i have the verizon Note 10+ 5g (sm-n976v) and it has been unlocked. around the same time the CSC changed from VZW to GCF. it used to read VZW/GCF/VZW after the unlock it reads GCF/GCF/XAA. there are some things that don't work with GCF and i tried the *#272*IMEI# and it does nothing. how can i get the CSC back?

How was the note unlocked?
just inserted a new sim card from another carrier after being paid off.
with previous samsungs it would reboot with the correct software to match the sim. still boots up verizon and now defaults to Celsius 24 hour time and error when you click update software.
reading on here there is a key combination you can press to get to the csc menu but this CSC blocks it.
ive heard root plus samsung information app can change the csc. but i can't find root for this exact phone.
Did the CSC change on it's own? Have you tried using *#272*IMEI#?

The CSC displayed will match whatever carrier SIM is in it. Are you sure the last three digit code is now XAA? Because that should've read VZW to begin with and it never changes.
The last three is XAA. It is a Verizon and with a cricket or AT&T T-Mobile etc... it says GCF and just doesn’t work right. The CSC needs to be changed but I can’t find a root to change it that way and the dialer isn’t working for that. I tried a stock rom with and without nand erase and pit.

It changed on its own and the dialer code doesn’t work at all.
Something doesn't add up. For one, Verizon locks all their phones for 60 days, so your Verizon model should still be locked.
Two, you don't unlock it just by sticking in another carriers SIM card. Verizon has to the unlock for you.
Three, you can't change the last CSC code. If it says XAA, then you have a factory unlocked device, not a Verizon device. That also means if it says XAA now, it never said VZW.
And what is GCF? What carrier SIM card did you put in it?

My friend that isn't correct....Verizon doesn't unlock phones. I have had samsung phones on Verizon for years and they never had to unlock. Now with the new rule of locking devices for 60 days, I would imagine that none of us will have to call an unlock....it will happen.

Well, the SIM lock/unlock is controlled by the carrier, in his case, Verizon. You may not have to call them to unlock after 60 days, but they still implement it, even if it is automatic.
So yes, Verizon DOES unlock their phones.

So you're wanting a full Verizon firmware with WiFi calling and VoLTE, correct?
Are you on Verizon and using a Verizon SIM card?
I am on a Verizon phone with stock Verizon firmware and it changed my CSC. I have flashed and reflashed the Verizon rom and. It stays at GCF. I’m just looking to get to a menu to change it back.

There's no menu to change it back. And if the last CSC says XAA it's not a Verizon phone.
Again... Are you on Verizon and using a Verizon SIM card?
If you want help, you gotta supply answers to my questions.
I use At&t and T-Mobile. I would prefer a non-Verizon rom. But it is the n976v so there is no non-Verizon rom and I would be okay using the Verizon rom but the GCF is causing problems.

Here's all I can tell you.
There's no menu to change the CSC back to Verizon. The firmware on the phone detects the carrier for whatever SIM you insert and automatically provisions for that carrier and changes the CSC. The only way to change it back to VZW is to insert a Verizon SIM.
Here's the other issue. The N976V is specific to Verizon. Samsung didn't make an unlocked 5G version or a TMB 5G or an ATT 5G. You can't flash it to unlocked firmware then to another carrier firmware. It's only Verizon. And no matter what you flash it with, as soon as you put a TMB or ATT SIM in it, it will change the CSC. I did some searching and the GCF CSC basically means unknown carrier. My guess is again, it won't recognize other carriers since it's specific to VZW's 5G.
I'm not sure what all isn't working right, but my guess is the N976V isn't completely compatible with those other carriers. It's the first Galaxy in three years that's not universal for all three carriers.
If you want a Note 10 that you can swap between carriers, you need the N975U1. It's not 5G, but it's unlocked and compatible will all major US carriers.

Hello guys!
Well, I'm from Brazil and when travelling in USA decided to buy the new Galaxy S6 Edge. Looked for the unlocked international version but could not find it. So, searching the web I saw that the T-Mobile frequencies are the same from my brazilian carrier (Claro). Bought it!

