Dear all, if I upgrade firmware to smR890_EVA8_OXM_v1 I can change to any region I want?
[Samsung Galaxy Watch 4] adfree:
@vendn

If you have ABC Power and you can count from 0 - 10...

Then EVA8 is not latest...

Remember Samsung Rollback Prevention Crap...

So IMHO better NOT downgrade... to prevent """magic"""...

Only if you know what you do...

With my third GW4 SM-R870... EVA8

I realized Code *#0808# is blocked in CSC DBT...

If I switch to BTU I can enter USB Settings...

B

No luck with any kind of old "magic" in EVA8...

No CSC change no FOTA Manager etc...

Still no access to /cache/fota

blabla...

So all things not work since EVA8...

C

I have only 1 Key... the Power Key...

So I have to prepare few things before I can do stupid tests...

For instance to leave Fastboot Mode I was forced to use Screwdriver... to leave this Mode...

Because Key is absent...

D

The second GW is also SM-R870... but seems dead dead... no luck...

I will try to solder wires... mabye lifesign... but...

Short tried to install APKs from Combination Firmware...

But all seems marked as Factory crap...

D:\Android\ADB>adb install BluetoothTest.apk
Performing Streamed Install
adb: failed to install BluetoothTest.apk: Failure [-3001: INSTALL_FAILED_REJECTED_BY_BUILDTYPE]

F

I am in Standalone Mode... to prevent Firmware Update...

I need EVA8 for stupid tests...

G

Rumour maybe downgrade possible... but seems to create trouble...

BT address gone... no pairing

FOTA Registration failed... so no Firmware Update possible...

This is at the moment the only way worked for me to change CSC like I wish.

Edit 1.

com.sec.android.app.parser android- DRParser Mode

What is com.sec.android.app.parser android- DRParser Mode? How to bypass FRP? How to fix DRParser mode not working? What are the cheat codes?

Edit 2.

I will check what happens if I "uninstall"...

freshbl:/ $ pm path com.sec.android.app.parser
package:/system/priv-app/DRParser/DRParser.apk

pm uninstall -k --user 0 com.sec.android.app.parser

Looks like htis to me:

freshbl:/ $ pm uninstall -k --user 0 com.sec.android.app.parser
Success

@mrfatiga22

We can do few steps together...

For me I did with SM-R870 and help of SM-R860 because I have more then 1 GW4...

I have no idea which GW4 you have?

So my Quesion number 1 is:

A

Your Model Name?

B

Firmware Version...

Easiest way:

*#1234#

Because IMHO you need Kernel for coressponding Firmwareversion...

We have only old Firmware Leaks and only for BT only devices...

¡¡¡¡Muchas gracias!!!! Con esa respuesta ya me ha ayudado mucho, y me siento motivado a seguir investigando. Tengo el GW4 BT.

Modelo SM-R870.

Firmware R870XXU1FVC8.

Entendiendo que es un procedimiento complejo, pero me encanta el tema, y por suerte pudo rootear varios Smartphones y algunos Smartwatches como el Lemfo Lem X con Android. El tema es que lamentablemente NO se ingles y me ha metido un poco mareado con esta publicacion, (mucha informacion desordenada). Pero voy a revisar nuevamente las publicaciones, y si no molesta a @TheIntruder , haré una nueva consulta. Muchas gracias otra vez.
