What does that mean? You cannot flash another baseband? Or you have successfully flashed another baseband but the problem persists?
Please check the following and see what option is selected?
1- Open Settings > More networks > Mobile networks > Network mode ?
2- Open Dialer > enter *#2263# ?
3- Open Testing Menu > Device information > Set preferred network type ?

I have successfully flashed another baseband but the problem persists.
the network mode is wcdma only . I want the 3g network only.
*#2263# this code didn't open anything.

In fact 3g and wcdma are referred to the same thing.
- Is your phone root? If so, open Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > scroll to 2263 and tap 'Launch 0' to launch the code.
- Did you try the Step #3 I've said above?

how to open testing menu ?

Click to expand...
Click to collapse
Testing menu is *#*#4636#*#* on every Android phones.
On Samsung phones this code has been disable, so you have to open it by another way.
Install Shortcut Master app > Menu > Search... > enter 'testingsettings' in the textbox and tap Search.
Finally tap on the search result to launch it.
You can also create a shortcut for it for later access easier.

If you have root, just open Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > scroll down to *#27663368378# for Service Main Menu or *#197328640# for Debug Screen. Tap and select "Launch 0' to launch.
If you don't have root, open Dialer, enter *#0011#, Menu > Back item (not Back key), Menu > Key Input > Q0, wait some seconds...
maybe
download this app scroll to the bottom click additional info then phone information then scroll to the middle of the page on drop down box and try one of the settings im not on a gsm carrier so im not sure which one
https://play.google.com/store/apps/details?id=com.cc.signalinfo&hl=en

Menu>Back
Menu>Input>Q
Menu>Input>0000 wait some seconds and Hello service menu )

If that doesn't help, you may need root and use Phone INFO ★Samsung★ app > Menu > 'Secret Codes' to launch the Hidden Service menu.

Before hand i am very sorry that I bump an old thread however, this pertains to this and i can't find any info on my current issue and following you has got me the farthest along with my problem.
My galaxy note 4 reads no service, so I tried the *#0011# approach (no root) could not find the menu, with the input method
Then I rooted it and used your app and was now able to access the menu.
However I still can not find the run ping test option.
My firmware is version 5.1.1
Model: SM-N910T

"run ping test option", what do you mean?

I am trying to fix it so my phone no longer reads No service, It seems like the fix is to go into service menu and run a ping test from basic info, but thats just what i have read in other forums.

I screwed up I think

So this morning I was fiddling with my Galaxy S5 (SM-G900W8). I was trying out those secret dialing codes because I kept getting a MMI error.
So anyway I launch up *#4636#* and I select "TURN OFF RADIO" and "TURN ON SMS OVER IMS" as per this website guide http://www.technobezz.com/fix-connection-problem-invalid-mmi-code/
As soon as I did that, my network was shut off and I tried re enabling it but it still won't turn back on. I tried factory reset, firmware install through Kies, took it to Telus, who didn't know what was wrong with it. I tried re entering my APN settings, selecting any Network in settings tells me "Your SIM won't allow connections to this network" even the network I am on (Telus)
I tried changing CSC, I am currently downloading firmware to flash in Odin, hoping that works.
But can anyone give me suggestions? I feel like since I just switched a setting, I should be able to turn one back on.
EDIT: Flashing official firmware in Odin did not work.

First, no need to screw up with those things such as changing APN or CSC...
I have turned off radio and then turned it on without problem.
So you can try to turn it on again.
Can you show the screenshots of it?

It actually says "Turn off Radio" every time I reboot so it seems to turn on that setting anyway. Which does nothing.

1- Got a question: in the 2nd screenshot, why it showed a full list of bands (Automatic/EURO/USA/Japan...), while in the 4th screenshot, the list is empty? In my device the list is always empty (as in your 4th screenshot), I don't know why.
2- 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).
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.

The network has considered your phone as a illegal device and refused service either because an identity of the phone is not acceptable, or because the phone does not pass the authentication check. I dont know why. It should be a false positive report.

I Fixed it!
I kept messing around in ServiceMode and finally found the setting to get my network back. It was NV settings that I reset under PROTOCOL. Told me to reboot and voila my LTE was back. SMS and calling didn't work so I factory reset and now everything is working fine. I knew my SIM was fine and my EMEI was fine. I knew it was something I could change myself.
Thank you for the help man. I am now going to never install that Phone info app again unless I have other problems lol.

