Hi All,
Got a GS4 i9505 originally locked to Vodafone, had to downgrade modem firmware to unlock to all networks - put in a Three sim - gives me signal but for emergency calls only - No data, no texts and no calls.
upgraded the modem firmware again - no change.
But a stock rom on - No change
Rooted and put a custom rom on - no change.
Tried a different sim (EE) and doesnt give any signal.
Everything now points to the IMEI being blocked right - Nope, checked that and its not blocked.
So im stuck, any ideas?
Thanks all
Where did you get the phone from? New or used? What firmware where you on and what are you on now?

OP, what country are you in?
The reason I ask is there is no such thing as three in Australia any more, it was closed down on the 31st august.

modem problems...
u need to visit Service Center :sly:
Send my E-960/S4 LTE/N2 GSM and /Galaxy Y to xda
Thanks for the replies.
The phone is second hand - apparently it was "unlocked" for 3 when i got it - even though it had a Vodafone bloatware rom on it.
Im from UK - :/ but thanks for the suggestion.
Its on 4.2.2 - stock rom - it was on a custom rom (not sure what though)
When you say Modem, do you mean the hardware or software?
If it is the modem, how would the 3 sim get signal but an EE sim wont?
Thanks
Hi guys,
My actual phone info:
Bought with JB Stock Vodafone from Spain
Imei unlocked
Updated over OTA to kitkat
rooted via CF auto root.
Knox tripped
Phone info:
XXUENA6
XXUENA2
VFGENA4
For a week, I looked all over XDA forums, read all threads but I still can't find a solution for my n9005 problem.
Here it is: I bought one in Spain, imei unlocked it to use it Morocco. Everything worked just fine and I could use gsm network with a sim from IAM (Moroccan Provider). I then set up mobile APN to have 3G, made sure my sim is 3g enabled, but the phone refused to pick up the 3g signal. I checked the phone's mobile network settings, and found that I haf only 2 options: gsm/wcdma automatic, and wcdma only options.
Well, since Maroc Telecom(IAM) isn't offering a 4G coverage yet, I think that's normal not to have the 4g option. Still, When I use the automatic option I only get 2g signal (and can read my mails over gprs,get twitter notifications, but no internet via browser, etc..).
When I choose Wcdma only option, I simply have no network signal at all.
When searching manually for networks, I get all 3 moroccan's providers but only their 2g networks.
I was prompted for the kitkat update via OTA, updated but it didn't solve the unavailable 3g problem(and caused a few others I managed to solve).
Now, I rooted my n9005 using cf auto root, and off course tripped knox, tried to reset the phone many times, but still no way to have a 3g signal.
Thought about installing a compatible Rom, but I am a newbie, coming from the Apple world, and need some help with this.
Actually, it amuses me that I really waited until android started to ressemble to IOS to decide to switch once for all to Android
Please guys, if you have any idea to help me get the 3G signal, that would be awsome.
Thank you in advance.

Just a quick feedback. This kernel didn't help. Same problem. Thanks for your suggestion.
hi...how did u solve your problem? any solution? i m having same problem with my n9005 bt no help...
hi, did you try flashing another baseband using odin?
Hi I have international version of S5 G900F. I flashed the phone with UK BTU stock rom. Now the problem is I cannot connect to the Network.
I tried going to Settings->More Networks -> Network Operators -> Select automatically . It took 5-10 mins to search but cannot connect.
Sim is not locked as it was working before I flashed the stock rom. also I read somewhere in internet that once the phone is region unlocked, it is permanently unlocked to use any other country sim. I don't know the original region of my phone but I bought it in Uk from 3rd party dealer not from any carrier.
I can think of two thing at the moment. It should be either regional locked again, but it does not prompt any thing to activate or enter pin or anything like that. or it should be wrong modem.
Is there a way to find if the phone is region locked ?
and is there a way to find correct region of the phone ?
the label on the box was removed so I cannot find from the box as well.
Thanks in advance.
I still haven't fixed this problem. Could someone suggest how to fix?
I've attached some screenshots with my phone info.
first image shows NETWORK:UNBLOCKED and IMEI Certi: PASS
-> I think this means, the phone is not blocked by network, and IMEI certificate has passed so it's not stolen or lost claimed phone.
another screenshot is the Firmware and CSC code/country information,
-> this means, this phone is build to sell in UK, so UK sim should unlock the regional lock.
Also the phone was working fine before I installed stock rom which I dowloaded from sammobile.
in the sceenshot, one of the network is connected but it says emergency call only because it cannot register to the network.
It is not sim lock also, because when I put T-mobile sim it does not ask for pin to unlock also.
what is wrong here. any idea guys? xda supposed to be the biggest android forum and samsung s5 is one of the most popular phone at the moment, isn't there anyone who have similar problem and solved? or atleast give some reason this cannot be fixed at all.
does the TMobile sim work? does it register with the network? If yes, then call the provider (of the other sim) and ask what's going on. Maybe you have a broken sim?

