Samsung Galaxy Watch (SM-R800) Custom Roms? Bootloader signed? - Samsung Galaxy Watch

hi all
couldn't find information about this using google or searching here.
Useful stuff i've found:
wiki. tizen .org/Porting_Guide/Tizen_Bootup_Overview (no information about signing or checksums) [remove whitespaces]
I was wondering:
1. Can I simply flash anything via Odin and it will still boot or is there some signing going on? maybe just some "custom" packing?
2. Has any1 built tizen "from scratch" using their repos (?
3. Are there more information about the bootloader(s)? do they use u-boot? (saw that in their git repo)
Thanks a lot in advance!

1. Can I simply flash anything via Odin and it will still boot or is there some signing going on? maybe just some "custom" packing?

I suggest to choose wisely... because you can brick your device... and only bring back via USB cable for instance:

2. Has any1 built tizen "from scratch" using their repos (?

IMHO useless s h... depend what you want to achieve...
But you could use their daily Tizen 5.5 Images...
Maybe i will add later what I mean...
3. Are there more information about the bootloader(s)? do they use u-boot? (saw that in their git repo)

If you download Firmware for research... you would find sboot.bin Bootloader...

Meanwhile it seems I have progress with Rooting of Stock Firmware...
First test(s) on SM-R815U... with BSE3 Firmware...
In theory I could do this for SM-R800 too...

Wow, this is cool. Do you have access to Tizen 5.5 images? Is it usable as daily driver?

Sounds good! I'm interested into test the root for R800. Let me know if you need testers.
Thanks :good:

I am still waiting for feedback from SM-R810 user...
Here are the SM-R800 files... rooted...

Here is how I create modified rootfs.img
Code:
sdb root on
sdb push .\GearS3root\R8xxSource_su\su /media/SDCardC/Others/
sdb push .\GearS3root\R8xxSource_su\fingerprint_list.xml /media/SDCardC/Others/

sdb shell mount -t ext4 -o loop,rw /media/SDCardC/Others/rootfs.img /media/SDCardC/Others/2
sdb shell cp /media/SDCardC/Others/su /media/SDCardC/Others/2/usr/bin

sdb shell cd /
sdb shell umount /media/SDCardC/Others/2

C
Removed verityctl from end of rootfs.img... with WinHex
I am using Tizen Studio... to manipulate rootfs.img
Because I am Windows Fanboy.
Best Regards

Seems no one is interessted in testing...
I got no feedback from SM-R800 nor SM-R810 user... nor SM-R815U user...
Anyway.
I have progress about "second" write protection on rootfs.img...

WEAR OS
if it was done on the gear s, why isn't it possible to do with the galaxy watch or any others for that matter? I would rather have Wear OS instead of Tizen because of the universal capability to use on multiple platforms, plus the convenience of a plethora of apps. Samsung doesn't have versatility, or so it seems...
Is there anyone who has successfully rooted anything after the S2 and uses Wear?

Roms and Kernels

Does anyone know if the galaxy watch can flash roms and have custom OS's like on previous generations? Can it use roms made for the gear s3? What are your thoughts on the default rom with tizen 4.0? What would you want from any custom rom?
Let's start a discussion on this topic!
I am pretty sure roms from the gear s3 will not work. Also why would someone Flash an old rom on a new watch? Doesn't make any sense to me.

I was just wondering whether or not they would be similar. I've seen a phone before that could run a rom from another phone, that's why I was asking. Didn't expect much tbh
Hi all. Can anyone help me with a odin files for the first software of this watch. I am have the next problem:
Hello! Since the new software update earlier this week I am having a problem with my screen brightness setting which I have set at 8. When my watch goes into AOD mode, after the 15 second screen timeout, and then when the screen goes back on again the brightness setting is down to 3. Then I change it back to 8, the screen goes into AOD, and when the screen goes back on it is down to 3 again. Every time. Never had a problem like this before the recent software update, or on my Gear S3 for years. I turned the watch off for a few hours, and then turned it back on, but the problem persists. Has anyone else had this problem, or know how to fix it? Thanks!!!
Please can anyone hrlp me with the idin files plss

Hello Adfree.
Nice video btw. Thanks for that.
I have the exact same issue like Alejandro in the video, and the exact same model: SM-810X.
Is there any way you can provide me with the rom files for this model? I would like to give it a try, and flash the files, rather keep it in the drawer...
Much appreciated any help.
Cheers!