Now I'm trying to get rid of the T-mobile stuffs (logos and apps). So decided to try to install a international ROM (SM-G925i - Brazil ZTO) with no success. Odin gave me "fail". Tryied to root (CF - autoroot using the S6 version because the S6 Edge version was briking my phone) and it worked. Then I tryied to install the ZTO room again also with no success.
So I change it back to default T-Mobile ROM, that I don't know if it is locked or no (will try my carrier chip later because the one I have isn't micro - need to buy one).
But it seems that the SM-G925T have some king of lock to block the instalation of ROMs from other countries (market!).
Is there any way to bypass it? In other words can I install a SM-G925i ROM on a SM-G925T S6 Edge?
Thank you all!
It's not just this phone. Most modern handsets do not allow installation of other model ROMs. Developers can make hacked up versions that work, but there are serious risks of problems with those ROMs. Your best bet is to root, install Titanium Backup Pro, and freeze the T-Mobile stuff. Don't uninstall anything. T-Mobile handsets are fairly unbloated as it is, so it's not a big order.
All right.. just updating... with the stock T-Mobile ROM I tryied my carrier SIM card and.......... "invalid SIM card" message appeared. So the T-Mobile S6 Edge IS locked! And it didn't even ask me for a code!
dc/dc, if the bootloader is locked is there a way to unlocks it? Maybe TWRP?
What I'd like to do is install a umbranded international ROM and continue to get the OTAs!
Thanks in advance!

The bootloader isn't locked. The phone can be network unlocked using an app that came on the phone (Device Unlock maybe?)
Yes, but the permanent unlock says that my device isn't elegible and the temporary unlock says that fails to apply the unlock! I'm already in Brazil so I cannot go to a T-Mobile store to fix it
Inserted my carrier SIM card with the T-Mobile ROM rooted but got the same message "Invalid SIM card".
It's insane.. that should be a way to get the network unlocked using other method than asking it for T-Mobile.
You needed to use that app to unlock it before returning to Brasil, and you would need a T-Mobile account. There are some sites that have the codes, so just do a search through here.

Please follow this and other threads,
http://forum.xda-developers.com/tmobile-galaxy-s6-edge/help/t-mobile-device-unlock-app-t3086772
It´s a matter of fact that if you got a t-mobile phone locked, ther is no way to avoid the app, and if you are not elegible, you just can wait for a rom that can be flashed to overcome the app.
I contacted T-Mobile and got the response that I need to have $100 in my account to be "elegible" to network unlock my phone.
Man, it's really insane! In Brazil all phones must be unlocked and if one is locked the carrier must unlock it for free.. that's the law!
TMobo, you sucks!

Honestly, it's not T-Mobile's fault that you didn't do your research.
There is no research that can fix a stupid american law that constraints consumers to be tied in a carrier allowing it to have "elegibilities" to be free. Honestly, I think acting this way isn't the american spirit, for shure!

There's no law involved at all. The telecom industry in the USA is simply different than in Brasil. It's changing, but no country will ever work the same as another. It's not T-Mobile or the USA's fault that you're having trouble. Sorry mate.
All right buddy... let's get ride of the "off topic" discussion. Thanks for helping me!
As I'll be able to be back in USA only at october and there is no way to send my Edge to TM, I'll continue to wait for a way to install a international ROM on it or wait for a MPCS ROM to unlock it after rooted and get back to TM ROM but network unlocked! This way besides having the TM stuffs and logos I can use my carrier SIM and continue receiving the OTAs at least!
Any news I'll let you know!

