3G connect and call problem - Galaxy S 4 Q&A, Help & Troubleshooting

I flashed russian version of 4.4.2 firmware from sammobile. I dont have root on my phone. But something wrong with signal status. Sometimes it loses connection to gsm operator and i cant make call but accept incoming calls. Sometimes after losing signal it doesnt come back so i need to restart my phone.
Ap: I9500XXUFNB3
CP: I9500XXUFNA6
CSC: I9500SERFNB3
i cut my sim card to make it microsim. Also i am from turkey. Do you think flashing Turkey firmware can solve this type of problems?

[Q] s4 i9505 modem question

HI2All. I want to ask if anyone knows where HSDPA+,3G , EDGE belongs when i`m downloading and installing modem in ODIN for I9505? Is it in LTE_MODEM or GSM_MODEM pack?
Because my country(Serbia) doesnt have LTE yet. My phone lose signal sometimes,especialy when transfering by itself H+ and E connection.
I Checked and i have old bootloader.
I`m using Omega v19 ROM (4,3)
*#1234# codes

Thanks
Should be GSM_MODEM if we follow the logic as LTE is the 4G and it runs separate from the GSM and GSM should stand for all those EDGE, HSDPA+ etc. Someone needs to confirm though.

Never mind if your country has or not LTE, your device is i9505, LTE allowed, so you must flash a i9505 modem (lte modem) even if you are not going to use lte. Gsm modem is for a different device (i9500).

[Q] 4G not working after 4.3 update

Hello everyone,
I have Galaxy S4 I9505 that is unbranded and unlocked, updated with the latest firmware via Kies3. Stock ROM, Knox 0x0.
My firmware info:
PDA: I9505XXUEMKF
CSC: I9505BTUEMK5
MODEM: I9505XXUEMKF
(I checked on sammobile and its UK BTU firmware)
I am from Croatia using T-mobile as a carrier. Problem first appeared right after the first 4.3 update was released via Kies3.
The problem is that when I select LTE in Network mode options it doesn't connect to 4G, the icon only shows H+ in a 4G area. If I leave it running in LTE mode, after a while the mobile data will shut down, signal will drop (like it resets) and after a few moments it will work again. My mail or whatsapp messages for example will arrive 10 - 30 min later. This will repeat over and over until I turn it off in Network mode and select WCDMA/GSM only. Everything was working fine prior 4.3 update.
Also I hope there is a solution that doesn't include flashing custom modem files or anything that voids my phone warranty.
Thank you,
Skyward

[Q] no LTE in Belgium with csc n9005phnena2 ap n9005xxuena6

Hello there.
I'm sorry if I haven't used the search engine right but I couldn't find a thread similar or answering my question.
I bought my phone, the note 3 in the Netherlands. It is an unbranded phone(phn) as far as I know.
But I am living in belgium. And for some reason I can't get my 4g to work with the Base operator.
Or with any other operators. For some reason there is no LTE option available in the network settings.
Now I have been searching on Google and went to some stores and compared my csc and ap version to the note 3 working on lte on the same network in the stores. And I saw with every note 3 in the stores that the ap version was ap n9005xxuena7 and mine is n9005xxuena6.
How come my unbranded phone with csc n9005phnena2 is not getting the update that let's me use 4g?
At least that is what I think?
After previewing the post, I noticed I have to update my signature. ..
Your carrier probably hasn't enabled it on your line.
Ring them up
Sent from my SM-N9005 using Tapatalk
I doubt that. They informed me about 4g them selves and the Sim they gave me had a small picture of 4g(lte) and 3 dual carrier on it.
Have you tried a factory reset?
I had a similar problem with my btu uk device after flashing the Polish na6 official firmware. Very unreliable mobile data connectity and went to 4g very rarely.
I didn't factory reset but instead flashed a custom rom (also based on na6) which fixed the problem completely.
I'd suggest factory reset first to see if that helps.

I don't know about Base, but with Proximus, you really have to call the customer service to ask them to activate the 4g for you. Did you try that?

I have a cheap abo with Proximus and have 4G on my note 3.
I don't have to do a thing about it so you don't have to call them its already activated for every abo.
I don't think it is operator related. Because my Sim works on my mother's s4 perfect.
I guess it is the update that is necessary to activate 4g on unbranded phones.

I can't say what's wrong with BASE, maybe they haven't enabled 4G towers yet...I'm on XL from Proximus and I get LTE all over Vlaanderen.
Well, try to flash some of the Polish 4.4.2 available all over XDA. My Note was also bought from Belsimpel but never had any issues with 4g--->with the latest NB3 (OTA) there's no more 4G sign...it's LTE.

