Guys which is better german region or korea ?i am in europe,thanks
[Samsung Galaxy Watch] podupuis:
For anyone with CSC from Korea and want Tizen 5.5 with ecg and bp working on a non Samsung phone here is the fix.

Flash the firmware to 4.0.0.6 or 4.0.0.7 and install bp and ecg with sdb install. Install Samsung health monitor on your phone and after that update your watch to the latest version of the watch.

That it! Work great for me. I use a ROG phone 3 with my watch on CSC KOO with Tizen 5.5. ecg and bp is working.

---------- Post added at 06:16 PM ---------- Previous post was at 06:14 PM ----------

Flash back to 4.0.0.6, flash ecg and bp. Update your watch after. Work great for me. I'm on Tizen 5.5 with ecg and bp working. CSC KOO.
[Samsung Galaxy Watch] Rafaelcastro85:
what files?

23.tpk or egc.tpk / bp.tpk?

what's your watch?
[Samsung Galaxy Watch] podupuis:
23.tpk wasn't working for me. Use the ecg/bp combination. Flash bp first and ecg after.

I have the active 2 model sm-r820.
[Samsung Galaxy Watch] mitas35:
Anybody manage to install the tpk on 5.xxx? I don't have any bp or ecg ,i am on active 2 korea ,:(
[Samsung Galaxy Watch] Bi0haZarD:
I confirm this is the only process that works also for me on a non samsung phone, (i'm using xiaomi) but keep in mind that if for any reason you reset the watch, bp and ecg will be gone just like that, poof...and the only way to get them back, since it's still impossible on Tizen 5.5.0.1, is to repeat the whole process of going back to either 4.0.06 or 4.0.0.8 sideload the separate BP.tpk and ecg.tpk and then update again to Tizen 5.5.0.1

Yes, i've been through this cumbersome process myself, just to find out the same thing like our friend podupuis

Device: GWA2 SM-820 original CSC EUR (Greece) changed first as XAR, then to KOO

This is it!

i had been pulling my hair out since the last week trying to get bp and ecg work on my watch active 2 after changing csc to usa first then korea. nothing worked so i just updated to 5.5 and called it a day. read this post and downgraded to 4.0.0.6 and installed bp and ecg. ecg installed fine but bp would disappear after a second. procured bp.tpk from somewhere else and installed again (after deleting the previous invisible one using sdb shell command). this time it worked. now i have both bp and ecg running on my watch and oneplus 7 pro. updated to 4.0.0.8 and its working here too. will post an update after updating to 5.5.

Thank you so much bruv!!

[Samsung Galaxy Watch] rasputine:
i can confirm this step work for me.

i have Google Pixel 3 and GWA 2, this is what i do :

1. Flash combination firmware and change CSC to KOO with this step :

https://www.youtube.com/watch?v=EyaGf31T6Xc&t=422s

2. then, instead install firmware from that video (R820XXU1ASHF, Tizen 4.0.0.6).

I download and install firmware from this post (BTA1, Tizen 4.0.0.7) :

https://xdaforums.com/showpost.php?p=83403015&postcount=323

3. then, i sideload BP and ECG from these TPK files on attachment

4. then, I let my watch updated to 4.0.0.8 via OTA (R820XXU1BTG1) and install APK SHM v159 from this link :

https://drive.google.com/drive/folders/1u6qpj4Qq4wXDXu6yla50_bji0bAi4naX

Note : i didn't install APK4TPK because when i install APK4TPK, app BCP on my watch would disappear and i should uninstall and install TPK BP again -_-

5. Then setup SHM on my phone, my SHM automatically detect my GWA 2 as supported device.

6. Then after i finish calibrate BP, i try the ECG and BP features and make sure its success.

7. then i let my watch update to Tizen 5.5 via OTA (R820XXU1CTH8) and uninstall SHM v159 that installed before, and then i install SHM v167 from this post :

https://xdaforums.com/showpost.php?p=83480055&postcount=1996

8. Done

i confirm, i have also R820 high battery consumption in 5.5.0 .1 whereas on 4.0.0.7 or 4.0.0.8 i used to get 2 days for sure. No battery saving mode, sometimes 2 days and half.

