changed region and bug reactivaton lock - Samsung Galaxy Watch

Hello.
Changed the region to sm-r815U in the hope of improving autonomy. But after the reset, it is impossible to log into my Samsung account. Writes that you need to accept the user agreement, which has been updated. It is impossible to accept it from the desktop or from the phone.

Changed the region to sm-r815U

sdb command launch_app csc-manager.csc-preset
chose the very first region on the list. Did not disable reactivation lock ..
I tried to change the region back through the Boot Mode from the recovery menu, but to no avail (
Thank.

Still not clear to me...
You are trying to remove RL?
Because "Region" aka CSC aka Sales Code... not affect RL
I am not at home now...
Yesterday short looked into older Firmware... I can only remember 4 CSC...
Code:
VZW
SPD
XAR
ATT
Verizon Sprint ATT and XAR ... because US market device...

Ideally, I need to change the region to the original one, then my problem will be solved.
Yes, I chose one of the four regions and after resetting GW they do not complete the first launch, more precisely, authorization is successful, but such a message pops up

[Q]SamFirmware Download ROM advise?

Hi,
so my local is UAE, when I went to download the firmwares (For removing the "modified" thing), I found two versions, LYS and XSG. both of them have a PDA number different than the other, so I didn't know what to get, then I checked my phone and found this:
Baseband version:
N7100XXDMF1
BUILD NUMBER:
JZO54K.N7100XXDME6
Then I checked the LYS and XSG and all of them end with DMC/DMB
Then I checked the United Kingdom BTU, and I found the same as LYS and XSG, with the addition of DME6 (my mobile). Which I found weird cuz I bought my phone from the UAE, and it was an international version.
What I wanna do is roll back to a previous update, run Triangle Away, reset my status to Official, then update again.
How come I have the UK's update (I updated IN THE UAE), if my phone is from the UAE? or does the Build number don't matter which country I'm in?
One more question, If I flash the ROM via Odin, what am I risking? (phone brick, app loosing, data loose...etc)
thanks

any reasons?
XSG is country code for UAE
Another way to move back to original stat
-Open kies - tool - firmware initialization - follow wizard
But this way you lose data.

but how come I have the BTU update? also LYS is also UAE, Du maybe?
If your device have BTU rom then you will get updates from btu only. Probably when you have purchased rom you may have btu version installed instead of UAE.
What you are getting by dialing *#1234#
Sent from my GT-N7100 using xda premium
if u don't have EFS backup u will end up with fake imei if u go back to DMC3 from MF1 so maybe the network wont work

Your device country code is written next to the serial number on the Retail Box.
I would suggest that you stick to the rom which belongs to your country code to avoid any problem that may be caused by loosing your EFS data.
If your are not under warranty, it does not matter which country code you are using any way.

First, on the Box I found samsung.com/fr , which means the Mobile is French. So I went to sammobile, searched France (XEF) and found the CSC and PDA, and when I run in my phone *#1234#, I get the CSC and PDA which are the exact same as the French XEF 4.1.2 update.
So that means my phone is french and I should install French Versions...Guess this is why I got the 4.1.2 update not available in the uae.
That i already said, if your device have other country rom, you can update from any place when installed country version have updates. Match all three,
Ap, cp and csc
Sammobile zip file have only pda and csc mentioned but when you extract it, tar file will have all three.
Just download. 1-2mb and explore it with unzip to find full name.

Galaxy S9 multi CSC problem

Hi guys,
I need your help: I get a Galaxy S9 with active CSC set in SMP (it is an unknown version because it's a sample).
I flashed a multi CSC firmware SM-G960F because I need an ITV (Italy) CSC on it (I want OTA and also Samsung Pay Service).
I don't know why, but when I flash the CSC it set automatically on Germany/DE Status with no chance to change it. The Active CSC remains SMP and CSC Status sets into Germany/DE.
I'm sure I've downloaded from Updato the ITV version of the firmware.
In the past years it was very simple because it need only the correct firmware of your country region to solve the problem. But now with this damn Multi CSC it is impossible!
I tried many ways and guides found here but no one solved the problem.
I wanna change it without rooting the device.
Any suggestions?
Thank you so much in advance

Apparently it's impossible to get around it because of this multi CSC no matter what firmware you flash it will not get rid of the carrier firmware on the phone.
qualcomm 9650ds, flashed a multi csc firmware, a window popped up:
SIM card change Restart your phone to configure the functions compatible with your new SIM card. This will reset the phone to its default settings and delete all data, including files and downloaded applications. NOW NO RESTAB. AND RESTART
After restarting, the correct csc has been read. (probably has something to do with the Sim card)
PS: if chosed now no, the 4g signal bar showed LTE; if yes, the bar showed 4g

For the SM-G9650DS, would you mind sharing which multi-csc firmware did you use exactly? which CSC are you on?

