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)
5. Download Samsung Health Monitor Version 1..1.0.167.Caravana (Thanks Caravana for the Mod) from here (See update 09/29/20 from the top of the thread to download the latest version)

On Your Phone:
1. Install Samsung Health Monitor Version 1..1.0.167.Caravana on your phone. Open the app enter your name, BOD and etc to finish the setup.

On Your Watch:
1. From your watch, Go to "Settings"->"About Watch"->"Software"->Click On "Software Versio" 5 times until it shows "Developer mode turned on"
2. Go back to "About Watch", make sure it shows "Debugging is turned on", it not click "Debugging" and turn it on.
3. Go to Wifi settings on the watch, change wifi setting to always On, and connect it to the same wireless network with your PC.
4. Reboot the watch. Make sure wifi is connected after the reboot.

From Your PC:
1. Launch Tizen Package Manager and Navigate to 5.5 wearable(It depends on your watch's software version, eg mine shows Tizen Version 5.5.0.1, so I navigate to 5.5 wearable), then click Install icon
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
3.2 Install Samsung Certificate Extension and Samsung Wearable Extension
4. Check the Progress tab, once it shows 100%, you can close Tizen Package Manger and do not launch Tizen Studio(we don't need to use Tizen Studio)
5. Open up "Certificate Manager"
6. Click on the "+" icon and from the pop-up window click Samsung Logo.
6.1 Device Type -> Mobile/Wearable, Click Next
6.2 Certificate Profile(Give it whatever name you like), Click Next
6.3 Author Certificate -> Create a new author certificate, Click Next
6.4 Author Certificate -> Enter Author name, Password, Confirm Password as required(Remember the password,. you will need it when you sign the TPK file) and click next
6.5 A pop up will ask you to sign in to your Samsung account, enter your account information and sign in
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.
12. It will show your certificate has been saved at C:/Users/USERNAME/SamsungCertificate/cert_name, Click Finish.
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!

Is there an IPA file for this that can be sideloaded onto an iphone? I'm no expert at this stuff and have only followed the great instructions here before so not sure. Or is there any way to connect my GW3 to my Samsu g Tab S6 on Verizon that shares my iPhone number? I'd like to get the Health Monitor app features as I really don't want to go back to an apple watch.

Supposedly on tizen 5 there is no bp.tpk - ecg and bp are now both in ecg.tpk. installing old ecg.tpk may be main reason for bp not to work. Did anyone try to follow the tutorial but use new ecg.tpk? Does ecg.tpk need to be specialy prepared to by signed with certificate or can we do it with new ecg.tpk that has been posted by caravana?

Can there be a mess if in the future I change my phone and take a samsung?
Does the smartwatch remain unaffected? Will I always have to update it manually?

Anyone else having issues w the carvana health monitor app? I keep getting an error saying it cant be run on a rooted phone...
hide it in magisk hide section of Magisk manager app.

Also, make sure you're passing safetynet on magisk manager & from manager's settings, enable magisk hide, also hide magisk manager & give it another name.

I can confirm I pass safetynet, I have all samsung related items enabled in the hide section and I've renamed the magisk manager app and renamed it. Still nothing :(

Thank you very much!! @xxstd

I had some problems running "sign.bat" due to relative path command routes, but after "customizing" the script changing to absolute path, all went ok.
I've signed BP.tpk and ECG.tpk and both are running OK in my GW3. I live in Spain, and here in Europe neither ECG nor BP are approved, so it is not the reason your BP tpk is not working IMHO.

I tried installing bp and it failed to install. But ecg worked.

Can you confirm the Tizen version from your watch? I know if you are runing Tizen 4.0.0.8 you could get BP works as well. Only ECG for Tizen 5. :(

Hmm, are you using the latest version Tizen SDK? Mine is Tizen Studio 3.7, they might change the UI a little bit for different versions.

Is there a risk of voiding the warranty or bricking the watch doing this?

Well, as the debugging mode has been enabled, if you tell Samsung they will possibly decline the warranty since they don't know what you have done to the watch...... But you can always turn it off, and reset the watch anytime you want.

    Ok that's what I did and it worked. I have everything installed, only Samsung Health Monitor Version 1..1.0.175.Caravana does not want to connect to BP sometimes tries, but fails. From what I have read it needs to be updated - I have not found in the update settings. With that being said, need to find a newer version of HMS and install?

    Thanks in advance for everything.
    If you searched xda, you'd find my thread with the latest SHM 189, make a backup before you update if you have any recordings you need, Samsung changed everything from 175 so update will require clearing data

    Believe managed to solve the situation by replacing SamsungHealthMonitor167.Mod5.apk for Samsung Health Monitor Version 1..1.0.175.Caravana.
    Thanks!
    I was inspired by this video.

    Hi @Dante63 thanks for your help. I did install jdk 15 and it worked, at least to install the ECG. And apologies but as a new user I'm still getting used to navigating the threads. Going now through the posts one by one (search thread didn't seem to work for me) and if all else fails I'll ask again for your kind help. Still haven't run across your post on jdk 15 so there must be a better way - I'll learn :)
    How do you like your coffee?

    Dante63, thanks for your help and comments earlier.
    My head is spinning - I haven't done stuff like this since the days of Windows Mobile!
    Could you just tell me whether, as I now have 5.5.0.2 on the watch, with ECG and BP in the update, although not available to my Huawei P20 Pro, should I still install the apks?
    Or do I understand that the next SHM you modify might just work with the 5.5.0.2 and the P20 as-is?
    Really sorry, and grateful for any help.
    (The watch is from UAE, but I'm in the UK)
    Many thanks!
    It's already done, I have 175, 181 & 183, but for those who can't get it running, I'm willing to play around with the SHM apk, hopefully I find what is stopping the app from running...

    it's not fair for people having a watch and can't use its features because it's not available or device problems and so on...
    2
    In allegato BP in italiano, da me tradotto, da firmare. perfettamente funzionante in abbinamento a SHM1.1.0.175 anche esso in italiano
    buon divertimento
    2
    I successfully installed the ECG tpk, Dante - works perfectly with SHM 175 - thank you so much!
    To install the BP tpk, do I just add it using Device Manager?
    Because it doesn't want to do it.
    I don't need to repeat any other steps, do I? Just install the tpk using Device Manager?
    Sorry - I've been doing it for ages, and now I'm too tired to think straight... Would like to do it while everything is set up to go.
    Many thanks, as always.
    You can try with SDB or decompile the TPK installer, add the signed tpk file inside the assets and compile it and then install it and it will push the file inside your watch... I hope you get right and at the first attempt...
    Whered you find the bp.TPK file I cant locate it?
    That member used the BP.tpk in my thread...
    2
    I have tested all the versions in you drive link, none work.
    I think it's time to upgrade the hardware.
    I will make 1 more version of the SMH...
    Wait a little bit longer, if that version works, it will solve most of people problems with the latest version...
