[Samsung Galaxy Watch 3] Zico 10:
It has been released in Australia as of two weeks ago,

Upgraded Health and Personalization Features Come to Galaxy Watch, Galaxy Watch Active, Galaxy Watch Active2 and Galaxy Watch3

Samsung believes in putting the very best mobile experiences into the hands of as many people as possible, which includes our commitment to providing

news.samsung.com

But doesn’t work for me because the ECG/back button is faulty, and Samsung are f’ing terrible with the support. I give them a whole bunch of info and they just reply with “ECG is not available in Australia” and close the support case.

Even when I send them the link on their own website which shows that it is available, they still respond the same way and close the case without giving me a chance to respond.

I f’ing hate Samsung so much, really regret having bought this POS. I can’t wait for someone else to make a decent smartwatch for Android. I’ll toss this in the trash right away if a decent Pixel watch we’re released for example.

I know the project has been dead for a long time, just giving it a shot by posting.

With the latest Samsung Health app has the blood oxygen module by default now, would porting the SpO2 wgt to the GWA2 would get it functioning?
[Samsung Galaxy Watch 3] gr8sk8:
Have you or anyone tried side loading the SpO2 wgt to the Active2 since the update to Samsung Health? I'm going to give it a shot, but wanted to ask first in case anyone has already tried all that. Thanks for keeping hope alive, lol.

Next move about Blood Oxi...

Compared SM-R840 BDG6 and SM-R820 CTI4

Replaced w-manager-service from BTG6...

sdb push w-manager-service /usr/apps/com.samsung.w-manager-service/bin/

I am not 100 % sure if accepted in this easy way... but i can't see sideeffect.

But also I can not see Blood Oxi... :D :o :rolleyes:

Next attempt is... complete com.samsung.w-home replace...

IMHO I am sure to see effect, if Signature is verified... :D :rolleyes:

Tiny progress...

I was able to force the Widget... by modified Shealth TPK...

But if I press Measure...

Not supported in your Country...

Double checked by installing unmodified Shealth TPK 4.13...

No Widget...

Trick was easy...

Triple checked in .home.db

[B][COLOR="Red"]u[/COLOR][/B]xygensaturation

:D :D :rolleyes:

2 files...

tizen-manifest.xml
shealth-widget

Now really this as next attempt...

Is it the country from the watch region data or Phone country data ?

Can you share tpk ? will test it from here
[Samsung Galaxy Watch 3] adfree:
At the moment all tests with Standalone Mode... without Phone...

To prevent more Security crap...

At the moment all I share are infos...

Its still experimental and I waste tooo much time...

A

Most Copy and Paste Action...

B

In main I "hack" text strings...

[COLOR="Red"][B]u[/B][/COLOR]xygensaturation

C

Without my rooted Firmware you can not use my modified TPKs...

About today progress...

sdb root on

sdb shell mount -vo remount,rw /

sdb push w-home /usr/apps/com.samsung.w-home/bin/

In w-home I changed again only text string...

Now unmodified Shealth TPK creates the Oxi Widget...

I can not more screen capture series of Pics nor Video...

Samsu.g f%&ing changes to working stuff su..xx

https://xdaforums.com/showpost.php?p=79453197&postcount=755

Need to find new workaround... :rolleyes:

Next move is to try replace full

com.samsung.w-home

Yeah I know harhar... :eek:

But it is not so easy... no idea if files from GW3 crashes on SM-R820...

Best Regards

Edit 1.

sdb root on

sdb shell mount -vo remount,rw /

sdb push whome_BTG6.zip /

sdb shell

cd /

unzip whome_BTG6.zip

Leads to black Screen...

Now i am trying to Factory Reset...

Edit 2.

Seems incompatible with SM-R820 or I made mistake with SQLite Database crap and/or File Permissions.

Anyway... I have to fix by using netOdin... and flash rootfs.img
[Samsung Galaxy Watch 3] betterl8thannvr:
Any idea what causes the black screen? I remounted / as RW today, made some changes but reverted them, and still got the black screen. Wifi download won't even work for me, so I am going to have to make a USB cable and go to Odin mode (WARRANTY_VOID is still 0! Of course my watch is old, and I think out of warranty now)
[Samsung Galaxy Watch 3] adfree:
[MENTION=11155683]betterl8thannvr[/MENTION]

Security for instance...

