Hey ,
I have Galaxy S7 G930W8. Since I bought it with Android 7.0 Firmware G930W8VLU2BQB6 , I never received any update and when I try to check for an update, it tells me that I have latest one but it's not.
https://ibb.co/i9MjPv
The latest one is G930W8VLU2BQG4.
https://ibb.co/nsB7cF
Try to change your CSC to XAC. I have a W8 originally from Bell changed to XAC and it updates fine. To change CSC use *#272*IMEI# (it will wipe all your data so make sure to backup, disable account lock etc etc).
Before you try this tho, you can check whats your current CSC with the Phone INFO app from vndnguyen on playstore. See if it's already XAC.

Yes
Seems its something to do with the model then. mine is heroltebmc (so originally BMC CSC). Which one is yours?
Why not just flash the latest ROM with ODIN?

HI all,
With CSC change not possible using codes with latest UI 3.1 update what are options to change CSC?
For ex. I have SM-N986U unlocked Tmobile device but i changed CSC to ATT as im currently using ATT Prepaid and I'm on latest Apr update for ATT
How can i revert back to Tmobile CSC?
Do i need to flash Tmobile firmware using ODIN by first flashing to U1 firmware then Tmobile firmware or can i directly flash Tmobile latest firmware with Apr update using ODIN?
Will i be able to retain my app and data if I flash Tmobile firmware?
Any help will be appreciated.
Thanks
So you state csc change not possible then ask how to change it? lol.. and if it were as easy to just flash firmware in odin tgen that wouldve been the way to do it to begin with I would think lol
Update:
I was able to change CSC(ATT/ATT/TMB) to TMB/TMB/TMB but it was long and winded way. Just flashing firmware was not enough , need Tmobile sim to install carrier service and change CSC.
I followed the steps below:-
1) Did backup of my device using Smart Switch and removed my ATT sim.
2) Flashed latest T-Mobile firmware( N986USQU2DUC8 ) using instructions from post - https://forum.xda-developers.com/t/ota-and-non-ota-firmware-for-n986u-and-n986u1.4143833/ . Also, downloaded the ODIN (patched version) and T-Mobile firmware from links in the post. Flashed HOME_CSC too.
3) After rebooting phone with new firmware , the boot up screen was still ATT and CSC was still ATT/ATT/TMB.
4)Shut down phone and inserted Tmobile SIM i had lying around.
5) On reboot, i was asked to install Tmobile carrier services and on restart , Tmobile logo came on boot up with CSC changed to TMB/TMB/TMB.
6) Now, i have esim enabled and SIM manager showing up too.

thats the normal process.. that firmware is same for each carrier.. firmware is multi csc which changes based on sim inserted.. shouldnt have to go through all of that really.. i think most ppl who have issues are trying to change csc without a active sim card or on carrier locked devices etc.
glad u figured it out tho!

Well, the confusion for most ppl who are new to Samsung and CSC, like me , is that we could change CSC with code earlier and now cannot. Didn't have these issues with pixel and iPhone.

Yes, I was able to change CSC to ATT from TMobile, enable all LTE/5G bands before One UI update.Not, sure what u find so funny .
Yes, I'm aware that there is no CSC concept in pixel or iPhone or any other other manufacturer that I'm aware nor they are crippled in terms of hardware capability from carrier software like Samsung. LTE/5G bands not being enabled , esim not being enabled etc.

actually other devices are crippled in some cased disabled entirely.. for example u cant get a tmb oneplus 9 pro 5g and use it on verizon to get 5g bcuz vzw 5g bands are disabled in tmb variant..
its really the carriers to be honest..
and I say LOL all the time even in normal convo so not actually laughing sometimes, just say it out of habit

I have phones such as Z Flip3 5G and other models that do not change CSC like older models when following the flash procedure starting with U1, but the phones never prompt a restart. I have noticed it seems to be with TMB or VZW units. Any suggestion on how to actually get the CSC to change properly or is this something they are doing with new phones to avoid being able to use them fully on other carriers?

