Signed or not the monitor.apk doesnt install on Android 11 here.

The previous version by Caravan installs fine

My pixel 3 does run on Android 11 and it works fine.
Could you please add more details, so we can start investigating why it's not working on your phone.

I want to note, that you should uninstall any previous version of SHM before installing the new one.
Are the signing keys you've used to sign the apps the same?

Could you please spend the output of the adb logcat command while you are trying the BP/ECG feature?

On a Pixel 3XL: Worth noting I installed the app on my watch first, then installed the apk from Aptoide, calibrated it and it's working just fine. No modding or anything.
So
1. Install to watch first
2. Install APK second
3. Open app and calibrate.

I'm getting accurate readings on it now given I have my own BPM monitor as well. To calibrate it you gotta have your own BPM cuff to enter a baseline reading. The hardware on the Pixel doesnt exist, so you need to do that. 30 bucks at your local pharmacy and you can get your own BPM cuff if you're really wanting this working.

But all in all. The above method worked just fine for me before I undertook the method here (YMMV of course for other phones, I can only speak to Pixel 3XL)
Could you share your apks files? Have you got the last Samsung update Tizen 5.5.0.2? Thanks

Not necessary....because i is full of win :)

As i said, i decided to start with a clean slate so i wasnt wasting anyones time...god knows i have about 2 updates and a few gremlins since i first enabled ECG and BP late last year...so i:

  • backed up my watch data to my samsung account (save yourself a lot of time folks)
  • reset the watch
  • restored my watch data
  • started over as per the original guide, from scratch tizen studio and all...created new certificates...
  • signed the original ECG and BP tpks as i did last year (not using the latest ones here)
  • reconnected the watch to my phone (with new (signed) samsung health monitor on it)
  • tested ecg = good
  • tested bp = good...no connection issues...goes all the way through calibration...win
So the only thing i did differently from the 1st time was use the latest Samsung Health Monitor apk from last few pages, and only because id already figured out how to sign and install it before i reset the phone. Im certain the original old Caravana SHM would have worked just as well. So the connection issue was most likely to do with the watch, which as ive said has had its share of updates and gremlins since i first did it - oddly not for ECG....

Also did not use the recently posted bp or shm tpks

Maybe i will try with the updated bp and shm tpks in a few days and see what happens....think its obvious you dont need the latest bp or shm tpks to have it all working, but will be interesting to see if they work or not...few people saying they dont

When in doubt, reduce the risk of sending everyone in the thread crazy and wasting their time, and reset and start over. If only more people did it :) :)

Cheers for your eagerness to help though @l0nax



p.s. Also having continued luck with Samsung Pay working just fine on my rooted Pixel 2XL. Nice when all functions of the watch work on a non Samsung phone

Hi all,
I'm leaving in France and received the official feb 22th Tizen update on my both watches, GWA2 and GW3.
So I uninstalled the moded SHM apk and installed the "official" one without any problem.
I use Samsung S21 Ultra.
But I'm facing a strange problem :
I can only calibrate ONE watch (no matter which) for BP, but the second watch calibration stops and force close SHM after the 2nd step!
Then SHM keeps force closing and i have to clear data to make it work again (and needs to calibrate (one!) watch again)
Any helps would be very appreciated, I'd really like to use both watches for BP!
Thanks in advance.

Some time has passed so any clue please?

BTW, just a recalibration does the same thing. Not related to multiple watches, though.

What id love to know next: where the BP calibration data is stored and potentially back it up, as a ROM tester, clean flashing means recalibrating BP all the time is going to be a pain in the bott bott
Well as I recall, from version 175 to 183, the encryption changed, I didn't really pay attention to the storage as I was investing the integration between SHM and SH after patching and fixing the latest SHM to be fully compatible and working with all phones (SDK24 and above) and regions...

