I recently bought a note 10+ and i am not getting any updates since 2021 , although security patches are rolling out for the device as late as feb 2023, so i found that flashing the phone to a newer version is my only option, now i just needed to know the csc of my phone which is OYN, which isnt carrier specific, looking for this specific csc online i couldnt find any firmware with csc OYN for the model, i only found carrier specific frimwares, anyway i continued searching for people having the same issue as me, i found that some people where flashing there U firmware phone with U1 with XAA csc. i just want to make sure it is safe bacuase i dont want to brick my new phone.
phone info:
Model number: SM-N975U
CSC: N975UOYN7FUI6
Service provider software version: XAA/XAA/SPR
Looks like unlocked, modem/PDA/ changed, CSC changed, and Updates disabled. Check IMEI through Samsung website some of the regions on the website will work for the IMEI warranty check to give you more info about the device. From that you should at least know some info which is the official firmware.
There are unlock services through server, supposedly however I can not vouch for any of these.
Eventually you can try Unlock bootloader, if that works, there is the most hope to try firmware.
If calls work and you can hear the other side and they can hear you, keep the software and give it away to a family member to play with if you need a more secure device.

Hi everyone. I have a Galaxy S8+ that I bought on BackMarket a year ago. The phone has been great, but has always had problems with some phone calls going straight to my mailbox for no reason, texts not coming in then suddenly working if I send OUT a text. After some research and contacting my provider (United States, Ting), I was told that this is because I need to enable VoLTE. My phone didn't have the option to do so and when I called Ting again, I was told that this is because my phone was the International version and VoLTE wasn't supported on that model.
I thought that was the end of it, but this week I had the thought that maybe this is a firmware thing instead of a hardware thing. Calling Ting again, they checked my IMEI and said my phone should be able to do VoLTE. Great! All I needed was Odin and the right firmware (I was thinking G955U1, TMB). So here's where things get weird. As I started to set up for flashing my firmware, I gathered the following info:
IMEI.info says I have:
Model: G955F Galaxy S8+ (SM-G955N)
Here's the info I get when running the "Phone INFO ★SAM★" app.
Phone Model: SM-N950F / Galaxy Note 8
Firmware's CSC Code: XEF
Bootloader Version: G955NKSU3CRI3
PDA Version: N950FXXS5DSC6
CSC Version: N950FOXM5DSC1
Latest Firmware: N950FXXSDDTJ1
If I'm reading this right, it looks like I've had a Galaxy S8+ running Note 8 firmware? At this point, I'd still like VoLTE, but even moreso, I'd like to just know what's going on and what I should do about it.
Seems like somebody installed a modded Samsung firmware on your phone. Check download mode for KNOX, I think it will be tripped (0x1).
If it is tripped then no Samsung Pay and stuff that depends on KNOX. If you are fine with that and just want to get VoLTE working, download the right firmware for your device and flash it to stock. If stock everything is important to you, I suggest contacting the seller on BackMarket and getting a refund or something if the seller didn't specify tripped KNOX.
BTW, if I remember correctly G955N is the Samsung direct model sold in Korea, so depending on CSC and what not VoLTE might not work. Best of luck
Thanks for the reply.
So I ended up solving this with the help of a few people over on Reddit. Here's what was going on and what the solution was, for others that come across this.
The phone was running v6 of HadesROM. I guess the creator of HadesROM uses the Note8's OS build as his base for the Note8/S8/S8+, which is why the phone was showing up as an N950F. And the phone itself was a G955N, which is a Korean model.
At the direction of a few people on Reddit, I used TWRP to re-flash with the newest version of HadesROM and set the Firmware CSC properly to a US Carrier.
When the phone booted back up, the VoLTE setting was present in quick settings and works great.
Hey Guys, I am in desperate need of help.
So I bought the note 20 ultra (model N986-U) from a seller in Texas (I live in Canada). The phones original csc code was ATT/ATT/ATT. I have a rogers sim card (csc code RWC). I noticed the phone is still stuck on One UI 2.5 because I am not connected to the ATT network.
So I tried changing the CSC using SamKey. I bought some credits, followed the steps and now for some reason my CSS is XAA/XAA/ATT.
I understand now that my phones model does not have a RWC firmware. Frija can't find the software for the SM-N986U running RWC but has no problem finding the software for the SM-N988W running RWC.
Is there any way for me to update my phone without bricking it? In an ideal world I would get OTA updates. Can I download the CSC_HOME file from the SM-N986W and flash it on my SM-N986U?
I'm really sorry for the noobish questions, I read so many threads and watched so many videos but I don't have the balls to experiment with such an expensive phone.
I know you can flash U1 firmware on a U device without any issues.
That's what I did to mine.
As for flashing W software on a U/U1 device, it's technically possible considering they are identical hardware, but I cannot say for sure what impacts it might have to the phone's performance.
You can always manually flash current U firmware.

