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.

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.

just one question, it won't trigger warranty void knox.. right?
Plus, I have my own region's CSC, but when I try to flash it via odin it gets stuck at NAND Write Start!!.. Anyway to fix it?

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

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.
hi,
i have the same problem on my galaxy s7 SM-G930 F
NONE of the ussd/mmi codes work!
when i type the code nothing happens
i instaled the PhoneINFO app and in the CSC Code card the Original CSC Code field is empty
but all other fields are filled:
Product code:
sm2g930fzsadhr
original csc code:
firmwares csc code:
DHR
Active csc code:
DHR
Availabile csc codes:
CRO, DHR
CSC Country:
Croatia / HR
Mobile Operator:
HT HR / 21901
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!
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!

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.

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 have a question, can I install the firmware from SM-G950F to the SM-G950N? I have 5 file versions of firmware from SM-G950F which has polish language.
I'm trying accomplish the same thing. Already tried flashing TUR firmware for G950F on a G950N. Odin outright fails with "secure check fail pit" error. I also tried repartitioning using "DREAMLTE_EUR_OPEN.pit" file and it also fails with the same error. Then I enabled "oem unlock" thing from developer settings and redid the all above, still no luck.
Here is a video of someone doing exactly what I want to accomplish on S7: https://www.youtube.com/watch?v=mnIoAN4grp0
I'm planning to try again in case I found another link for the pit file and maybe a firmware from another host.
Well, ****.
According to this comparison table (http://www.phonemore.com/compare/ph...m-g950n-vs-samsung-galaxy-s8-sm-g950f/5334991) SM-G950F and SM-G950N is slightly different in which bands/frequencies they support. I'm not sure if this implies a different baseband hardware or just a different software configuration for the same hardware.
is there any other way to do that?
flashing just the AP file in ODIN may work but it requires OEM unlock and trips KNOX thus I stopped trying at that point.

If that was possible, Samsung hadn't made a -N- model, but had called it also -F-!!!

Flashing AP image of G950F is prevented in the download mode, reason being the OEM lock. Based on this data I guess that G950N and G950F images are signed with different signatures, thus forcefully flashing the G950F image in G950N will trip KNOX, because it is unsigned and not different than a custom ROM image from KNOX point of view. It would even have the root baked in. This is why I'm 99% sure even though I haven't tried it.

It is not necessarily so as a general rule. AFAIK there have been compatible or even same hardware with switchable firmware images in the past.
Apart from that Korea always got exclusive model numbers that are different than global model no. regardless of it being different hardware.
In the end though you're still right because flashing of bootloader, baseband and pit file is hard blocked anyway.
Another point I should add is that there is now a custom recovery, a custom ROM image and a custom kernel image in the development section and they are all universal images which work on all Exynos models regardless of the variant (even regardless of S8 or S8+).
This further shows that the "model numbers" and blocking of cross variant flashing is not because of a hardware difference but just an arbitrary decision by Samsung. At most the baseband will be different between N and F models (because of CDMA support) but that's all.

Try flashing ONLY the CS/CSC HOME or FACT (the one without the word HOME) file from the "F" version onto your "N", which is just the user configuration file containing the languages. Make sure that "OEM Unlocking" is turned on, maybe with some tweaking you might be able to flash the full or partial "F" onto the "N".
In the US we have the Qualcom "U" version, yet are able to flash the "U1" (Universal multi CSC) firmware without an issue.
Don't try to flash this "U" or "U1" firmware onto any international Exynos model, it just won't work.

