Hi fellow XDA members,
I own a Galaxy Note 5 (SM-N920I) which was bought in Singapore under operator Starhub (STH). I happen to use this phone in India and I later realized the phone supports VoLTE but the firmware didn't so I stuck with using the Jio4GVoice app for a long time now and I'm done with it due to lot of bugs and call drops.
I looked online for solutions and found many that involved root or custom recovery to flash the so-called VoLTE fix. I have read articles that said the Indian firmware supports VoLTE so I So, I tried the following:
Download the Indian firmware and flashed via odin. But it fails with error specified file not found. Did a research and i unchecked the Re-partition and again tried and it fails at flashing system . So I re-flashed the STH firmware to get the phone boot up. I learnt that CSC is responsible for getting the region specific network to work.
Extract CSC from Indian firmware and simply flash it on odin. But, as articles say that I'll have 4 files for each boxes to place in odin I only had one tar (<firmware_HOME_tar.md5). Then I read, extracting the modem.bin file and ziping that to a tar file and flash it via odin will help. I tried that but no luck (should I factory reset it?).
Both the firmwares have a single file and articles say that there will be CSC_<firmware>.tar and CSC_HOME_<firmware>.tar.
I don't know where I'm getting wrong. Is this even possible or i'm simply wasting my time? I use samsung pay and S health extensively so I don't wanna trip knox.
Update:
I read that cache.img is CSC from here. So extracted the cache from Indian firmware and flashed that to my phone that has STH firmware. I used the Phone info app and found baseband has been changed and available CSC shows INS but active CSC is STH. Now I guess i just need to activate that CSC. I tried the steps mentioned here but it doesn't work.

here is another method you can try. but this only works if your phone supports it.
For firmware that uses a multi-csc code, you need to select a sales code before attempting to connect to a cellular network. This is especially true for 3G and 4G connections.
There are two ways to select a sales code:
1. Enter *#06# in the phone dialer to obtain the IMEI number for the device. You can then enter *#272*Device IMEI# to select a sales code. If your Samsung device does not return a menu, the product code is not a multi-csc code.
OR
2. Install an CSC changer app, such as the "Phone INFO" app. CSC changer apps do require root access, and they do not work on all phones and all versions of Android.
Hit thanks if it helps !
P.S. IT ONLY WORKS ON STOCK ROM ...! so you need to be on Stock Rom.

Thanks for your help. I tried solution 1 and it Worked
However, before trying out your solution, my device was in this state:
1. Flashed Singapore ROM
2. Extracted every file from Indian rom and repacked the tar except the system.img (as this was failing to flash in odin)
3. After booting I got a notification from SupportAgent telling me that unauthorized changes have been made, tap here to reboot to undo those changes
4. I then read your solution and updated the CSC to INS from STH. And device got factory reset and for the first time I saw VoLTE logo on my phone :victory:
5. I finished the setup and still getting the same error in notification from SupportAgent. So I tapped on it, and device rebooted to a new blue screen with sim card logo on it and then boot up to system.
6. Now, in the quick settings, VoLTE toggle is gone and I got WiFi Calling toggle instead. However I still have the VoLTE icon on the status bar.
7. So later that day, I redo all the steps.
- Flashed Singapore firmware (This time, the CSC Country was Singapore and the active CSC was XTH instead of STH. There was VoLTE toggle)
- Flashed Cache from Indian Firmware (CSC Country changed to India the active CSC was INS automatically. Now got WiFi Calling toggle)
8. I noticed other changes in the software:
- The gallery App doesn't show Grid view so I'm stuck with List view
- The Samsung Pay says, its not supported for this device
What do you think about this?

are you still able to use voLTE ?? after these steps.
about Support agent. Ignore it if you can. or skip it. you do not need this as there aren't any official updates after this. (this is only because now system knows that you have modified it, and it will not receive any update. if you can the disable the Support agent app via settings or if possible via root.)
samsung pay will Not work. as knox should have been tripped to 0x1, so Samsung pay like apps will NEVER work after knox trip.