Hey thanks for the answer,
I ended up flashing the W firmware on the phone and it worked flawlessly! Now the phone shows that it's a model N986W. OTA updates still don't work tho, even though the csc shows RWC

Glad it worked. Grab the latest firmware for RWC and then wait for the next update. (N986WVLU1DUB5)
Hi all,
Yesterday I bought an S10e under the impression that it is sm-g970F.
Trying to flash Android 11 I discovered that it is actually sm-g970N.
Is there really a difference between them?
Should I be worried that some functions will be missing/unavailable?
Also, in the settings, it appears as g970F. How did the seller change it??
I have the same problem i tried to update the phone to the latest sm-g970f rom (figured if it's already installed it's possible)
And non of the roms flashed only when i decided to try latest sm-g970n rom it flashed however i bricked the phone and i have no idea what to do now.

So after digging into the issue since i have the same problem here are my conclusions:
1. The phone is a Korean Variant G970N it is probably a renewed phone and not a new one.
apparently it's okay for an importer to take used phones (from Korea in this case) and replace all the cosmetics but of cause leaving the used MB.
Now here is what you should worry about, in order to flash the G970F Fixed Rom (there is no way you have updates) they used a Custom Kernel which means the phone was rooted and now Knox is tripped (this not reversible).
(Download Phone Info from play store and check knox if it shows 0x1 then your phone warrenty is void and some features won't be available any more for example - Samsung Pay).
So what should you do?
Well if you still have the option i would have demanded my money back!!
One thing that i am perplexed about is how in hell is this legal?!!!
If you no longer have this option or you want to keep the phone you have two option:
1. Flashing Korean Unbranded Firmware (KOO) which is pretty good it doesn't have bloatware or issues as far as i can tell, i only found one down side for it, the phone language selection is small but if you only need English (like any normal Human) then you are golden.
2. Keep the G970F ROM but bare in mind it will receive no updates and no security patches.
I am still looking for a proper way to flash G970F Firmware over G970N for now i haven't found any internet source that will confirm it's even possible.
So how did those importers\sellers did it, they probably flashed it with a Cellphone Lab Software (not Odin solution) and used a custom Kernel to fool Knox, like i said before this is practically a crime and i don't understand how can they sell used phones as new and get away with it!!!!
I had the same suspicions....
I'll try going to the lab that sold the previous owner the device and deal with them tho it looks like I just got scammed...
Sorry to bring this up again but I've just had an idea following JerryRigEverything's video:
What if I transplant SM-G970F components from a broken device that no longer works or in use in my SM-G970N which is supposedly new.
My N device is now bricked for some reason I couldn't solve, though my suspicion is that it has to do with incompatibility with the SIM card I use.
When my device did work, it worked great! ...besides battery issues that are most likely a result of the incompatibility aforementioned.
Will this work? If so, what components do I need? I already know I'll need the logic board but as seen in the video, there are several more antennas, should I just copy what Jerry did?

Hi Vegetto,
I am from India and buy a galaxy S10e from UAE, It is showing G970F in the Phone's about but the problem is It is a G960N. Now, When I see in Sam Phone Info app there is Bootloader version - G970N, PDA Version - G970F, CSC G970F.
It is also a Knox tripped phone. Knox 0/1.
But if I see in Samsung code by typing in keypad *#12580*369#
it showing like all option in Odin:
BL: G970F
AP: G970F
CP: G970F
CSC: G970F
Does this means I can flash new Firmware on the list of SAM Mobile website, with G970F series firmware, It also showing in SAM Phone Info App that there latest firmware G970FXXSEFUL1/G970FOXMEFUJ2/G970FXXSEFUJ2.
I am in India right now.
Please help me, My email Id is -- [email protected]
It actually means you cannot flash SM-G970F the only roms you can flash are G970N.
Also if you want the phone to get security updates you must flash the original phones bootloader version, my suggestion download the G970N KOO firmware it's a global firmware. As for the knox it is tripped and there is nothing you can do about it.