youre correct. I think alot of people are having a hard time understanding whats going on with these phones. Im in the same boat. Have an S6 edge TMOB and I cant get the damn thing unlocked. Scour the internet every morning for an answer..
I also have a 128GB S6 TMOB and the Metro firmware worked just fine. We need to be able to flash another rom to this phone to get the phone to accept the unlock code. Im not a developer so Im stuck waiting like you
I do the same.. Every morning with the hope to find a solution..
I think we only need a developer who want really do that.. I follow this forum and see amazing developers..
So.. Please help us.
Thanks..
I bought a new AT&T Note 10+ from someone and then unlocked it. I have T-Mobile as carrier. I can use it with t-mobile for general use. But I am reading there are some features that wont work even with this generation of phones. Such as VoLTE and Video Chat and may be small other features . Also Voice mail default T-mobile app wont work either.
When I search I find many people have Flashed their phones with T-Mo firmware on Samsung unlocked devices. But i could not find any reference to T-Mo downloaded on a AT&T unlocked phone.
Any suggestions. If it is possible to wipe out AT&T from it and make it a T-Mobile operating system.
Thanks.
I have a At&t Note 10+5g and running latest update from T-mobile using Frija to find the latest firmware and Odin to flash the firmware to the phone.

It's wierd because T Mobile isn't mm wave 5G, it runs on Band 71 which e n975u supports. So I'm trying to figure out if it's possible to get 975u to do 5G on Band 71.

You'll need to flash the combination firmware and use Realterm to change the CSC from ATT to TMB, I think I saw instructions for multi csc device changing, should work for your device as well.

Tmobile uses a mix of mmwave and band n71.
And the band 71 thing is a bit more then that. They list it as band n71.. which (after reading on it) is not setup the same as band 71. Guess you can think of it like how wifi 6 works.
The n975u and n975u1 just don't have the hardware support for accessing/using band n71
I got frustrated searching for T-Mobile SM-N976U but just got AT&T unlocked SM-N976U. Thiniking of flashing T-Mobile firmware. Thank you OP for the forum, else I would have been stuck on AT&T firmware.

First of all, you are a gentlemen and a scholar!! all this worked
AND i like to add the following to carrier unlock your phone.
the *#272# imei # thing does work to switch back and forth from att to tmo to att.
I got att locked phone and want it to work on tmobile. A lot on swappa going for MUCH cheaper than the tmobile phone!
went here to follow link to ask att for carrier unlock code
https://www.usmobile.com/blog/how-to-unlock-your-phone-from-any-carrier/
it says you'll get the unlock code in 24-48 hours. I got it in 15 seconds. well took me longer to log in and check status!
I flashed everything per @visualpro instructions. everyhting worked except the pop...i'm on tmobile. it said invalid sim. to me that said FU, i'm carrier locked and you on tmobile. so i did the *#272 thing went back to att. rebooted and it asked me for carrier unlock code. inserted carrier unlock code that i got instantly.
it unlocked and i did the *# thing and went back to tmobile and everything is all good to go!!
This was originally a att note 10+ 5g, as you can see it's now a TMobile unit!!
That's great it all worked out!!.. My mistake that I didn't specify mine that it was already unlocked AT&T phone. That was cool when you use *#272 imei and went back and unlocked it Credit goes to user @tyrone1 for that tip!
I was simply frustrated with higher T-Mobile prices on Swappa and after searching XDA many time, got the AT&T variant. On Samsung page it would show was Galaxy Note10+ 5G 256GB (AT&T) MODEL NUMBER: SM-N976UZKAATT.. but as long I'm getting fully T-mobile features, I'm all set