If you only want the firmware and know what you're doing, then links will be at bottom.
If possible, Use the original charging cable that came with your phone, as sometimes there can be errors if you use an aftermarket cable.
If you don't know how to flash or convert from U to U1, read on.
As a precaution, I recommend removing your SIM card and SD card before flashing!
THIS WILL RESET YOUR PHONE!
Firstly, Download the modified Odin below as well as the firmware.
Step 1. Ensure that you have the Samsung drivers for mobile devices installed (which will also be linked below.)
Step 2.Extract the Firmware Zip that you downloaded, Open the modified Odin and click on the BL box, Then select the corresponding BL file.
Click the AP box and select the AP file, Do the same with the CP and CSC files by putting the matching file name into the corresponding boxes.
Step 3.Ensure USB Debugging is enabled and then shut down the phone. Then hold (In this order) Volume Down, Bixby, and Power button until you get to the Download mode warning screen.
Press the Volume Up button.
Step 4. Plug in the phone, and check Odin to ensure you see a blue box that says COM (also has a number at the end)
Step 5.Press Start in Odin and wait till you see pass, if it says PASS, The flash was successful and within about 10 minutes your phone will boot into the welcome screen.
If you are converting from the U firmware to the U1 firmware then you will have no carrier bloatware should have better performance and possibly better battery life as well.

Firstly I was on "U1..ARL1" then passed to "U CSAA" ( different than U1) and now I'm running latest N960USQS1CSD1 but my phone is bit laggy and still got the lags/stutters from lock screen when I slide quick menu and animations....Now I want to try itself U1 firmware and I hope all laggy and stutter will gone!
Do I need to roll back to ARL1 then flash CSD1 or I can do that directly?
Thanks
Thanks it worked for me
Flashed without problem but still got the lag when change the wallpaper :crying: If its infinity wallpaper there is no lag, but if I change the laggs/stutter starts.....What I supposed to do? Anyone? Also there is a lag on animations....
I flashed too many times and different firmwares and no luck...

in step 2 you say "Open the modified Odin and click on the BL box, Then select the corresponding BL file.
Click the AP box and select the AP file, Do the same with the CP and CSC files by putting the matching file name into the corresponding boxes."
Yet you only provided the ROM file. Where does the ROM file go and are there other files to flash that go in the CSC, CP BL and AP boxes?

Did you extract the zip? All of the files should be inside the zip.
I'll redownload them to check and make sure.
jd14771 said:
i have not finished downloading the rom file, i did not know the files were zipped inside, i think it would help if you mentioned this as i was ust going to flash the file whole as i downloaded it.
they are most likley there, i did not know to unzip the archive. So this will work on a locked us variant?

Yes it will work on any USA Note 9.
Thank you for bringing that to attention, I will update the thread, I apologize for the confusion.
I'm glad everything worked out okay! I'm at work right now so i apologize for the delayed replies.
Do you have lags/stutters on this firmware? (Especially on lock screen with none infinity wallpaper
when swiping down quick panel?)
Thanks converted AT&T to unlocked and everything is perfect
Will flashing u1 remove a carrier sim lock?

Call recording is only available on certain international firmware. It's a CSC feature that isn't available on the U.S. firmware. If you have root you can add the call recording feature to your CSC and that will be the only way to get call recording unless you find the specific international firmware that has it enabled but that firmware may not be best suited for your carrier/region. Also, enabling call recording will replace the call waiting & "add call" button which will make 3-way calls and ability to answer call waiting a problem. For this reason I always chose to not enable call recording. However, with root you can change csc anytime you need call recording and revert when you no longer need it. If I remember correctly, you also have to do a factory reset when adding the call recording in CSC because the csc/settings database is created on first boot only and adding this line in CSC after the phone has already booted and created it's CSC database will not enable call recording. It must be done on a fresh boot after a wipe/restore. I wanted to give you a heads up based on my experience so you know what to expect. Root is going to be mandatory unless you find the international firmware (rare) that has call recording enabled from Samsung.
Hi,
Here is my note 9 info (8.1.) from AT&T carrier, but I am not living in US.
- Model: SM-N960U
- Firmware: PDA version: N960USQU1ARH2 / CSC version: N960UOYN1ARH2
- Actice CSC code: XAA
- Service Provider:

XAA/XAA/ATT
So can I use the firmware N960U1UES1CSD1 which is uploaded in this thread to flash my phone into 960U1 ?
Or should I use the firmware N960U1UES1CSD1 which is specified for XAA ?