Root Samsung Galaxy Active Watch

Hi
Is there any method up till now to root Samsung galaxy active watch? Can someone share the procedure and relevant image file?
Thanks
1.
Combination Firmware from SM-R800 and SM-R810 are rooted Factory "Service" Firmware...
2.
In theory similar way could work... like I did with SM-R760... Gear S3.
But...
2.1 Untested with SM-R800 and SM-R810...
And
3.
My old way was limited to play with some internals... blabla Commands... little bit Backup with dd Commands...
I was never able to remount rootfs.img rw...
But today first progress. :angel:
Info here:
https://forum.xda-developers.com/showpost.php?p=80683673&postcount=797
Best Regards
P.S.:
If somebody is interested in rooting SM-R800 and/or SM-R810...
Contact me or write here or we could share knowledge about Combination Firmware and existing Root or we can proceed further with Watch Faces...

Thank you for the link, I've downloaded it.
T-Mobile service, at least the people I've spoken to here in the USA don't seem to know much about the Samsung Watch... At all.
I'll wait a bit longer for answers to questions I've sent them. If they still can't help, I'll flash it myself.
Thanks again for all your help ????
I thought I'd give T-Mobile support one more try... 3rd time lucky ? I reached some one who knows their stuff.
They pushed the update to my R805U a few minutes ago.
The update worked smoothly, busy applying the new Bixby update... Then I'll take a look around and checkout the new stuff.
However, I have no idea why the Wearable App would not get the update initially.
Thanks for the help. ??

Help for Changing CSC on Galaxy watch active 2 4g (German to french) I m french

Hello I need your help because I cannot use the 4g of my watch because of the German CSC while I live in France
SM-R825F

HELP ME PLEASE

The good news for you...
You need only OXA Region files... IMHO allready posted...
DBT and XEF is inside OXA package...
Best Regards
Thank you
I have to start at step19 #?
Please remember I have NO Crystal Ball.
But I am little bit scared why you want start with SDB...
IMHO short summary...
A
netOdin Action to flash Combination firmware to have ROOT access
B
If still alive...
SDB Action...
SDB is similar to ADB from Android world...
C
netOdin Action again...
This time with Stock Firmware

OK do you have a link to download netodin for tizen please ?
Why are you afraid that I will start directly with SDB?

thank you very much but i don't know why but odin can't watch with the watch
I cannot validate the change of csc its put an error which says that the files and in lettering only in SDB command
Maybe you know my English skills are limited... and I still have NO Crystal Ball.
So i can not smell nor see what kind of Problems you see.
I only see 2 Tools inside 1 post.
I mean it is impossible to me. If step 1 is flash 1 file with netOdin...
Please if you expect any kind of help. Give FULL details what you see on your screen...
Best "magic" is Screenshot.

Example what I have expected...
It is possible to take this Combination Firmware now for SM-R825F and SM-R825U:

Friendly user confirmed it work:
https://forum.xda-developers.com/showpost.php?p=82843789&postcount=62
This would be step 1...
Btw... few weeks ago I helped user from XEF to DBT with his SM-R825F... successfully.
So it is no Rocket Science. :angel:
Best Regards
hello I understood the procedure now and I found a video that explains well I have a problem with the COMBINATION-FT40_R825USQU1ASL2.tar which failed at the end so I rebooted with that the AP, BL, CSC R825FXXU1ASI7_Tizen no problem . So I don't understand why the COMBINATION-FT40_R825USQU1ASL2.tar failed
IMHO I wrote few times in the other Thread, why "failed"...
IGNORE Error, if Watch booting proper to Firmware...
Reason is additional file/folder...
Code:
meta-data/1.mf
Btw, this is why I have removed this... and posted...
Now you can proceed with SDB...
Please try to read Instructions... IMHO all hints given how to do...
Good Luck.
Best Regards
Okay so despite the failed and the watch that does not restart I restart the watch myself and proceed to change CSC via sbd.?
Best regards
Yes.
If nothing exploded and Watch boot into Tizen OS... so you can click around and find your IP address after connecting to WiFi...
Feel free to click around this thread... you are not the only one... not the first and maybe not the last... here for instance Screenshot of netOdin:
https://forum.xda-developers.com/showpost.php?p=82347797&postcount=32
IMHO only to need reading twice... or maybe more then 2 times or 3 or again.
Nearly all problems allready described in this thread... IMHO.

