@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:
Code:
*#1234#


Because IMHO you need Kernel for coressponding Firmwareversion...

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

Best Regards

[USUARIO=11317145]@mrfatiga22[/USUARIO]

Podemos hacer algunos pasos juntos...

Para mí lo hice con SM-R870 y la ayuda de SM-R860 porque tengo más de 1 GW4...

No tengo idea de que GW4 tienes?

Asi que mi pregunta numero 1 es:

A
¿Tu nombre de modelo?


B
Versión de firmware...

La manera mas facil:
[CÓDIGO]*#1234#[/CÓDIGO]


Porque en mi humilde opinión, necesita Kernel para la versión de firmware correspondiente...

Solo tenemos fugas de firmware antiguas y solo para dispositivos solo BT...

Saludos
¡¡¡¡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.

Translation:
Thank you very much!!!! With that answer you have already helped me a lot, and I feel motivated to continue investigating. I have the GW4BT.
SM-R870 model.
Firmware R870XXU1FVC8.
Understanding that it is a complex procedure, but I love the subject, and luckily it was able to root several Smartphones and some Smartwatches such as the Lemfo Lem X with Android. The issue is that unfortunately I do NOT know English and it has made me a little dizzy with this publication, (a lot of messy information). But I'm going to check the posts again, and if it doesn't bother @TheIntruder , I'll make a new query. Thank you very much again.

Also, XDA uses English as offical language on the forum. You can use your native language, but English translation must be posted together. You can use translator site as Google Translate to do the translation.

hello,can you help me a little please? for smR880 there are 2 files. Do I have to join them somehow? On another watch, I put 1 file in Odin, in AP and it worked.Thank you
Firmware these days comes in 3 or 4 pieces. AP, BL, CSC, and (for cellular models) CP.

I have a source who can get me any Samsung firmware (for USA models at least) but he charges for each one

Few users are not able to extract splittet 7Zip Archive...

I have no idea how to help...

I am using Windows PC and Tool 7Zip...
And I can extract TAR from 7Zip...
Code:
smR880_EVA8_OXM_v1.tar

NO Rocket Science... IMHO Computer Basic...

1 TAR because easier for me...

Still old netOdin NOT support lz4 Compression...

Few other users have problems... as Tool extract also TAR... so many files...

Similar problem...

BASIC Computer knowledge...

Look what is inside...

Try different Tools... different Computers...

Ask family friend or neighbar for help...

Summary.

No Rocket Science

Free Files for:
SM-R860 EVB4

SM-R870 EVA8
SM-R880 EVA8
SM-R890 EVA8

are here:

I wrote yesterday or few hours ago Conversation formerly known as Private Message...

Are you able to see this and can you please answer Conversation...
(Upper right Corner near your nickname...)

Then we can try to solve your problem...


My last aller last Option is to reupload 1 Single 7Zip *.7z

Better solution is. User is able to unpack alone at home... with existing files.

Code:
smR880_EVA8_OXM_v1.7z.001.abc
smR880_EVA8_OXM_v1.7z.002.abc

You downloaded 2 files with fileextension:
Code:
.abc

Now use Himmel and H.lle to rename these 2 files into 7Zip valid... because they are splittet... 1 Archive splittet into 2 files...

Goal 1 is to rename to:
Code:
smR880_EVA8_OXM_v1.7z.001
smR880_EVA8_OXM_v1.7z.002

Now IMHO valid to unpack for 7Zip Tool...

Goal 2 is to extract only the TAR file inside:
Code:
smR880_EVA8_OXM_v1.tar


Good Luck.

    Since Tizen...

    I have never any Watch nor Phone with eSIM.

    So I have 0 own knowledge about eSIM.

    All I "know" is eSIM is more joke... as easy to handle.

    I love my old SIM cards. I can hold them with my big fat fingers.
    I can cut them if they are tooo big after 20 years...

    eSIM sounds more pia... with all this Security Region Lock crap...

    Sorry, my private opinion.

    A

    I was able to fix my FOTA Update problem on my SM-R870 and my SM-R860...

    SM-R860 stupid me set something and disabled access to Recovery... only black screen...

    Long time ago I did something stupid...

    Only realized how deadly... as I was not able to finish Update to GVH2...

    Solution for my SM-R860:
    Bootloader unlock... this Reset param etc and Recovery is avalaible again...
    Then lock Bootloader again...
    Knox NOT dripped because nothing flashed...

    B

    My Update Problem with SM-R870 was deeper because rooted...

    Solution for me:

    Bootloader Lock
    Then downgrade via Odin to DUK1... via USB cable...

    Then FOTA worked...

    DUK1 ---> FVD4 ---> GVH2

    And my Root with help of Magisk 24.3 also work.


    C

    I have nothing tested under DUK1... not sure if same result. If flashed EVA8 files to my SM-R870... EVA8.

    But as FOTA work... correctly...


    This means sboot.bin downgrade really work.
    From EVA8 to DUK1


    Only as info.

    No idea when Full firmwares for study leak...

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

    It is possible to decrypt from Test Server...

    Then maybe more clear...


    OXM seems also for DBT ZTO and so on...

    A
    In theory linked FOTA Delta should work for AUGE DBT or SER or ZTO...

    Question is only how to update manually...

    B
    Roll out official could be in waves... but could be also more funny like we allready knows...

    We will see the future of GW4 support.