As far as i know u can flash any firmware related to N960U, N960U1 and even N960W.
for specific carriers after flash u will have their bloatwares .
Will a N960U converted this way take OTA updates in the same way that a phone that started out as a N960U1 would?
Is there a way I can make this work on a Linux based OS?

I have a Note 9 SM-N960F/DS model. I bought it from KSA (Saudi Arabia). The phone came with Android Pie (9) out of the box.
Unfortunately my friend rooted my phone and now i am running on "N960FXXU3CSFA/N960FOXM3CSFA/N960FXXU3ASF1" version with "Security patch level: 1 June 2019". I am unable to use my Samsung account and all the security features (finger print, Ratina scanner, Face recognition etc).
When i switch back to original firmware i.e
PDA N960FXXU3CSG1
CSC N960FOXM3CSG1
i got all the features functioning but my SIM card shows "Emergency calls only".
Any help will be highly appreciated. Thanks.

Well, My friend took my phone and told me that he will make it compliant with our local network and make it approved from the Telecommunication authority.
He has downgraded the phone with older firmware version i.e N960FXXU3CSFA/N960FOXM3CSFA,N960FXXU3ASF1. The security patch level is 1 June 2019
I have checked the Knox e-fuse which is not tripped which means its an official ROM and not altered.
Now, i have the latest firmware version downloaded i.e N960FXXS3CSG1 but when i try to install it in my phone it does not recognize my SIM card and phone is in "Emergency calls Only" state.

not sure how you check knox but if he really rooted then its too late and knox cannot state cant be reverted.
typically checking via software is not a good method . going to download mode and checking warranty state 0x0 means is not tripped. anything different means it been tripped/blown.
anyways that dosen't make you phone have no signal though.
i suspect he screwed up the twrp recovery flash procedure for twrp and botched the flash back to stock via odin.
read up on odin and how to use it. get latest version.(search and read)
read up so on how to get latest firmware for your phone and which csc your carrier is so that you can download the correct firmware and have best results for your sim carrier.( in doubt try BTU csc firmware)(but search and read about the subject of phone types firmwares and CSC)
also the firmwares your quoted seem old. not sure why you ended up using it but you should get one that is from july.
E.G.:
https://www.sammobile.com/samsung/galaxy-note9/firmware/SM-N960F/BTU/
(get the most recent! july 25th)( u can dl odin from there too)
on your PC, install samsung android drivers or simply install samsung smart switch. it will install the necessary components.
in it self smart switch can flash firmware automatically for your device. so you might want to try it first.
if you go towards the odin flash route and found the correct firmware or want to try BTU multi csc as suggested above:
put phone in download mode and unzip on PC firmware and flash with odin BL,AP,CP and CSC. But for csc choose csc.md5 instead of home_csc.md5
(be patient while AP is being checked before adding cp and csc)
edit: details steps on odin flashing procedure below

1. Extract (un-rar) the firmware file (i.e. to folder c:\Odin) ***

5. Power OFF Note9
6. Reboot Phone in Download Mode (1st plug-in USB-cable to your Note9!!!, push Bixby + Volume Down buttons, while pushing them plug-in USB-cable to PC
7. Wait until you get a blue sign in Odin
8. Add the firmware files to their designated slots
9. Make sure re-partition is NOT ticked
10. Click the start button, sit back and wait few minutes

last but not least don't listen to your friend or let him close to your phone again. reading and searching on xda is much better. everything has been already asked. you just need to search for it.

