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... 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)

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

RESOLVED: Enabling LTE on Samsung Galaxy Note 3 (model: SM-N900W8)

Have a Samsung Galaxy Note 3 (model: SM-N900W8) and wish to enable LTE for a specific carrier? Follow these in-depth instructions and you will enable LTE for this specific model. My Samsung Galaxy Note 3 model is from WIND Mobile and I use both WIND Mobile and Telus SIMS on the device (interchange when needed). When using WIND, I get their default 4G data speeds and with Telus, I now have LTE which is like going from a Honda to a Corvette.
These instructions will work with all the SM-N900W8 models but you will need to select the appropriate root for your country/carrier (as indicated in Chainfire's post).
Should you have any questions, please respond to the post or send me a PM and I will assist where possible.
Thank you to the following 3 individuals! Some assisted with their general posts while others provided informative information via PM to ease me into the process:
AllGamer
Chainfire
asaqwert
UNLOCKING YOUR DEVICE
Before you are able to use another carrier SIM in your device, you must first unlock the device. I know there is a method of doing this for free after rooting but I paid $32.99 USD and received my unlock code through cellunlocker.net. If unlocking to use a SIM from another country, make sure you first activate with the original SIM. Failure to do so will region lock the device so you cannot use it with an International SIM. The only way around this is to pay a Samsung technician to reset the device. Since I use WIND and Telus, both carriers are Canadian so I went ahead and unlocked my device using the Telus SIM directly as I do not need to worry about a regional lock.
ROOTING THE DEVICE
1) Download and install Kies (for the Drivers) from here http://www.samsung.com/ca/support/model/SM-N900WZKEBWA
2) Download the ODIN software and ROOT provided by Chainfire:
http://forum.xda-developers.com/showpost.php?p=46098951&postcount=3
3) Unzip the files just downloaded and run the ODIN software. Once loaded, click on the PDA button and browse to the ROM file:
CF-Auto-Root-hltecan-hlteub-smn900w8.tar.md5 (this was the file I selected for my Canadian provider as my device is WIND Mobile). Make sure the check-box in the ODIN software that says "Re-Partition" is either unchecked or greyed out.
4) Power off your device and once off, reboot into the Android system by pressing Volume Down + Home Button + Power (all at once). When you see the Galaxy Note 3 logo, let go and it will present you with a warning regarding installation of customized OS's. Click on the volume up button and this will allow you to continue and present you with a Android logo screen and the word "Downloading".
5) Plug your device into the USB port and click on the "Start" button within the ODIN software. It should take a couple of minutes but the status window in ODIN should say successful.
CONGRATULATIONS... You have now rooted your device!
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
INSTALLING TWRP (TEAM WIN RECOVERY PROJECT)
I loaded the above program which I recommend you do as well. TWRP is a fully touch base recovery software program that allows you to store/backup and save custom ROMS either to your computer or to the device itself through internal storage or external SD. Think of it as a simple way to manage your device rather than having to enter a bunch of codes or press key sequences to get into specific low level menus of your device.
The software can be downloaded from the following link. I downloaded the latest 2.6.3.4 version:
http://goo.im/devs/OpenRecovery/hltecan
1) Power off your device and once off, reboot into the Android system by pressing Volume Down + Home Button + Power (all at once). When you see the Galaxy Note 3 logo, let go and it will present you with a warning regarding installation of customized OS's. Click on the volume up button and this will allow you to continue and present you with a Android logo screen and the word "Downloading".
2) Load the ODIN software, click the PDA button and select the TWRP package you just downloaded:
openrecovery-twrp-2.6.3.4-RC1-hltecan.img
3) Plug your device into the USB port and click on the "Start" button within the ODIN software. It should take a couple of minutes but the status window in ODIN should say successful.
CONGRATULATIONS... You have just installed the TWRP software which will open your device up to a world of possibilities.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
INSTALLING AN LTE CAPABLE ROM/MODEM
Now that you have your device rooted and the TWRP software installed, we now want to enable the LTE capability so you can use this device at the best speeds possible! Unlike what many have posted, I confirmed with AllGamer you can load any carrier SM-N900W8 ROM onto the device as long as the models version match (ie: SM-N900W8). My device is WIND Mobile and this carrier does not support LTE so the fastest speed I can select is 4G which is WCDMA/GSM in the network mode settings. Since I will be using the device on Telus with LTE data speeds, I want to install this ROM but ensure the device will have LTE as a option which I can select under network mode.
1) Go to the following link and download the carrier specific ROM for the provider you wish to use your phone with (in my case, Telus):
http://www.samsungis.com/Firmwares/SM-N900W8.html
2) This is a large file so I downloaded it to my Pcloud account then onto my computer which took about 30 minutes. Once the file is on your computer, extract the contents.
3) Power off your device and once off, reboot into the Android system by pressing Volume Down + Home Button + Power (all at once). When you see the Galaxy Note 3 logo, let go and it will present you with a warning regarding installation of customized OS's. Click on the volume up button and this will allow you to continue and present you with a Android logo screen and the word "Downloading".
4) Load the ODIN software, click the PDA button and select the ROM package you just downloaded (in my case, Telus):
N900W8VLUBMJ1_N900W8OYABMJ1_N900W8VLUBMJ1_HOME.tar.md5
5) Plug your device into the USB port and click on the "Start" button within the ODIN software. It should take around 5 minutes but the status window in ODIN should say successful.
6) Your device will now reboot and you will need to go through the setup process. Once complete, you think LTE will be enabled but you are wrong! You must dial the following key sequence to bring up a regional carrier menu: *#272*[IMEI]# (that is *#272* (your IMEI number) #) - To find your IMEI number, check your manufacturer box or press *#06# from your call menu and it's the first 15 - digits.
When the menu pops up, it will show a listing of codes and it matches the "region" list that's shown at the following link: http://www.samsungis.com/Firmwares/SM-N900W8.html
When the menu comes up, select the regional code for the carrier ROM you just installed (in my case, Telus which was "TLS"). The phone will now go through a reset/boot sequence and come this time, it should read the APN settings from your SIM card and viola, you now have LTE. If you do not see LTE but 3G, you will need to ensure your APN settings are correct and then go into the Network Mode and ensure you have LTE/WCDMA/GSM (auto mode) selected.
CONGRATULATIONS... You now have rooted your device, installed a custom ROM for the carrier you wish to use LTE on and have LTE capability. Since you have installed a specific ROM and set the regional carrier settings to this ROM, if you look under your status menu, instead of it saying "Custom" next to "Device Status", it will show "Original".
I hope this information helps others who have been stuck with enabling LTE on their device. Remember, LTE will only work for carriers who support LTE capability. Should I switch my SIM card and put my WIND SIM back into the device, it will work but the MAX data speed I will get is 4G.
Good luck everyone and again, please thank the above 3 individuals for the countless amount of times they have helped us members out with our problems!
Great post!
seems like the most important part was step #6
that was the missing info to complete the LTE setup.