So the encryption of SHM basically assigns an ID to the watch, if you reset your watch or tamper with the watch SHM, the ID is changed and thus, SHM on your phone would erase previous data and start over again, so even with with the backup of SHM data, you can't use...

It might be bpvault.db?
i do recall seeing the word vault db but I don't remember as it wasn't my target...
That is what I can tell so far...

Edit: since you flash your device a lot, try to maintain the same Android ID, it might also be related...

SHM TPK 39...

Compared with 37 I can not see much...
No languages added...

Maybe Bug(s) fixed or Security increased...

Best Regards
Thank you for the share...
It's mostly visual fixes, so I'd say bugs...
Services were not touched when I compared them, no security added...

SHM builds a database for one watch only, if you're using 2 watches, you'll end up with SHM crashing, and you don't need to do much to be honest for SHM to fail, SHM has a broadcast receiver listening to Bluetooth connections expecting a watch with SHM on it, so if you have both watches connected, they will one way or another interfere...

    i would like to share mine..

    SM-R820 Galaxy Active 2 Under Armour Edition. i am from singapore and my CSC is XSP.

    It works for me after following @Dante63 instruction the "Easyway"
    Uses the following:
    1. SHM 183 Modified
    2. Samsung BP Installer and Samsung ECG Installer
    for BP watch data seems not syncing with Samsung Health but everthing else works.
    2
    I have Active 2 and I managed to install BP as well following the video below, using the apkeasy tool:
    However BP is not being synchronized with samsung health app, only ECG

    BP doesnt sync for anyone

    Update:

    i was wrong, since i last looked a trick for enabling it has been posted: https://forum.xda-developers.com/t/...-restriction-removed-11th-april-2021.4202685/

    Just tested it and confirmed working!
    1
    I didn't know Active 1 can measure, it should be active 2 and galaxy watch 3 and any futuristic watches
    SM-R500 can do it, maybe using My BP Lab app. I'm not sure about the app, but i'm sure it can do it.

    @ah_cleo i think i have installed the same files as you. modified shm .183 and BP installer, but i'm in your same situation
    1
    Just as an FYI, I have installed the modified shm on my galaxy watch 1w 46mm.
    Using the tpk pushing apk files it has installed the ecg but not the BP. That being said I can't use the ecg as it says to lightly rest your finger on the top button... Mine won't register the touch?
    Any advice would be great

    UK sm r805f
    Tizen 5.5.01
    Galaxy watch is not equipped with the ecg probe hardware, your button is just a normal button...
    1
    SHM 175 doesn't have many features, export your BP & ECG so you can update your SHM to 189, unfortunately updating immediately won't work because the database and everything has been recreated, there is no compatibility between 175 & 181++... You can update and clear the data or uninstall 175 & install 189...

    No need for logcat...
    Updated SHM, it syncs now, thank you very much 👍🏻

    UPDATE 10.06.2020: Version 165 from @[SIZE="4"]adfree[/SIZE] and modded by @[SIZE="4"]caravana[/SIZE], with this version you can update WITHOUT deinstalling old one and without make calibration again. Try it and let me know. Download from here: AbsolutelyOWNRISK-APK-165

    UPDATE 07.06.2020: New APK again (version 161). Always thanks to @[SIZE="4"]adfree[/SIZE] and @[SIZE="4"]caravana[/SIZE]. Download from here: AbsolutelyOWNRISK-APK-161
    UPDATE 30.05.2020: New APK (version 159). Thanks to @[SIZE="4"]adfree[/SIZE] and @[SIZE="4"]caravana[/SIZE]. Download from here: AbsolutelyOWNRISK-APK-159
    UPDATE 17.05.2020: I updated the APK with version 157 (thanks @[SIZE="4"]caravana[/SIZE]) because the old one gave a false-positive with MalwareBytes app (RUBBISH).


    Okay, I'm going to explain all the steps I've done. I will try to simplify driving to the maximum.
    In attached you will find the APK and the TPK that I used (the credits for both go to those who upload them in the forum; thank you very much), and old version of SDB (2.2.6.0).