Go to the page, download theirs Samkey app, buy few credits on Ebay and you can change the CSC as you wish in a minute, the phone will reboot without loosing your data, it's the easiest way as far as I know
Hi, I have yhe following issue and I need your thoughts please.
I have a Telus plan, canadian with US roaming option.
I am traveling in US alot. I have a Note 20 Ultra U1 from Samsung USA. When in US I can only register on Tmobile and I can get 5G icon too. Won't let me on ATT or Verizon.
With same sim card in Note20 Ultra "W" variant, canadian one, it wil register on all 3 major networks in US. No issues with the sim, I guess.
Also in Canada won't get 5G ever.
My provider said nothing to do with them, Samsung told me the same.
I reseted all network setings my APN is ok. VOLTE on. Only getting acces to Tmobile.
Any ideea how I can fix this ? Is it related to CSC ? Mine is XAA.

Hey Everyone,
I have unlocked SM-N986U1 with the latest update installed (Updated with latest June update). I wanted to change my CSC to TMB (T-Mobile) so as to enable ESeim support. I tried using Samkey, wasted 1 credit too. It said CSC updated but nothing happened, my carrier still shows XAA.
Can anyone please guide me on how can I change CSC to TMB?
Thanks.

These links'could help. I think you have to flash the TMB Rom which enables and support the eSim on the phone. It would help to have a Tmobile Sim around during this process but I have heard others say it is not needed.

Yes you can. My device is from Xfinity and I have done the switch to any Carrier I choose on bootloader 2. U1 to U and back is doable. The key is to use the modified Odin as specified in the guide.
"
2. Download Patched Odin here
3. Unpack/Unzip what you downloaded in Step 2 (Odin Compatible ROm) and put in a folder. Lets call the folder "Flash"
4. Run Odin, click on BL, Browse to the "Flash" folder, add BL file from there, Do the same for AP (click on AP, Add AP file, this will take some time), Same for CP (click on CP, Add CP file)
5. Do the same for CSC (click on CSC, Add the file with the name starting with Home_CSC). If you use Home_CSC your phone will not get formatted and data will remain Intact
USERDATA Stays empty.
6. Now connect USB cable to your laptop (Only laptop and not the phone)>> Turn off your phone >> Press volume up and volume down keep them pressed and plug in the USB type C into your phone.
7. You should be in download mode now, press volume up. In Odin you will see that phone is added.
8. Press start in Odin. Wait for it to finish and let the phone restart (it will happen On its own).
9. Done

Thanks for the steps. Couple of Quick Questions:
1) I used frija to download the firmware (I typed CSC: TMB in frija, as its the first time I am using it, is it the right way)
2) I also checked the version in frija with the CSC: XAA, the version is same. How can I make sure that I have downloaded the correct TMB firmware.
Thanks.

You might want to extract the files and check for differences. The Frija tool has been kind of good to me.

So the Model is 986U/DS ? And is eSim enabled ?. That is the state you would want to be in. I understand the last XXX in the service provider software can't be changed. Mine didn't change and stayed CCT which is for xfinity but the as you can see, I have TMB/TMB, TMB/CCT. Esim is enabled and my Mint mobile (Tmobile) number is on it and I have a foreign physical Sim which is roaming on AT&T on the physical slot.
You might be close.

Also picked this nugget up from another thread
"You have to flash full tmb firmware. Not xaa tmb but 986u tmb firmware. The esim is in the user data section you'll flash"
Others have suggested you have to do a factory reset or flash the actual CSC file not the Home CSC which means you will loose DATA. I was doing this on a phone I had not setup yet so didn't mind loosing DATA. I am also assuming you have a TMB sim card in the phone because I understand that is needed so the phone can connect to Tmobile and download the carrier data files that actually changes the CSC after a clean flash.
These are just some of the things I picked up from here when doing my conversion.

Yup I used the TMB version only. The model Number changed to 986U/DS. In About phone, it shows me the IMEI of the Esim, but its greyed out.
The only thing I dont have is the T-Mobile Sim. I think thats whats causing the issue. I will arrange a t-Mobile sim and try it tomorrow.
Thanks for all the help.

