I've searched the forums and no one seems to have an exact FIX for my issue. So I have a Galaxy Note 3 N9005 32GB black version, the phone works well in 3G, never had an issue with it but now my network provider recently upgraded their plan and offers 4G internet but my phone doesn't want to connect. The provider offers 4G through BAND 1 2100MHz and Note 3 N9005 does have that band but it doesn't want to connect. It only works on 3G and when I enable Mobile Data it says H+! Not once has it connected to 4G!
I wanna mention that my friend has the exact same N9005 phone and his phone works on 4G all the time. Both of us have the same contract with the same network provider!
The only difference between our phones is the CSC region, we have different CSC. MY SIM card works in 4G on his Note 3 and his sim card doesn't work on 4G on my phone. (we exchanged the SIM cards for testing). So the problem is from my phone not from the SIM card. My phone is also original, its not a Chinese clone! Its confirmed with "Samsung Phone Info" app from Play Store.
Here's a few things I already did that some of you may be inclined to recommend to me:
1 - My APN is correctly set
2 - I am on official stock Android Lollipop 5.0 latest version and the phone is not rooted
3 - I already did a factory reset + wipe cache partition
4 - I saw others suggesting that people may not be in the range of a 4G tower! Not the case! Like I said, I switched the SIM cards with my friend on a public bench, out in the open, not even behind walls. Of course and his phone connects to 4G with his SIM card and also with MY SIM card while my phone doesn't connect to 4G with neither of these SIM cards.
5 - In Mobile Networks > Network Mode, my phone is of course already set on 4G/3G/2G (auto connect) and by the way, my friend's Note 3 says LTE/WCDMA/GSM (auto connect) instead of 4G/3G/2G with the same language set on both phones. Why?? I know its the same thing and I know 4G stands for LTE and 3G for WCDMA but why does it appear differently on these phones?
6 - I already went to Service Mode via *#0011# and manually selected BAND 1 LTE, it says "no service" or "emergency calls only" if I do that so I switched back to "Automatic"
So what the heck is going on? This phone is giving me headaches! I'm close to smashing my phone! After this I sweared to my self this is the last Samsung phone I ever buy. Probably I will be switching to Asus or Lenovo in the future. Or any other phone that does NOT have this CSC BS! This CSC thing is a complete rip-off!
Im thinking that the problem could be my CSC perhaps?? My friend's Note 3 N9005 has a COA CSC (Cosmote Romania) and I have a XEF CSC (Unbranded France). Both phones are factory unlocked and work in all networks. They are not branded by any phone maker! His COA CSC is unbranded. Yes it belongs to a phone retailer but that retailer doesn't brand their phones, no bloatware, no SIM lock. If you buy a phone from Cosmote (with COA CSC) it works in all networks, unlike Vodafone or Orange who lock their phones and brand them.
What should I do? Should I attempt to change my CSC? If so, how? My phone warranty has expired a long time ago, so I shouldn't care that much about triggering Knox though not triggering it would be preferred.
Which path should I pursue? Should I simply use ODIN and flash a STOCK COA CSC (Cosmote Romania) or STOCK ROM CSC (Unbranded Romania) from SamMobile.com with the latest version of Lollipop? Would this trigger Knox? Will it affect my all networks unlocked status? I mean, I won't have to unlock it after that, right???
OR should I ROOT my phone, change CSC, then UNROOT? If so do you know of any method to root Lollipop 5.0 without triggering Knox?
What do you guys think? Whats the problem with my phone? Why doesn't it work on 4G? Because of CSC? Or is it something else?
Thanks!
The best way to confirm the model # would be to boot into Odin mode and look there.

What do you mean? Can you be more specific? I already told you my model number, its N9005!! Do you want a screenshot?
Dear OP, have you tried the other Samsung secret code? *#2263# then program it to accept LTE only.
That's the only foolproof way to get the Note to connect to LTE. In my country I only get 2-3 of the 5 LTE bars, so the Note wouldn't automatically connect to LTE or immediately stoop down to 3G through the settings. That specific secret code and setting is LITERALLY THE ONLY WAY TO GET MY NOTE 3 TO CONNECT TO LTE IN MY EXPERIENCE.
If that still doesn't get your phone to run LTE, either your carrier is whack or your phone is, and no amount of Cyanogenmod can fix it because your hardware modem inside the phone might be whack and you can't really do anything if that's the case...