I haven't try SmartSwitch for N9 but worth to try as it should be able to detect proper csc for your phone.
Else find the latest firmware for your phone with Frija/Samfirm then flash with odin.

I have a Note 9 SM-N960F/DS model. I bought it from KSA (Saudi Arabia). The phone came with Android Pie (9) out of the box.
Unfortunately my friend rooted my phone and now i am running on "N960FXXU3CSFA/N960FOXM3CSFA/N960FXXU3ASF1" version with "Security patch level: 1 June 2019". I am unable to use my Samsung account and all the security features (finger print, Ratina scanner, Face recognition etc).
When i switch back to original firmware i.e
PDA N960FXXU3CSG1
CSC N960FOXM3CSG1
i got all the features functioning but my SIM card shows "Emergency calls only".
Any help will be highly appreciated. Thanks.

well may be your friend tried to change IMEI of phone which is illegal in any country. Match your IMEI with box by dialing *#06#, if IMEI are same then no need to worry. you need to register your phone IMEI with PTA by paying tax. after paying tax they will whitelist the IMEI of your phone and you will be able to make calls.
just for information, my note 9 is also brought from Saudi Arabia, but at that time one device was free, so i got my phone registered by providing my travel details to PTA and they whitelisted my phone.
Please guide me solution.

Hi everyone,
This is the first time I've done any phone flashing so please excuse any ignorance on my part.
I have the N960U1 and I'm trying to flash it to the AT&T firmware so I can use HD voice and wifi calling and such. I had the stock firmware fully updated to the November 2019 security patch before I started.
So this is what I've done so far:
1. Downloaded the latest U1 AT&T firmware files from sam mobile here
2. Loaded all the files into Odin 3.13.3, using HOME_CSC to preserve my data. The sam mobile file did not have any USERDATA files so I left that blank.
3. Flash was successful and phone rebooted normally. However, no AT&T boot-up screen was shown and no AT&T apps present (good), but also no wifi calling option in settings and I confirmed by calling another AT&T phone that HD voice was not present either (bad). Basically it seemed like nothing changed.
4. Found this thread with USERDATA (I used the one under the SGA-2 folder).
5. Re-flashed everything as in step 2, this time adding the USERDATA I obtained in step 4.
6. Odin said the flash failed, phone booted to the Emergency screen so I thought I had bricked my phone but luckily I was able to re-flash as in step 2, omitting the USERDATA again.
7. Again, phone boots normally but nothing has changed. Still no option for wifi calling.
8. Called AT&T to check if they needed to provision my phone or SIM card or something, but the rep I spoke to said there's nothing to do on their end and she sees that wifi calling is actually enabled on my phone.
I've also read that the newer Samsung firmwares are supposed to auto-detect which provider's SIM card you have in and load the appropriate firmware automatically, so I removed my SIM card while the phone was still on, turned the phone off, put the SIM card card back in, and turned my phone back on. Still nothing changed.
What am I doing wrong here? And why isn't the phone automatically loading the appropriate AT&T firmware since I have an AT&T SIM?
I should note that I've had this phone pretty much as soon as it came out and I know that the older firmwares did not have that auto-detect thing. I guess I should also be wondering why my phone didn't load up the AT&T firmware when I updated it to Android 9 the first time, or whenever they started the auto-detect thing. Is there something you need to do to trigger it?
Any help is greatly appreciated. Thanks!

did u use patched odin 3.13b?
also for it to change u need to wipe. so use csc.md5
because the sim was already in the phone. no changes are detected so no csc swap. ( sales code is identical as before because u never changed sims. so that's why u need to wipe. csc will auto detect and change only if a different carrier sales code sim is inserted. then it will wipe fone by itself. so in your case a simple factory wipe might do it or just reflash U firmware but this time choose csc.md5)