That's what I was saying too. On swappa they a premium for the tmobile version. Almost 100 bucks more. I got mine for 100 less than the cheapest tmobile one and it had 2 cases and a 512 SD card for 600 bucks. I saw the regular note 10 going for 690 lol.
Love xda!!!
Do I need to enter developer mode and enable USB debugging or anything before I do these steps with the 10 plus 5g? Also got the 10 plus non 5g can I do this to skip going to u1? Can I just flash from u att to u tmo and then do the IMEI trick or do I still need to go u1 first? Thanks
Can anyone confirm which 5G bands they have got working with this switch, also looking to bring AT&T SM-N976U over to T-Mobile.
Thanks.
Hi guys,
This is not gonna be much info but to let you know it is possible, at a cost.
So I bought an F936N - CSC: KTC (Korean). It came with the KT branding and the nasty bloatware with the extra setting menu for KT.
I was sick of it. I tried Samkey, I tried Samfw frp tool. Nothing worked.
I personally don't care about tripping knox, I don't use Samsung pay, password, or the file vault stuff. I just use google pay (Wallet now)
So I followed this guide:
Change CSC on Samsung Devices (Root)
Install X-plore File Manager app or any other root browser from the Play Store. [googleplay url=”https://play.google.com/store/apps/details?id=com.lonelycatgames.Xplore”]
Launch the app, go to Root Explorer option and change R/O to R/W.
Navigate to /efs/imei/ folder, edit the CSC code in the mps_code.dat file and save the changes.
Then go to /system/csc/ folder and edit your CSC in the sales_code.dat file. (System/CSC did not exist on my phone. but I did find the file sales_code.dat file within other folders that were named as the CSC such as KTC, SKT, KOO. I deleted all the folders except for KOO.
I just rebooted into download mode and flashed KOO firmware and it worked! No more KT carrier branding crap!
I've yet to try OTA. Not sure if it is no longer working or it is working. I'll wait for an update and see if it picks it up or not.
Update: OTA works
Not sure if we can replace the files from a different vairant such as F936B and flash its firmware... Would that give us the ability to change the phone completely?? Definitely something I am willing to tinker with on my phone but I would need someone to send me the files with an F936B and that person must have their phone rooted.
Cheers!
It can't be done with SamFW Tool v3?

you can change the csc with samkey! just disabble/remove all sim cards first from the phone, wifi also. no need for root!!
Do you still have your camera working, after Ruth? Is it possible to get root to do what is necessary and abandon them? In this case, will the camera work?

Once rooted you are never going to go back to stock. It physically burns a part of the SoC away. Samsung may have workarounds to fix this but no developer has, as yet, found any. It would probably be in the initialisation of the SoC in the factory. Very Low level format stuff...
Simple explanation, once rooted there's no going back even if you flash a stock ROM...

That is not an international device, F936B. Yours is an F936N device, It is for Korea and for use on their particular networks and not intended for sale by Samsung outside of that area.

It is definitely not an international, F936B, device.
The Korean, F936N, device is only compatible with 1 Indian 5G network band, N78 (3500). See screenshot and link...

You are out of luck as you have already found out. The only way around it would be to get the entire motherboard which has the Korean modem, and replace it with an international, F936B, motherboard and modem. Changing the CSC code or flashing a custom ROM, even if one exists, will not change the devices hardware.
TOP TIP: Always buy the model of device that Samsung intended for use in your location.
Thanks a lot for clarification brother. I think I’m gonna sell it asap!
So I am using AT&T version Zfold 4 model SM-F936U/DS in India and my software version is as follows:
Build number
SP2A.220305.013.F936USQU1AVGA
Service provider software version
SAOMC_SM-F936U_OYN_GCF_12_0003
GCF/GCF.GCF/XAA
Its stuck on android 12 May update.
I want to flash Indian firmware to make it Indian version of Z fold 4 for faster updates and enabling the call recorder.
What do I need to do? Any help will be appreciated. If this is answered anywhere please provide links to that thread and I will delete this one.
I am totally confused about CSC, firmware version, carrier version etc.
Not gonna happen without root, even then might be difficult.
The Indian model is a F936B model. Trying to flash the firmware on it is like trying to flash IOS on an android.
Did see a way to change CSC in the forum however I believe you needed to have the compatible variant as it needed the OXM ROM flashed 1st.

Your phone, F936U, is carrier locked to the U.S. network, AT&T, and if genuine, can only receive updates when connected on their network as unlike other models, AT&T issue their own firmware updates.
This model also has a locked bootloader which prevents the flashing of alternative stock firmware.
Also, it seems strange that a phone that was only launched in August 2022 would have a, "May", update. Install DevCheck, free from the Play Store and check if you have a clone phone.

