R845F OTA issue after CSC change - Samsung Galaxy Watch 3

Hi
I change CSC on my Galaxy Watch3 few months ago to get Samsung pay working. It was originally Indian version and changed it to somewhere in Europe.
I cannot get any OTA after that. When I check software update it says the watch is on the latest version which is not true.
Here is the current version info: R845FXXU1CTJ5/R845FOXA1CTJ5/R845USQU1ATF2
Kindly guide me what changes should I make to fix the OTA problem, or get the latest firmware any other way.
Thanks

Hello everyone, I did a lot of reading on this forum but I am not able to understand how to make my watch work with OTA. Should I change CSC back to the original one? My watch is from India.

Code:
R845FXXU1CTJ5/R845FOXA1CTJ5/R845FXXU1CTJ5
Can you compare your text string with this?
To be 100 % sure enter this Code:
*#1234#
This shows all usefull infos about your Firmware...
R845USQU1ATF2
Because this is for sure wrong... for FOTA update chain.
Btw.
You have Link to CTJ5 Firmware?
If yes. Please Link.
Otherwise I will upload...
Best Regards

Hi @adfree I have CTJ5 downloaded from the link you shared.

Please from Watch SM-R845F...
Thanx in advance.

I am surprised how dumb have I got. LOL
Here it is from the watch @adfree :
AP: R845FXXU1CTJ5
CP: R845USQU1ATF2
CSC: R845FOXA1CTJ5
Thanks again! Appreciate your help!!

Just to be 100% correct. Here is screenshot from the watch.

CP aka Modem aka Baseband is not correct.
Try to flash only this file with netOdin:
Code:
CP_R845FXXU1CTJ5_CL1598457_QB17229736_SIGNED.tar.md5
If FOTA chain is then fixed... depend if your Bootloader sboot.bin is valid CTJ5...
Best Regards

Amazing, thanks a lot @adfree. Flashing CP fixed the issue and now I can update the watch.
I am still wondering which is the best region to have all the health features unlocked. Do you have any preference in this regard?
Now I am at this version:
If I want to change CSC again, will I have to perform all the steps:
1. Install combination firmware.
2. sdb pull, change csc, push.
3. Install AP, CP, CSC etc?
-
Thanks again

Okay, just found out that I need my phone and watch to be in the same region for Samsung Health Monitor app. My phone and watch both are from India. I changed region on watch to get Samsung Pay when it was not launched in India. Now I am getting weird issues. Can I change the region back to India ?
Thanks for all the help you are providing.

IMHO INS CSC is inside other package...
http://fota-cloud-dn.ospserver.net/firmware/INS/SM-R845F/version.xml
R845FXXU1EUK2/R845FOXX1EUK2/R845FXXU1EUK2
WARNING!
No newer Leaks available...
So you have trouble to reach again EUK2 via FOTA... because only old Firmware Versions leaked...
And Bootloader sboot.bin is not updated... so you MIX odl and new stuff...
= invalid FOTA chain
This is at the moment NOT fixible...
Best Regards

Understood! So I'll remain in Europe. I found a modded version of Samsung health monitor somewhere and used it to get ECG and BP monitoring working.
Thanks!!

Gear VR - Network Error

I've searched all over, and can't find a solution to my problem.
Finally received my Gear VR, plugged in my phone, need to take it out to install VR apps, network error.
Some background:
- I'm from South Africa, mobile operator Vodacom. Vodacom has bloat, which sucks, so I install the UK BTU rom from sammobile.
- After I received the error, I reinstalled the Vodacom version from sammobile, no luck.
- Factory reset, no luck.
- No apps of any kind (facebook or otherwise) are disabled on the phone.
Any other suggestions?

Did you make sure it installed the correct CSC after updating the firmware to the BTU-version? You need to boot into recovery after flashing in order to properly install the CSC. Download Phone Info Samsung from the play store and check out which CSC you are using after flashing.

Right, so I did and found this.
Is the CSC on the second pic supposed to be blank?

So reflashed the ROM and the CSC, and seem to be back up and running. Thanks for the help.
If missing CSC is a problem
you don't need to reflash.
and if you have root, no need to add whole CSC
Don't even need to reboot the device.
just add one file
check my post here

Firmware Country Variants A715F/DS

Hello,
Sorry if this has been asked, but i can't seem to find the same question anywhere else.
I have a Samsung Galaxy A715F/DS (vietnam) branded International Unlocked Phone, but i live in the USA... I see many firmware updates for this phone at SamMobile site, Is there a firmware i can use that will allow the phone to be more compatible for the USA use? and is it possible to flash a different country firmware with the same model number on this phone instead of using the Vietnam version? i'm well familiar with flashing firmwares, i'm just not familiar with different county firmware updates. Help please any suggestion or advice would be appreciative. Thank you

And what exactly is "the USA use"? You use it sideways over there?
Have the same version of the phone with XME (Malaysia) firmware installed. Try out the firmware TGY (Hong Kong) and no problem encounter. The only different is that different countries have their own type of software packages. Hope this help.