Thanks! Look at everything that can be accomplished with a little hard work, dedication and assistance from those in the know. I only wish I was able to figure this out sooner without bricking a device. A costly mistake but a learning experience so all in all, no complaints!
will this work for the N9005 model?? I currently have
AP: N9005XXUBMJ1
CP:N9005XXUBMJ1
CSC: N9005OLBBMI3
Im using T-mobile right now, and would like to know if its possible to get the LTE for T-mobile in the US.
Thank you
So let's say I have a Mobilicity N3, and use this method to install the Bell ROM. Does this mean I now have a "Bell" N3? Will the OTA updates still work? Will this cause any known issues? If I factory reset the phone, it will be reset as a Bell N3?
Theoretically, installing any of the Big 3 (Robellus) ROMs should do the trick from an LTE perspective, assuming you've SIM-unlocked the phone, yes?

Hi, i have an N900W8 Rogers Note 3. I have a T-Mobile rom flashed on the phone., however, my baseband is still MJ1 (Same as my Rogers stock rom). And im having Poor LTE reception. Can you provide a CWM flash-able zip modem i can flash that might fix this issue? Or can i download the stock rom myself and flash ONLY the Modem? Thanks!

I suggest to do verifications before you flash a modem. Call Rogers and ask tell to do a "resend to switch". Call from an other phone if u can and listen to instructions
Also, update the phone to the latest firmware to have the latest modem.
Info: you can flash kitkat although the approved version by Rogers itself is not out yet.

Hi, i am with Fido. The Note 3 is from Rogers though (Same company). I dont want to flash the entire stock rom is the reason im asking for only the modem. I was wrong before, currently im using an N9005 Note 3 rom called Hawkish Elite. And the rom i was on prior to this one was the T-Mobile Note 3 based Darthstalker rom. I really dont want to have to flash the stock rom. So any information would be greatly appreciated. Thanks!