Can't update to Android 9.0

I just bought samsung s9 SM-G960U but can't it won't update to android 9.0 manually ! it says processing failed
I did some researches I found that it's carrier-related . Some solutions suggests that I use odin to update but I can't choose the right firmware !
In fact :
- when I try to check the csc using *#1234# it show g960usqu2are6 ( I think it's Verizon using google)
- when I log on into samsung website and enter my imei . The product info shows that my carrier type is Sprint
- when I check "about phone/service Provider SW " on my phone the first line contains TMB after G960U and the third line is TGY/TGY/TGY
I'm confused but I want to update my s9 to android 9.0 . Help me

get the firmware here
https://www.sammobile.com/firmwares/galaxy-s9/SM-G960U/VZW/download/G960USQU4CSC7/265795/
get the most recent version of Odin (i didnt source you a link for that)
open Odin on your computer
unzip the package and get your phone into download mode, connecting it to your computer. Allow drivers to install and when Odin recognizes your device by showing a random number in the port field. Then place the files in their corresponding spots in Odin paying attention to which CSC file you use as one factory resets the phone and the other simply applies the update. It is recommended to use the factory reset CSC when changing from different iterations of the Android OS. Press the start button, allow it to full run the firmware push. It will then automagically reboot (yes, automagically), and youre done.

Once a phone is unlocked, it stays that way forever. Firmware has nothing to do with a phone's locked or unlock status.

Depends how it was unlocked, seen a few members flash new firmware and the phone is SIM locked again, these unlock companies must use some modification to the firmware rather than unlocking it properly

Good to know. Wasn't aware that a phone could be unlocked with firmware alone. I guess it's a temporary overlay or something that "fakes" being unlocked?

Yea must be something that emulates the unlock somehow but once reset or flashed it's gone, always seems to be people who have bought the phone second hand unlocked, it has worked fine with their sim until they reset or flash different firmware, then it's locked again
No network on device after firmware update

Boot your Samsung Galaxy S9 or Galaxy S9 Plus
Activate then access the USB debugging mode
Sync your Samsung Galaxy S9 or Galaxy S9 Plus to your desktop PC
Download this: EFS Restorer Express
Access the application and then open the EFS-BACK.BAT file
Choose a method in order to recover the EFS via Odin

CSC Change is still possible?

Hey Guys,
Just wanted to check whether any working methods are around to change the CSC of a Note 10+
Couldn't find any guides apart from the ones which are in Note 9 Sections.
Any support on this is much appreciated!

Im also looking for a solution for this. SamKey's paid service is apparently supporting this but im unsure of the method their software uses and its a paid service. Users in Australia (like me) are having issues with RCS services through Telstra (TEL) because the Open Variant bought direct from Samsung not having the correct CSC. Some users have reported changing the CSC through SamKey successfully.
I have tried flashing with Telstra firmware but no luck.

I initially did *#272*IMEI# and was able to switch between CSC. When I switched to XAA, I was stuck and could not able to use the *#272*IMEI# anymore.. So I had XAA/XAA/ATT.. I saw many were stuck.
Found a solution that worked for me is as follows. Try at your own risk.
Downloaded the tool from
https://www.mysterious-dev.com/2020/05/changecsc-all-samsung-free-tool-android.html
and downloaded the ChangeCSC Software tool.. . watched the video couple of times.. The process lets you install custom THEME.. I was getting "Update" "Delete" and "Buy" ..
What did was
install another random theme
then went back to the program and clicked change CSC again
this time when I choose the custom theme pack, I saw the "Try now".. after that I followed the instruction to about phone->legal and clicked on CHANGE Carrier Android 10 and VOILA!!! I got that CSC change page.. I saw XAA was selected and I changed to TMB... after that "Sales& Network Code Change" and clicked ok.. .The phone restarted and saw the T-Mobile logo!!!!
I even tried the *#272*IMEI# and this time it worked and showed me the CSC screen!!!
Hope this helps anyone who is stuck...My phone now says TMB/TMB/ATT!!!

