Hello,

Let me firstly apologize for my question but for the life of me I cannot seem to understand the purpose of this thread. Doesn’t the gear s2 pair with the iPhone out of the box ? Using the gear s manager app., or not, or is this for locked devices only?

Is EQC1 r732x compatible?
[Samsung Gear S2] adfree:
Really good question. :o

EPK5 seems to disable Download wireless Mode on Live Demo Unit...

I have no idea if EQC1 is more Live Demo Unit "friendly" or more sideffects...

In theory chance EQC1 not work with SM-R732X + problem to flash other Firmware, as WiFi disabled.

THEORY! Not tested... own risk!

Best Regards
[Samsung Gear S2] gingerdude:
So even if it isn't very r732X friendly the flash should still complete and work....its just there's a good chance wireless download mode may then be missing?
[Samsung Gear S2] pavlos46:
Adfree since you do have a USB setup could you please test the EPK5 version on your retail watch and see if the wifi download mode is still works.

I am thinking that maybe the problem was the firmware and the demo watches.

Also on my stuck demo 720x unit wifi connection on normal usage works so (with the help) of someone that knows I would like to connect through sdk and active fota.

[MENTION=3119752]pavlos46[/MENTION]

EPK5 and EQC1 tested on my Retail SM-R732...

Download wireless Mode is "stable" visible... no boot cycle...

But I have not tested to flash via WiFi...

Their are Security differences between USB cable Flashing and Wireless/WiFi Odin...

USB cable is working via Bootloader only... aka sboot.bin... no Kernel boot required...

Download wireless is Kernel start + additional files + settings...

So also additional Security checks...

Unpack ramdisk-recovery.img with 7Zip...

Check for instance:

\usr\lib\initrd-recovery\[B]wireless-download[/B]\wireless-download-init

I have no idea yet... where the Securtiy check is located, to prevent fully start of wireless-download-init

But again... this is Samsung policy/rule/security crap... to prevent too much not authorized experiments...

Like update of devices which are NOT for Sale...

And Live Demo Units are not for end users... normally...

No Panic.

I have also Prototypes and Live Demo Units... ;)

But not from Wearables... :o

And I have NO Crystal Ball...

But many Gear S3 users ended with disabled wireless Download Mode...

And they played with Retail devices...

Also Bootcycle possible...

So this is not phenomenon with Gear S2 Live Demo Units only...

Need Firmware Gear S2

Friends !!!

I made an error updating by net ODIN my GEAR S2 for a European firmware and lost the Samsung Pay app. :(

I already tried to find the firmware on several sites and can not find it!

The original firmware of my watch is this SM-r7200zkaxar (Version US) SM-R720

I went to this site https://boycracked.com/portfolio/download-samsung-usa-stock-rom-firmware/

And on that site it shows all the variants but the links are broken.

Would anyone know where I can find this firmware SM-r7200zkaxar? I even donate by paypal.

P.S. I have already looked for the site Sanmobile and others and even by Sanfirm and I can not find the firmware!
[Samsung Gear S2] adfree:
Can you give more details...

Which Firmware you have tried... and which Firmware is now on your device?

There is NO US exclusive Firmware... for SM-R720 nor SM-R732...

Only 2 multi region Firmware OXX and OXA which contains several CSC/ Sales Code...

XAR is in OXA packages... maybe you flashed older OXX -Firmware and Sales Code is autochanged...

You can simple unpack Firmware with 7zip and extract files from csc.img...

In OXA you will find folder XAR...

Step 1.

Check your Sales Code on device...

Thanks by reply Adfree

Well, I have 2 firmwares version (OXX and OXA both for R720 model) and flashed OXA in my gear more not appears app Samsung Pay . :(

How makes for change CSC code sales for code XAR?

I unzip files with 7zip (CSC file) and not found file specific with XAR csc.Only found CSC.img and Partition.pit.

How extract file CSC.img? I try with 7zip more no read this file.

Dear friend, I extracted the CSC_R720OXA2BOKK_usr.tar.md5 file and now has 2 csc.img and partition.pit files. I'm trying to extract only the csc.img file and it does not extract. :(

Would you have only the code sales CSC XAR R720(without multi CSC OXA) file from the FW BOKK ? It would certainly help other people who want to have the Samsung Pay app on gear s2. :)
[Samsung Gear S2] adfree:
Latest Version of 7Zip is 16.04

http://www.7-zip.org/

With this version I can extract every files from *.img inside Firmware... also csc.img

Maybe check again...

If you successfully extract csc.img, then you will see... XAR is an part of OXA region...

This "magic" SPay require few "valid" presettings..

Minimum on Gear side... valid Sales Code...

This require little bit Background info...

So extracting csc.img is good way to learn and increase knowledge about SPay...

I have NO final 1 click solution for you... as I have NO idea, what "you" have disabled...

I know switch between OXA and OXX Firmware switch also Sales Code... WITHOUT your input...

I spend many hours to find solution for me...

But I not need nor use SPay...

Mechanism is nearly same... for Firmware request from Server... aka FOTA...

Feel free to learn... or... ;)

Extract CSC.img Success!

Ok friend !!! I was able to extract the file "CSC_R720OXA2BOKK_usr.tar.md5" to CSC.IMG and then extract the image file and I was able to see the folders of the codes sales :). In the "preconfig" folder and the "mps" folder contains the countries CSC code. I know certain that Samsung Pay works with the XAR (US) and XSA (Australia) variants. I would delete all folders CSC others country and leave only those two folders(XAR,XSA). Right?