Rogers LTE issue
hello all,
I was wondering if someone could guide me in the right direction as i need help enabling LTE on my phone on the rogers network.
I came across a thread about enabling LTE on the SM-N900W8 model of the samsung galaxy note 3 (the one i have)
I do not have LTE showing up on my phone, i tried speed test and the best i get is 4G with 9mb download speeds.
I actually sent my phone in to repair and the gentleman swapped out the motherboard to change the IMEI legally.
Its an unlocked phone at this point and it has model number SM-N900W8, ive gone into the settings and selected LTE coverage but it doesnt give me more than 4G.
getting back to the instructions on the thread, i had a couple of questions.
If my phone is already rooted to another version can i follow the step by step instructions and "re-root" over the existing root which is the second instruction after unlocking the phone itself in this thread. Will it "brick my phone?"
on The third set of instructions for installing an LTE capable ROM/Modem i dont see any rogers options when i click on the link...can i load a Bell one as currently i think my phone had a bell one installed onto it as it had Bell TV bloatware etc when i got it back from the motherboard swap out. IT IS an original Rogers phone.
your guidance on this matter is greatly appreciated, i was so happy to search and find a thread helping with my needs!
First post!
I have a Fido firmware on my device (country code FMC)... and I'm using it with Virgin Mobile. Do I really need to do all those steps if connecting to LTE is not really a problem right now? I did not do a speed for now because LTE coverage is nearly non existent where I am... but I see it connecting to LTE.
If I do all the steps to change the ROM and CSC, will it format/reset my device?

Also for those unaware you can force LTE only by typing in *#2263# and Selecting LTE Band Pref -> LTE ALL
Please note you will be unable to receive a voice call as (in Canada at least) calls are still handled on the UMTS/HSPA network as no carrier I'm aware of has VoLTE yet.
...and if one switches over to LTE only, can that same phone be put back without issue? any tested?

Also for those unaware you can force LTE only by typing in *#2263# and Selecting LTE Band Pref -> LTE ALL
Please note you will be unable to receive a voice call as (in Canada at least) calls are still handled on the UMTS/HSPA network as no carrier I'm aware of has VoLTE yet.

You mean if I activate lte this way I won't be able to make calls? Do I have to disable enable lte everytime I need lte?
Sent from my SM-N900W8 using XDA Free mobile app
This worked for me. I now have LTE on AT&T.
Thanks!

Hi,
The first thing would be to check your CSC and modem firmware. Use Phone INFO ★Samsung★ app to get all major info about the phone. It is important to know when you are going to flash another stock firmware.
I had issues last week with data and it was caused by bad CSC/modem. Flashed everything back to stock with official firmwares from SamMobile and it fixed my issues. After that, I was able to flash my custom ROM and everything is smooth sailing since then.
Let me know if you require more help.

Thanks for help bro. I took a screen shot of my info. I'm not sure why it shows bmc when I downloaded the rwc files. And is the product code correct?, also I never seen the code for csc modem before. Is it not suppose to match baseband, pda, bootloader
Everything is good, you're almost there.
You have the right firmware but now you need to fix your CSC. The stock ROM is multi CSC so Rogers (RWC) is already installed but it chooses Bell (BMC) by default. What you can try :
- Power off your phone
- Remove SIM card and power on (your phone will start and say : no sim card)
- Power off and wait a moment
- Insert your Rogers SIM card and power on your phone in Recovery Mode (Volume Up, Home and Power on boot). If you have:
#manual mode#
--appling multi-csc...
applied the csc code : RWC
successfully applied multi-csc
That means that your CSC has been changed to Rogers. Problem should be fixed.
If not, the app you downloaded contains a CSC Changer but it will wipe your data. Make sure to have backups beforehand.
Let me know if you need anything else.

Thanks for all the help man, did the sim thing and it just loaded me into twrp and i didnt see an option so I changed it via the app. Same thing still got the 4G and bell bloat. But csc now says bmc/rwc
Ok. Try this now :
You must dial the following key sequence to bring up a regional carrier menu: *#272*[IMEI]# (that is *#272* (your IMEI number) #) - You'll find your IMEI in the Phone Info app.
When the menu comes up, select the regional code for Rogers RWC. The phone will now go through a reset/boot sequence and come this time, it should read the APN settings from your SIM card and viola, you now have LTE. If you do not see LTE but 3G, you will need to ensure your APN settings are correct and then go into the Network Mode and ensure you have LTE/WCDMA/GSM (auto mode) selected.
Let me know how it goes.