Samsung apps are based on the country code of your firmware. I'm interested in changing Samsung Pay so MST works because right now I am on UAE firmware and MST did not work when registering with the UAE version of the app. My rewards/offers for SPay are also in their currency, not US, so for now I am using Google Pay because I don't want to wipe my phone and try a bunch of different firmwares. Samsung's country codes make all this very complicated.
If someone has found a firmware compatible with USA Samsung Pay and US Samsung apps, please share.
Good day! Could somebody help me with my A715F/DS? After I updated via OTA, it bootloops and all other firmware from SamMobile is not working though ODIN - PASS but after reboot, the bootloop issue still exist. I attached all the firmware I used to flash via ODIN.

Never get an update on GW3 - R850

Current Version is : R850XXU1ATF3/R850OXA1ATF3
Originally from Korean Region and replaced it with XSP (Singapore) just to get SPay. But never received any update since then. Everytime I check, it always says "Your Software is Up To Date".
According to the instruction last time changing the region will not have any impact on the future product update.
Today, I just checked : https://doc.samsungmobile.com/SM-R850/XSP/doc.html and apparently had some updates and most recently with : R850XXU1BUD1.
What did I do wrong? And how do I get the latest update now? and if manually update, where can I get the file R850XXU1BUD1 from?

ATF3 is simple wrong for XSP CSC... not valid for chain of trust/FOTA crap
http://fota-cloud-dn.ospserver.net/firmware/XSP/SM-R850/version.xml
ATF6 is inside chain...

I am for now to lazy to search for you... maybe later more motivation...

No problem,
But how do I determine which firmware files are correct? I had the impression that R850XXU1ATF3 would be the correct one.
I'm currently trying to download from : https://androidfilehost.com/?fid=2188818919693790187
File Name : R850XXU1BUAB_Tizen_3File_CSC (OXA).EF_53e0ae776a.zip​
Hope it's the correct one.
Hi,
Just to give you an update that I was able to succesfully updated to
R850XXU1BUAB_Tizen_3File_CSC (OXA).EF_53e0ae776a.zip​
Do you reckon that I would be able to do a software update now? The latest should be R850XXU1BUD1 (as shown from : https://doc.samsungmobile.com/SM-R850/XSP/doc.html) but mine is still
AP: R850XXU1BUA8
CSC : R850OXA1BUA8
Country : XSP (Singapore)
Thanks, a very curious fellow here. Any help is greatly appreciated.

Hey adfree,
Since you seem to be very knowledgeable and I've been waiting for you as well to give me some hint.
Nothing seem to work.
Currently, I have R850XXU1BUA8/R850OXA1BUA8 ==> it's an EIGHT not a B
I understand that this may not be valid for the OTA in : http://fota-cloud-dn.ospserver.net/firmware/XSP/SM-R850/version.xml
I'm trying to get the version that can be inside the chain, but I can' tseem to find it. Would you be able to direct me to the right place to download?
Thanks a bunch, great appreciate your help

Question Firmware & CSC quick question

Greetings,
I have an SM-G998B/DS, which was bought closed carrier unlocked, but with a firmware from Vodafone (Comes with 3 Vodafone apps which are easy to uninstall). Also the Active CSC code = ATL.
I am from Spain, so I wanted to flash the firmware with the one which says PHE, thi sone in particular

Fast download latest Samsung Galaxy S21 Ultra firmware SM-G998B from Spain with G998BXXS3AUHD and Android version 11
www.sammobile.com
File downloaded:
G998BXXS3AUHD_G998BOXM3AUHB_PHE.zip
Thing is that I flashed without issues, but I still see that Vodafone apps gets installed and in the Phone Info APP still says ATL
My understanding is that by flashing with PHE, the firmware would not be tied to any carrier in particular? And it should show as PHE in the phone INFO app?
Also, I always have seen the CSC blank, even before flashing, except for the "Active CSC". Is that normal?
Thanks in advance!
Out of curiosity, Whats your software provider software version?
I.e. TGY/TGY,TGY/BRI
Greetings,
I am attaching a screenshot.
Thanks!

Hi
Changing the active CSC is not as easy as it use to be, before just flashing the correct firmware and booting the phone with the right SIM was enough
There are a couple of options using a dialer code , myself i used that method to change from GTO to PHE , I see you have the latest firmware I do not think they will work anymore , you can try if you want check here
If that does not work your only option without root is samkey ( pay)
Thanks for the reply!
I think I will just leave as it is. I can survive with 3 additional apps which I can uninstall.
Thanks again

Question Stuck at EUX CSC, Even Odin doesn't change it

I recently got my phone serviced from Samsung and ever since the device is at EUX firmware. I tried flashing INU , DBT and XSA firmware, all these are showing EUX. Only exception is XID (Indonesian Firmware).
I was trying to get to XSA (Australia)

Firmware but it never changes to that.
After this if I install DBT or INU with home csc it will still be at EUX even after factory reset!
Any info would be great!!

the only way is via samkey , buy credit and change csc .
but u must be on EUX not XID if u want to use samkey.
XID have native call record , but late late to get every software update.
Okay, I'm waiting for the credit atm
