a brief message "registerred on network", but still no service and then "the network is unavailable"/
I contacted the operator, they claim that my account is fine, they see no problems on their systems. The interesting thing is, that other operators SIMs work fine with my Note. Apparently, it is only my current SIM which fails to work. I have two different phone numbers SIMs from this operator and they both have a frequent "no service" in my Note. I have also requested a new SIM, which again did not work... The same SIM works fine in Sony Xperia. I have also tried that same SIM in galaxy s3 (LTE). And there was again a problem with connection, i.e. no service, but data functions fine. I have also tried different modes (3G, 4G), the problems remain. It looks like it is the problem with samsung devices.
This is the time when I really need the phone for my work...I keep failing my clients because they cannot get hold of me. And changing the phone number and operator would be very inconvenient at this time.
Is there anything I could do to fix it?

try to flash stock firmware of your country via odin. i hope its work.

Nico, many thanks!
I understand my phone was brought from the UK. But currently I am in Belgium. Could you please tell me, what country firmware should I use, what specific firmware I have to flash? (I would appreciate if someone could refer me to a download link...I am not very good with these types of things, I am afraid to mess things even further...)

rooted, reinstalled stock 4.4.2. Now when making a call, the network dissapears and connection dissapears and becomes "no service", therefore the problem remains. data connection works fine.
guys, please advice, what can i do to fix it? should i go for other ROMs (not stock), would that help?
i've read about ariza patch, but did not understand whether it is available for note 3 4.4.2.

1. Install Kies 3 and conect your phone to the pc.
2. Take a look your CSC (pic attached)
3. Go to Sammobile.com and download the correct firmware (with correct CSC) for your device.
4. Flash this firmware through ODIN.
5. Enjoy :highfive:

Joku, thank you very much for your reply!
But I think I did exactly what you have recommended in the first attempt - flashed the stock version. Please see the pics of kies and suggested sammobile firmware attached. ...But "no service" problem remains. Althoug, I must say, it goes away from time to time (better than it was without reinstall). Maybe I should go for other country firmware (for example Belgium, where I am currently based and where the problems persist)???

All seems ok. Make a thing:
1. Backup your data and factory reset your phone (Pic attached)
2. Tell me if you have service then.

This is obviously a carrier issue as you stated yourself other carriers work fine. You can waste your time throwing things at the problem, but I'm highly confident it's not going to be fixed by anything you do.

It does sound like a provider problem...
Try a factory reset first, just to be sure. Best do it through recovery, so you can wipe the cache as well.
Does the no service happen everywhere? Or just in specific places?

Thank you all for your replies.
The problem is that the same 'no service' SIM works fine in another phone (sony xperia), the provider will claim that it is note3 fault.
I did factory reset after I reinstalled the stock version.
It looks like ' no service' appears when the phone changes the cell/network towers when travelling from one location to another. .. But I can't say that it is always the case. I just don't find any logical reason to fully explain that.
The weirdest thing is that data connection works fine always.

It is probably related to the way your provider does the 2G/3G/4G band allocation and switching - what provider is that?
You can also try to set the data to "3G only" vs "LTE/3G/auto" and see if is any difference.

The provider is Base (via virtual network provider).
I've tried everything, including changing to 4g, 3g, etc. Nothing helped : (
Should I try flashing different modems? The question is, which versions should I go for. ..?

updated to lollipop. no changes
I still haven't solved this issue. I just updated to lollipop (via CrashRom), the problem with "no service" remains.
Is there anyone with similar problems, who was able to find an answer? What else could I try? Should I try flashing different modems? Could anyone help me choosing which modems should I try?
pleeeease.... : )

anyone please?
can I try flashing different (older) modems? would that mess up my curent rom?

Check this post for downgrading from Lollipop to KitKat.
Regarding to "No service" problem, go to the ServiceMode MAIN MENU and try NV REBUILD.
To open the ServiceMode MAIN MENU:
- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#27663368378# > 'Launch 0'.
- If you don't have root, open the dialer > *#0011# > Menu - Back > Menu - Key Input > Q0 > wait... until it appears

iritoi said:
firstly, many thanks for your advice to rebuild nv.
i did as you explained, but... it did not help.
i went through all of the options available, flashed stock firmware, flashed various roms. nothing helps. what's interesting that i have call availability (service) for some time, but when i move to different area, the service dissapears and i have to turn on/off airplane mode. and this happens with specifically one provider (mobile vikings/base - belgium). if i insert the other provider sim, note 3 works fine.
my imei is ok.
pleeease help me to fix this problem. what else can i do? is theo nly option left to change provider?

Currently I have no idea.
Your best bet is flashing back to original stock firmware.
And try to check your SIM card in your Note 3 by follow these steps:
In the ServiceMode MAIN MENU, select DEBUG SCREEN > SIM INFORMATION, you will see 3 options. Select every option, capture screenshots and post it here more more checking.

In the band frequency it says "unexpected value". Maybe that has something to do with the problem... Or am I being listened by secret services : )

Mine are the same.
Except for the 1st screen: SIM Phase = 2; SIM voltage class = 3V.
The 2nd and 3rd screens are the sme.

is there a way to see the reason why the network is being disconnected via service menu?
...because when i turn airplane on/off, the network comes back. but when i dial the number it disappears right away with the message "network not available".

Yes there is. Here is how:
- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#197328640# > 'Launch 0' > BASIC INFORMATION (capture screenshot #1) > Menu - Back > NAS INFORMATION > MM INFORMATION (capture screenshot #2) > Menu - Back > MM REJECT CAUSE (capture screenshot #3).
- If you don't have root, open the dialer > *#0011# (capture screenshot #1) > Menu - Back > Menu - Key Input > Q0 > wait... > DEBUG SCREEN > NAS INFORMATION > MM INFORMATION (capture screenshot #2) > Menu - Back > MM REJECT CAUSE (capture screenshot #3).
And post these 3 screenshots for more investigation.

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:

so.... I9505XXUGNJ8/
csc I9505YXXGNK1
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
Answer: GT-I9505, based upon the title of the thread.
2. Android Version, found by going to Settings > More > About device.
Answer: 4.4.2, based upon the firmware information.
3. Firmware Version (AP, CP, CSC), found by dialing *#1234# in the dialer or by installing and running Phone Info from the Play Store.
Answer: AP and CP I9505XXUGNJ8, CSC I9505YXXGNK1, which using the sammobile.com firmware checker links to the Baltic Black Edition firmware.
4. Service Provider
5. Country
6. Is the phone rooted? (Yes/No)
7. Is a custom ROM installed? (Yes/No, and the name of the ROM)
Answer: No, if you're able to pull up the firmware version via *#1234#.

You seem extremely knowledgable on this subject, would you mind if i picked your brain ???? Ive been having a similar problem:

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.

No service, emergency calls only after upgrading to android 6.0.1 by OTA

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!!
