I was able to root my SM-A202F with Magisk by Patching 2 Files from Firmware Package:

boot.img
vbmeta.img

First I tried the Original files in lz4 Compression:

boot.img.lz4
vbmeta.img.lz4

Magisk not handle this in this way... after simple put both files into TAR... Magisk patched both files and created TAR with:

boot.img
vbmeta.img

First attempt... :alien:

In Developer Mode OEM unlock selected and then with Odin...

Root work generally... but I have some Touch blocking...

need to investigate if Root related or my halfdead SM-A202F...

I can fix by boot into Recovery and choose Repair Apps...

D

Short tested Combination Firmware... but:

Please get the approval to use factory binaries (PIT)

Maybe I will try later by removing PIT... no idea why repartition needed...

E

a20e:/ # dd if=/dev/block/mmcblk0 bs=512 count=10000000 of=/sdcard/dump.bin

Short checked with WinHex...

Seems not same AVB Format as we see in Firmware Packages...

So hard to use dumped partitions with Odin...

F

During Booting now other Pics with Custom Warnings blabla...

Knox Warranty 1

Will later add Pics what I mean...

Summary.

For Root GW4 we need IMHO no Custom Recovery like TWRP...

But for sure bye bye Knox Warranty Bit... could lead to some "surprices"...

This is what my rooted SM-A202F shows now...

Taken from param.bin

We have similar Pics for GW4...

Will add later...

Best Regards
[Samsung Galaxy Watch 4] adfree:
Pictures taken from SM-R860 EVB4 up_param.bin

So IMHO in theory something similar like on my SM-A202F rooted with Magisk patched boot.img and vbmeta.img could be visible on GW4...

If Bootloader is really unlocked... AND Custom data is written to device...

Seems Unlocked Bootloader not kill Knox if no custom stuff is written through netOdin/Odin... (theory)...

I will spend some time with Log Files and ways to get them...

A

In Recovery Menu... see Photo

View recovery logs

Files seems inside:

/cache/recovery

I will check if I have access to this folder via ADB... in normal boot...

With adb shell and simple copy and paste no way without root...

freshbs:/ $ cd /cache/recovery
/system/bin/sh: cd: /cache/recovery: Permission denied

Will check my files from *#9900#

logdump seems good...

Found 3 files if i search for warranty aka Knox...

examples:

last_dataresizing

warranty bit : 0

trust boot status : 0

----------------------------------------------
last_kernel

warranty reason : (0x0000)

[OTP] WARRANTY read start
[OTP] WARRANTY read value: 0x0

[Samsung Galaxy Watch 4] evil22:
Hello, I am willing to change my watch's CSC from INS to MEA to enable gpay/spay, would it be fine? If anyone has tried it and its working please let me know.

I've read the whole thread and have seen a video around 3 months ago on youtube regarding this and it was working fine for them.

I am experienced with such things from a long time.

As far as I've seen the thread the *xxx*IMEI method works fine just once and we are not able to do that again via anything, combination files or anything.. or is there a way?

I just want to know if there are any major issues?

1. Would LTE work?

2. Would OTA updates work?

3. Are there better csc than MEA/SER/XSG or which one is the best among these?

Thanks

I have a little question .... I unzipped the file but there are many ISOs. usually there were 3 files that I put in ODIN and it was very simple. Is it another procedure? thank you very much
[Samsung Galaxy Watch 4] adfree:
@Sorinbalcon

Be sure you only unpack TAR file... NOT all files from TAR...

I am sure I can do this successfully with 7Zip Tool on Windows...

Result for SM-R870 is:

smR870_EVA8_OXM_v1.tar

For SM-R860 I made:

smR860_EVB4_OXM_v1.tar

1 TAR File for netOdin

Simple select 1 TAR file in AP...

Summary:

unpack 1 TAR file from 7zip package...

NO rename No add no nothing to change... simple 1 TAR file to select in netOdin

Any way to use OWO CSC codes into an European GW4?
[Samsung Galaxy Watch 4] adfree:
@Omegared37

A

IMHO better to write Model Name...

Example:

SM-R860

To prevent mistakes...

B

Also helpfull to give more or better all details about your plan...