Thanks for the reply. I did not use the patched Odin, just the unpatched one. From what I've looked up, the difference seems to be cosmetic and the patched version failing less? For the most part, flash succeeded (except when I tried to mix and match a different USER DATA file). Are there any specific differences with the patched version?
I was hoping to keep my data and settings, but I will try to flash it next time with the wipe when I know I won't be needing my phone for a while. Do I need a USER DATA file to succeed? Because sam mobile didn't have it in their AT&T file.
Thanks again!

patached odin is to switch from U to U1 firmware and vice versa. there's a thread about it. maybe check it out?
https://forum.xda-developers.com/galaxy-note-9/how-to/u1-note-9-official-firmware-guide-to-t3927478
firmware links are old but the general logic on how to do it should still ring true

Yeah I saw that thread, but it seemed pretty specific about converting from AT&T to unlocked, and I didn't see anything about the other way around. And for some reason, the latest U firmware for AT&T on sam mobile is only 8.1.
That was actually going to be my first option (downloading the AT&T U firmware and flashing on my U1 phone). But as I mentioned, sam mobile's version is outdated.
Which actually brings me to another question: how is there an AT&T (or any other carrier) version of the U1 firmware? Is that supposed to convert the unlocked phone to a carrier branded one?

just use samfirm tool or frija to dl firmware.
Did you just get your shiny new S21 Ultra? And the first thing you noticed is tons of preloaded carrier apps that can't be deleted? This is how to fix that.
Convert your phone into the one that would come from Samsung directly with a simple firmware flash!
BACK UP YOUR PHONE! ALL DATA WILL LIKELY BE WIPED!
You will need an SM-G998U/U1/W
Computer running Windows
USB-C Cable for your PC to Phone
This is only for SM-G998U/U1/W
Step 1:
Download the ROM of your choice. The firmware number does NOT need to match your phone, as long as you have an SM-G998U/U1/W
From each link, click the latest firmware in the list (what ever the top one is) and on the page that loads, click the blue button that says "Download from website"
(You can only download one in a 24 hour period so choose U1 or W wisely)
SM-G998U1 (U1 is unlocked, no carrier bloat, US radio bands)
SM-G998W (W is unlocked, no carrier bloat, Canadian radio bands)
The only main difference between the two is the Canadian W Firmware supports all radio bands aside from (n260, n261), the file size is a little bigger and will take up a fractionally larger amount of space on your phone as a result of also including all CSC's, but will allow your device to connect to any tower frequency with the correct SIM.
The U1 Firmware supports all US bands and works across all Canadian carriers, but does not have any Carrier CSC's as a result of the smaller file size.
Thanks to @milan03 for the info
Best measure is to use the W Firmware as it will be supported, but if you are positive of your carrier will work and bands are the same as US carriers, use the U1 to save some space.
Step 2:
Download Odin 3.14.4 and Samsung USB Drivers
Step 3:
Extract all of the .zip files that you have downloaded, and install the Samsung USB Driver
Step 4:
On your S21 Ultra, enter download mode by turning the phone completely off.
Once the phone is off, hold the volume up AND down at the same time, and without letting go of those buttons, plug a USB cable in from the computer to the phone
Do not let go of the volume buttons until the Download Mode screen is displayed.
Step 5:
Open Odin and make sure the S21 Ultra comes up as one of the COM ports
If it doesn't try rebooting your computer, and then connect your phone again
Step 6:
Click the BL Button, and select the BL file you extracted from the Firmware .zip
Click the AP Button, and select the AP file (This will take awhile, do not touch anything, don't even click your mouse or try to do anything else on your computer, it can crash, just wait, make a coffee or something, because depending on your computer specs, it can take up to 5 minutes to load that file