Phone Nightmare, i dont know what i have done :(

i just bought the phone yesterday screwed up and ive been working on it for over 15 hours and im hoping someone of expertise can get me out of this issue.
I have a N9005 , SN: RF1D963X6PD
I live in Canada and use Wind Mobile (AWS BANDS) same as tmobile. I bought the phone and insterted my sim and noticed that i would only connect roaming. I then figured out that i had bought a international version and it didnt have the bands i needed to connect to AWS bands. So stupid me... not backing up anything... at all, thought it would be fine to use QPST and restore it with a AWS file that i always used to enable aws bands on a S4. Didnt work so i came across this thread and noticed someone mentioned somthing about using the note 2 qpst file , that also didnt work.I then noticed that my phone showed no bars or roaming. I go into mobile networks settings to search for a network and it just searches and never stops or sometimes it will say error. My imei still shows.
Im on Sammobile.com trying differant firmwares for the n9005 with odin and no luck, they all boot up and show no bars, no networks nothing, i feeling im looking in the wrong area of where the problem is. Im not sure what i have done. All help is greatly appreciated. Thanks

I don't know where I should start from, but here are some suggestions:
1- Try to flash the original stock firmware for your device. You can find your original CSC using Phone INFO ★Samsung★ app, look for the 'Original CSC' in the 'CSC INFO' section. Then open the menu 'Firmware Browser', enter that CSC into the CSC textbox to search and download the firmware.
2- 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 those 3 screenshots for more investigation.
3- If you want to add some bands to the phone, you may need the Qualcomm NV Calculator app.

Thanks for responding vndnguyen,
1, i did as you said and coincidently the firmware that it suggested was the same one i had already installed (which seems to the be most stable one of the ones ive tried) so im not sure if the csc code was just reading what i had already flashed or if it was a coincidence i flashed the one i was supposed to. But i did a fresh flash, wiped everything, clean cache and flashed and samething no bars.
2, when i try to go to service mode using *#0011# , its all blank, so no luck in screenshoting anything.
3, i installed nv calculator and wrote the code for my requested on NV 1877, but no change.
I screenshoted some info in phone info samsung app, maybe that can somewhat help you with my issue. Check the attachment below.Thanks again

a- As we all know the Galaxy Note 3 was launched on September 2013, but your manufacturing date is 04.2013? This sounds weird.
b- Your manufacturing date does not match with the S/N, so the phone is refurbished. You can check this by open the menu 'Refurbishment Check'.
c- Actually your phone may be N900A, but it has been flashed with N9005 firmware. Can you show a hi-res picture of the back sticker, behind the battery?
d- As your Knox flag is 0x1, you can root your phone (if it has not been rooted), then open the Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > 0011 > 'Launch 0', and follow the steps #2 above to take 3 screenshots for further checking.

yes you are correct, it said it was refurbished
ive attached a pic of the back sticker, im not sure if this may hint to anything, but the sticker on the back looks as if its on a slant (maybe someone changed it and put it on)
i tried what you said and once i click the launch 0 , the servicemode screen still shows up blank, i read in another thread that Samsung disabled it in N9005 ROMs. could that be why it shows up blank

The info on the back sticker are matched with the IMEI and S/N in the app. That means the back ticker are original. But the phone's hardware (mainboard) has been changed, it may be due to repairing or warranty etc...

Nope, Samsung only disable the service menu on some models (e.g Verizon). But with this tool (Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > 0011 > 'Launch 0') you can launch any secret codes that are available in your device.
Can you show me that blank screen? And also show me the screenshot of Phone INFO ★Samsung★ app > Menu > 'Secret Codes'?

Your device has been modified in unappropriate way so all service menu do not work as expected.
I dont know what I have to suggest now. Try to flash the stock rom to get it back to the original state.

I appreciate your time and effort , one more thing before you go.
I loaded on VISION X ROM, from there i was able to capture the screen shots you requested, they are in the attachments below.
Also i looked through your app phone info samsung and it appeared all my info was quite differant from when i first showed you it, now its saying my phone is a n900t with the vision ROM, I will also attach pics below, please let me know what you think. thanks

Try flashing the stock firmware and capture screenshots again.

update
after flashin with vision x and using blaze kernel i was able to look around the service mode menue and found NV REBUILD. i just went through every menu until i found it and bam, got roaming signals back, so i was happy, now i just have to figure out how to get the aws signal working, thanks for all your help and time

So the key solution is NV REBUILD.

try *#197328640# .. if that takes you to the service mode, then open the menu bar and click "key" and type "Q" , then open menu again click "key" and type "0000" (zeros) ....
if that first code doesnt get you in, use *#9090#

For some reason, that code doesn't work on many phones. You can use this way instead:
Use 'Phone INFO ☆Samsung☆' app > Menu > 'Secret Codes' > 197328640 > 'Launch 0'.
Note: Root is required for it to work.

solved
many thanks my friends. *#0011# do the trick.

