Jah's making me crazy
Hi all - i am defo interested in getting csc changed and learning about how the csc stuff works in the watch - i am a total noob on teh watch front

I do have experience with Cscfeatures.xmls and using sed to inject the code into xmls on my Fold 3 (my Magisk rom has a mechanism to do this)


I am a bit worried about my watch however - my partner has had an update on her Galaxy watch 4 40mm on o2 UK to BUI4

I have a classic on the same network (42mm) and i am stuck on BUH9

My fold 3 is on sky and i have not actually activated the O2 sim that came with the watch - im just using it as a BT version for now as it seems ample for my needs

@adfree Where you able to capture any of the fota delta? Just curious to find its contents.

I was hoping for frija to pull fw for watch 4 since it's update mechanism is similar to galaxy phones but ended in disappointmen
SamFirmware, Frija does not work with Samsung watches as per my conculsion. i.e you cannot download binary form files from Samsung FOTA servers anymore. They will give Error 200 , could be the files are now kept on a different server.

@adfree were yoy able to capture the firmware update link for the firmware posted above.

there is a tutorial on how to capture links.

It's inconclusive. OTA updates always uses different host name but in case of pulling out full firmwares, the request seem to be different and the server does not honor it. It never responds with resource not found but a bad request meaning the request isnt what the server expected.

Also, 200 is not an error code. It means the request is successful and a response is sent.

Hello Everyone.

I visited Ireland for a ms and got a demo watch classic 4.

Can we somehow flash the normal firmware for the watch to work perfectly.

(I know I ****ed up, was going to buy active 2 from cex store but god no why I bought it from a teenager.
If there is no work around I'm planning to dump it, thought let's check if there is something can be done)

Delta FOTA files...

If I look at Samsung S9 stories...
Then something like this could work?

4. Select "apply update via sd". Navigate to the file, and select it. If you don't have an sd, select "apply update via adb".
Here's an article on how to adb sideload
https://www.theandroidsoul.com/how-to-install-ota-updates-manually-using-recovery-and-adb-sideload/



I still have no GW4 nor I am drunken enough to buy such device without available Firmware... ROOT etc...

According to this Photo:

GW4 have such menu to apply FOTA Delta manually...
NOT tested risky... danger explode ... own risk.


Maybe somebody is drunken enough to test...

To provide the incremental Delta FOTA file is not impossible...

Easier for me is:
Code:
SM-R860
SM-R870
SM-R880
SM-R890


Maybe "soon" new Firmware available for KOO... aka South Korea...

Code:
R860XXU1DUJA/R860OXM1DUJA

Maybe if this Version or similar will be released... i could upload the Delta FOTA from BUI5

Seems most CSC hang on this Version...
Code:
R860XXU1BUI5/R860OXM1BUI5

Delta size seems around 100 MB... so maybe improved Watch Faces... :devilish:

    A.1
    Update over the Air is possible via Phone AND via Watch in Standalone Mode...

    A.2
    If I remember correct... not activated eSIM blocks something in FOTA process...
    Only Samsung knows why they are doing this s hit...

    B
    Go to Service Center...


    @tids2k

    ?

    He has OXA Region...

    Why he should try OLB?

    Why Odin/netOdin if only FOTA Delta aka incremental...

    ?

    I am not confused... I am shocked for these hints...

    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.
