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...

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:

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...

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.

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...

SM-Z300H... because it was designed for...

Gear S2 Classic BALR
hi...i am from the Netherlands and my s2 Classic Balr stuck in the boot loop and i tried a hard recovery but still in tge boot loop. Now i wanna try to flash it through odin latest version 3.12.10....but i dont now where to find the (latest) firmware of this watch?
Could someone help me?

Oh! If I knew how to, I would port Android Wear to the S2 right now! It's my first experience with a smartwatch, and I love the fact this one is small enough for my wrist, and it looks gorgeous compared to others available in my country. I know, if I wanted Android Wear I should have bought a Moto 360 maybe (though I dislike the lower dead area on the lower end of the screen) but I got a really good deal for this S2, I couldn't let it pass. Anyway, I hope someone is able to port Android Wear, I'm willing to test when the time comes.

Hi. Can anyone help me connecting my SM-R720 gear s2 via usb to pc to enable flasing using odin?
I'm unable to access download "wireless" mode so I'm hoping there is some sort of diagram of the jig somewhere enabling usage of the 5 spots under the cover to connect it via USB?

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.

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...

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,

You could update with netOdin to CQK3... this is the old Tizen 3 Firmware...
Then FOTA update package is only 20 MB...
CQK3 for SM-R760 is here:

@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?
Click to expand...

You can downgrade from 2CQL1 to 2BQC2

Because few users have no luck

Watch is stuck on the logo and won't boot up

My watch is completely stock and I have never done anything to it but I tried to turn it on today and it is stuck on the logo and doesn't go any further. I tried using recovery but that just gets stuck on the logo as well. I am able to get into (wifi) download mode so I am reaching out to you guys for help maybe I can flash something via odin net to get things working again I appreciate any help.
Here is some info I got from Odin mode:
Product name: SM-R770
Current Binary: Samsung official
System status: Official
Reactivation: OFF
Secure download: Enabled
Warranty void: 0 (0x0000)
AP SWERV: B:2 K:0 S:0

I have only CQK3 as """latest""" Tizen 3 Firmware for SM-R770...
https://www.file-upload.net/download-12979722/R770XXU2CQK3_OXA2CQK3.zip.html
netOdin and instruction you could find here... if you want:

Thank you! I will check it out when I get home. Am I able to receive OTA updates with this firmware?

I have no Crystal Ball.
As "we" not know what happens to your device and why it stuck...
CQK3 is IMHO the only leaked Tizen 3 Firmware... for SM-R770.
If you successfully flash CQK3... I am sure we find solution to fix FOTA...
Alternate solution is buy Firmware.
Here for instance:
http://dl.pars-hamrah.com//index.php?file=/Samsung Flash Files/R Series/R770 Orginal Firmware
CQL1 for SM-R770...
But also SM-R770 is CRC3 the latest FOTA update...
Your decission.
Own risk!

That is weird, mine did the same thing yesterday. My phone kept saying "Gear S3 Plugin keeps closing" so I cleared data and cache. It disconnected the gear and the gear said rebooting. Then it got stuck on the boot screen. Mine is the SM-R760 instead of the SM-R770. All the other information is the same as the OP. Can someone let me know what version I should install on my watch, if it is different than the R770. It had just installed an over the air update the same day, so it is on whatever the most recent version is. As long as it is able to downgrade I don't mind going back to tizen 2.3 if that is what it takes to fix it, I just don't want to mess it up if it isn't able to downgrade. Thanks in advance.

@adfree , you are amazing!!!!!!!!!!!!!!!!! I just tried what you said and so far everything is looking great! I got the FOTA and I'm extremely happy Thank you thank you thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

@adfree Thank you for your help. I had seen that forum page with the CQL1, but I wasn't sure if I could downgrade from CRC3 to CQL1. I have a US version Gear S3, but the firmware says Europe. Can I still use this file, and if so do I need to do anything special? I have watched the youtube videos and it never mentions the .pit file, should I use the .pit file when imaging? Thanks again!

All CSC/Sales Code are inside 1 package...
So this Firmware is also for US Sales Code XAR... SM-R760 Frontier.
!!!
Please do only this what you see in Videos...
Select AP in AP, BL in BL, CSC in CSC...
You have only to """sort""" select 3 files...
Three files
I'll repeat:
3
NOT change any Settings in netOdin...
NOt add PIT
Btw...
PIT is allready inside CSC...
I'll repeat... summary:
3 files
Best Regards

@adfree I don't blame you for making it extremely clear, the last thing I want to do is mess up my watch. I appreciate it. I flashed it this morning and it failed for some reason the first time. I was worried it messed something up, but I put in a more reliable wireless adapter and tried again, and passed!!! Thank you so much for your help. My watch is still under warranty, but I am overseas so it would have taken months to send in for repair probably. It updated to CRC3 almost immediately and it is completely functional again. Thank you so much for your help!
