Hello friends,
I'm from Brazil and I bought a LTE Galaxy Watch in Germany, exactly the same version (Sm-R805F) used in Brazil. However when I went to my mobile company to activate the e-sim it was not possible. When the system ask to read a QR code, in the mobile networks' activation process, a message of error appears ("It's not possible to conect this mobile"). Does anyone know why and how to fix it?
Can you check this Code...
Code:
*#1234#
Seems DIFFERENT Software crap exists... so different Profiles...
Code:
OXX
OXA
Check your CSC ...
OXA could be inside German Version... and OXX is maybe for Brazil...
Best Regards

Thank you very much!
I did it and the CSC is OXA (German version).
How can I change it to OXX?
PS: I did as they recomended here (https://forum.xda-developers.com/smartwatch/gear-s3/guide-how-to-change-gear-s3-r760-csc-t3784226 ) but theres no Brazilian code nor OXX.
OXX and OXA are """group"""
OXA contains minimum DBT CSC... for Germany
You can NOT change from OXA to OXX... because the config files not inside...
Your Link shows only way to change existing CSC inside flashed CSC file...
Example...
I have Firmware files... from OXX region...
Code:
CSC_[B]OXX[/B]_R805FOXX1BRI4_usr.tar.md5
You can unpack and extract with 7Zip... csc.img file.
Folder preconfig have 8 folderS with 7 CSC... DEF means Default IMHO...
Code:
BRI
TGY
VAU
XNZ
XSA
XSG
XSP
XSP is Singapore...
For the others I am tooo lazy... forgotten... use Google...
I have NO idea if it is an good idea to try to flash with netOdin such CSC files... or complete Firmware of OXX region.
Samsungs funny Security...
Best Regards
Edit 1.
I have tried to identify Brzil via Google search...
For me it looks no CSC inside for Brazil...
I have NO idea if SM-R805F is for Brazil market...
Edit 2.
Okidoki... Google search leads to this:
https://www.samsung.com/br/support/model/SM-R805FZSAZVV/
So looks like exists for Brazil... and you can see Sales Code ZVV it is in Product Code...
Code:
SM-R805FZSA[B]ZVV[/B]
IMHO 3 region groups... OXX OXA and ?
Firmware for Brazil seems not leaked... with ZVV inside...
Edit 3.
Firmware for SM-R805F for Brazil looks like this:
Code:
R805FXXU1CRK7/R805F[B]OWO[/B]1CRK7/R805FXXU1CRK7
So OWO is Region Code... for Brazil...
IMHO OWO package have ZVV Sales Code/CSC inside... for Brazil.
Edit 4.
My fault...
Code:
R805FXXU1DSC7_Tizen_4File_Multi CSC ([B]OWO[/B]).rar
Leaked and available...
But still no idea if this helps you... because dangerous to flash... Sams..g Security could prevent success...

Hi,
Can you list the available CSC's within the OWO version ?
I wasn't able to find it for download to check by myself..
@Nocturney
Region OWO Firmware contains these CSC:
Code:
COM
ZTA
ZTO
ZVV

I've been reading the post, but I'm a little lost. I do not know what to do. I have a R815 Vodafone Germany version, and I want to activate it for movistar Spain, but I receive the error "It's not possible to conect this mobile". The data of my watch are the following:
AP: R815FXXU1ARH5
CP: R815FXXU1ARH5
CSC: R815FOXA1ARH5
With the SDB utility I have accessed a hidden menu on the watch and I changed the original CSC VD2 to XEC, or at least I thought so ... I think VD2 is Vodafone Germany, and XEC is Movistar Spain (the company that I have on my mobile phone). Samsung Pay works, but LTE is impossible to configure ("It's not possible to conect this mobile")
It is possible to get a different firmware and flash it?... or how can I get to configure an esim (lte) from movistar españa?

Hey guys, I was reading this post and I have a problem a little different of you.
I bought a Galaxy Watch from The USA, LTE version (R805U) but I live in Brazil, I went to the phone company (VIVO) to try able the LTE (eSim) function but they said to me that it is impossible because only the R805F works here. My question is. Can I change the firmeware from 805U to 805F and it will works LTE here ?

Is not to you to do'it...
You need to call the operatório, in this case, Movistar and subscribe for the service and they activate the eSim...

Hi had same problem
Hello mate
I bought Samsung Galaxy watch when I was on holidays in Greece as in UK the LTE version was only with contract on EE. As I'm using Vodafone UK, I got the Qr Code for the esim but Samsung neither Vodafone could help me to make it work. Finally I make It work but my self, because my Samsung Galaxy watch is from Greek region I try to activate my Vodafone uk esim with a Greek sim network in my mobile device and it's worked perfectly, even when I put back my Vodafone uk sin on my mobile.
Hope that helps you.

Hi, could you elaborate on how you did that? I want to buy the silver LTE version from Hong Kong because that colour is not sold in Singapore, and it would be great if I could get the LTE working.

