Hi everyone,

I think this thread is the most related topic to the problem I have with my GWA2 with some minor differences. I hope someone could help me.

I'm in Canada and I have purchased a "GWA2 40mm LTE Unlocked" from US, the model is R835U. My career supports LTE ad eSim, but I get the "There isn't any plan available in your country, Contact Samsung..." error in the Wearable app. So it means the device is GeoLocked. Now my questions are:

1- Can I Geo unlock it to use it in Canada by changing the CSC?

2- I see many CSC change instructions are for R825F/R835

F

, not R835

U

. Is there any difference or it's just the firmware?

3- What firmware files should I download to install on it to have LTE working in Canada Region? The watch is Tizen 5.5.0.1 and I read some methods are not working on v5.

Model: SM-R835U

Tizen: 5.5.0.1

Software: R835USQU1BTJ6

I appreciate any help to fix the problem. I should decide in the next two days to keep the watch or return it to US, I strongly prefer to keep it, because that color is not being sold anymore in Canada. Thanks
[Samsung Galaxy Watch] equlizer:
So just to be 100% sure here. I have those too.

I flash combination (newest one) of U

flash the CSC from the newest U firmware or the W firmware i want to be on?

pull, edit, push 2 files.

flash 4 firmware files of the newest W firmware and reboot?
[Samsung Galaxy Watch] Mithos11:
For you model I changed csc with a other operation, but I don't know how to change from U to W.
[Samsung Galaxy Watch] equlizer:
Are you using the original firmware for the watch after flashing the combination and changing that CSC to get you region change?

What other operation did you use to change CSC?

I must be missing a step somewhere. I downloaded the newest U combination and regular firmware and the latest W firmware. I should have everything.

For 805 and 815 I used this post

https://xdaforums.com/smartwatch/galaxy-watch/sm-r805f-csc-change-howto-esim-rsp-v2-x-t3848292

But in your case you have to use tizen 4.0.0.6.

After combination firmware I installed original firmware
[Samsung Galaxy Watch] equlizer:
So i need the tizen 4.0.0.6 815U 4 file firmware and combination firmware instead of the latest? Then after that download the latest and install?

@ SM-R825FS user(s) :angel:

Still IMHO not good to change something in netOdin

My opinion... based on problems for Gear S3...

https://xdaforums.com/showpost.php?p=75135544&postcount=27

Still Question if Bootloader sboot.bin is written from SM-R825US... or skipped.

:confused:

Skipped means not visible in netOdin Log... because handled by sboot.bin inside device...

But visble via Odin Mode aka Download Mode... or simple visible infos...

As example... Engineer sboot Bootloader looks total differnt as User sboot from Stock Firmware...

Example from SM-R815U:

Okidoki...

A

Now I know Bootloader sboot.bin is not overwritten with SM-R825US...

It is ignored... skipped...

B

netOdin Log...

Reason for Fail is additional Folder:

meta-data

With file.

1.mf

No idea... maybe Watermark or Cert or Signature or... what ever... not needed for Firmware.

C

Stock Firmware contains also Test file... but you need only:

BL_R825FXXU1ASI7_usr.tar.md5
AP_R825FXXU1ASI7_usr.tar.md5
CP_R825FXXU1ASI7_CL1263214_QB13943174_SIGNED.tar.md5
CSC_OXA_R825FOXA1ASI7_usr.tar.md5

This file you can ignore:

Worked for me with BTU CSC

So it worked fine for me. I followed all the steps. I got a little bit concerned when I got failed after AP upload, and then when I saw weird icons in the watch, but I completed all the steps and it worked fine. I used BTU as i am in the UK and now I am waiting for network set up. I couldn't do it before. It also updated to the latest software ok.

Thanks everyone involved in that.
[Samsung Galaxy Watch] Daaraen:
I purchased a german SM-R825F watch model, but I want to use it with LTE in Austria. I phoned with the Samsung support a few days ago, telling that I can't setup the LTE connection due to the german model used in Austria. Samsung support confirmed to me, that this year a update will rollout which allows all European watches to set up LTE without country restriction. This happened also to the Galaxy Watch (not sure if it was this model) and will also happen to the Active 2 via software update.