Click CP and add the CP file
Now this last part here, you have a choice, however I strongly recommend you do not choose the second option at this time, however you CAN, but you might face stability issues.
When clicking CSC, you can EITHER add the CSC file, which is what I recommend, OR you can add the HOME_CSC file.
The differences between these files is that the CSC file will wipe your phone, but this is recommended, because when you are switching firmware's from a different carrier build, which we are right now, you want to delete anything left over that could conflict with the new firmware being flashed, however, you CAN flash HOME_CSC which will keep all of your user data on the phone, but this could leave old firmware files behind that could cause stability issues with your phone, crashes, force close apps, or even boot loops.
It's recommended to ONLY use HOME_CSC when you are UPGRADING on the same build (eg, if you are on SM-G998W and UPGRADING to another SM-G998W firmware)
So if you are going from U/U1 to W, it's recommended to use CSC, if you are going from W to W, Home_CSC should be fine, if you are going from W to U1, you should use CSC.
Step 7:
Once you have made your choice of either CSC or HOME_CSC, you can now click Start and it will start flashing the new firmware.
This process will take a fair amount of time, go relax and enjoy that coffee you made while the AP file was loading.
Once the flash is done, it will say Pass in green, and your phone will reboot automatically into your new official carrier bloat free firmware.
If you picked CSC, you can now setup your phone just like a new phone and restore your backup, if you picked HOME_CSC, you should be at your lock screen, and the phone is ready to use.
Congratulation, you are now on the Official Samsung Firmware with no carrier bloat as if you bought the phone directly from Samsung.
Troubleshooting:
If you used CSC and the phone did not pass and says FAIL, try the flash again with HOME_CSC, once the flash passes, you should be back at the lock screen, go to settings, search for reset, and do a factory reset, wipe all data because something did not flash correctly the first time so you need to wipe the phone after the successful flash to guarantee no stability issues.
If you used HOME_CSC and the phone did not pass, use CSC and the phone will be wiped when it flashes, and you need to set up your phone like new and restore your backup during the setup screen.
If it still fails to flash both CSC and HOME_CSC, Download Mode probably timed out from your computer taking too long, at which point, you can try doing Step 6 BEFORE Step 5.
Turn your phone off completely, load all of the files into Odin, THEN enter Download Mode and immediately click Start to start the flash. This will give you a little more time for your computer to make the flash and hopefully download mode will not timeout, if it still fails, try a faster computer or a different/shorter USB cable.
If you are with Bell in Canada and you did not get the pre-order bundle promo E-voucher prompt from Samsung Members App, flashing the SM-G998W firmware linked above will fix this and you can redeem your e-voucher and get your headphones and smart tag.
This is a video I made on the S20 Ultra for flashing One UI 3.0 Beta/Stable, however the process is identical, just use the files from here instead of the ones linked in the video description
I will be replacing this video with a dedicated S21 tutorial once I have have finishing editing the new video, but for now this will give you an idea of how it works until 5:30 in the video, after that it's mostly related to One UI 3.0 Beta/Stable for the S20 so there's no need to watch further than that as the S21 would be done by that point in the video.
Thank you sir.
So will this trip KNOX? My phone should get here next week (AT&T), and one of the first things I always want to do is get rid of the bloat.

