Use accordingly. If you don't know how to flash, kindly use the search option or browse around. Don't know how long I'll keep these up but for the meantime, get them while it's hot.

Flashed the latest and will test to see if System still works or not. Also @adfree can you explain everything you did for your method of halfway CSC change. I believe i maybe have a different method but need you to explain yours first to see if it's the same or different. Thanks.

@wr3cckl3ss1 Did you manage to change the CSC on 895u?
[Samsung Galaxy Watch 4] wr3cckl3ss1:
Still haven't cracked Preconfig menu but made some changes. @adfree yourr method called on taking files in and out, i believe. Look closely at the following. And if this works for you and causes the desire effec5. Then forget about Preconfig and stick to this.

@wr3cckl3ss1​

Nice idea with echo.

Thanx for info.

Maybe I can test this sooon...

I have now flashed SM-R875F OXA Firmware... after long long time no OXA Firmware available...

I am thinking to test R875N Firmware... maybe... I am tooo wimpy for now.

I am scared about the korean sboot Bootloader...

No idea if Bootloader unlock/lock is also in korean sboot.bin... need to check first with WinHex...

In US Bootloader this feature is absent...

But I was also scared to mix F Bootloader with US Firmware... to see if I can short root R875U ...

Maybe 1 day i am drunken enough to check this...

Trying to track down Preconfig menu on this Watch 4. And from what I can see, is a check to /efs and if it doesn't match, it errors giving the response you see in the video, i had posted. "Not Regional Carrier" Will test here shortly. Also will leave a file to look at in regards to the carriers, which is odd to me because I have never seen CSCs like that. Especially CSCs that have a number in it.

[Samsung Galaxy Watch 4] warmbooter:
I ran through all the posts in this thread but I'm still unsure what would be the best solution for my case:

I have a Galaxy Watch 5 Pro Bluetooth (R920) bought in USA (XAA). I live in Brazil, and with the XAA almost everything works here but the blood pressure, since it is not approved by USA's FDA. The Samsung Pay work most of the times. I would like to change the CSC to ZTO (BP is available in Brazil) and afaiu, there would be two ways to do that:

1) Get a GW5 Pro R920 original ZTO firmware and use netodin to put it into the watch - this seems to be the ideal solution, but I could not find such firmware anyware.

2) Use the "shell exploit" and adb solution to change the mps_code.dat to ZTO - I'm not sure if this will work and I'm also not sure if there wouldn't be other files that need to be changed to get a "fully" ZTO system.

Any advice?

But i am doing cp command... and copy to /sdcard

So IMHO steps

adb shell

But if you have working system shell exploit shell is opened for you...

So only...

Something like that...

From /sdcard you can then pull via adb

Samsung SM-R895U Combination File ROM (Flash File)

Download Samsung SM-R895U Combination File (original flash file, rom) without any password for Free. We also provide the combination file for all Samsung devices.

samsungcombinationfile.com

Looks easy to flash it.

My goal is to get working esim on USA version watch in Europe.

What do you think should I try it?

I have a similar issue and goal with the R915U!
[Samsung Galaxy Watch 4] wr3cckl3ss1:
I absolutely wish you both the best in flashing this and if it sticks. Then by all means, let us know here immediately. Maybe Samsung slipped up and left their bootloader in an unlocked position but shows locked? Jokes aside. In order to flash this. You need clearance, lvl 3 token to flash. Since Android 10, Papa Samsung has made it more difficult across the board. But i wish you both the very best.