As I read several times, the flashing procedure can brick the watch, so it makes sense to wait for the official unlocking - and if it does not happen I can still try to flash it.

What I couldn't find in all these threads, is there a possibility to recover a bricked Active 2 without opening the watch?

[Samsung Galaxy Watch] adfree:
Use Tool 7Zip to unpack and extract files from csc.img...

Then you will see. You can only use "Script" files which are inside CSC Firmware File...

NOT dream...

IMHO SM-R805W is Canadian device with limited CSC text/script files inside...

Exactly 1

XAC

So you can choose between XAC or XAC or you can enter XAC as CSC...

[Samsung Galaxy Watch] djtd23:
I have a similar problem that it seems you've solved. I have a R825F, I ran the process described at the start of this thread successfully, changed CSC to TIM (my esim provider in Italy) via sdb commands and then flashed the US Firmware from first post. Everything went well and have since updated software OTA. I cannot load the ESIM profile and I think it is because I have the latest US firmware AP: R825FXXU1CUA5 CP: R825FXXU1CUA5 CSC: R825FOXA1CUA5

In the About watch menu - Software version it says R825FXXU1CUA5 SM-R825USSVNEE.

I don't really care about any of the other features just want to get LTE working here in Italy.

Can you describe how you got yours to take the Italian Esim plan?

Thanks @adfree

i followed the original instructions at the start of the thread firstly installing below combination firmware, Stock CSC via NetOdin3 then the SDBstarterKidv1 root CSC file

changes.

COMBINATION-FT40_R825USQU1ASL2.tar

After CSC files updated i installed the below stock firmware files;

AP_R825FXXU1BTI9_usr.tar.md5

BL_R825FXXU1BTI9_usr.tar.md5

CP_R825FXXU1BTI9_CL1701429_QB16973615_SIGNED.tar.md5

CSC_OXA_R825FOXA1BTI9_usr.tar.md5

At this stage everything worked fine, installation was successful and the boot information wasn't shown on the screen... but the FOTA update wouldn't work via the mobile app so I decided to try reset and install the FOTA update via the watch without connecting to the mobile or app..

Now for the problem... when it came to following the initial power on setup instructions it would hang/lock up on the PIN confirmation screen - no matter what i try i couldn't get passed the PIN number process..

i thought maybe the watch was faulty so i installed the R825FXXU1BTI9 again on another device but it locked up same at the PIN stage again.

At this point i decided it must be the firmware files so decided to start again and go back to installing the earlier firmware following the whole CSC rooting instructions again as below;

COMBINATION-FT40_R825USQU1ASL2.tar > stock CSC file > rooting files (BTU) > then R825FXXU1ASI7_Tizen_4File_CSC (OXA)

from this point i now get the boot information... and everything else works ok apart from the FOTA update still not working!! :(
[Samsung Galaxy Watch] adfree:
sboot.bin from Engineer is not valid so FOTA fail...

Will check if I find newer Stock firmware...

Hi all,

First thanks for all heartful works on that topic.

I follow the guide i already can use "COMBINATION-FT55_R825USQU1AUA4_clean.zip" successfully and upgrade to near lastest TIZEN 5.5 firmware (R825FXXU1CUA5). However it can not use FOTA like you mention in topic. (I live in VN with CSC XXV, change to USA XAR).

Because i can switch between Tizen 4 and Tizen 5 sucessfully two time, so i try to experiment to solve FOTA problem. However, i make some fatal mistake. After flash Combination_TIZEN_4, i forgot to flash new CSC from stock firmware. Watch still can boot and go to wireless download mode, but when flash with NetOdin3 it will fail all type of flashing.

+ In NetOdin: it say "RQT read fail" follow by "RQT write fail" and failed

+ In watch wireless download mode: it say "wireless-tool crash occurs")

Watch can still run combination_tizen_4_os and can be sdb via wifi with root account. Did you experience any thing like that and found out ways to fix wireless flash ?

We are in lockdown so can not bring it to Samsung Service Center. If anything you can guess please share with me. Thanks much.