Does your phone also remember the IMEI? Dial *#06# and check if the number matches the original IMEI. If it's NULL or starts with 0049, that's the cause.
If the IMEI is correct, try a different SIM.

The IMEI is not null or it does not start with 0049. The IMEI on the phone and the box is correct is also correct. Also I've tried different SIM card but still getting the same message "not registered on network".

Dial *#1234# and tell me what appears.

1- First, put your SIM card into another phone to make sure it works fine?
2- Second, open the Debug ServiceMode Menu and do the following: DEBUG SCREEN > NAS INFORMATION > MM INFORMATION (capture screenshot #1) > Menu - Back > MM REJECT CAUSE (capture screenshot #2).
And post these screenshots for further checking.
To open the Debug ServiceMode Menu:
a- If you have root, install Phone INFO ★Samsung★ app > Menu > 'Secret Codes' > *#197328640# > 'Launch 0'.
b- If you don't have root, open the dialer > *#0011# > Menu - Back > Menu - Key Input > Q0 > wait... until Debug ServiceMode Menu appears.

I have a quite similar problem. My phone is a 3UK (service provider) phone. I have 2 sim cards with me (MTN & Etisalat). My phone (note3) works perfectly fine. I have even rooted to resolve this issue.
Now the issue is whenever i put my MTN sim card it works perfectly fine on Note 3, however the moment i enter my Etisalat sim it will work for 10-15 mins & will stop working. I will have network bars but when i try to make any outgoing or incoming call it does not work.
Also if i use the same etisalat sim with my iPhone 5s it works perfectly fine.
I have tried *#1234# & the information that i got is as below:
AP: N9005XXUDMJ6
CP: N9005XXUDMJ4
CSC: N9005H3GDMJ2
Some of my friends told me to upgrade it to Kitkat and that might resolve the issue but when i try to check for updates it says:
Your device has been modified. Software updates are not available.
Please let me know what is the solution
Note: I am new to android world. So please consider that..

- What does it say when you make a call (incoming/outgoing)?
Please follow my above post and show screenshots for more checking.
- Regarding to upgrading it to KitKat, I doubt that will not fix your issue. However if you want to upgrade, you can flash the stock firmware via Odin. Use Phone INFO ★Samsung★ app > Menu > 'Firmware Browser' to download the correct firmware for your device, and flash it via Odin.

When I try to make a call it just says dialing.. And when I try to get incoming call it says switched off..
I have tried to check for firmware in phone info and got N9005XXUGNH1 . Not sure if I should install that or not.
Attached are the NAS info & firmware in phone info.

1- Please check and make sure if date/time setting is correct? Or it was not correct?
2- In ServiceMode Menu, select CALL END CAUSE and show the screenshot?

I asked for the date/time settings as in the MM REJECT CAUSE screenshot there is only log from the past. No any new log.
The screenshots you have shown are from the MTN sim card, right?
All info seem to be fine, I don't know why it cannot make or receive a call.
If possible, try to take screenshots for both SIM cards and compare to see if there is any differences.
EDIT: Oh NO, you need to show me screenshots from the sim card that doesn't work, NOT screenshots from the sim card that works fine.

Yes i have taken it from MTN sim which is working perfectly fine. Even my etisalat sim works for like 20 mins before it stops working.
Also i am downloading the N9005XXUGNH1 from Sammobile as you have mentioned before. But will it resolve the issue?
Attached is the screenshot of the same.
OK will attach the Etisalat sim & will upload in 5 mins

Attached are the screenshots of MM info, MM reject cause.
I am unable to open CALL END Cause. The moment i tap on it, it goes back to DEBUG Screen
I have tried to compare MM info, Reject cause with both the sim cards entering one by one & found out everything is same in Reject cause.
But MM info there is a slight change in MMC-MNC: 621-30 (MTN which works fine) & MMC - MNC: 621 - 60 (Etisalat which is not working)
LAC: 2ae8, RAC: 9 (MTN) & LAC: 7d15, RAC: 4
There are some changes in TMSI which is think is some sort of id.
Also want to know if I install N9005XXUGNH1 firmware on my samsung note 3 will this issue resolve?

From the screenshots it appears to be fine on both sim card.
You should take a screenshots when it becomes not working (after 20 min...)