SMACK crap and other AntifunAntiuser mechanism against playing with Firmware...

Example...

If I play with f%&ing SQLite Database and Reboot... then Black Screen, but Wifi still possible...

Tizen is booting proper...

Solution is to flash rootfs.img and csc.img to force some update function...

Sorry, no idea what exactly you did...

Also File Permissions are deadly if wrong...

Yes, for instance...

We could choose between different methods to nuke this...

IMHO only 3 folders affected...

KOO
XAR
ZTO

[csc packages]
count = 2

name_001 = "NaverMap"
type_001 = "wgt"
description_001 = "path=/opt/system/csc/app/NaverMap.wgt:op=install:removable=true"

name_002 = "Samsung Health Monitor"

We could edit... so we can remove if want...

Or we can fully delete such files... including the TPKs...

Is there an emulator for example we can use to load the rootfs and run the application from there. A sample setup would a be linux box with the arm toolchain. I remember doing this for an ARM busybox on a Virtualbox Linux

Here some files and infos for research... custom csc.img related...

I got my watch today and am on the newest update but have no SPO2
[Samsung Galaxy Watch 3] EQMOD:
Where can we download version 4.13 ? Looks like you will be the first guy with a picture of an Active 2 with Spo2 in it :)
[Samsung Galaxy Watch 3] adfree:
Autsch...

4.13 is maybe better secured but runss on my SM-R820...

So tried with BTG6 Firmware from GW3...

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<manifest xmlns="http://tizen.org/ns/packages" api-version="5.5.0.1" package="com.samsung.shealth_gear" version="[COLOR="Red"]4.10.1700[/COLOR]">

Will check this Version...

4.10.2600
[Samsung Galaxy Watch 3] EQMOD:
From logcat maybe it shows some lib modules not loading ?
[Samsung Galaxy Watch 3] EQMOD:
Usually if you migrate code from one platform (GW3) to (GA2) for example, although same compatible arm cpu, if one application designed and compiled for GW3, if you need to run it on GW2 , sometimes you need to include the lib files with it, and create a directory for those libfiles like libsp02.so and so on , point LIBPATH to include that directory :) Typical linux stuff way of executing applications compiled from a different platform :)
[Samsung Galaxy Watch 3] necrohiero:
Hmm. I know it is maybe out of topic, but could you point me in the direction of how to do this? I have german Active 2 Watch, and would like to activate BP and ECG. (And how to revert back)? I have an Huawei Phone too (P20).

I tested again under Standalone Mode...

No Reboot require for Blood Oxy in menu...

Reboot mandatory for w-home to apply... then Widget enabled...

Please try again to push shealth Binary:

sdb push shealth /usr/apps/com.samsung.shealth_gear/bin

This is the "menu" hack...

No reboot require. After push you should see it...

Maybe close all apps, Shealth should not run...

Hi dear friend @adfree

First thank you for your kindly attention

As you know in tizen 5.5.0.1 the battery does not have a long life but i wanted to have blood oxygen so i flashed CTI4 on my R830 and then i rooted my watch and finaly push all of your 4 file.

Only widget is available on the watch and wearable app but l can't see blood oxygen on samunghealth menu too!

And as you say measuring is not available yet

We need help of GW3 user(s).

To solve the riddle.

Seems Sams.ng did again heavy Security crap and maybe disabled things in GW2 Firmware.

Best Regards

I'm on tizen 5.5 with SM830 and when I run the test I can see the RED LED as I did on 4.0.0.8 so no change when upgraded to 5.5. By the way I can see infrared light too if I point a camera at the back of the watch.

Seems I am blind.

If I do it in normal way...

I see only tiny red 1 point LED... very tiny... inside the big green LED...

:o

User told me trick to see big RED LED on my SM-R820 CTI4.

WARNING!

OWN RISK!

No idea if good to Sensor.. maybe risk to damage...

During the Testmode...

*#0*#

HRM ---> EOL test...

cat /sys/class/sensors/hrm_sensor/hrm_led_g_ir

I made tiny Batch file... to do it rapidly without typing... :D

Execute during EOL... I can see big RED light. :cyclops:

Again.

Own risk.

I will check this too on my SM-R500...

Best Regards