If I see "European GW4" and "OWO" then my tiny brain translate into:

SM-R875F is OXA Region...

So OWO is impossible...

DBT is German CSC and inside OXA.... but not in OWO...

C

My tiny tests with Phone SM-A202F...

It is rooted and I can do few things CSC change...

But it is complex and not easy and require other APKs...

My ideas from this thread not work... so I was WRONG.

F. Security is stronger...

D

I saw yesterday that Z3X supports CSC change... Video showed something about ADB...

Not sure if on normal Stock Firmware possible...

Not tested...

But IMHO few Commands left or exists...

Only as info...

Tiny summary of my CSC change adventure in SM-A202F rooted Phone with Android 11...

A

My old idea with Activity Launch via ADB Command:

https://xdaforums.com/t/firmware-an...d-csc-change-and.4323469/page-3#post-85589265

a20e:/ $ am start -n com.samsung.android.cidmanager/com.samsung.android.cidmanager.preconfig.PreconfigActivity
Starting: Intent { cmp=com.samsung.android.cidmanager/.preconfig.PreconfigActivity }

I see only short Preconfig Window white/empty... but close automatic... so blocked IMHO by some more Security crap...

B

Normal Code input not work for me... so used cool APK since Years very usefull.

But only 27262826 opens correct Preconfig Screen...

Other Codes leads to Errors like on Screeenshots visible...

Remember my SM-A202F is rooted with Magisk...

C

Short checked with Keystring_factory_FB.apk... taken from any Combination Firmware blabla...

No luck with *#27262826#

But for instance with *#197328640# not working in normal "Keypad"...

Only as info...

It is ADVANCED secured against easy Hack...

Only advanced way(s) could work on GW4...

Depend on Firmware Version because we are EVER behind Samsung...

That is the point. There is no CSC code for GW4 yet...and probably will never be. My theory is that using the CSC borrowed from either the SM-R825F or R845, COM versions, it would be possible to acivate LTE services in Colombia. Or perhaps the Chilean version of the GW4(which contains the Multi-CSC OWO firmware) could have it hidden into its files. Have had zero luck trying to download with Bifrost(error 400)

Tiny summary about CSC Change attemptS and crippled Knox Support...

A

Attached Video is taken on GW4...

Alliance Shield X is cool App...

I was able to learn alot with my SM-G920 and SM-A202F ...

A.1

Alliance Shield X need for successful work with Knox feature...

Warranty Void should intact...

Mandatory is Account on Alliance Shield X site... for full working...

My Activity Bypass only for Education... for quick test...

A.2

Tests with remove APKs... leads to conclusion...

GW4 crap minimum not have mandatory:

KLMS Agent...

Download KLMS Agent APKs for Android - APKMirror

Download KLMS Agent APKs for Android - APKMirror Free and safe Android APK downloads

www.apkmirror.com

This is why Tizen Devices are listed as supported Devices under Knox... for few Features:

Device Compatibility Knox Solutions | Samsung Knox

See which of Samsung’s flagship smartphones, tablets, and wearables are built on the Knox platform. Knox is currently available on most Samsung Android and Tizen devices.

www.samsungknox.com

And GW4 00000000000

And now I know what user meant as he told me no MDM support...

Wear OS is listed but NO device yet...

B.

I tried many things with ADB with no success...

Also no success with Codes for Hidden stuff ...

Also found Google Phone Go which I was able to install... no success

Conclusion...

For CSC Change maybe Professional Tools like Z3X ...

Or somebody found the "ADB Commands"... or maybe AT or whatever they use...

From this folder in a file explorer. i use mixplorer app. I have root on my N20. i dont know if it works for non rooted phones.

i copied it at another safe place when i had last firmware update . It will only be presentin a folder named FOTA. when watch downloads new update on your phone .

I dont know . but i would advise not to flash as for daily use. The new Samsung security will block your device from any further updates in future if its not your CSC firmware. it is not worth it.

The USB pinout given by adfree in this thread is correct if you switch data - and + !

Interesting fact: If you charge the watch on the charging puck and connect the USB while watch is normally booted. And disconnect the watch from the charging puck, it will keep on charging through the USB. But when you connect the usb while not being charged by the puck, it wont start charging.
