You will need to connect to the JTAG pins on the watch for jtag flash. To unbrick your device.
Try to use NetOdin first and then flash recovery and kernel again and then reinstall OS.

Hi,
I have a big problema in my gear S3. I am installed a rom default and then installed this rom. My gear don´t work. Is posible that you say me step by step how install the rom from zero.
Thanks.

@Apirola2
Step 1.
Identify your CORRECT Model Name...
You have SM-R760 OR SM-R770 or something else?
Please, NOT post again something like this:
https://forum.xda-developers.com/showpost.php?p=72332829&postcount=29
Best Regards

It seems APJF is too old...
As we have the problem with Downgrade Bootloader...
BQC5 is not yet available for free... as it seems.
But on paid sites you can find it for SM-R770...
So it is leaked. :good:
WARNING!
Combination Firmware BQC2 is available, BUT this is Service/Factory Firmware...
This could lead to other bigger problems... like disabled wifi...
Then only USB cable... can flash this device.
Best Regards

If it is stuck at samsung bootlogo .. go to download mode ( press power button for 5 seconds, when on the screen it says rebooting, press power button 3 times and then select download mode ( wifi ) then go to your computer and select network ( it should say Gear3-xx-xx ) , it will be an adhoc network. now wait for few seconds on the watch you will get msgs like unable to connect to 192.x.x.x but after 10-30 sec it will say connected to 192.x.x.x. Then open NetOdin and select your previous rom that you had. Or do an ugrade to a newer rom.

Will this work if I have firmware R770xxxu2aqc? I would like to flash it to stock (I'm in the US). Google doesn't bring up much of the Classic version only for the Frontier. And I'm a little confused on the installation process. Thank you for your help.

Will this work if I have firmware R770xxxu2aqc?

Really 3 XXX like adult content or better the movie with Vin Diesel...
And no joke... the red marked 2 means... this Firmware is tooooo old... be carefully.
Samsung integrated Rollback Prevention... "Downgrade Protection"
No idea yet, which is latest R770 Firmware public and free available... but you need an 2 instead 1...
Code:
R770XXU[B][COLOR="Red"]1[/COLOR][/B]APJF

Jajaja! So funny. And yes that's what my gear says. Oh ok. I guess I will have to wait for the future and see if anybody does anything with the Gear S3 Classic. So sad. Thank you for your help.

Gear S2 have Live Demo Units...
SM-R720X
SM-R732X
But I never heard of Live Demo Units from Gear S3... in theory not impossible.
To check it could be enough to enter download mode... and check if you see:
SM-R770
or
SM-R770X
BQC5 is also leaked for SM-R770...
R770XXU2BQC5_R770OXA2BQC5_OXA
Code:
AP_R770XXU2BQC5_usr.tar
BL_R770XXU2BQC5_usr.tar
CSC_OXA_R770OXA2BQC5_usr.tar
I can only not remember, if somebody offer this file for free download...
Best Regards

What's new in this version? Is the pay available? Thanks

Hey Guys, I really hope someone's going to know how to fix my problem.
I was an idiot d*ckhead, I didn't read the risks of downgrade before I downloaded this ROM and I fleshed it. I'm not a newbie, but of course it has been bricked. Bootloop and disabled wifi...
Is there any possible way to reanimate my watch (a method for usb flashing or anything) or what should I do?
I was thinking about to give it to Samsung and saying it received an OTA and just died during the update...
Please if anyone can help me, just send me a PM. I've tried to look for those "paying" websites, I wouldn't mind that either.
Thank you so much

@xedamen
If you want, you can contact me via PM...
Meanwhile you could click trough this Thread...
https://forum.xda-developers.com/gear-s3/how-to/gear-s3-android-wear-port-wip-t3584588
Focus on find Service Manual for SM-R770... you can also look into SM-R760 Manual...
Few posts are Pinout related... for soldering wires...
Caution, if you never solder wires to something really tiny... better not try with expensive Gear S3...
Problem... also minimum 1 user failed to connect USB cable to SM-R760...
And I can NOT remember any SM-R770 feedback...

... i found info how to get my S3 back to live again. If you have the same problems with your (bricked) S3 then go to download wirelessly mode en as soon as you see the flower then push the power button 2 seconds en let it go for 1 second, than push it again for 2 seconds en let it go for one and so on til you get him in to download wirelessly mode. May take some attempts but it saves my ass a few times.

Okay, so it seems that this firmware has root access enabled by default, as "su" is locate in /bin/su of the rootfs.img. This means that we can pull images from the device and flash custom images once we figure out how to either port Android Wear over or build TWRP!

