[Samsung Galaxy Watch 4] Jsigno:
I just bought my watch 4 in China I work here, and it doesn't even connect with the phone (S21 ultra not chinese). I guess the only way is to install the firmware (wireless) but the problem is where to find it and is compatible? Cause the name of my watch is SM-R870NZSACHC and reading all the post nobody mentioned this serial number. :cry::eek::eek:

Thanks everybody

So it seems that normal recovery present on the watch. more headroom for TWRP. Also was able to go to fastboot however no way to connect over WiFi. What also seems as a potential to unlock bootloader. ( fastboot oem unlock ) confirmed via parma inages posted before.

Download mode has an option to unlock bootloader, however will need to have oem unlock option in developer options which is not the case.

How to go to bootloader :

adb reboot bootloader. -> will take you to fastboot mode. however wont connect over wifi, need physical connection to poco pins on watch.

once in fastboot mode. procedure is same like previous watch.

In regards to CSC, decompiling CSC.apk, AndroidMafiest.xml

<intent-filter>
<action android:name="android.provider.Telephony.SECRET_CODE"/>
<data android:host="9920" android:scheme="android_secret_code"/>
</intent-filter>

We know that 9920 will trigger CSC , however tried both via dialer and adb shell

adb shell am start -a android.intent.action.CALL -d tel:%2A%23%2A%23%39%39%32%30%23%2A%23%2A

Did not appear to work, maybe less *#9920*# ?

[Samsung Galaxy Watch 4] Xdenwarrior:
Hi, first post in a while.

All I need to know is how to safely revert my Galaxy Watch 5 Pro to previous AVI4 version from current AVK6. I've done this multiple times on the phone and personally never update my phone, my windows pc or pretty much anything in the past 2 years since Samsung, Microsoft etc pretty much always take away features instead of adding them since they already have everything ahead of Apple and now the only thing left is to add this bit of so-called security by trimming and locking down their software these days.

Anyways, I might have been out of my mind to update to latest wear os version on my Watch 5 Pro thinking it would enable the new temperature sensor drivers but instead it secretly got rid of my custom ringtones on my watch. Now that's no biggie since a few adb commands is all it took to re-enable them. But now I noticed that my favorite bubble cloud wear watch face no longer auto updates live weather or show the accurate phone battery percentage on my watch. And that according to developer is cause Samsung changed how background processes are handled in new AVK6/7 firmware which breaks that. And that which I have been using I can not fix. So simple solution downgrade software and add watch 5 pro as my other device to no update list! After all, if it ain't broken, don't fix it. So yeah sorry for long post, just want to know how to go from current AVK6 to previous October AVI4 cause everything there worked perfectly for me but I couldn't find any concrete info about it so posting here since you all are discussing about sideloading firmwares.

For downgrading it's only dangerous if bootloader of the watch is not the same. Or is there anything else I should be aware about?

I use Samsung Pay on my watch and certainly I don't want to trip Knox. My rooting days are long gone since everything runs fast and have plenty of storage nowadays.

However, I might have ran into another issue - I can't find Canadian AVI4 firmware. Maybe there is an program that could retrieve it?

The firmware will have to be the same thou as Canadian varient of Samsung LTE watches have different modem hardware as far as I know.

Hi.

If I understood correctly it is possible to wirelessly connect the watch with the samfw frp tool program.

Can you explain the process that must be carried out in detail?

I am familiar with the program and the csc change and would like to test if it is possible to do the change on the watch.

I usually write in Spanish so I'm sorry if there is something that is not clear when using the translator.

I have no Phone to test yet... but CSC change seems not done via ADB... but with Samsung Modem Driver...

Best Regards
[Samsung Galaxy Watch 4] ser8210:
Thanks.

I am going to try. Indeed, the program uses adb to read the csc codes that are available and little else. Reboot for example. I don't have the list of adb commands handy right now as I know the csc available on my phones. Indeed it is a matter of the AT+ commands that are sent to change the status and parameters through communication with the modem when it is in test mode. I tried the commands from the yat program console with good results, always with a usb connection and that is why I am interested in being able to test if it is possible to do it without a physical connection. Now I write you the AT commands that are used.

Salu2

Edit.

The commands.

I put phe because it is my region and it was to return after a previous change. By the way, in my case I have the sm-r890 model and it enters test mode without problems by dialing *#0*#

[Samsung Galaxy Watch 4] ser8210:
No, no.....

I feel the confusion. The csc change was done on my phones with the usb cable. I did not perform any modifications or soldering on the watch under warranty and this is the reason why I am trying to do the process wirelessly. I am also not rooted on the phones. I want to do it with this method because root is not required and it doesn't alter the knox. I know that the test mode works well on the watch because it is the first thing I tried when I started testing.

Prepare step...

A

mps_code.dat

Unpack... open with WinHex or other Editor...

Change in DBT or TGY or whatever you dream to have as active CSC...

Important. This Text must be in Firmware package...

B

Basic Commands... I hope connection can be achieved without additional help...

adb connect IPaddress

Then push edited file:

adb push mps_code.dat /sdcard

C

Then this is to activate system user aka system shell aka mighty power like OS...

D

Copy EXE and APKs into same folder where your ADB is...

adb connect IPaddress

E

Look at screenshots...

If this happens, then you can enter Commands as SYSTEM user...

Caution...

Double click could lead to crash of EXE... some other things leads to crash...

In main NOT Reboot Watch to prevent damn Watch is faster and replace APK with new again...

Only reboot Watch if EXE only crashes...

F

If stable adb Window like on screenshot...

cd /sdcard
cp mps_code.dat /efs/imei

active CSC is changed...

You can controll/check by typing:

cd /efs/imei
cat mps_code.dat

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.
