I am still confused...

SM-R910F or you mean BT only Version SM-R910...

R910FAU1AVH2​

Is Combination Firmware... Google spit out where to buy...

Best Regards

Love the theatrics. No, I saw this already and been using that since they were called Halabtech.

Any chance of a normal firmware ?

Combination has no use, because there is no stock firmware to revert back to normal usage.

Yes, It's the BT version of Watch 5.

Thanks a lot in advance if you can manage to get a normal firmware.

Edit 1.

Code:
freshbl:/sdcard # mount -vo remount,rw /
try '/dev/block/dm-0' type 'ext4' on '/'
freshbl:/sdcard # cp Keystring_factory_FB.zip /system/priv-app
freshbl:/sdcard # cd /system/priv-app

To check if problems...

For me it is easier if you ask concrete Question for your device... exact for your device.

Then I can try to help... Because I have no Crystal Ball and only limited time and energy...

Otherwise I waste my time to write in my bad English...

Maybe you realized, that CSC change is not more easy 1 Click in Android 11 Samsung devices...

Users or Owner from INU (India) devices can simple enter Code...
All others NOT...
Look here:


Firmware Flashing with netOdin nor Odin change CSC by easy 1 click...
More NO...

Okay so, Model is Galaxy Watch 4 Classic LTE (SM-R895F) INU version, I've seen the code thing and my point is just to know if LTE does not work for me lets say after changing my CSC to XSG(United Arab Emirates). If I could revert back to INU by flashing firmware/changing firmware files/rooting, whatever is possible.
If you have this information for Galaxy Watch 4/5 and let's say upcoming wear os watches from Samsung, maybe if you make a guide on how to tweak things, it'd take the development further and genuinely interested people with prior knowledge would also be able to utilise and harness.

Best Regards

A

Sorry never used any kind of eSIM device...

Also never hold LTE Samsung Watch in my own fat hands...


B

SM-R895F

I have NO LTE Firmware for netOdin/Odin use...


C

SM-R895F Firmware not leaked from Samsung Server...


D

"""Our""" Firmware ""Dealer"" has no access to SM-R895F Firmware...

E

Only to US Firmware...
BUT SM-R895U can create new/more/other problems for you...


F

I see posts where users after CSC change have no FOTA updates anymore...

1 reason they are not really understand how this work...

Example... why choosing text string in Developer/Engineer Menu... if this is not supported by FOTA Server?

MEA for instance...

EUX

You see nothing... correct. Because this is not really valid CSC...

XSG is valid, but look here:

Now we look for your LTE...

I see NOTHING inside XSG folder... this is exact what you will get...
NOTHING, no FOTA Update, because not supported by Samsung


G

Samsung was able to find and block all (nearly all) unauthorized GSPN access...
This is why no leaks...

Also since Galaxy Watch Tizen crap... they did some funny things with F devices...

So problems to get F is not really new...

But since GW4 absolute Mega Knockout... because no F Firmware leaked nor in """darknet""" you can buy...

Same Situation for GW5...

About Rooting...

SM-R895F

A

I have no Firmware and it is impossible to create boot.img... to patch with Magisk.


B

Rooting at the moment only possible with attached USB cable, like this:

B.1

Rooting kills Knox... means bye bye Warranty stuff and some support of Apps...

BUT...

C

Look again at A.

We have no leaked Stock Firmware...

We have no Custom Kernel...

"""We""" could use SM-R895U Kernel from Combination Firmware for instance...

BUT again.

A is Mega KO

    For CSC change SM-R860... we have maybe something "new"...

    Untested... and maybe "dangerous"...

    In theory we "need" only:
    Code:
    optics.img
    prism.img

    "We" could "force" SM-R860 to CSC XAA IMHO...

    I have NO idea if in K01 CSC any of these CSC change Codes work...

    But I know it is possible to "erase" active CSC by prism.img and optics.img...
    Tested with fac files from Combination Firmware on my SM-R870...

    We have now 3 AUGJ

    K01
    Code:
    ALL_K01_R860XXU1AUGJ_R860K011AUGJ_CL22197329_QB41964795_REV00_user_low_ship_MULTI_CERT.tar.md5

    OXT Region... maybe more then 1 CSC... need to be checked...
    Code:
    ALL_OXT_R860TBU1AUGL_R860OXT1AUGL_CL22197329_QB42028072_REV00_user_low_ship_MULTI_CERT.tar.md5

    And OXM package... with 3 TAR Files...


    Only as info...

    I am NOT willing to test self for now...
    I killed my SM-R870... so need new Victim Test Device for stupid Adventure.

    I have NO plan to destroy my SM-R860.

    Best Regards
    Yes, R860 (and I think some other models) have 3 different CSC, for firmware: OMK, OXM, and OXT (This one is the special Thom Browne edition I think, like R860TBU1AUGL)

    Memo to me...

    XSAfreshul:/efs/imei # cat omcnw_code.dat

    Will try to simplify for me...

    Code:
    D:\Android\ADBnew>adb push mps_code.dat /sdcard
    mps_code.dat: 1 file pushed, 0 skipped. 0.0 MB/s (3 bytes in 0.008s)
    
    D:\Android\ADBnew>adb shell
    freshul:/ $ su
    freshul:/ # cd /sdcard
    freshul:/sdcard # cp mps_code.dat /efs/imei


    I hope 1 file is enough for CSC change...

    Edit 1.

    After Command chinese Language is visable as I set TGY for Hong Kong...
    But still XSA und Software...
    Then I did FAC Reset... in Standalone Mode I see now TGY is fully set...

    Flashing now AUGF OLB again to undo Root... and be ready for FOTA update...
    1
    Still no idea what K01 exactly is...

    Is this something official in public?

    "We" can see it is Korea...

    Attached extracted files from optics.img and prism.img with imjtool and 7Zip...


    At the moment I can not check self... if K01 is special like INU in case of CSC change...

    Really cool and helpfull:

    Found this Command here:
    https://forum.xda-developers.com/t/how-to-prepare-smartwatch-for-advanced-functions.4511103/
    In Pixel Watch Forum...

    Reason for this...

    I have realized permission in Manifest
    Code:
    <uses-permission android:name="android.permission.ACCESS_SUPERUSER"/>

    Have no effect for Root access...

    Did few tests...
    Added this line not enable in my beloved Termeinal App

    And in known Root Terminals... this not removed accesses to SuperUser...


    I also realized... There are Keyboard Apps... but this not finally fix my problem...
    Seems really buggy...
    Nothing work perfect...
    Still Chaos...

    Maybe this have something to do with Background Foreground... ever in Foreground Option...

    For now I will backup these Keyboard APKs from my SM-R860 for study...

    Best Regards

    Edit 1.

    Btw... what is this?

    No idea when Full firmwares for study leak...

    Meanwhile to understand maybe more about funny Region... helpfull this Android App to check Firmware:

    It is possible to decrypt from Test Server...

    Then maybe more clear...


    OXM seems also for DBT ZTO and so on...

    A
    In theory linked FOTA Delta should work for AUGE DBT or SER or ZTO...

    Question is only how to update manually...

    B
    Roll out official could be in waves... but could be also more funny like we allready knows...

    We will see the future of GW4 support.