I have a ZTO S3 Classic, is it possible to change to XSA flashing this file? I wondering because here in Brazil we have SPay on our Smartphones but not on the Smartwatches yet

@dxzdxz1
Please be carefully...
At the moment I saw 2 devices "die"...
Better wait, if repair is possible "at home" in worst case scenario...
Otherwise you can brick your Gear Wearable... then WiFi not work to connect with device... Odin...
Only as hint.
OWN risk!

Watches die after downgrade Tizen version.
Don't flashing APK3, APK7.
Download only same version BQC2 non-combination or any combination firmware.

Code:
Watches die after downgrade Tizen version.
Don't flashing APK3, APK7.

So it looks like again sboot Bootloader is not downgradable... except Combination files downgrade Bootloader (sboot.bin)...
Hmmmm.
Any idea how to detect Bootloader Version on Wearables?
On Tizen Mobile I can see it in Logfiles...
Best Regards

I can only find BQC5 firmware to download (for free only the APK6 and APJF)
I imagine that BQC5 will work in this case, but could you confirm to me?
About the CSC reset, after make this CSC Reset thing, would be possible to change my CSC region? It would be awesome if we could change to XSA or any other CSC where SPay works.

AGAIN WARNING!
Be VERY very carefully with these Combination Firmware...
Today 1 user told me via PM...
He is successfully on Combination Firmware... BUT Wifi option is not available for use with WiFi Odin...
We have no solution yet, how to connect without damage device... to USB cable...
OWN RISK!!!
Risk to "softbrick" and/or you are NOT able to flash other Firmware again...
Only as hint.
Best Regards

Please, need info/confirmation.
If Combination Firmware writes older sboot Bootloader aka downgrade...
This should be possible to test with SDB and this Command:
Code:
cat /proc/cmdline
Thanx in advance.
Best Regards

Any newer version ?

This means """Combination""" Firmware...
If you not know what it is.
NOT use it.
Own risk.
This is NOT normal leaked Firmware...
Samsung NOT share Gear S3 Firmware...
Only official Firmware updates are over the air... called FOTA...
Odin nor Net Odin nor WiFi Odin...
These are all leaked stuff...
Odin is Service Tool for authorized Service Partner... NOT for public...
Firmware is also leaked... from Service Partner...
Combination Firmware are special Service Tools... NOT for public... NOT for End User.
Again, if you not know what you are doing...
Better not try...
Risk to "soft brick" your Gear Wearable...

You can use Google...
Maybe then more clear what Combination Firmware can do...

I bought early Korean import of gear S3, but I live in US. I did not know SPay would be shut off. Very annoying. Now looking to flash stock ROM that matches my region. I understand this is a common issue.
I have been away from flashing for a long time, but if I understand the information in this forum correctly, flashing a new ROM will automatically cause the S3 to update its region internally. However, downgrading your Tizen version will softbrick the device.
I have SM-R770. Tizen Version 2.3.2.4. Software version BQ--->D<---2. I should NOT attempt to flash this BQ--->C---<2 ROM for risk of softbrick, is this correct?
Please confirm. Thank you!

This is IMHO not correct.
Country/Region aka CSC change require special procedure... with Combination Firmware.
This happens not automatically...
Product Code is stored on device in """"protected""" area...
It is not impossible to change Product Code... but is not easy with Flashing via Odin...
Software version BQ--->D<---2. I should NOT attempt to flash this BQ--->C---<2 ROM for risk of softbrick, is this correct?
Click to expand...
Click to collapse
Yes, in main correct...
This Security crap is Bootloader related... sboot.bin...
As Info...
These Firmware packages are 1:1 from Samsung Server...
In theory, if you remove sboot.bin and cm.bin... it could be more safe to flash older Firmware...
THEORY, not confirmed yet for Gear S3
I am doing this only with my Gear S2... SM-R732...
...risk of softbrick...
Click to expand...
Click to collapse
IMHO it is closer to Hardbrick...
As Security disable wireless Download Mode...
To solder 4 wires to PCB... to have USB cable...
This is IMHO Hardware stuff...

Special Thanks to

@Quick Silver
@aslam4580
For these combination work.
Hit likes and inform comment section if it works For you.