Kies Backup works just fine...
Not every provider has 4G enabled in every CSC version. I get this question about 12 times a day on the T-Mobile NL forums.
I had 4G on DBT with T-Mobile NL two months before the T-Mobile NL Branded and PHN versions had it.
Resetting won't make a difference. This needs to be toggled in the firmware itself by Samsung. On most other devices you can use the *#*#4636#*#* or *#2263# dialer code to manually force the network mode, but they disabled it on the Note 3.

Thank you. You confirmed what I assumed was the problem.
I already have tried viaero. All I get is a black screen. No selectable option or toggle button. Nothing but a black screen. So I have to wait for an update or put a custom rom on it?
And is it possible to backup app settings? Like I dont have to configure Yatse again and Xbmc?
I am a noob with flashing custom roms and rooting.
Thank you.
call Base , tell them to activate it . Mobile Viking uses the base network and they had to phone base to activate G4 for my number.
up till few weeks a go you neded to make a call for proximus aswell but that changed because of the promoting of 4G action that is running for 6 months

No need to flash a customROM. If another official ROM has 4G enabled for our provider, you could flash that over PHN. No rooting, no knox triggering, no warranty issues. The only issue you might run into is that nonsense people have recently been getting flashing over PHN with the filesize.
NA6 is the most recent firmware for PHN. Could you go check in the stores what CSC version the devices are using that do have 4G on your provider? To my knowledge NA7 is a provider-specific version limited to T-Mobile and daughter-companies.

I have been searching on Google for people having the same problem. I found someone posting his csc version and for this guy is the 4g working with the Ota update he got.
His csc version was N9005OXXDMJ4.
I'm also going to the store tomorrow to look it up.

In theory, you shouldn't loose any data. You can always use Helium to make a backup. (KIES tends to hate the Note 3. Or life in general)

It can't make calls or send messages but it can access the internet.
That's happened after I click the system update in the setting menu. now the imei showing in the status bar is different from the one on the back.
Is it the reason? is there anything to do with the so called regional lock??

your mobile may flash with super with super imei, so while firmware update imei changed, did you purchased from authorised dealer in Hong Kong? Or threw online? If on line u may need to go mobile repair shop.

Its Region Locked to Hong Kong. That means it will only register on a network around Hong Kong territory. You will need to get a Region Unlock from Samsung to use it in Norway. On the side of the box it should have listed the countries your note 3 well work in. If norway was not listed then you can not register on any network in Norway. Contact Samsung
If u read op write about his phone imei number got changed after update, his phone may flashed with super imei for unlock region lock by seller.

Hi, i had been using this phone in Norway from January without any problem. The problem appeared only a couple days ago after I updated some features. And later I couldn't make calls but I can get access the 4g internet using facebook or hangout, and surfing internet. I purchaced a 4g data package from telenor.
the imei has changed since I flash the stock rom from sammobile. now still I cannot call but can surf the internet.

previous rom was 4.3, Hongkong. sorry I can't remember the exact info of the rom. I just left it not updated since I bought it in January.
The updates were some features, but not the system update. the version remained 4.3.
After the update I tried to flash a latest stock rom from sammobile to see if that would fix it, but still failed.

You should not flash modem randomly as it may brick your device.
As you device is HK version and the above modem is for N9005 International version, that modem is not fit for your device.
Didn't you have any IMEI backup?
If you don't have any IMEI backup, try to reflash the stock firmware for HK (not international one, as these versions have different PIT structures).
You cant just flash anything you find on Sammobile and expect for it to run perfectly. region locked or not. Because your phone was from Hong Kong you need to flash Hong Kong only firmwares nothing more nothing less. Flashing something not made for your region will change the IMEI. My friends did the same thing and his was also Hong Kong model. Tried everything to get it back but its pretty useless with out an EFS backup in hand.
Someone mentioned if you flash the original Firmware that came with the phone for the region it was made for it well bring your IMEI back. Give that a try. Give this a try.

I have HongKong N9005 32GB too..
I didn't know anything about different partition so I flashed 4.4 from UK. And Soft Bricked my phone.
Then I used PIT file for international version and All the roms worked but Unknown baseband and Null IMEI.
Then I flashed UK rom and then Flashed modem from my previous android version.
That means, 4.3 version modem on 4.4.2 and baseband came back.
Repairing baseband is the very first step in repairing IMEI and network problems.

- there is connection loss and problems with 3g/4g (h/h+).
