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 ?

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.

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.

You have a custom rom ask in the roms Q&A thread .

This problem is present from Kitkat to Lollipop.
It's not a rom problem.

Android MM and GSM

Hello!
I've sent my Note 4 to my friend who lives in Russia. I've unlocked it first. Global unlock by Idone.
Russia do not have CDMA. GSM only. So, he was using Note 4 and everything was OK.
Until he updated to 6.0.1 After he Odined PC1 suddenly GSM wasn't working anymore. He tried everything but nothing helped. He downgraded to COK1. GSM was working again. As I understand, he did OTA to PC1 and GSM was not working again.
Can somebody help with it? Is there some fix?
Please, help?
Thank you!

not work because, idone not function in 6.0

Yes, our app works on both 5.x and 6.0.1, it even works on not rooted phones.
His problem is related to the fact that switching from GSM to CDMA and viceversa on phones that needs GCF Setting requires that the user revert the GCF setting too.

Antila, just open our app, tap on GCF settings:
To have GSM working on note 4 tap those items:
UE Setting & Info >
Setting >
Protocol >
GCF >
GSM/(E)GPRS/WCDMA GCF ON
Reboot the phone.
Then go on Settings > Mobile Network > Network mode > GSM/UMTS
To Have CDMA working on note 4 tap those items instead:
UE Setting & Info >
Setting >
Protocol >
GCF >
CANCEL SETTING (GCF OFF)
Reboot the phone.
Then go on Settings > Mobile Network > Network mode > CDMA
