For instance NOT all Bankcards supported etc...

@adfree 1 more question.

I think we don't changed the CSC as fully.

As you can see, there are 1 more CSC file that we need to change, Samsung Pay can't adds my card, so there are a problem.

We need to change "omcnw_code.dat" too. But I can't copy it to /efs/imei because of permissions. If we can reach to temporary root access, we can do it too and it's gonna work properly.

I have installed GWA3 Update on my German (DBT) SM-R860 via FOTA update.zip Delta file...

From GVK7... with help of earlier mentioned System Shell exploit...

Here is the Delta file:
mega.nz

329 MB file on MEGA

mega.nz mega.nz

GVK7 --> GWA3 SM-R860

Step 1 is to push the file to device with ADB.

Code: 
adb push update.zip /sdcard

For Step 2.

Later... I need some tester... to confirm...

But in general Exploit... then Command for FOTA Admin... looks like my Screenshots...

OWN RISK!

Best Regards

The second part is... to bring the FOTA Admin menu

Exploit to bring System shell...

Then Copy and Paste this:
Code: 
am start -n com.wssyncmldm/com.idm.fotaagent.enabler.ui.admin.main.AdminMainActivity

This brings the FOTA Admin menu... scroll down... choose the Local Test...

Select update.zip... press ok

Again.

OWN RISK!

    Oh nice.

    I have "updated" my SM-R875F from GWB1 OLB to US Firmware via USB cable and Odin...
    R875USQU1GWB2/R875UOYM1GWB2/R875USQU1GWB2

    This time my WiFi detected and connected...

    So I can play little bit... with US Firmware...

    With old FVD4 I had no luck to find my WiFi AP...

    For stupid tests this is much better...

    Only Contra for now... no Bootloader Unlock so no Root yet...

    Hi,

    I really need help - during a failed OTA upgrade my SM-R875F is now stuck in download mode.

    I really nead a rom for SM-R875F UK/EU that can be updated normally (not just stuck on the rom version).

    I have only been able to find the Australia rom (July 2021 version for F but I cannot update the rom) and the USA (R875USQU1GWB2) rom (esim does not work in UK).

    Or if anyone can assist with getting the Australia rom (smR875F_AUGF_OLB) on this site to update that would help!

    Or getting the USA rom to use the UK/EU esim - maybe CSC and modem.bin needs?

    All help please!

    No idea when Full firmwares for study leak...

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

    CheckFirm - Apps on Google Play

    Search Galaxy device firmware easily.
    play.google.com play.google.com

    It is possible to decrypt from Test Server...

    Then maybe more clear...