I have already explained that there is nothing wrong with my carrier because I switched my SIM card with my friend's phone who has exactly the same N9005 model and it perfectly works on 4G on his phone. The only difference I could find in our phones is the CSC.
As for the other suggestion you sent me, I already said that I've been to SERVICE MODE. The code you've given me does nothing on my phone but as I can see from your screenshots, it gets you to SERVICE MODE. I've already been there through *#0011# switched to LTE/GSM only or LTE/WCMA only and I've explained that it still doesn't do anything.
Can someone please answer me this? Would it help if I change the CSC? Could this be the problem I'm having???
It may help if your CSC is changed it can do no harm .

Booting into download mode will confirm the model #. Looking under the ROM's settings is not guaranteed to display the proper model #.
Both phones are running the same ROM, bootloader, and modem?

Yes confirmed, same model, same baseband, same everything. The only thing different is the CSC. So whats next?
Did you try changing the csc by dialling *#272*enter IMEI#? Not sure if this method will work for your model of note 3.

It doesn't work! just my luck! I entered this code: *#272*IMEI-number# and pressed call button, it says "Connection problem or invalid MMI code."
I just tried it on my Note 2 and S4 and it works. Maybe the phone is not running a multi-csc stock ROM?
I don't have a note 3 to try.

Perhaps the code you gave me only works on older version of Android such as KitKat or whatever you have on Note 2... anyway Im using Samsung Phone Info app from Play Store and my CSC is XEF and under Available CSC Codes there is a bunch of CSC codes. Here I've made a sccreenshot:
From as far as I know there are only 2 ways to change the CSC: root or flash a different stock ROM
Yes, the note 2 has kit kat but the s4 is running stock lollipop.

Well unfortunately the code doesn't work on my phone. Anyway if you know for a fact, could you tell me this? Is it safe to reflash another STOCK rom from sammobile? Will it affect my phone in any way?
Thanks
Yes, it is safe to flash stock ROMs from sammobile.com.
I just flashed a local stock ROM and guess what, when I go to Phone Info app it still shows the same CSC! I still have XEF CSC, how can this be? Why hasn't the CSC change?
After flashing the stock rom, did you try the csc code I mentioned? Same thing happens when I flash a Rogers carrier rom over a Telus carrier rom. Once I select telus as the carrier from the csc menu, the Rogers app will disappear and the Telus app appears.
Ok after further researching I found a lot of interesting stuff so I'm gonna write it all down for other people who may need it in the future.
1 - If you have a multi-CSC phone and you flash a different CSC but which is in your "Available CSC" list but which you cannot choose or change without root, your CSC will NOT change. For example: I have flashed ROM CSC (Open Romania) on my XEF CSC (Open France) and guess what after the flash was successful and all, the CSC didn't change! It was still on XEF because ROM was in my "available list".
2 - If you try to flash a different CSC which is NOT in your list, then Odin will FAIL and softly brick your phone. For example: I got my phone bricked, trying to flash 2 CSCs which are not in my "available list": COA (Cosmote Romania) and DBT (Open Germany). In order to fix this issue all you have to do is to reflash YOUR OWN CSC, in my case it was XEF. Or you can even flash one of those CSC which are "available" or compatible so to say, such as "ROM" for example.
This is the firmware I currently have on my phone:
http://www.sammobile.com/firmwares/download/61565/N9005XXUGBOK6_N9005OXXGBOJ2_XEF/
These are the two firmwares I tried to flash on my phone, hoping to replace XEF with:
http://www.sammobile.com/firmwares/download/63441/N9005XXUGBOK6_N9005COAGBOK1_COA/
http://www.sammobile.com/firmwares/download/61464/N9005XXUGBOK6_N9005DBTGBOI1_DBT/
BOTH FAILED in Odin!
There are ONLY 2 ways to change the CSC on newer Samsung phones. Most guides online are based on KitKat 4.4 or older guides but for 5.0 Lollipop or even NEWER there are ONLY 2 ways to change your CSC:
1 - Root your phone and change the CSC. There are plenty of guides on how to do that online.
2 - You can avoid rooting your phone and use Odin instead, BUT accompanied by your stock firmware, you will also have to find and use a PIT file because Samsung as of 5.0 Lollipop uses different partitions for all the different regions. HOWEVER messing with PIT files is super risky and it can permanently brick your phone so its just better to root your phone instead! Dont waste your time trying to flash different regions/csc which is not in your available csc list, it won't work!
What can I say? Samsung is trying hard to block their users from changing their CSC... Why? They prefer their users buy new phones. Its pure greed yes but its what it is... For me, this was the last Samsung phone I ever buy. Im truly disappointed.