I actually did the last sstep you mentioned below this morning (found the steps online ) and it still didn't work lol, so technically when i did it in the app it was my second time restarting the phone.Not sure what's going wrong here. Seems like bmc still lingers around. Haha don't give up on me

Don't worry, I'm not giving up on you
When you flashed back to stock ROM, did you do a full wipe before?
It is really important that you do a full wipe so that it doesn't leave any traces of your old installs.
Try to flash via Odin (while your phone is on Download Mode). Check the AP and the CSC box and input the stock file from SamMobile.
Let me know if it fixes it.

[Q] S4 Problem with network WCDMA (3g)

Hi all, I have a problem with 3g.
I bought s4 i9505 and it was on 4.2, I had problem with slow internet, so I called operator and they told me to turn on WCDMA only in settings..
When i turn WCDMA only on, it loose my network (emergency calls only), and i have no network at all.. when i put wcdma/gsm automaticly it has normal network..
So i thought its problem in firmware, so today i fleshed 4.4.2 with odin.
Now i have same problem, no network with wcdma only..
I serached internet and i tried several programs for 3g, but nothing worked.. any solution ? thx
did you try another simcard?

Some problems can appears:
1. Type *#1234# and paste here what appears. Continue with the step 2 if you have wrong CSC.
2. Wrong CSC. Solution: Install Kies 3 for know ur CSC (pic 1). Go to Sammobile.com and download the correct firmware 4.4.2 (correct region) for your device.
3. Flash again this firmware and let the process finish till the final. Dial again *#1234# and verify if all is correct like the firmware you downloaded and installed before. Flash again same firmware if not.

Might be a corrupted EFS folder.
I have had the same problem for 3 weeks now. I've tried searching for a solution here and in other online sites to no avail. I personally tried flashing a new stock rom, flashed some odd number of modems, tried factory resetting etc. Nothing worked. I'm afraid it might be due to corrupted EFS folder which I still don't know how to repair.

Network not registered issue

Hi Guys,
I am writing this Thread believing that I will get a solution as Yota company has not provided any solution after 15 days trouble shooting. I just brought the phone from Russian seller through eBay.com to India and after 2 months of fight from the local customs office I just got my phone. I was very happy and was floating in air to have the first dual screen phone in my hand. The phone was flawless with dual screen was working awesome. The phone came with lollipop update. I switched on the phone with out inserting the simcard, the phone prompted for a small 350 MB update and I just update the phone. Then I just inserted the Simcard after which i started facing issue. The issue was the phone is able to read and shoe the service provider name but there was no network signal and it was showing only emergency calls. When i tried to make calls it showed network no registered. I tried with different simcard which resulted in the same issue. I though it might be a simcard issue and checked with my old phone but there was no simcard issue. So i just contacted the Yota tech team through mail to help me on this issue. They asked me do some basic troubleshooting but there was no use after 15 days they asked me to ship the phone to nearest service center which is in Russia. The issue is to and back from Russia customs will cost me the price of 2 Yotaphone fist generation phone price. So I through of resolving this issue myself and researched in online. I found that Samsung phones were also facing the same issue after update and tried all the solutions given in internet but there was no use. Finally there was a solution asking to root the phone and install the ariza patch which would solve the issue. I just rooted my phone and when I installed the ariza it showed it was not compilable for yotaphone 2. I just searched in XDA forums and could not find anyone reporting the similar issue with a solution. So I through of creating new thread in hope of getting a solution in this issue. Please help me in this issue by creating a patch or any solution which will me help me out of this. I am not able to use the phone as the basic call function is not even working reset the phone is a heaven.:crying::crying::crying:

Do you still have this problem?
I wasn't sure at first, I thought it was my sim card, but I have tried 2 different networks sims and they both get no signal in my Yotaphone 2...
The network's name does appear, so the sim must be being read somewhat, but I always get no signal.
I literally have no idea what to do.
I too turned the phone on without a simcard, flashed the RU latest rom, flashed TWRP, rooted it etc, surely that has nothing to do with it...?
@bharath9962 ! I fixed it!
I have no idea why this happened, and I spent a few hours trying to fix it, very angry. I downgraded to 4.4 to see if it would help, put back the native China rom that came with my phone (accidentally deleted my backup too...)
I bought a new sim card just for this phone because the old one did not 'work'.
This is not a popular phone so it's hard to find information, anyway... I'm very relieved now. I can only imagine you gave up...
I found the answer here - thewichitacomputerguy.com/blog/how-i-fixed-your-sim-card-does-not-allow-connection-network-g1
1. Open the phone dialer
2. Enter: *#*#4636#*#* (Once entered, you will be taken directly to a "Testing" page) [4636 spells INFO]
3. Tap Phone Information
4. Scroll to the bottom of the screen and you should see a button that says radio off. Hit this button and when it reads radio on Hit it again to turn the radio back on. <-- (Not a Typo)
I rebooted and waited a few seconds, no signal. I turned on airplane mode, turned it off, and it worked!
Now I can go back to RU 1.99 and reinstall all my stuff...

My country is in Asia but I believe this does not matter - the problem was that somehow the radio (cell phone function) was 'off'/glitched, and had to be turned on+off to make the phone function again. Using a different country's sim card would not fix this problem.
As I wrote above, we both share the fact that we first turned our phones on with no sim, and updated. Maybe just a coincidence...
Just try the guide and please let me know if it is fixed!

If you already flashed the phone to latest EU 5.0, you can skip 1-5
1. download via FTP: fw.ydevices.com/YotaPhone2/YotaPhoneFlasher/yotaphone2_flasher.exe and install
2. run flasher and download latest EU rom (2 - 5- 7)
3. turn off the phone and turn it on while holding volume down - this will boot the phone in "downloading..." mode
4. in the flasher press 1 (Flash the cellphone)
5. the phone is now on 5.0.0-EU1.1.124b and 2G is not working at all and 3G is connecting only to 2100 MHz (on my cell network)
6. download via FTP: fw.ydevices.com/YotaPhone2/Firmwares/CN/4.4.3-S01-003-CN1.0.3.32a.zip
7. unzip the file and copy \radio to c:\program files (x86)\yotaphone_flasher
8. run cmd and go to c:\program files (x86)\yotaphone_flasher
9. repeat step 3.
10. run next lines:

fastboot flash sbl1 radio\sbl1.mbn
fastboot flash rpm radio\rpm.mbn
fastboot flash tz radio\tz.mbn
11. reboot the phone and enjoy 2G and strong 3G signal

Hello!
I try to figure out what you did but I get stucked in number 10.
Actually I flashed my Yotaphone with the chinese radio the first time, but I don't get good connectivity.
Anyways I try to do what you wrote, but when I tipe the first line (first fastboot command), cmd keep saying waiting for the device... maybe is that I'm impatient but nothing happens.
I try other USB ports and nothing works...
So actually I don't know if I'm doing it right or if I have to wait for a longer period of time (10 minutes or more).
Any help would much appreciated.
Cheers!
Hi there,
you don't have ADB drivers installed. Google for "universal adb driver" and install. There is driver included with yota 5.0 firmware (C:\Program Files (x86)\yotaphone_flasher\Driver\Google), but any other adb driver should work as well.
And use original yota usb cable!!!
It shouldn't take more that a few seconds for those commands to execute.

Had the same problem
Hi all, I had the same problem when I flashed russian firmware (YD201) over my phone which originally had honkong firmware (YD206).
I can inform that for me it also worked to flash the Chinese firware with yotaflasher.
However, when I tried to only flash the radio, it seemed it did not work. So I flashed the complete chinese kitkat firmware with yotaflasher and then afterward just removed/renamed the radio folder when flashing the newest russian lollipop firmware. Everything working great now, even was able to do some ota's without any problems since the ota's did not update anything of the radio img's.
And indeed you first need to make sure that you have the fastboot drivers installed and your device gets recognized as fastboot device by your PC.
You can test this by doing "fastboot devices". If you device turns up there as a fastboot devices, then the drivers and connection from pc to phone are ok.
Good Luck!
Thank you deepmnd and tomgaga.
Actually I had to activate developer options... And then reinstall the ADB cause, aparently I had it but it didn't work.
After that the instructions worked perfectly, but I still have network issues.
I don't know if it is because I have a MVNO (Mobile virtual network operator) and the phone has to change between the networks ( the one that provides the network and the MVNO).
I think that when it changes from one net to the other is when I lose connectivity and sometimes I have to search the network and choose it manually.
So this problem actually happened to me and the solution was to activate Roaming services (but I dont' know if is actually the same problem).
Anyways I can see that I connect to EDGE, HSPA/HSDPA and LTE.
For sure there is a way to monitor the network and check wich ones works.
Another guess is that being a phone for the chinese market, and the lack of the 900mhz band is causing this ¿?
So at the moment I'm losing signal just by walking on the street and I live in a big city. It seems that LTE and H works fine but I don't have a a way to assure this.
When I will have a spare time I will try to reflash the phone with the instructions deepmnd provided and see if it will work.
Thank you for your help!
Any advice will be appreciated!!
Update:
I try tomgaga approach I will test it just to see if is the network or my provider
Does anybody know which bands different firmwares support?
Reception is incredibly bad in my case (206 flashed with EU firmware).
It'd be nice if somebody has any info on unlocking different bands for yotaphone2.