Seems genuine. Your mention of a May update threw me.
It is running the F936USQU1AVGA firmware which it was launched with and therefore, has never received an update.
However, it is still a bootloader locked model, even though you have it carrier unlocked. The only way to update it is to insert an AT&T SIM card and connect to their network in the US. Other than that, you will need to do a search to see if there are any custom ROM's that utilises the locked AT&T bootloader. Alternatively, just carry on using it as it is

Thanks for clearing these things for me. I appreciate it.
No experience with AT&T but if they release their firmware online then you should be able to download & flash latest using ODIN.
Good Luck....

i dont think its possible, India phone comes with 2 physical sim slots or an esim option for the second sim where as the AT&T which you and I have, comes only with single physical sim.

Hi Chirag,
were you able to update your phone? I have the same model(SM-F936U/DS) and stuck with an old update and no new updates show up even though Andriod 13 has been rolled out for the Indian variants.
if there is no possibility of updating the phone then I might consider selling it! any help woud be appreciated.

There is no way I could find online to get the updates. Nothing works. The only way is to have US sim and be connected to AT&T network in US to get the update which is impossible. So I guess we are stuck with the old os version.

Hi Chirag,
Thanks for the revert. Thats a bummer that we can't do anything with the update. I can still make my peace with the slow updates but having no updates especially the security updates is very concerning.
I will keep you posted in case I happen to come across any solution to this.

Hi Chirag,
I can confirm the method mentioned shorty9210 indeed works! I just changed the CSC to T-Mob and the updates have started flowing. Just use the samFw.com tool to change the CSC, you will get T-MOB logo once you have changed the CSC but the updates will come by. It didnt delete the data too. Couldnt be any happier!
Give it a shot!
Cheers,
Amit.

you are a life saver sir! Thanks so much! I changed the csc to T-Mob and the updates are flowing! A quick question though do we need to change back and forth to GFC everytime theres an update? For now mine is at T-MOB.
BackgroundPrevious methods have only worked on US and Canada phones due to the dialer code only working on US/Canada phones on U and U1 firmware, and also the presence of IOTHiddenMenu on those devices' firmware. However, thanks to @K0mraid3's successful resurrection of the System Shell exploit, the Service Menu method can now be applied to International Snapdragon phones as well.
This means, any international Samsung S20/S21/S22/Fold2/Fold3/Fold4/... with Snapdragon processors, including but not limited to G9880, G988N, G9980, S908E, F936B...
The method used in this post is to directly launch the Service Menu by invoking the Service Mode RIL directly and bypass the need for IOTHiddenMenu or equivalent dialer codes. I found this specific command by decompiling Service Mode RIL APK and tracing through its AndroidManifest and BroadcastReceiver implementation.
How to (new method)1. Download Samsung Toolkit app onto your phone
2. Follow the instructions for running the app.
3. Use the Service Menu option in the app and follow from #5 in the below instructions
How to (original)1. Obtain System Shell access on your phone by following the instructions in @K0mraid3 's System Shell Exploit thread.
2. In the newly-opened System Shell, copy and paste the following command,
Code:
am broadcast -a com.samsung.android.action.SECRET_CODE -d android_secret_code://27663368378 -n com.sec.android.RilServiceModeApp/.SecKeyStringBroadcastReceiver
Ensure the entire command is copied correctly.
3. Run the command.
4. You should now see the Service Menu appear on the phone.
5. Follow instructions for Method 2 in the original How to unlock bands thread.
6. Follow instructions for Method 1 in the original How to unlock bands thread.
7. Now all bands, both 4G LTE and 5G NR that the hardware is capable of, are unlocked.
ProofI got my hands on a Korean model S20 Ultra (G988N) which has a Snapdragon CPU. Out of the box, it ONLY supports 5G NR n78. After doing the above steps, it now supports n5, n77, n78.