    Of course, everything will be AT YOUR OWN RISK, so you need to know what you are doing!

    0) Enable debugging and "Developer Options" on the GWA2, activate WiFi (same network where the PC is connected, the guide concerns only Windows, sorry for this)
    1) Download the attached files and dezip it
    2) Download and install TizenStudio 3.7 with IDE installer (608MB)
    3) Start TizenStudio, at the top you will see a box with "No target" written, click on the drop-down menu and choose "Launch Remote Device Manager" click on "Scan" and you will find your watch.
    4) Click on "Connect ON" and accept the connection on the watch. Once connected, open the folder containing SDB 2.2.6.0, CMD, "sdb install bp.tpk"

    If you have installation problems you have to try these ways
    - on the watch activate wi-fi, deactivate bluetooth, restart the GWA2, retry steps 3) and 4)
    - if you have not solved, you must reset the smartwatch, re-associate it with your smartphone and repeat steps 0), 3) and 4).

    Hey everyone,

    The last few days I've sad down reversed engineered and patched the Applications.
    I toked my a while, but I got ECG and BP working with the latest SHM-Version.

    Some facts about the Hardware & Software I used/have:
    • Samsung Galaxy Watch 3
      • Model: SM-R840
      • Tizen Version: 5.5.0.2
      • Software-Version: R840XXU1BUA8
    • Google Pixel 3 (Android 11)
    • Location: Germany
    Samsung Health Monitor Versions:
    • Android: 1.1.0.183
    • Galaxy Watch: 1.1.0037

    Please note that at this time I do not have the device to calibrate the Blood Pressure feature.
    But this evening I will have access to a BP Device, I will update this post after calibrating the watch.

    New tpk pusher with v1.1.0037 ;)

    Hello everyone,

    As we have no users from Korea as it seems...
    No idea why...

    I'm from Korea :eek:

    First, thanks for your great work. Now I'm using BP feature with my galaxy watch active 2 using your guide.

    I have a Korean Galaxy Note 10+ (SM-N976N) and Korean Galaxy watch active 2 (SM-R820, R820XXU1BTD6, CSC=KOO, Tizen 4.0.0.8).

    I could install the BP version 1.0.72 (samsungapps-000004413020-2035556-100000072.wgt) and ECG version 1.0.0004 (samsungapps-000004688049-2651158-100000004.wgt) and SHM version 1.0.0.165 (Samsung Health Monitor 1.0.0.165.mod2.apk),
    but unfortunately I still couldn't get the ECG feature..

    ===

    There was no ECG debug menu on *#0*#.

    ===

    I analyzed the decoded APK + disassembled JAVA code for SHM version 153 and 165, and I couldn't find the ECG logic.
    There was no code for "com.samsung.android.shealthmonitor.ecg.control.EcgController" class which is called from ControlManager.
    Of course the "com.samsung.android.shealthmonitor.bp.control.BloodPressureController" class could be found in the folder.

    ===

    Finally, there is a Korean website of "Ministry of Food and Drug Safety"
    https://emed.mfds.go.kr/#!CECAB01F010

    You can find the BP and ECG approved number by Samsung if you can translate Korean...
    1. Type 삼성전자 in 업소명 field (find samsung electronics in company name)
    2. Click 제 2893 호 (company number 2893)
    3. 제허 20-295 호 (approval number 20-295)
    -> This is for current BP app.
    -> Classification Name is 혈압 검사 또는 맥파 검사용 기기 (Sphygmomanometers and sphygmograph). You can find this one as "home_about_label_classification" in strings.xml.

    4. 제허 20-378호 (approval number 20-378)
    -> This is for (maybe not released) ECG app.
    -> Classification Name is 심전계 (Electrocardiograph)

    153 version didn't include both of 20-295 (BP app) and 20-378 (ECG app)