Here you have the bands
https://www.frequencycheck.com/compare-devices/qkjseR/yota-yotaphone-2-yd201/yota-yotaphone-2-yd206
I have the same problem as you, I will try this weekend to downgrade to the older chinese rom and check if the reception get better.
And if then to the latest RU rom.

Thanks for that, it helps a lot to clear the situation regarding the two models.
Now, taking in account deepmnd´s solution above, would it be possible to find those missing bands from the original 206 which are not available to the updated (and then international, 201-) version and add them individually, file by file via the fastboot flashing?
I followed deepmnd's instructions, and my phone now connects to GSM/EDGE, which was not possible before using the EU Radio (latest EU rom). Thanks for this!
Unfortunately it now preferably (!) connects to EDGE, although the LTE/WCDMA-Option is prioritized. I can force the phone to connect to WCDMA by using the WCDMA-only-option, but in this case it does not commit a fallback to EDGE if 3G is missing and I have no connectivity at all, unless I change the band-options and force a connect to EDGE. I'd like it to switch between the bands automatically, as my YD201 did without problems (in Germany).
Any hints to solve this problem?
Thanks in advance, Knut

Thank you! I had missed calls and did not know what caused them. Then I noticed this happened when I was not on LTE network but on WCDMA or 2G network. And this seems to have solved the issue for me as well.

[N910S] got it to work! Exynos Korean model, Eng-only custom ROM, no bloatware!