Since the OP looks like problem solved, and not wanting to waste new thread, i have similar issues, can you help?
I have an S10e I recently broke (amazon renewed w/U1 FW), so I got another S10e from amazon, renewed which appears to also be U1 FW.
Except the latest, the replacement phone, the one I have now, NOONE can hear me, like all the time!!!!!!! Dead spots everywhere! Its so annoying. Its like i have a bad Mic? Or something...
This didn't happen with my identical phone, the one I had prior to this one, using identical sim.
I'm on Mint mobile, which is a TMO MVNO and currently have XAA/XAG FW running on the new S10e, the new one w/bad Mic or FW problem
It appears I am on U1 Unlocked USA firmware on latest phone ( i may have flashed FW Odin when I got this new one-to be safe- i forgot)
ALSO: BOTH renewed S10e's I've Purchased from Amazon, when lookup the IMEI, it shows as the AT&T Model. Which i understand the U/U1 FW can be swapped, BUT, both phones were advertised as U1 Models for the Hardware, so they sold me U models but they flashed with U1 FW probably to make more money. (this may seem trivial, but Samsung specifically has stated TWICE, that I couldn't Beta Test their last to major android FW's, because my phone shows as At&t on their end, and not the truly unlocked U1 model, for which the beta tests were for. And i was told when i purchased it was fully unlocked U1 ver. The phone itself even says its 970u1 in settings etc.)
Are there ANY hardware (including frequency bands) differences between U and U1 Models???
Is it somehow possible that my CSC, or FW on my phone is affecting my phone so badly that people cant hear me like 88% of all calls? Like should i flash different FW, or reflash or use different CSC??
Is it possible that if I went with a locked TMO FW (or another) that I could possibly, maybe get better reception so folks can hear me better? Or hear me more often or more frequently?
How often do mics go bad or get dirty on these? Can a mic be cleaned?
I have been in the other Note 20 flashing thread but I am stuck. Tried so many ways but can't get the TMB csc to stick, always shows only XAA. I have TMO sim card too. Not sure if they blocked it on the newer releases of the phone
Has anyone tried Samkey to do this? Heard it only takes 1 credit but smallest amount of credits to purchase on ebay is 10 and I dont feel like investing more money into this effort

U1 (XAA) device has it. This is my 986U ATT converted to a U1 XAA device.
So looks like it doesn't work with non-USA or different SIM card.

Unfortunately it's the CSC code that determines what features are available.
I did a CSC change on mine back when dialer code/IMEI still worked.
My phone was a stock 986U ATT device. I changed CSC to XAA and loaded U1 firmware.
My phone didn't retain the XAA CSC, after a 3rd reboot, but all the stock features remained.
Call and text on other devices works (normally blocked by AT&T), and Smart Call works as well.
Still can't get eSIM working, but that is only available for T-Mobile CSC.

It's changed... All AT&T U devices will retain ATT in the 3rd set (???/???/ATT) as that is the original sales code for the device.
Having XAA/XAA/ATT with U1 firmware should let you have access to some XAA features.

It is not possible to change CSC without tripping Knox. You must unlock the bootloader to change the CSC.

Unlock the bootloader and use Odin to flash OXM firmware. OXM is multi-CSC, so you should be able to change region to India.
Don't forget you can use the Search function to look for solutions to questions that have been asked many, many times before.

If you unlock your bootloader, you can install any CSC you want, so you'd just download INS firmware and flash it using Odin.
Or, you can flash the OXM firmware and simply change the region to India, as I stated in my first reply.
Ok i got that now second major issue is that i cannot unlock my bootloader as my developers option is not showing oem unlocking
no need to unlock your bootloader to change the CSC, just use this application to do so

Can you suggest best US based csc with regular ota updates as i am not getting ota update on gcf....stuck on may security patch update....
Can GCF based devices get ota updates i read it in someone's post that they can be only updated via odin or sideloading
GCF gives more LTE and 5G bands support so maybe that's why your phone has it set on that. You can change it to XAA as it's bloatware free and gets regular updates.

Wanted to ask it just out of curiosity....there is no way to change my csc from USA version to Indain version....by any means?
I don't think this is possible... and that's why Samsung has different variants for different countries ...
Okkk....
But by any chance u get to know that it can be changed to Indian csc please do let me know it will be very helpful
Thinking of flashing this firmware update via odin....device model number : SM-S908UZKEVZW
Region:VZW
OP, Are you sure it is an "unlocked" version? Based on he last three charactors of the model# you provided says it is a Verizon branded phone. Yes, technically it was unlocked after 60 days, but since you are not connected to Verizon's network, that may be the reason you are not getting OTA updates.

As for unlocking the bootloader, none of the US variants' bootloaders are unlockable.
I changed my csc code from GCF to USC and now in sim card manager settings it is showing only sim1 option and esim no sim2 option is available