How can I flash the original phone's bootloader version?
Where from I can download the original phone's G970N KOO Firmware and is it official Samsung Firmware?
How are they able to flash G970F? Is it custom Rom or do they use the original one?
I searched that my phone is using G970FXXS4BTB3 firmware which Vietnam XXV and same number found at https://www.sammobile.com/samsung/galaxy-s10e/firmware/SM-G970F/XXV/download/G970FXXS4BTB3/322678/ in an old update in 2020.
So see the attached screenshot, can I flash its latest version with odin. Of course, there is a chinese written in recovery mode installed when I go to its recovery mode for flashing with Odin.
I have a similar problem right now on my Korean S10E. Device is SM-G970N. I need it to be in Turkish. Only Themes item in Settings is in Turkish- very interesting- The rest is in English. App names are mostly Turkish Settings app name is in English.
The bootloader is unlocked but the phone is not rooted, Knox seems not tampered.
Could not start OTA update at first, I have upgraded a few versions from PC via Smartswitch. Just then noticed OTA also started downloading. The rest of the updates went on from the phone until upgrading to 12, there was a message like "All of the updates were not succesful." OTA update no longer responded. This time I turned back to Smart Switch. Update finished this time and finally I am at the latest version.
I only need Turkish in Settings. I used some ADB commands and an app called MoreLocale2. It did not work either. This has to be simple. Turkish exists. Keyboard is Turkish but not Settings. Quick links and most other things are strangely mixed English and Turkish.
How can I enable full Turkish?
I recently bought an unlocked AT&T Samsung S20 ULTRA 5G (SM-G988U), it doesn't get any OTA updates, I found out that I would need an AT&T sim card to do so but I'm not an US resident, so I can't get one.
Since AT&T doesn't publicly publish their firmware files and I want to update my phone, I was wondering if flashing my phone using another firmware with a different CSC code like USC (US cellular), would be risky or is it a safe procedure?
This would be my first time doing this procedure and that's the only part that really got me thinking.
Thanks!
U firmware is identical, no matter which carrier it's from. So if AT&T's latest release ends in UH2 and there is also a UH2 firmware from US Cellular, flashing it would be just like flashing the AT&T firmware, if it were available
Also have same question I have Samsung S20 . SM-G988U , service provider software version SAOMC_SM-G988U_OYN_ATT_RR_0018ATT/ATT/ATT Baseband Version G988USQS2SUE2, I am not able to get new updates as I am not in US, I need suggestion which firmware of android 12 I should update on my phone.
Hello, I would like to preface this by saying that I don't actually live in the US. I got this used unlocked AT&T Galaxy S21+ a few months back and an issue I noticed after using it for a while was the fact I was not receiving any OTA updates due to the fact I was not using an AT&T SIM card.
Now I want to switch AT&T to carrier-free firmware where I will be able to get regular OTA updates automatically
My current specs:
Model: SM-G996U
chip: Snapdragon 888
Baseband version : G996USQU1ATLF
CSC : G996UOYN1ATLF
AP/CP : G996USQU1ATLF
Is it suitable for installation?
https://www.sammobile.com/samsung/g.../SM-G996U/USC/download/G996USQU5CVDB/1640229/
N.B/: May doing this flash will brick or damage my phone?
On SamMobile, underneath my device model, there list of several firmware labeled with different US carriers. As long as the firmware I flash is under the model number I have (SM-G996U), nothing should break, right?
Please suggest me firmware. I want to get rid of carrier barrier and want to get regular updates automatically safely.
Did you try the rom? I have the same problem
OTA is CSC based. You'd have to use Samkey to unlock the CSC to a unlocked US one.
Flash the u1 xaa firmware. Works on my phone in canada
I have a similar issue!
So I received a refurbished S21+, it is unlocked and all but it has AT&T bloatware and I can't update to oneui 5.0... I live in italy but this phone comes from Germany and apparently has a US AT&T firmware (SM-G996U-OYN-ATT). I was following a tutorial with odin to flash to SM-G996B with ITV, which is the italian version with android 12 and oneui 4.1.1 is it safe to do so and then get the android 13 update the standard way? Could I straight up get android 13 and oneui 5 flashing the most recent rom or is it even worse?
The other solution I thought about is that I could just get the U1 XAA, but i have U for now and I don't quite understand if it's completely risk free or not.

I'm having the same issue with my Samsung S20 Ultra 5G SM-G988U i bought the device yesterday and it accept my local Sim here but the issue is that there is limited features, for example I can't turn On/off my mobile data on and I can't change network mode like selecting from 4G to 5G