No problem with KNOX.
But majority of bloatwares are issued of CSC carrier brand and it is impossible to change csc without root or using samkey...
So this firmware will be like other versions with same samsung apps unless I'm wrong.
Thanks for the guide.
If I may, I'd like to post a correction on the state of the supported frequency bands on Canadian and the US firmware:
- The U1 firmware doesn't only support T-Mobile bands, it also fully supports AT&T and Verizon frequency bands, which includes their unique LTE carrier aggregation combinations as well as the 5G non-standalone combinations with n5 and mmWave. That's in addition to T-Mobile's combos with n71 and n41, in both non-standalone and standalone environment.
- At the same time the Canadian W firmware doesn't support all 5G bands, it completely disables mmWave (n260, n261), which means the US devices with this firmware won't be able to access this super-fast flavor of 5G on any US network. It also doesn't fully support all US 5G non-standalone combinations in FR1 (Sub-6 GHz) range.
Thanks again.

If you're running a multi csc firmware (the one's linked above) you can change your csc by opening the phone app and dialing *#272*YOUR IMEI NUMBER# and from there you can pick the firmware CSC and carrier CSC to be whatever preinstalled apps you want. The W firmware has all of the preinstalled which is why the file size is larger.
As for the Samsung bloat, they all come with it, but a lot of these should be able to be removed using ADB without root.
There are some ADB scripts around that some skilled people wrote for removing bloat apps in bulk through ADB without root.

Hello!
Thank for you posting this @bANONYMOUS. Question if I buy the the U1 model can I flash the W firmware? My father is in Canada and I'm getting an early Bday present for him. Making sure when he gets it, that it will have the correct bands for Rogers!
Is there any qualcomm firmware that has an FM radio app?
I purchased from the US and flashed the XAC firmware. The final result was XAC/XAC/XAA is that correct? I thought all blocs would be XAC.
Also, I wasn't sure if repartition should be checked or not so I unchecked it.
No VOLTE or WIFI calling on koodo.
I bricked my device today so I'm trying to flash stock OS.
I started flashing it in odin, but it seems it gets stuck on "<ID:0/010> vbmeta.img" for few minutes.
Not sure what is causing it, does anyone have any ideas?
Just tried this with u1. Failed each time
I'm trying to flash u1 onto TMB device. Keep getting failing with sha256 is invalid. Is there a modified odin 3.14.4 yet?

Well, based on what my unlocked note 9 has:
Under the phone app settings there should be a setting for caller id and spam protection
Under system settings in the accounts and backup section there is should be samsung cloud,
Under system settings in the connections section there should be call and messages continuity.
These are all options I have on my unlocked note 9, but not on VZW FW S21 Ultra

**********This is first time am posting a guide so pardon me. *******
********As usual am not responsible for anything that happens to your phone.*******
*****Am not claiming ownership of the above technique, its what worked for me*****
I saw many posts here about people struggling to change csc from skc to koo or international***
Others had issue with their phone suddenly lost network and just displays emergency calls only****
so I have s10 sm-g973n which had csc as koo then flashed skc my mistake. The phone booted with annoying skc boot logo, and branded junk from the carrier. Then one morning the phone couldn't connect to gsm network!
I tried all manner of things to fix it. Rooted with magisk, flashed custom rom nothing.
Tried samkey to change csc still nothing. modified odin in flashing multi csc rom nothing.
Got some luck in changing csc by editing efs/imei/mps_code.dat using root explorer, text editor and vola the carrier junk disappeared. But still no network.
was told only way is to use z3x box or chimera to patch certificate but didn't give up. I posted question here in xda but no guide or response.
But that gave me an idea of what could be the issue- corrupt efs that needs the certificate to be patched. so got keyword.
After watching many YouTube videos I came across a video about a rom that has certificate patched. Just flash with odin and done!
I downloaded and followed the instructions. The phone booted up fine and after going through initial setup the network was back!
Not only did the network came back but the model changed to F, csc became oxm! You can now use tools like Samfw from too to change csc to your local region.
Later in the day, will be flashing firmware with my region csc.
Here is the link to the rom:

Did you find a fix for that? For me the internal memory become 32Gb. Is there a solution for that?
I bought an S10 that turned out to be a G973N(SKC) flashed to G973F-D/S(XSG). I think they used this method and these files to do it. I can't get the OEM unlock option to come up. I've tried everything. I am starting to think that it's because of the XSG country code. I was going to try to change it XEU (Great Britain) in SamFW but it just stalls and doesn't do anything. Any suggestions on what I can do here to change the country code? I need that OEM unlock option so I can degoogle it.
Hi guys,
I have I big problem with this rom man, each time I restart my phone i lost network and I have to reflash your rom and factory reset the phone to get it back. It's like it's forbidden to restart the phone, otherwise my network get lost and IMEI Status NG again.. Is there a fix for that? Thank you. Is there a for that fix?
Or do you guys have a rom based on android 12 for g973n u7 converted to dual sim that can solve this IMei STATUS NG? I watched on youtube some guys that have it but it's not free or I can't pay that from here in my cluntry the poorest country in the world.
Thank you guys.
