Hi all, i wondering if someone experienced with XT1710-08 model.
If you have changed ZUI based OS with a retail one, please tell me if you haven't changed modem during flash and how did you do that.
I have read about someone has got issues with connections and radio after changing from a specific model to a retail.
Thank you all in advance.
I have your same model (XT1710-08 Chinese version with ZUI). I installed the Verizon retail firmware for XT1710-02 that you can find in firmware-center site

Thank you very much for your answer. Why Verizon and not retail NPSS26.118-19-1-6?
Have you evade fastboot erase modem1st e 2st?
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.

No idea what gcf is, but it shares a rom with Verizon. The real question is how do I get the gcf/gcf/xaa to xaa/gcf/xaa?

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.
Hi all,
I have a s9 phone which, to me, looks like having contradictory model/FW (This is the way I bought it):
Model is: SM-960F
Service Provider SW version is: SAOMC_SM-G960F_OYN_XAA_PP_0003 ...
XAA/XAA/XAA
From what I've read, the OYN CSC is for the USA version 960U/960U1, yet I have a 960F.
I can't get OTA upgrades ("Current software is up to date")
What official FW should I flash to upgrade to the latest?
Thanks
More info on the HW
More data on the phone:
Installed CPU-Z to get some data on the hardware: According to CPU-Z It's a snapdragon 845, and the model SM-G-960U, so definitely not SM-G906F.
Why does it say SM-G960F in the "About phone" screen?
Also the Samsung health app does not work which implies this phone was rooted some time? (not rooted now)
So it looks to me I should upgrade to SM-G960U1 firmware (XAA) like what is currently installed. This should work and not enforce a factory reset
Can someone confirm?
Bump
Anybody out there?
I bought a second hand S20+ that is supposed to be a verizon model. It doesn't have the standard verizon bloat software so I am doubting it is a verizon model and more like and unlocked version. But on the software update it lists a VZW samsung site to see the software change log. How can I determine what version this phone is?

Check the original CSC. Go to Settings, About Phone, Software Information, Service Provider SW ver. On the bottom string if the last three letters are VZW it was originally a Verizon Branded device.

I now have new doubts. My build number is QP1A.190711.020.G986U1UES1BTK1 which doesn't match anything on the verizon website.
And the android 11 update isn't showing up on my phone.
So it appears I have the G986U1 software and not the G986U version which got updated for verizon. Is it as simple as downloading and flashing in odin the G986U vzw firmware?
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.
