Galaxy watch activ firmware R500

[adfree]

Success.

With FT40 ATJ1 I was able to downgrade also the Bootloader sboot.bin:
COMBINATION-FT40_R500XXU1ATJ1.tar. md5

All things alive and working... like BT and WiFi...

Now flashing again ETI1... to have all parts valid for FOTA Action... later...
And/or to rebuild ETL2 files.. BL part...

Best Regards

I am now on ETL2...

Will try if I can mix with my Root from ETI1... so I can dump the missing files with dd Command...

Best Regards

Edit 1.
Success.
"Rooted Mix" work... I can proceed with dump whole 4 GB via netcat soon...
I have to charge Battery first...

Jak nastavím FOTA zpět na aktivaci 1? Musím nahrát FW ATJ zpět? Nechci nic kombinovat, ale chci mít například, stejně jako na mém S10 + fw XEZ, chci to na svých hodinkách. Právě jsem nahrál OXA a nejde to FOTA.

netcat working...
Later if 4 GB eMMC dump is finished I can take the missing files with help of partition layout... aka PIT from here for instance:

If nothing bad happens...
IMHO I need 1 or 2 days to test and upload the missing BL files for ETL2...

Step 1.

Successfully done.

Flashed ETL2 to my SM-R500 via netOdin.

Step 2.

Also success... FOTA found to FUB5... CSC XAR...

Now I have to wait for finish

Good stew in this thread. I'm waiting for all three files and not such a combination.

@cardi77

You can wait for what ever you want.

For me it is working.

I am successfully moved from ETL2 to FUB5 via FOTA update... after flashing all 3 files for ETL2.
CSC used XAR

AP_R500XXU1ETL2_usr.tar.md5
CSC_OXA_R500OXA1ETL2_usr.tar.md5

Attached is ZIP...
BL_rebuild_smR500_ETL2_v2.zip

Now use Tool like 7zip to unpack TAR file inside...
BL_rebuild_smR500_ETL2_v2.tar

NOT unpack TAR.

Ignore it is no tar.md5
I am tooo lazy to add MD5 Hash...

Fota update will not find me the latest version of ETL2 and another won't show me a shoda for me this doesn't work: /

 

[cardi77]

What? :/

Only Korea KOO and US XAR have Tizen 5.5.0.1 FUB5...

If you are still on XEO for Poland then ETL2 is still latest...

http://fota-cloud-dn.ospserver.net/firmware/XEO/SM-R500/version.xml

I changed my CSC to XAR to get FUB5...

Best Regards

 

[cardi77]

I never changed CSC: / how do I do this? Thank you

Look at this Video:

BUT use files from SM-R500.

[cardi77]

Too complicated: /

Only as info.

I managed my problems and now I have rooted FUB5 on my SM-R500.

With help of rooted ETL2 files...

Best Regards

update I could try on other RM-500! I found that there are no changes. They just wanted to seal people's mouth with this latest update: x