I would like to know how to compress the folders again the files to CSC.IMG format again?

And then how would I compress the "csc.img" and "partition.pit" files with the format "CSC_R720OXA2BOKK_usr.tar.md5" for install again by netOdin (Wirelless)

Commands by keypad

Adfree, I saw another post of yours where you got into the preload csc configuration by keypad for set region in the Gear S2. I am installed FW BOKK and the commands * # 272 *?????# do not accept in my gear s2.

Some say you has to type * # 272 * imei #. But this model with bluetooth has no imei , only serial number! :(

:confused::confused:
[Samsung Gear S2] adfree:
Next step I suggest you.

To install SDB Tool and check active Sales Code/CSC on device.

I have modified Firmware for my SM-R732... ROOTed and few certs added to have more "control"... for playing around.

Checking Sales Code is also possible WITHOUT any kind of Modification...

The main problem it is an "chain"... So not only 1 incredients must be valid... there seems more parts mandatory... this is like an puzzle...

Example here:

https://xdaforums.com/gear-s3/help/samsung-pay-korean-watches-country-t3657714

Here it seems user can "fake" handset side...

So we have 2 sources/devices for "trouble"...

Gear
[B]AND[/B]
Handset

So IMHO it is good idea to check first Gear Wearable... if Sales Code is maybe changed...

I have NO Crystal Ball and I am not the Son of Nostradamus... and I have not the Power of Obi Wan... or any other magic power... to smell Bits and Bytes in your Gear Wearable... :D

Changing Sales Code is easier with ROOTed devices...

It is in theory no problem to create similar modified Firmware (rootfs.img) for BOKK... SM-R720...

But to prevent more irretating things or mistakes or...

We should first check with unmodified Original Firmware....

Maybe I am wrong, maybe your Sales Code is still XAR...

Feel free to PM me...

I can try to assist you to establish WiFi connection with SDB to check Sales Code...

Other way is... if your handset is rooted... we can also do some other things to check active Sales Code...

Easier and better for me... is to help you with SDB... :angel:

You not need to download whole Tizen SDK...

SDB is as standalone package on offical Tizen web sites...

2 MB

Instruction is also somewhere...

I could give you Links for download SDB and Tutorial to connect with SDB...

Best Regards
[Samsung Gear S2] claudioalfatec:
Dear adfree

I have Tizen Studio installed and opened the shell terminal (sdb) and checked the my CSC code that is in the firmware. See the photos attached, it my code set is XEF (variant of France).

I browsed the system folders of the R720 and found the CSC folder. See the photo in the attachment that the CSC configuration file "SW-Configuration.xml" the default CSC code is the XEF on the first line.

One idea is to extract the csc.img file and modify the position of the CSC variants (SW_Configuration.xml), change modify the first line "XEF" to an "XAR" as an example.

After recompile folders extract converting to csc.img , after pack 2 files (csc.img and Partition.pit)this format .usr.tar.md5 and install by netODIN again.

I know that with root I will have the privileges of the system, but I would lose the possibility of installing the Samsung Pay in Gear because of the changed Knox.

Through the commands in the SDB of to install the app with extensions * .wgt and * ipk.

If someone has the Samsung Pay app for the gear platform (extensions .wgt and .tpk), it would have to manually install in gear s2 as in gear 3.
[Samsung Gear S2] adfree:
[MENTION=6968498]claudioalfatec[/MENTION]

Thanx for screenshotS etc. and thanx for trying with SDB.

:cool: :good:

So we can proceed...

Firmware BOKK is older... and IMHO not contain Samsung Pay as installation package TPK nor preinstalled...

com.samsung.samsung-pay-app.tpk

This TPK I saw since EPK5 in SM-R732...

Also in EQC1 Firmware...

You can extract TPK easily from these Firmware... use 7zip with rootfs.img...

Links to these Firmware packages for SM-R732 should be from me somewhere here in this Thread...

At the moment NO problem SM-R732 or SM-R720... TPK should be the same...

If you found...

Then you could install via SDB

sdb install com.samsung.samsung-pay-app.tpk

Launching could be possible via SDB:

sdb shell
launch_app com.samsung.samsung-pay-app

But for me this was NEVER successfully as visible effect...

I have also changed Sales Code to XAR on my SM-R732...

But this app do nothing... :o :confused:

Maybe you have more luck...

Maybe Handset and SIM (MCC,MNC) country location is more important to be from allowed Spay countries...

:confused:

:confused:

Sorry my Focus/Priortiy is on my SM-R732...

So I am not sure if newer Firmware for SM-R720 is leaked FREE available higher as BOKK...

Install S.Pay with success , but no appears in my Gear

I was able to find the file of samsung pay .tpk. I installed with SDB (install / launcher) command but it says it is installed, when I give the "launch" command "Success" appears.

But Gear does not show the S.Pay app. :(

As I told you, before it was running S.Pay, it just crashed because I changed the firmware to a multi-csc OXX. The original firmware was only a CSC (XAR).

In my country (Brazil) Samsung Pay has been available for over 1 year.

I do not know how the firmware switches to the CSC of the country !!!

When I install the firmware it does not change the CSC to the code of my country (Brazil is ZTO). Fimware OXA has the XAR and also the code of my country ZTO.

I already tried to change the language to English on the smartphone.

I even used a VPN connecting on US servers to try to trick the Samsung server.

And even so does not change the CSC. I think I would change the code if I had the first firmware.

There's something that makes CSC change. But I do not know how Samsung identifies the country code and authorizes the change in FW.

A mistery!