Hello,
Prior to doing the process. I used smartswitch and backed up my phone completely.. I also did factory reset the phone.. *** Since I was going to use a new method/tool, I was not sure so wanted to make sure it does not interfere with any existing account/app on the phone. Once I was able to get to the CSC screen and changed to TMB, I went back again to make sure do a factory wipe and start complete fresh out. Hope this helps. Good luck!

hmm.. don't recall if it wiped.. I already had T-Mobile sim inside.. so when I saw the CSC selection page and as soon I choose TMB it restarted and came with T-Mobile splash Page, at that point I know it worked, so before even finishing up the boot process, I rebooted in recovery and did the factory reset

I had to do the CSC changing today and it simply rebooted and displayed the new CSC logo. It was with AT&T and when I change it to TMB. I get the T-Mobile boot logo.. I was able to get back in to the device without loosing any data.. The CSC showed TMB/TMB/TMB.. But I noticed the ringer/notifications sound still remained the AT&T settings. So to answer your initial question, my phone didn't get wiped out when switching the CSC.
Thx

I have found *some* Samsung models can still change CSC via firmware flash in Odin by following these pre requisites...
- disable find my phone
- sign out of Google and samsung accounts
- developer mode .... enable oem unlock
- flash a single CSC stock firmware in odin (do not use home-csc)
- phone will be completely wjped but after first boot and running setup, CSC will be change to match new firmware
Have any one tried

Hello
I bought a used s9 a few months back. It had dual sim. In "about phone" it said G960F and was on android 9. A few days ago, I wanted to flash android 10 so I downloaded firmware for G960F, booted my phone in download mode and SURPRISE. The whole thing was in Korean and of course it was a G960N model. So I downloaded firmware for G960N this time and flashed it. Everything went perfect but when the phone booted up, It had no sim service.
I've tried everything I've found on the forums so far related to emergency calls only or no sim service.
Any kind of help would be appreciated. I have no sim service for 5 days now.
Things I've tried so far:
Flashing my phone again with android 9 stock firmware, which I can't do anymore as I've updated the bootloader lol.
Flashing custom roms
Changing csc from SKC to KOO
Flashing OXM CSC as I live in Pakistan
Flashing different modems and basebands
Nothing worked
Try flashing back a G960F android 10 firmware.

How can I do that? I always get a PIT error.
What if you don't flash the pit file?

Now I'm getting a bootloader error. Tried skipping BL but odin gave me radio error this time
So skipping each part just give an error concerning the next part?

Done all of that. No luck
OK, let's go back to beginning: you've bought the used phone. 960F never was (as factory leaving) dual sim phone.
so, let's start from the beginning:
contact the seller and ask what the hell have you bought (if it was any variant of the S9 at all.. somehow I doubt it).
2nd: write down the IMEI and serial number, and check with Samsung if this configuration ever existed (if not, what I suppose, the IMEI/sn info about the REAL model can give you a hint what have you bought).
Having the above info in hands, find the "service firmware", 5 files ROM for your device and try to flash it.
If it will not work still, I'm afraid you have two options:
1. check IMEI against stolen devices with your carrier.
2. Go to Samsung service asking for help.

Well mostly it isn't a fake mediatek phone as it will not even have a download mode.
Probably he bought a shi**ily refurbished phone with it's internals mixed from multiple versions of the s9, in the best case.(a Frankenstein variant of the S9)

I'm going to solve this mystery for both of you. The phone he bought is indeed an S9. Here in Pakistan, 'software' guys in shops can convert these to dual sim models with some z3x and Chimera f*kery.
As for why his phone isn't working - it is because the phone had a tampered IMEI to bypass local custom charges levied on all imported phones (insane charges, doubles the price of these kinda phones). Once he flashed a new image on his phone, his IMEI status would have become NG instead of OK, which prevents the phone from accessing any networks.
Solution is to visit the same 'software' guys, ask them to 'patch' the phone. It is a 5 minute process, requires root (which these phones already have).
