i'm on R875F with EVA8 too, but when I use *#272... to change CSC, nothing happened. I double checked the IMEI I typed but still, nothing happened

Hello, I am willing to change my watch's CSC from INS to MEA to enable gpay/spay, would it be fine? If anyone has tried it and its working please let me know.

I've read the whole thread and have seen a video around 3 months ago on youtube regarding this and it was working fine for them.
I am experienced with such things from a long time.
As far as I've seen the thread the *xxx*IMEI method works fine just once and we are not able to do that again via anything, combination files or anything.. or is there a way?

I just want to know if there are any major issues?

1. Would LTE work?
2. Would OTA updates work?
3. Are there better csc than MEA/SER/XSG or which one is the best among these?

Thanks

I have a little question .... I unzipped the file but there are many ISOs. usually there were 3 files that I put in ODIN and it was very simple. Is it another procedure? thank you very much

@Sorinbalcon

Be sure you only unpack TAR file... NOT all files from TAR...

I am sure I can do this successfully with 7Zip Tool on Windows...

Result for SM-R870 is:
smR870_EVA8_OXM_v1.tar


For SM-R860 I made:
smR860_EVB4_OXM_v1.tar

1 TAR File for netOdin

Simple select 1 TAR file in AP...


Summary:
unpack 1 TAR file from 7zip package...

NO rename No add no nothing to change... simple 1 TAR file to select in netOdin


Best Regards

I have still no USB connection...

To use RDX Tool...

B
Still no idea how to see Upload wireless

My SM-A202F offer way to dump to SD... seems only external SD card...

GW4 not offer SD feature as it seems...

Only as info...

how did you manage to get in upload modus on the sw4?

Upload Mode on my SM-R860 GW4...

*#9900#

A
I set Debug Mode High

B
I enable Upload Mode

C
WLAN Upload ON but no visible effect...

No idea when where I can see changes...


Then I can hold both Keys for few Secondes to force "Hard Reset"...

Then I can see Upload Mode for RDX Tool... USB...

Thanks that worked.. If only the guy can give us some information about the service dock/pogo.
Download modus over wifi seems to work because its creaping an ap.. but upload modus doesnt seems to do the same. If i can find a cheap broken watch 4 i could try out your pin idea

Any way to use OWO CSC codes into an European GW4?

 

[adfree]

@Omegared37

A

IMHO better to write Model Name...

Example:
SM-R860

To prevent mistakes...

B

Also helpfull to give more or better all details about your plan...

If I see "European GW4" and "OWO" then my tiny brain translate into:

SM-R875F is OXA Region...

So OWO is impossible...

DBT is German CSC and inside OXA.... but not in OWO...


C

My tiny tests with Phone SM-A202F...

It is rooted and I can do few things CSC change...
But it is complex and not easy and require other APKs...

My ideas from this thread not work... so I was WRONG.

F. Security is stronger...

D

I saw yesterday that Z3X supports CSC change... Video showed something about ADB...

Not sure if on normal Stock Firmware possible...

Not tested...

But IMHO few Commands left or exists...

Only as info...


I will write summary what I have tested on my SM-A202F Android 11... CSC related...

If I have time...

I see only short Preconfig Window white/empty... but close automatic... so blocked IMHO by some more Security crap...

B

Normal Code input not work for me... so used cool APK since Years very usefull.

But only 27262826 opens correct Preconfig Screen...

Other Codes leads to Errors like on Screeenshots visible...

Remember my SM-A202F is rooted with Magisk...

C

Short checked with Keystring_factory_FB.apk... taken from any Combination Firmware blabla...

No luck with *#27262826#

But for instance with *#197328640# not working in normal "Keypad"...

Only as info...

It is ADVANCED secured against easy Hack...

Only advanced way(s) could work on GW4...

Depend on Firmware Version because we are EVER behind Samsung...

1 old method on LTE devices with IMEI seems obsolete...

Is it possible to change the region of the Galaxy Watch 4?

Maybe if I have time i will reset SM-R860 and start in Standalone Mode...
Without Accounts like Google and Samsung etc...


Btw. Account...

No need to register... Activity Launcher start ...

Edit 1.
Hmmm... missing Knox Setting maybe because...
Played short with my SM-G920F ... enabled Knox but skipped KLMN EULA... then Knox setting gone...
Will charge my SM-R860... Factory Reset... and start from scratch in Standalone Mode...
Without Pairing s h .t

 

[dalepl]

Unless the watch is different, rooting a Samsung device will break knox. Will not be able to recover knox.

You are absolutely right.I should have explained better.
My GW4 is the SM-R875F model. I bought it from Amazon Spain, but the CSC is OXA or something like that. So I ondered...is there any chance to integrate CSC codes from other firmware in order to enable LTE plans to be discovered(in COlombia)?

Hmmm...

I can not activate Knox feature on my SM-R860...

If you enter this Code... you see "full" infos about Firmware Version...

*#1234#

Maybe you can tell us these infos...

B

OXA is Region Code...

In case of SM-R875F OXA contains multiple CSC setting fileS... aka CSC aka Customer Sales Code

Example... DBT for Germany... we can "compute complicated high ciphered" Link:

According to Tizen device... COM could CSC.. and OWO Region Code seems...

But no LTE GW4 for COM found...

 

[Omegared37]

That is the point. There is no CSC code for GW4 yet...and probably will never be. My theory is that using the CSC borrowed from either the SM-R825F or R845, COM versions, it would be possible to acivate LTE services in Colombia. Or perhaps the Chilean version of the GW4(which contains the Multi-CSC OWO firmware) could have it hidden into its files. Have had zero luck trying to download with Bifrost(error 400)