I've tried with Orange sim, and it still cannot register to the network. When I put the orange sim, it pop up a dialogbox asking to choose a network provider, there was two options, T-mobile and orange. So it is detecting the sim, but it cannot register.
And also, I tried my sim in another phone, and my sim works in another phone without any problem.
Did you try to flash the firmware again, and then after that restore factory defaults?

Yes I did, still it didn't work. I emailed samsung customer service with the problem, and they asked me to restore factory defaults.
I did that again but didn't work.
I tried one custom ROM as well. same problem in that rom.
You're rooted? If yes then there might be problem with the modem part of the ROM, can you install the official one part ROM and try with that?

I've installed stock rom several times, and several different versions( from here: http://www.sammobile.com/firmwares/1/?model=SM-G900F&pcode=0 ). Rooted several times, installed modem.bin files several times from many custom rom/ stock rom. None of them worked. I tried installing modem.bin when not rooted as well. And all the attempt failed.
I did everything I could possibly think of , Then I posted the question in the forum.
You have the IMEI ??!? Or it is lost?? Then only per efs-backup…
Or sim is broken…

I'm having the same problem, but with G900H. I have stock firmware, rooted and everything's working fine until suddenly, I have no network. I restart the phone and get network again but only for a couple of minutes.

Sry XanoZuke, I could not do anything to fix this, so I returned the phone and got another handset. I now have Exynos Octa-core version. Found snapdragon version is more power efficient. My phone gets heated very quickly.

Don't worry, I found out that the motherboard was water damaged (the irony of life....), so a bought an LG G3.
Regarding the Exynos chip, I'm never buying anything exynos ever again. The performance is not as solid as Snapdragon and it gets heated really fast. Still, thanks for your reply! ?

Sorry i end up selling the phone as is..
Same deal
My g900f has no mobile services sims fine
I have the same problem.
Cannot connect to network after flashing new ROM. Since then I tried about 10 different original roms and couple custom roms. Number of different MODEMs and BOOTLOADERs but with no joy. SIM card works fine in different phone.
Also I tried to load different CERT files and QCN with Z3X Box but that didn't help either.
I've tried *#0011# command here are results:
with LTE/WCDMA/GSM auto-connect:
imgur.com/i69HCBM
with WCDMA only:
imgur.com/QPbvKHG
and GSM only:
imgur.com/8InhQWQ
It seems that GSM is not working at all.
At this stage I run out of ideas and probably gonna get rid of the phone as it is or use it as pimped-out ipod touch
(sorry for messed up links but I can't post to outside sites yet)
I have a s4 i9505 that has a problem of weak signals or no service and gives not registered to network when trying to call. But sometimes its shows full signal bars especially when i am on the roof top and at that time i can even make calls.
The problem is with the phone not the sim because when using the same sim with other phones i don't have an network connection problems at same point where S4 shows no service.
So what do you guys think is it a Hardware failure or software problem.

Hi mate ,
Most of the times this is modem related if you were in a custom rom i would recommend to flash a new rom or even a different kernel , in you case i would reflash stock rom again to make sure is not software related
No it's not on a custom rom. Its on stock 4.4 Hong Kong version.

I have an i9515 black edition from the UAE but I'm using it in South Africa. When I first got the phone, 3G worked. After an OTA, it's stuck on 2G. I've factory reset a few times and even flashed a UK version of Lollipop on it. Still no luck. Is there any way I can get 3G/4G working on it again? Even if I have to root it.
Hello gc180,
please check you APN-Settings.
