Update 09/29/20:
1. The latest Samsung Health Monitor Version 1..1.0.175.Caravana (Thanks Caravana for the Mod) Download

This tutorial should work on all Android Phones to enable ECG for your Galaxy Watch 3 and Active 2. BP might also work the same way when it is released in the US.

Basic idea is to create your own certificate to sign ECG.tpk application and install it on your watch, then install the Samsung Health Monitor Mod app on your phone.

I have read lots of threads on XDA and can't find a complete tutorial about how to do it for Galaxy Watch 3 or Active 2. Hope this step-by-step tutorial will help. The whole process took me around 30 mins, it shouldn't be very hard. Make sure you back-up your watch first, just in case anything goes wrong and you need to restore data.

You will need an Android Phone, a Windows PC and Galaxy Watch 3/Active 2 watch for this tutorial. And a wireless network.

Downloads:
1. Download Java for Windows offline (64 bit) https://www.java.com/en/download/manual.jsp and install it.
2. Download JavaSE/Oracle JDK https://www.oracle.com/technetwork/java/javase/downloads/index.html Click "JDK Download" from the top the latest version, then it will direct you to a new page, find "Windows x64 Installer" click the download page from the page and install it.
3. Download Tizen SDK https://developer.tizen.org/development/tizen-studio/download Download Latest Tizen Studio with IDE installer, click "64 Bit" to download and install it.
4. Download ecg.tpk, BP.tpk, Fit2Installer from here(ecg_downloads)

4. Reboot the watch. Make sure wifi is connected after the reboot.

From Your PC:

2. Scroll down to the Tizen SDK tool and click the install icon
3. Click on the Extension SDK tab
3.1 Click the arrow on Extras

6.6 Now it will show your certificate has been saved at C:/Users/USERNAME/SamsungCertificate/cert_name and click next.
6.7 Create a new distributor certificate and click next
6.8 Do not change Privilege and password information, do not close these windows, just leave it there, we need to enable debug mode from the watch and connect it to PC now.
7. Open Tizen "Device Manager" from the PC.
8. Click the "Remote Device Manager" icon from top right corner.
9. From pop-up windows, click the "Scan Devices" icon from the top right corner.
10. Once it find your watch turn the connection switch to on. and close pop-up windows. At this time, you should able to see lots of debugging information from Device Manager. (If you don't see debug information, try these steps: 1. Turn off your windows firewall 2. turn off bluetooth&GPS on your watch 3. reboot your watch )
11. Go back to Tizen Certificate Manager, step 9.8, we can see one DUID has been added automatically. Click next.

13. Download Fit2installer.zip unzip the whole folder to your desktop.
14. Go to the certificate(C:/Users/USERNAME/SamsungCertificate/cert_name) you just created and copy all files. inside the folder
15. Go to C:\Users\USERNAME\Desktop\Fit2Installer\cert Paste all the certificate file you just copied.
16. Copy ecg.tpk file and paste it at C:\Users\USERNAME\Desktop\Fit2Installer\sign_me
17. Click sign.bat from the Fit2Installer folder. Enter your certificate password.
18. It will show "Package( C:\Users\USERNAME\Desktop\Fit2Installer\install_me\ecg.tpk ) is created successfully." and enter any key to close the window.
19. Now go to "Device Manager", right-click your device, choose "install app", Select ecg.tpk file from C:\Users\USERNAME\Desktop\Fit2Installer\install_me.
20. Wait a few seconds, you should see ECG app has been installed on your watch. Open it.
21. Open the "Samsung Health Monitor" app from your phone, you should be able to read the ECG data from your watch now.

As Blood Pressure has not been released in the U.S, once it released, you should be able to activate for Non-Samsung phone the same way. You can disable debug mode if you want now.

Enjoy!

I have used the BP.tpk from this thread and after signing the tpk the transfer to the watch works! I have already calibrate the watch with a blood pressure monitor, all works well!

Working BP.TPK for Non-Samsung Phones

Does anyone have a solution to get the blood pressure app working on an Active 2 with a non-samsung phones? I keep getting the Error -1 when trying to push it to a Pixel 5. I've gotten the ECG app to push, but not the blood pressure. Does anyone...

@anilthakurta try this tpk, maybe it works for you as well!

Questions never make one a fool... always ask and learn... which SHM version are you using... and explain what you mean by ECG is not working with SMH...

Watch SMH is still in English, Samsung didn't start working on releasing different languages for BP and ECG yet...

As for SH and SHM, Samsung still did not fully integrate it yet... in my opinion, when SHM is fully rolled out, they will start integrating SH with SHM for cloud backup and translating the widgets of SHM of the watch...

I updated my SGWA2 to 5.5.0.2, and installed caravanas SHM apk, hoping it would work with the 5.5.0.2 update to give me the ECG function.
The ECG icon showed on the watch for a moment, then disappeared.
Caravanas SHM tells me there is no watch to connect to.
So, could I still go through the instructions in this post for the watch, or will that cause problems, mow it's on 5.5.0.2?

And might there at some point be a modded SHM apk that will work with 5.5.0.2?

My phone is a Huawei P20 Pro.

I'm in the UK, but thw SGWA2 was bought in the UAE. But they have certified the ECG at the same time as the EU, so the update would allow the ECG to function - if I had a Samsung phone...

My watch is as well on the 5.5.0.2. I'm located in Germany and bought the watch in Germany. Try to go thru the instruction from the initial post. It should be worked!

On Mac I've been able to generate my certificate, but the tool to sign is for Windows only.

How can I sign the tpk on mac?

Thanks, SirPhilippF - did you do the modifications in this post before or after your watch updated to 5.5.0.2?

 

[eloisant]

OK, found it:

~/tizen-studio/tools/ide/bin/tizen package -t tpk -s <profile_name> -- BP.tpk

Then to install:

~/tizen-studio/tools/sdb install BP.tpk

I did everything after updating my watch to 5.5.0.2

My watch is 5.5.0.2 and all versions work but my guess is the new versions have something to do with the android version and phone and currently working on makingit work... but in general, the process of installing and doing everything is very simple...

On Mac I've been able to generate my certificate, but the tool to sign is for Windows only.
How can I sign the tpk on mac?

Install a VMware and install windows on it, that way you'll have a windows inside your machine to use whenever you need windows and if you always need windows then I suggest having 2 boot partitions, mac and windows...

Hi
I'm stuck on step 9. I click on scan Devices. As you can see it founds a device with name 'new ' ( is that correct or it should recgnize the watch name ? ). I click on connection but nothing happens.

Both watch and PC are in the same wifi network, bluetooth and gps off.

Other thing, the SHM says no compatible watch found, but i have the watch paired .

Any ideas ?
Thanks in advance.