OK, *FIRST TIME POSTER HERE* so please excuse any unintentional ignorance of rules or etiquette.
I'm just super excited to get this phone working the way I like it, and it's all thanks to xda so I was moved to create an account to express my thanks AND hopefully help a few people back.
How? Well after reading through pretty much everything I could find on the N910S here and elsewhere, it seems that no-one (yet?) has been able to confirm a working mod that meets the following:
1. N910S Exynos Korean version
2. Some kind of custom English only ROM that removes the Korean characters from keypad and other network-apps
3. Removed bloatware
4. Easy-to-follow, how-to guide
Seems there were quite a few ppl who wanted the same thing so I just want to let you know what I did to get it working.
*PLEASE NOTE* Everything contained in this summary was found through over a week of tedious reading, research, trial & error. BUT in the end all the necessary information was contained, or linked to, in xda forums. It's just that all the relevant information and files were scattered over many different threads and topics. I'm just collating it all here to hopefully make it easier for the next person to find.
Background info: I'm technically competent but relatively new to phone modding - I've only rooted my HTC E8 before this to remove bloatware. This is my second project. I live in HK and started with a completely stock OEM Note4 N910SKSU2DPK2 after a factory reset. I then did the steps below in order (not including many failed attempts and re-starts, of course) These are just the broadstrokes of what I did, if you need to know how to do each step in detail then please search the forum. It's quite clear and there's no need for me to repeat it here anyway
As it's my first post and I'm in a rush to leave the house soon, I have not bothered with screenshots or links - I'm happy to provide if someone can tell me if the preferred method is link to the thread where the info was found, or you just want a link to the files I used. Again, they were all found through links in threads on xda anyway but I'll have to spend some time to find them again as I didn't bookmark them. Also, if you want the files someone will have to tell me how to upload them here. The filenames/packages are given in [brackets] so maybe you can just search for them?
0. Reminder to backup your phone and data first!
1. Root - was really easy using CF AutoRoot [CF-Auto-Root-trelteskt-trelteskt-smn910s] Just download to your PC and package includes Odin, which for first-timers is the official Samsung software used to flash to your phone.
2. Download:
- ClockWorkMod [n910s-cwm-recovery-6.0.5.1(1113).tar]
- SuperSU [SuperSU-v2.79-201612051815.zip]
- C Mod ROM [C_ROM_N910s.v2HNY.zip] (the site is Korean-based but google translate of the page was enough for a non-Korean like myself)
- N910S DPK2 modem file [N910S-20170114T050808Z.zip] The original thread had links to every modem variant they knew of, so should work with other S/L/K variants BUT of course I haven't tried them.
3. Copy files for SuperSU, CMod ROM, and DPK2 modem onto an external SD card and insert into your phone.
4. Put your phone into Download Mode (from power-off state, hold Vol Down + Home + Power)
5. Run Odin on your PC, connect phone. On Odin, click <AP> and select CWM file. Do not check or modify any other options. Click <Start> to flash CWM recovery to your phone.
6. Once it's done, disconnect from PC, and restart your phone into the new custom recovery mode (from power-off state, hold Vol Up + Home + Power)
7. Choose Install from zip and select the SuperSU file from your ext SD card. (I think this step may not be strictly necessary as it's part of CF AutoRoot, but SuperSU is always handy to have anyway)
8. Reboot into Recovery mode again (available in Advanced menu)
9. Install zip - now choose the CMod ROM file. Reboot into system and have a look around the new UI. It was at this stage that I noticed two things: my HK carrier SIM was not recognised, and as the ROM boasts some Note 5 features the Always On Display function would cause my Note 4 to not be able to wake up once the screen was turned off (manually or via time-out). I had to pull out the battery, restart phone, go straight into Settings -> Display and turn off the Always On Display functionality.
10. To fix the SIM card not recognised, reboot into Recovery Mode again and Install zip - choose the DPK2 modem file (or whichever version your phone's modem is). Restart phone, wait a few minutes and SIM should now work.
*ONE REMAINING ISSUE* Even tho my SIM is 4G/LTE, it seems to be connecting at HSUPA only. Could be reception, I'll check later. But I believe there's a way to select different LTE bands through secret codes or menu, not sure but I'll try that as well later and update if it works.
That's it - hope it helps! Thanks for reading, and don't forget I'm new to this AND a first time poster so be kind in comments/questions please

So by following steps in this thread https://forum.xda-developers.com/note-4/help/note-4-sm-n910s-sk-telecom-issues-t2929571/page2 for SKT, I was able to change to LTE Band 3 or 7 (which is what my sim provider offers) and get an LTE signal for data, BUT then I lose voice call functionality. If I choose Band 3 Preferred, it says band changed success, but just connects via HSUPA and I get voice, but no LTE (just like before, or if I choose Automatic)
Can anyone please help me figure this out? How can I get voice AND LTE? Many thanks in advance!
PS - also after I reflashed my modem.bin the baseband changed from N910SKSU2DPK2 to N910SKSU0DPK2. I don't know what this means nor if it has anything to do with the problem I've described above? Can anyone help to explain? Thanks...

Band 3 and 7 are supposed to stick with default settings. I tried it once during my trip to Malaysia and it worked flawlessly. Any chance you might want to contact your carrier?
The trick to switch from 4G-3G-4G works. ATT band 5 preferred

Have you tried switching to 3g only, then switching it back to 4g when available in your phone setting??
I had similar issue with 4g and apparently, this strangely simple trick solved my problem.
Anyway, I tried to download the ROM from the Achonapp but took me ages and I couldn't flash it either. May I know where you got the ROM from?

Tried your suggestion but now it shows No Service
*update* actually I think your "trick" works... After switching to 3G only, it wouldn't switch back to 4G and showed No Service. I rebooted the phone with a different sim and after a few minutes, it automatically connected to 4G AND I now have voice as well! So, all is working properly now and I'm a happy camper. Reboot with the original sim and still works and connects to 4G. So I think you're right it just needed to be "forced" to select 4G preferred. Thanks for the tip!
Yeah I got it from achonapp as well and it took a while - I think I left it going overnight. But the ROM did work for me. If anyone wants the file direct I'm happy to put it up on my google drive if it's not against forum rules etc.
But since then I've switched to miui8 which is also working pretty much flawlessly as daily ROM, but I haven't tested every single little feature of course. If you wanna try it - https://forum.xda-developers.com/showpost.php?p=70596588&postcount=797