I've Boughten an unlocked Galaxy Note 3 SM-9005 on ebay. To use for straight talk in the United States. The first sim card i had in it was a normal sized sim card that i had cut (instead of micro) And after fiddling this sim card had worked from 4-5 days. Then i started to get the error message "No service" and "Not registered on Network" I had figured the sim was probably the reason to why i was not being allowed to call or message. So i bought another brand new micro sim card. And then put that in (Again with straight talk) and i am still unable to call or message. I have checked my imei number and it is the same as the one on the back of the phone. I have tried to re-register on the network within the settings on the phone. With no luck whatsoever. I have noticed that the CSC is not correct for the united states. And in hopes of fixing it i rooted and installed a custom rom. (IMEI is still the same)

Given the details that you have provided so far the most likely scenarios that I see are:
1) there is a mechanical problem on the SIM contact
2) the seller was on some form of a contract and has reported the phone stolen, so the IMEI is now blocked on some or all carriers.
DO NOT MINGLE WITH THE FIRMWARE at this point (and also disable any automatic updates of the firmware).
Also if you want further technical info (and not just guesswork) you should post the output from *#1234#

It really does depend on the issues xclub has brought up.
If it was me, I'd rule out SIM issue (the card itself) due to having a replacement, although it could be an issue with the SIM Tray.
And if it is used, then yes it is possible that it has been blocked by the original owner.
EDIT : Do you guys in the US have an IMEI checker for blocked IMEI's etc? in Europe we do it's called CHECK MEND.. Might be worth having a look or alternatively give your network a ring, they'll know for sure.

Ok so you have the same firmware as me, I am using BTU which is UK (I am UK) - So your CSC does indeed need changed to match you for US use - -- Firstly does your network support the available frequency required? (do you have LTE?) - If so you can change you CSC to your required region But another factor --- are you aware of region lock? has it been disabled that you know of? - this could cause some issues if it hasn't been deactivated - I'm not sure when changing CSC/firmware if it reactivates region locking or not
EDIT: I think only T-Mobile supports the N9005 in the US ( I could be wrong) --- Need a US user to chime in here I think to be 100% sure!!
Going with an Unknown carrier on CSC/FW- May not solve it

Don't see why not, plenty of people are buying them and plenty selling them.

That looks like EU version. Since somewhere else you mentioned that you rooted then the next thing to try is Region Lock Away:
http://forum.xda-developers.com/showthread.php?t=2470551
since the phone might now be "hit" by the EU region lock (an even simpler test would be to insert an EU SIM just to see if it registers on some network for roaming). If RegionLockAway fixes things you can then see what version of firmware you want in order to get LTE from your carrier.
If you want to sell the phone - being rooted might even be a plus, but having Knox 0x1 is certainly a major minus.
I did get region unlock and it did not work. And when i try to install the unknown firmware i am unable to flash it with odin i get all sorts of errors (I tried two of the unknowns) BTW thanks for the help
Please help, I flashed it to Android 5.0 and I did root for it and used region unlock app and still I face the same issue, please help me
Guys,
My phone never locks onto a 4G signal, as if its disabled.
Tried many solutions, editing lte_on list (my network was already there, never had to edit), setting property file to True, but none has worked so far. Im thinking of changing my CSC Code to BTU, since I have a stock firmware for that and most custom roms have the CSC for it.
I have never paid attention to what CSC Im on, since it gets changed and it always says applying multi-csc rather than displaying which one. So this time Im gonna flash a stock rom with full (pit) wipe and try to change it to BTU.
is there anything else that I should try before this step?
Its a N9005 Generic International device, purchased from a samsung store, and yeah I have the WCDMA/LTE option in network settings.
Thanks!

Hi guys,
I am new to Samsung but like many I was tempted by the Note 4. I bought my Note 4 in Dubai (unlocked and not tied to any provider) but when I tried using it in the UK with a UK SIM (EE) I am not able to make/receive calls when set on LTE/WCDMA/GSM but I can when I select GSM Only. Samsung UK is not interested, Samsung Dubai poit me towards Samsung Egypt (because apparently this is an Egypt region phone) and Samsung Egypt do not understand what my problem is and keep sending my region unblock codes when the phone is not region locked.
Has anyone had this before and if yes what did you do to fix this?

SIM works on my HTC One and 4G signal here good so I do not think it is the SIM. I updated firmware two days ago using Kies but no change. I am starting to suspect some sort of network blacklisting by Samsung but not sure. I also spoke to my network provider and problem not with them.
I want to test the phone in Middle East first to make sure that it is not some hardware fault bit if not my only option may be rooting and flashing different ROMs. I am also hoping that Lollipop may solve it but no way to get it now as I am not rooted yet.

