Friendly user told me about this Tool...

I have installed this Version:
Code: 
7z22.01-zstd-x32.exe

Now I can easier decompress *.lz4 Firmware Files...

NOT fully tested... OWN Risk!


@shaker74


Please Model Name example:
SM-R875F ?

Firmware Version on your Device?

Code: 
*#1234#


I have for instance not tested to downgrade from GWDA...

I only read user with luck was able to downgrade on SM-R895F... with netOdin

To our chinese users...

Or if somebody is interested...

Frija... Bitfrost... Fuddy and maybe more can download LATEST chinese Firmware for BT only Models...

Code:

I have a GW4 Classic watch (SM-R895FZKAINU) with software version R895FXXU1GWDA. I would like to have Samsung Pay on it for which CSC of MEA is needed. Is it possible to downgrade the firmware to an older version and change the CSC?

    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.

    Need few attempts...

    But good I can edit system.img without crash... so no Hash check or something in this Direction...

    Edit 1.

    Step 1 done in funny riddle... puzzle...

    Need more time to correct the other props...

    Goal is to enter exact Playstore for GW4... and/or Samsung Apps...

    In Emulator on PC...