BonusOn certain international phones *#0011# or *#2263# don't work the way you expect them to. But with the service menu, you can access the same exact ones as the US models through the service menu (RF Test -> Band Selection to replace 2263, and Protocol State ->Basic Information to replace 0011)
In the case of the Korean phone, 2263 did not work at all. But 0011 brought up a totally different looking screen than the US version did.
LimitationsFor Exynos models owners - sorry, you're out of luck for now. I haven't been able to find a single menu that helps unlock bands on those models. The menus that open are VERY different and limited in functionality. Unfortunately, that's just how Samsung made it.
While "Disable CA Combos" is enabled by forcing GCF, it does not overcome hardware supported CA combos. So using a US SIM on the Korean phone for example, will still refuse to engage Carrier Aggregation on US carriers' bands.
Credits@K0mraid3 for the System Shell exploit
@peacey8 / @wr3cckl3ss1 / @bigdave79 for the Band Unlocking instructions on US/CA models
Respect!
Is there a way to check the activated bands before going through all the steps?
With *#0011# on my SM-9010 (S22 SD), I can see that my phone uses n28 here.

Yes you can check the current available bands by going into the Service Menu and RF Test, Band Selection
I would love to find a way to get this to work on Exynos chips. I have the intl S21+ and while I do have a 5G band for Tmobile in USA, I just can't ever connect to it.
You Sir, might just be a legend. I've got the Japanese Olympic Edition of the S21 here and never got to use the full potential of it here in Europe because of its limited band compatibility.
All other methods I tried so far didn't work, so I was just about to sell it- when I found this thread by accident. I'll give it a shot tomorrow.
Any idea if this change is persistent or will it be reset after an update?

All other methods I tried so far didn't work, so I was just about to sell it- when I found this thread by accident. I'll give it a shot tomorrow.
Any idea if this change is persistent or will it be reset after an update?

It's persistent, until a CSC change or a firmware update that makes changes to the CSC.

Thanks mate, I seemingly got it to work up to (and including) Step 5 of your description.
Just to avoid a misunderstanding: Do you suggest to go through Method 2 AND then Method 1 of the "How to unlock bands" thread or is one of them sufficient?
Edit:
Proceeded with Method 2, then 1. All Bands enabled, verified via Band selection menu.
Awesome!
Can I buy you a beer?

Glad it worked for you!
Beer would be appreciated too . My signature has links for that if you'd like
Any way to get *#73# back for Verzion and T-Mobile etc? Since at least the Jan 1, 2023 update, the the SamFW FRP tool, go to MTP tab and click on "Enable Secret Code for Verizon" no longer works on the S21 Ultra (SM-G998U1).
Can you PLEASE determine if this same command works on the S23U to launch the Service Menu, or what steps are needed to find out?
Now that Snapdragon is being used across all regions, I think this will be huge for US customers who want an unlocked bootloader if they can easily purchase an EU S23U and enable all bands with this method!

There's this alternative method:

If that still doesn't work, here's a surefire way that works,

I don't have an S23 yet but I'm trying to get S23 users to confirm they can launch the service menu/access band selection.
I see welshkiwi95 from that reddit stated he couldn't get Shizuku to work due to a VERSION_LOCKED message. For users that already have rooted their phones they wouldn't need a system level shell, wouldn't this be circumvented?

Welshkiwi95 is also me (also am not a he ).
I have been able to change my carrier vanity name but it also doesn't work at the same time. Very much thinking we need a new exploit or root. Because as I said in another thread, could be a OneUI issue or a S23 series issue.
Thank you, I've successfully unlocked China 5G bands on 908N with Korean LUC carrier.
Dear All Members,
I'm trying to see if anyone has successfully unlock all the respective LTE Bands for the G998UZKAWZW. I'm currently using the phone in Malaysia on a Malaysian Telco Provider and require the LTE Band 28 to be enabled and following the instructions did not yield any results in enabling the LTE Roaming Bands .
Hope to get some guidance from someone who has managed to enable all the LTE Bands