This is the method I used to change the CSC code on my SM-R760 to an Australian code with a view to setting up Samsung Pay. It took a little hunting around the forums to find all of the information, plus I ran into a few things while I was doing it that didn't seemed to be mentioned elsewhere so I thought I would summarise it all below for us noobs.
All credit to the experts, in particular @adfree
WHAT YOU WILL NEED:
------------------------
NetOdin3
https://forum.xda-developers.com/gear-s3/development/rom-samsung-gear-s3-sm-r760-t3588062
Combination Firmware
https://forum.xda-developers.com/showpost.php?p=74600026&postcount=26
Your current stock firmware (in my instance, R760XXU2BQC5)
https://forum.xda-developers.com/gear-s3/development/rom-samsung-gear-s3-sm-r760-t3588062
Your CSC code
https://forum.xda-developers.com/showthread.php?t=787163
A PC with a WiFi connection
INSTRUCTIONS:
----------------
1. Check reactivation lock is off
- On your phone, go to Samsung Gear App
- Go to Setttings Tab, choose "Find my Gear"
- Make sure Reactivation Lock is off
2. Connect your watch to your PC
- Hold down the home/power button until you see the "rebooting" screen
- Release the home/power button then quickly press it three times to bring up the boot menu
- Quick press the home/power button to cycle through the menu to "Download (wireless)"
- Long press the home/button to confirm the menu selection
- The phone will then go into WPS mode
- Double press the home/power button to change to AP mode
- On your PC, enable WiFi and connect to the access point on you watch.
NOTE: Until you successfully connect to NetOdin, your watch may display red text stating "Connection Timeout" - this is OK
- Open up NetOdin. You should now be connected to your watch (you should see the IP in the NetOdin window and "Connected to xx.xx.xx.xx" on your watch face.
NOTE: I had to disable Windows Defender public firewall temporarily for NetOdin to work properly
3. Flash combination firmware
- Load the unzipped .tar.md5 file into the "AP" box of NetOdin, wait for it to finish checking then click "Start". This should take about 10 minutes to complete after clicking "Start".
NOTE: I had left "Automatic reboot" ticked in Odin, so once it completed the watch restarted. No issue, except had to go through step 2 to reconnect the watch to the PC before proceeding to the next step
4. Flash CSC file from stock firmware
- Load the unzipped CSC_xxx.tar.md5 file into the "CSC" box of NetOdin, wait for it to finish checking then click "Start". This should take about 1-2 minutes to complete after clicking "Start".
5. Factory reset
- In your Gear, go to Settings > Gear Info > Reset Gear > Confirm
NOTE: I got a warning at this stage that Reactivation Lock was on. Don't know why I got this message as I had definitely turned it off in step 1. I ignored it (no guts, no glory!) and was fine. Your mileage may vary
6. Set CSC code
- In the Gear, go to the Tizen Keystring app
NOTE: screenshots of what your interface will look like https://forum.xda-developers.com/showpost.php?p=74591475&postcount=13)
- Type in the following code exactly: *#272*719434266344#
- You will be taken to a list of CSC codes that you can scroll through. Find the code you want to change to and select it. I used "XSA".
7. Reflash complete current stock ROM
- Load the unzipped CSC_xxx.tar.md5 file into the "CSC" box of NetOdin, wait for it to finish checking.
- Load the unzipped AP_xxx.tar.md5 file into the "AP" box of NetOdin, wait for it to finish checking.
- Load the unzipped BL_xxx.tar.md5 file into the "BL" box of NetOdin, wait for it to finish checking.
- Click "Start". This should take about 15 minutes to complete after clicking "OK".
You are done!
After this, my Gear picked up the OTA update to Tizen 3.0.0.1
So after all of this effort, NAB doesn't currently support Samsung Pay, so I can't 100% confirm this will work, but everything I've read says it should.

Do you have phone audio working through Bluetooth headset?. Or only media audio... Pls let me know. Thanks

I have already upgraded my S3 to Tizen 3. Am I still able to unlock Samsung pay using these instructions or am I too late?

At the moment we can downgrade to BQC2 from CQK3...
Please check first if you have CQK6...
Best Regards

Can someone please provide a step by step guide to downgrade from Tizen 3?
Thanks!

This guide works great, thank you so much!
Successfully downgraded from Tizen 3.0 simply following the instructions and using ROMs from 1st post, changed region and after that SPay started working!

Nothing to worry follow the steps.if you want to put csc as XAR.then also it will enable spay.

Has anyone from Canada done this yet? Is there a benefit to switch the CSC back to the original (i.e. Original = Canada, flash US, then restore back to Canada) after installing Samsung Pay?

I have updated my S3 to R760XXU2CQL1. Where do I find this firmware if I need the current one in one of the steps?

