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.

No idea why...

But seems I have read AND write access to /system... GVH2

Code:
freshbl:/system/priv-app # rm -r GalaxyStore

Need some time for stupid tests...

Only as info...

Best Regards

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
freshbl:/system/priv-app # ziptool unzip Keystring_factory_FB.zip

I will try first to remove few more Apps...
Before modify or add...

Removed:
Galaxy Store ... for later play...
FOTA Agent ... to prevent Update... I have Root...


Added:
Factory IME from Combination Firmware




WISHlist:

A

More then 1 Minute screen time...

At the moment no idea where...


B

Modified System APKs...

First attempt few days ago with Magisk Module fail...

So I have more to search in XDA or Google... other Android 11 devices...


C

More APKs to add...

Will test to add Magisk... and my other must install Apps...

Few of them splitted...
No idea yet... maybe convert into 1 APK or I can find working Single APKs...


D

I hate this s h ttt...

I disable BT in hope of better Wifi stable connection... after Reboot BT is enabled by default...
This s u x xxxxX

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

    I want to make a small contribution to the thread in question, I have a gw4 ldu which did not allow any device configuration. I downloaded the SM-R890 EVA8 file and unzipped it with 7zip and then retransformed in tar format again with 7zip. I then connected the gw4 with netodin and uploaded the file to the device. Finished the job everything works wonders, it also received the latest update released by samsung. Tanks to Adfree for his hard job

    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.