Hi All,
I have read that to debrand a Samsung Galaxy S20 phone (mine is SM-G981B) you can't just do a straight flash with Odin using debranded firmware and that you instead need to first change the CSC using SamKey. However my issue is that the CSC for the carrier my phone is currently on (United Kingdom EE) seems to be the same as debranded firmware (United Kingdom BTU). You can see here: sammobile.com/samsung/galaxy-s20/firmware/SM-G981B/BTU they both have the same CSC (G981BOXM1ATCT).
I also came across this guide: samsungsfour.com/tutorials/how-to-install-stock-rom-on-galaxy-s20-s20-plus-s20-ultra-s20-5g.html for debranding, however without any other sources to back it up, I am a bit reluctant to try it out in case it causes any issues.
Any help with this would be greatly appreciated thanks.

Mate, all you need to do is change the csc to BTU in order to debrand. EVR and BTU csc are part of the same multi csc, however change your csc to BTU if you do not want any carrier bloatware or boot image etc.
So the only way to debrand is to use samkey? There is not a free/not payed alternative?

Denzel09, you can buy a single SamKey credit on eBay for £2.25 just to let you know. Search for SamKey, sort by cheapest and set "Item Location" to Worldwide.
Hello community!
I recently bought a Samsung Galaxy S20+ (SM-G985F) which is carrier branded and sim locked. I am looking to remove the carrier branding by using a unbranded firmware. I am trying to find an unbranded firmware that will not affect the functionalities of the phone ( VoLTE, VoWiFi etc..) . Would this be done by finding a firmware with same PDA but different CSC?
Current Branded Firmware:
Version G985FXXU3ATG4 / G985FOWA3ATG4 / G985FXXU3ATG4
Product Code: PGU
Would this firmware work?
Product code LUX
PDA G985FXXU3ATG4
CSC G985FOXM3ATG9
Thanks in advance for your help!
@servenaya
if you have a sim card of Guatemala and you want to keep VoLTE, VoWiFi etc.. for this country
install Version PDA G985FXXU3ATG4-CSC G985FOXM3ATG9
and change your CSC to GTO ( with préconfiguration for TIGO_CGU , PCW_PA and Claro_DR )
LUX have only préconfiguration for Luxemburg ( Proximus , POST , Tango , Telenet , Orange B and LUX )
regards

@yakapa40, thank you! This information is very helpful. I do have a Claro Guatemalan sim and even though the carrier does not support VoLTE, or VoWifi, I would like to keep this features in case they implement them in the future. I did find a firmware with the recommended PDA and CSC (Country South East Europe, Product code: SEE, PDA: G985FXXU3ATG4, CSS: G985FOXM3ATG9). Would this firmware work? From what understand, I would have to first flash this firmware, then change de CSC with Samkey to GTO and lastly, factory restore the phone. Is this correct?
Also, would you recommend using Samkey to perform a carrier unlock before changing the CSC or could I do it later on? I read that Samkey only works for phones that dont ask for unlock code. Mine does ask for a code when I insert another carrier's sim.
Thanks in advance for your help!
save all your data
install new firmware
you have a free apk here to change the CSC:

@yakapa40 Thank you for your help. You are extremely knowledgeable on this topic! To be honest, I just realize how little I know about flashing even though I've been doing it since 2012. I feel like I understand firmware flashing less than I did before.
I just have a last question. If I flash the firmware with a CSC NEE, and than do the CSC change to GTO, which CSC will be used for future OTA updates? What I mean is, if there is a new NEE firmware will I get it, or will I have to wait for a new GTO update? Sorry, I am little confused with all of this.
G985F OXM is a multi CSC so if you flash the firmware with a CSC NEE , you will get XEF CSC by default
, and when you change to GTO you will get GTO OTA updates

@yakapa40, I was finally able to flash the phone. I followed the steps and got the GTO CSC and the unbranded firmware working! Thank you for helping me throughout the whole process. The only down side was that I still lost the VoLTE and VoWifi options. When I look at the Sim Card Status menu, the IMS registration Status is "not registered". :crying:
Hi guys,

Hi,
Its the bluetooth version (sm-820)
Originally it had the german or dutch csc, and on the newest firmware.
Hi Guys,
I got a F936N which is Korean. I want to change it to OXM since I am in the UAE. 5G is not working on the phone and I got some weird carrier settings for Korea.
I tried using the SamFw_Tool to change it to a CSC and also tried flashing the OXM firmware via patched Odin, it is failing.
One thing to note is that my device has 1 SIM and 1 e-SIM. The devices here in the UAE are 2 physical SIMS. Not sure if that would create a challenge. I just need 1 SIM to work.
Is there anything else I could try?
Thanks.
Bump. I have a OXM CSC tablet that I Want to change to a US CSC
Hi, I have the same issue. I got a F936N which is Korean and I want to change it to OXM as I am in India. Someone please help.
Any work around to use 5G in India ?