Thanks for the screenshots. I compared with yours and it is now even more clear that mine is an Egypt phone. Do you know if I can flash the UAE firmware on my phone with or without rooting and if that would work so that the CP, SP and CSC are the same as yours rather than the Egypt ones?

my friends have this similar problem and its fix
This is how "you need a working sim from the country when you buy the samsung phone"
all you have to do is make a international call for 15 minutes to the original country
example u bought the phone in egypt so u need a working egypt simcard just call the operator in egypt and listen to the operator for 15 minuts from UK after 15 minutes (make it 20 minutes just in case) turn off your phone and change it with the UK sim card
this method works for me
u dont need to flash or root the phone
just remember this method only work with samsung unlock phones from middle east
I have my S7 Edge for a month now , everything used to work fine (located in Pakistan)
Two days back I flashed a new Stock Rom from UK to check country restricted apps (there were not much though) and I noticed on that ROM USSD codes were not working and neither do my sensors.
Now I reverted back to stock rom of my region, now the sensors are fine, but USSD codes are still not working. I tried the 2 ROM available for my region thrice, but still the same issue.
Please suggest what should I do?
Note: I didn't root my phone (because don't want to void my warranty since I paid extra $150 for that) nor do there's any network restriction on USSD.

Now I reverted back to stock rom of my region, now the sensors are fine, but USSD codes are still not working. I tried the 2 ROM available for my region thrice, but still the same issue.
Please suggest what should I do?
Note: I didn't root my phone (because don't want to void my warranty since I paid extra $150 for that) nor do there's any network restriction on USSD. Normally I use the codes to check balance and remaining data, it's so irritating to call the help center to know all the details without USSD.

You need to change your CSC to any other region or country.
The UK CSC no longer allows using the USSD codes.
I had the same problem using USSD so I just changed to a different CSC.
Once I changed to a different CSC the USSD codes worked perfectly.
Go to this link to download twrp flashable CSC's for your phone.

When don't you stop thinking that all people ROOT their phones?
"TWRP flashable CSC's": so you phone has to be rooted! Not everyone wants their phones to root, and there are people who won't want the KNOX-flag triggered!

After giving it a lot of thought you're right, perhaps that's the first thing I should ask,
maybe the reason I did not think of asking is because I come from a rooted family...
But sooner or later doesn't everyone root their phones? LOL
Have a great day!

Not quite true, I do have a UK version, and USSD codes work fine on mine.

The root method does NOT trip knox! Stop spreading your nonsense lol! It is done with the Samsung official engineering bootloader. Again, WARRANTY VOID: 0x0 :good::good:
I have been flashing/testing different carrier's firmware and have rooted the phone pictured below 3 or 4 times now and, as you can see, it's golden. Currently it is G935U but originally it was from Sprint.

how can i fix my s7 so CSC Codes can work again!
How to fix invalid MMI code on samsung galaxy s7
I have the same problem on my galaxy s7 SM-G930F.
When I check Divert if Unavailable (62) using *#62# I get the error
"Connection problem or invalid MMI code."...
It turns out that the G930F (BNIB sealed) I bought was a grey import and even though the hardware G930F is international, the firmware loaded is for the UK and the Phone INFO app shows the CSC to be "BTU" (see CSC codes) . And so even though the phone is unlocked, it does not function 100% in the Australian mobile network.
To fix this I had to flash the AU firmware for the CSC code XSA found at
SM-G930F — Galaxy S7 firmware
using ODIN.
After this the CSC is updated to XSA and all USSD codes work perfectly!
No rooting required!
A bonus for having the correct CSC/firmware for my S7 is that VoLTE now works with the carrier!
Hy all! This is my first thread.
And so sorry for my english.
So I bought a galaxy s7 edge (g935f) from the internet and it has a lot of weird issue...first this phone is a single sim t-mobile (hungary) version, but the software says this is a dual SIM version (935FD) I flashed a full-wipe 4 file from with Odin but after that the problem is still there. If I go to the ONE I menu the first imei is the phone's own imei, but the second imei is just a lot of zeros.
My second problem is that the wireless connections doesn't works.
The Bluetooth can't find any BT devices and the Wi-Fi is recognize only the 5ghz networks.(2.4ghz networks are invisible)
Is it possible to get this phone back to normal?
Is it should work if I try to reinstall the phone with smart switch? That app is download firmware that is match with the phone original carriers Rom.
Thanks in advance.
If the phone is the dual sim one (SM-G935FD) flashing the BTU ROM from SM-G935F (single SIM model) or the INU ROM from the SM-G935FD, it'll detect the second SIM slot that also works as microSD card.
By detecting it, it seems you have an G935FD...
try flashing one of those ROM's I have mentioned above with ODIN and do full wipe of the phone.
That will probably solve everything

Where did you get your phone from? Better return it...

Btu is samsung stock 7 firmware basically for Uk region it's available here on xda. Try to flash the full firmware and see if it's work for you or not. Also you can flash stock 935fd firmware.