R760XXU2CQL1 as Odin package?
At the moment only on paid sites... for money...
But in theory... depend on your CSC... you can reach CQL1 via FOTA update...
We have for SM-R760:
Code:
BQC5
BQH1
CQK3
As Full Firmware for use with netOdin...
If somebody share... CQL1 also possible.
Best Regards

@adfree, this is first post on S3. I can see your huge contribution in S3 development.
I am in India. I have bought S3 from UAE on 2nd Jan 2018 and was already updated Tizen 3. Yest got update R760XXU2CQL1..(battery improvement update)
Samsung pay was not working by holding back button since start. (really surprising, how samsung understand that we are in India and then disabling button)
So my question... Can I follow all above steps to get samsung pay..

Well, it says so under "Software version" in Settings. Guess it's the latest battery quick-update.
I bought a german S3, which Samsung Pay obviously won't work for me in Sweden. Which I wanna fix with NetOdin. But as I need the current firmware, it seems I hit a wall....
So I can't downgrade to R760XXU2BQC5?

@swasha123
Yes, you can use steps from CQL1...
Own risk!
@welph
Same for you.
You can downgrade from CQL1... to change CSC...
But you can not direct jump after Combination Firmware to CQL1...
As CQL1 not yet available for free...
But you can flash for instance BQC5, BQH1 or CQK3... then update over the air... aka FOTA.
The only question is... which CSC you want to use...
XAR for US ?
Or you want try something else...
Best Regards
Edit 1.
For German DBT I am sure this Firmware history for FOTA:
Code:
BQC5-->CQK3-->CQL1
For XAR.... US CSC:
Code:
BQC5-->BQH1-->CQK3-->CQL1
But for Sweden... no idea which CSC...

@welph
Same for you.

Yes, I guess XAR would be the one I choose. I know about NEE for us in the nordic countries.
But if I downgrade to some version which is closest to CQL1 with Tizen3, which would that be?
And will the Gear S3 fetch new fw-versions like it does for me now?

But if I downgrade to some version which is closest to CQL1 with Tizen3,
Click to expand...

You could update with netOdin to CQK3... this is the old Tizen 3 Firmware...
Then FOTA update package is only 20 MB...

@adfree thanks for all the help!

@adfree, as I want to install Samsung Pay.. I am already on CQL1
But then combination firmware is BQC1..
Rest I know.. It will work.
Will BQC1 make any trouble to CQL1 downgrade?

Will BQC2 make any trouble to CQL1 downgrade?

You can rollback any firmware into R760
Install through net odin this one: https://forum.xda-developers.com/gear-s3/development/rom-samsung-gear-s3-sm-r760-t3588082
After that you can install any firmware.
Downgrade from Tizen 3 is possible too.

@r4yv3n
I have tried from Combination Firmware 2BQC2 to 1APK7 without success.
You are sure you can back from Software Revision 02 to 01?
@chiyeung524
Problem solved?
Device is alive again?
Best Regards

For few CSC/Sales Code BQH1 is not in FOTA database... but BQC5...
But you could direct flash CQK3...
https://forum.xda-developers.com/gear-s3/how-to/rom-r760xxu2cqk2-samsung-gear-s3-sm-r760-t3712576
Usefull would be... you know your CSC/Sales Code... as few CSC received:
CQK6
Otherwise your next update via FOTA takes "longer"...

Question regarding combination file's

Hello
I see
http://fota-cloud-dn.ospserver.net/firmware/DBT/SM-R760/version.test.xml this url it's from combination firmware right? for testing porpouses version
If i install this combination with ODIN: COMBINATION-FT30_R760XXU2CRB1.zip i get OTA updates from link above? (or i get any OTA update?)
edit: and samsung pay work with this fw?
thanks in advance

IMHO Combination Firmware is something else... as Stock Firmware... and Engineer Firmware you see on this FOTA Test Server...
IMHO Live Demo Units have access to Test Server...
Like SM-R760X and SM-R770X...
I have never seen/found Combination Firmware where FOTA updates work... it is simple not inside...
Best Regards

Hello @adfree I've been reading your post in kernel and several more posts about Tizen and S3 so it is an honor for me to answer me (thanks to some messages from you I could discover why my modified rootfs.img did not work and ended up in bootloop and desist from continuing hahahahaha)
Then according to what you say, I would have to do with the firmware of a device: SM-R760X which with a NetOdin that did not check the exact model could be flashed (since it is the same device in reality)
In the hypothetical case that I do this SPay firmware would still work?
Many thanks
EDIT: a rom with: ENG Boot it's correct?
(sorry but i missed a lot of time from Tizen and Samsung.... i'm user and dev of xiaomi devices)

Combination Firmware is Service/Factory stuff...
Samsung Pay is not preinstalled... also other usefull stuff for normal user like me is absent/missing in Combination Firmware...
Be carefully with SM-R760X/SM-R770X LDU stuff...
You can write Private Message to me...
Maybe we can find... how I can "help" you.
Best Regards
