sboot.bin from Engineer is not valid so FOTA fail...

Will check if I find newer Stock firmware...
I know we fixed this... but I am sooo lazy...

Best Regards

haha understood, if you can help me id be very grateful :)

maybe there is a newer combination file for SM-R825F like FT55? can you suggest another firmware we could use so FOTA works on BTU?

Thanks guys, appreciate this!

Google search...

R825FXXU1CTK3_Tizen_4File_CSC (OXA).zip


CTK3

Ehm own risk...

Depend on your active CSC if then valid file for FOTA...

But seems OXA Region...

Best Regards
Just tried this firmware - also it locks up on PIN code during setup sequence.

The only one i found which doesn't lock up at the PIN stage is R825FXXU1ASI7, however it finds FOTA updated and attempts to install but after reboot it says "cannot update at, try later"

Again warning about old Tizen 4 Firmwares:

@Tammar2

Evolution 2 Battle for Utopia is at the moment more important to me... so less time...

Tiny hint...

Only SM-R825US Combination firmwareS leaked... NO SM-R825FS...
Similar "problems" for GW3 LTE devices... NO idea why...

BUT "sometimes" it work...

Big difference is Bootloader sboot.bin...

Only as info/sidenote...


If I have time I will check my HDDs... :alien:

Best Regards

COMBINATION-FT55_R825USQU1AUA4_clean.zip

WARNING!

A
OWN RISK!

B
Please only use if you know what you do...

This is in main SM-R825US FT55... because sboot.bin Bootloader is for SM-R825U(S)...

On SM-R825FS Bootloader will be skipped... but could work...
This is Running Gag for LTE since monthS...

C
I have removed folder meta-data... and repack to TAR file with 7Zip Tool...
So no MD5 Hash added...

D
Samsung have Rollback Prevention...
Be sure you have Alphabet skills and you can count from 1 -9 to identify if you can "safe" try...

This FT55 is AUA4

So chance high(er) it is valid for Stock Firmware R825FXXU1CUA5

Best Regards

Hi. I have SM-R825F
I did everything as instructed in the first post. When loading AP Combination, FAIL appears at the end.
The device would not start. fortunately, after uploading the stock firmware from the first post, the device started up. Unfortunately, fail appears on the next attempt to install Combination. Can anyone help me with this?

Hi,

I got up to step 13, the flashing failed at the end in netodin twice, now in wireless download mode it says " (WPS mode) Not connected, Download error detected."

The watch won't setup a wireless AP that I can connect to, the watch seems to be essentially bricked.

Need help!

I got an error after uploading AP. Watch sent to SAMSUNG service. I wonder how much they will take for the repair

    Today I made the calibration with an Arm sphygmomanometer for the blood pressure monitor
    here video:
    Calibration Test
    It seems to work quite well then for the battery it is not that you have to use it many times a day but maybe once.
    About ECG I saw the first measurement went well, then I did other measurements and It went crazy, now I don't know what it is due to.

    So it worked fine for me. I followed all the steps. I got a little bit concerned when I got failed after AP upload, and then when I saw weird icons in the watch, but I completed all the steps and it worked fine. I used BTU as i am in the UK and now I am waiting for network set up. I couldn't do it before. It also updated to the latest software ok.

    Thanks everyone involved in that.