This TAR file is inside this 7Zip package:
Code:
ownRISK-FT40_R825USQU1ASL2_repair_v1.[B]7z[/B]
Differnce to the other files, I was toooo lazy to created the MD5 Hash,,,
So maybe better you use the allready known Combination Firmware... because MD5 is good for Selfcheck...
Hello I have a R825F

Excuse me for my English but I speak very little (which makes my understanding more difficult). I speak spanish.
Short version: I´m in Argentina with an Active 2 SM-825U (Tizen 5.5.0.2 / Build Number: R825USQU1CUD1 ) that cannot see the movil network.
Company says I should have bought SM-825 ( without U , my fault ) but confused me saying american models. After my bought said Mexico and Canada models )
My Questions:
1- What must I specific do ? Can I fix that only changing the CSC code to ARO , MXO or XAC ?
I not finding or not knowing what combination files I must use.
Don´t match last 4 characters: https://easy-firmware.com/index.php?a=downloads&b=folder&id=47818
2- I´d be interested to know if I can use SM-R820 or SM-R825 combination files or would that kill the watch ?
I´ve reached to establish communication between the watch and NetOdin but I´ve stopped there for not knowing the above.
From already, thank you very much ! Sincerely.... Eduardo.

Changing CSC SM-R825F from Hungary to UK

Hi!
I've been lurking this forum for a while and am really eager to change my Galaxy Watch Active 2 CSC from Hungary to UK to make Samsung Pay work. I have a Curve card specially for this but I've been too afraid to do it because I'm afraid I will lose the 4G functionality of my Hungarian Telekom provider.
Right now my watch is set up with Telekom and has 4G set up as esim.
My big question is if I change my CSC to UK, will I lose the 4G functionality? Will I still be able to connect to my Hungarian esim account?
Please let me know, any information is greatly appreciated!!

I did it, Samsung Pay worked, but it doesn't connect to the Telekom network. Then I also made the mistake of wanting to re-register the eSIM, but it no longer allows me to try any available ROM. Now I should get the factory Telekom ROM, but I have no idea where it comes from. It sucks. Very big sucks.
Theory.
ESIM is activated and work. :good:
IMHO eSIM profile will not be erased.
So IMHO eSIM is lowest problem.
But SPay chance 50 / 50...
Maybe your plan will NOT work for Samsung Pay...
Best Regards
Hi Adfree,
First of all I want to thank you for your reply and all the work you are doing for this community. You are by far THE Galaxy watch expert. You're always commenting constructive feedback to people.
Everywhere I see your comments and helping out people. A big THANK YOU!
I will try to change the CSC, even though I'm a big newbie to this.
One last question: will I be able to revert the watch to its original state if it turns out it doesn't work? With that I mean original firmware that it came with?

To increase your chance to get Original Status... my suggestion:
A
Check Firmware infos on your device to be 99,9 % sure what you need...
Type like you would call someone:
Code:
*#1234#
Then you see all relevant infos to find your Firmware...
B
For Orignal Settings... my suggestion with SDB Tool from here:
https://forum.xda-developers.com/showpost.php?p=74585286&postcount=330
B.1
Check Bootloader Version sboot.bin
Code:
cat /proc/cmdline
B.2
Check active CSC
Code:
cat /csa/csc/csc-active-customer.inf
B.3
Check Product Code
Code:
cat /csa/imei/prodcode.dat
You can save these infos with Screenshot or by Copy and Paste Text only... with right Mouse Button.
Best Regards