Since both are samsung firmwares, I doubt it won't trip knox counter.
I believe 950F, FD, N shares same hardware.
Samsung seems to make only 2 variants since S7. Exynos or Qualcomm version.
Seen many people succeed on 950f firmware on 950fd device. (950f/fd firmware can be flashed vice versa.)
Try to flash pit file (csc) and re-partition first.
If it doesn't work, then try to flash whole firmware file (ap, csc, boot..etc) with odin.
I'm also trying to flash 950n on 950fd. Waiting for my device to come in.
Good luck.
So guys, any progress on this from anyone ?
Hey people,
I have recently bought a G950F in a pre-sale from Vivo, which is the carrier I use here in Brazil.
I hate those carrier extras (apps, splash screen and stuff). Every time I buy a carrier branded phone I flash it to get rid of that stuff. That's what I wanna do with my new S8.
I went to Sammobile site and could not find a specific ZTO ROM. So I took notice about multi-CSC ROMs. I was then searching for a multi-CSC ROM which fits my phone, and I found this one: https://samsung-firmware.org/download/Galaxy S8/60y7/UFU/G950FXXU1AQCC/G950FOWT1AQCC/
This is for Uruguay (UFU), but also is exactly the same ROM I have in my S8, and included ZTO. Since it's for a different country/region, I flashed it (using CSC file, not home_CSC), hoping I was debranding. But I was not, my S8 is still branded.
How do I unbrand it? I have read that I must flash a OXM CSC ROM (it also includes ZTO) to change the original CSC of my phone, since it may not have changed because it was the same that it already had. Is that right?
I will try now an Argentina ROM (https://samsung-firmware.org/download/Galaxy S8/98v5/ARO/G950FXXU1AQDG/G950FOXM1AQDG/) which is OXM CSC.
Samsung was pretty strict about what carriers were allowed to install this time, at least in the US. Try to see if you can just uninstall the carrier specific apps, on my phone nothing was in the system partition so they could all just be removed.

Not here in Brazil. I can uninstall some, but not all carrier apps.
What bothers me is the awful splash screen. I can't remove that.
When I had a Galaxy S5 with a 3uk or ee splash screen if I remember correctly there was a oem folder or something similar which got loaded everytime irrespective of what rom you flashed, maybe that's the case with branded s8's?

I don't think so. I had my S7 flashed to debrand it, and that did not happen.
Yesterday I flashed my S8 with that argentinian ROM I have mentioned (https://samsung-firmware.org/downloa...G950FOXM1AQDG/). It looks ok now, without carrier splash screen and bloatware.
But sometimes I get a notification from AutoPreconfig, asking me to use new apps and configurations from my new service provider. If I open the notification, it says that to use apps and configurations from my new provider, I need to restore my phone, all my user data shall be lost, etc. I can press "ok" and nothing happens.
Why does that happen?

What i did was this:
1. get you phones imei:
go to dialer > dial *#06#
take a note of your imei without the /01 at the end.
2. go to phone dialer > dial *#272*(your phones imei)#
3. choose which csc you need and install it.
your phone will reinstall firmware with the new csc region you choose.
done.
Just done this to my S8 SM-G950F and switched from GLB(carrier) to XTC(unbranded) csc.
hope this helps.

3. choose which csc you need and install it.
your phone will reinstall firmware with the new csc region you choose.
done.
Just done this to my S8 SM-G950F and switched from GLB(carrier) to XTC(unbranded) csc.
hope this helps.

Not here in Brazil. I can uninstall some, but not all carrier apps.
What bothers me is the awful splash screen. I can't remove that.

If you want to disable apps you can purchase Samsung Package Disabler works well to disable apps you don't want.
Sent from my SM-G950U using XDA-Developers Legacy app
its so sad, i cant find an unbrand tutorial to make my s8 fully Samsungish without carrier stuff
Just flashed the latest version of Android 11, and it works flawlessly. Just have to install a Rogers CSC to it and you'll get 5G aswell.
My phone says it is now a N986U device instead of N986W.
If you have any questions, post them.

How?
The 986W version isn't going to be released until Jan 5th so you can download the 986U version from this site and install it with ODIN. Don't do this if you don't understand how to use tools like this, especially if you like your phone...

Did you have to change your CSC? Did you pick HOME for your CSC during the download? I noticed the *#272*IMEI# method to change your CSC doesn't work on the NOTE 20. Regardless, I see my phone still sees 5G. CSC right now is OYN??

Sorry for the late reply. I found the Rogers CSC by googling "Rogers Note 20 ultra Rogers Stock firmware"
I downloaded the whole 6gb file, but only used the Home_CSC from Rogers and used it with ODIN after I got the ATT update.
Have had no issues at all, and One UI 3.0 is a blessing.

Did you get it working? I have a Rogers sm-n986W but I moved to the states and now Verizon is saying my imei doesnt support 5g so now I think I need to Flash over to the US firmware... Can I just get the sm-n986u1 firmware and flash it using Odin?