Hi everybody, I wonder if it's possible to have the ECG and BP installed in a WA2 with CSC DBT?. Or despite installing the TPK they would not work for the CSC?
[Samsung Galaxy Watch] slovenec88:
Thank you for an amazing how-to. Worked for me. Switched from DBT to KOO with oneplus 6T both ecg and bp work great!

Thank you also to all modders here!!

This howto should be pinned.

Anyone manage to get the BP results on Samsung Health app? I get the ECG data syncedto SH but not BP.
[Samsung Galaxy Watch] jdx111:
Same issue here.. But I have my usual S Health, not the Korean. And CSC is OXA in my case.. So not sure how to solve it.

But my BP 1.0.72 and SHM 159 apps are working just fine.

[Samsung Galaxy Watch] lexiperplexi91:
Hi there, this thread kind of moves fast. I have an R820 with the combined BP/ECG app that has worked for the past month. Today, SHM required an update, so I removed SHM and installed from Galaxy Store and it says SHM is not available in my region. Any way to get it back the way it was?
[Samsung Galaxy Watch] mitas35:
On mine i got only ecg ti work which bp.tpk did you install?
[Samsung Galaxy Watch] sahirhussain:
Find the shm mod 5 apk (its here on xda somewhere) and install that.
[Samsung Galaxy Watch] slovenec88:
Hi mitas35, I followed tutorial by the book. I asked OP to add ecg.tpk to the zip as well. He updated it. Just follow the howto, please make sure you removed that retail app from the phone (in case you tried to push both apps via no pc method).

Few days ago my ECG goes crazy...

I am not wearing the Watch... its only just for fun device...

My arm was wet ... sweat and I am short before heart attack... :D

Reason to wear was to demonstrate the ECG function.. but with less time...

Result...

ECG starts without my Finger... stopps after 5 Seconds and ever and ever again... :eek:

Several minutes...

I have tried to capture Screen, because Wave looks crap...

But during measure Screenshot is disabled,,, :mad:

After 10 minutes or more...

I found time to remove watch from my arm... :D

I have cleaned the Back Cover because dirt and sweat... short with my "jeans"...

Then ECG works again normal...

I remember I read something like this in Korean Forum... to clean Back Cover...

Seems too much wet like sweat is also not really good...

Conclusion to me... because I saw dirt on Back Cover...

This is Combination of optical problem... related to Photo Sensor stuff...

Not only the ECG electrical Key...

ECG starts 2 things:

Heartrate with LED Sensors...
[B]AND[/B]
ECG Key

If heart Rate not visible... the bpm thing... then this is step "BEFORE" ECG measure...

Yeah I know you see the Wave Animation...

Limited English skills to describe better...

I found in Ebay Auction Photo...

IMHO visible how much dirt is possible to collect...

Maybe ECG dies earlier if swimming... Running Hard Core workout or only sweating like me... :eek:

Only theory... :o

Hi thanks for the reply ,i tried to uninstall the bp that i thing is preinstall with the koo version but i can't it says error something loll ,i used sdb commands from a post from adfree , igues i made a mistake going csc koo i should try German csc.
[Samsung Galaxy Watch] rasputine:
Hi,

At what version when you did uninstall BP? And what command you used for uninstall BP?
[Samsung Galaxy Watch] mitas35:
4.0.0.8 and i used an old command from a post from adfree,i used that command before with success but not this time it came back with an error
[Samsung Galaxy Watch] rasputine:
I did tried uninstall on 4.0.0.8 KOO and failed too, that's because you're not allowed to uninstall and you're not root...

My suggestion, go back to 4.0.0.7 and make sure your BP installed. You dont have to run it, just make sure it is not disappear on your watch.
[Samsung Galaxy Watch] mitas35:
I change csc 3 times in a month loll

i succesfully record ECG

I just shoved a piece of paper around the sensor protective glass and took out the trash

In the first stage, I managed to access the recording mode for only 5 seconds that was not even possible before, and by further cleaning and rotating the glass with my fingers on watch and adjusting it on the sensors (of course without taking it out), I managed to record for 30 seconds.

[Samsung Galaxy Watch] sahirhussain:
i think its time i start getting greedy about the good folks here to help us get blood oxygen saturation (SPO2) on our GWA2. can this be done? i remember reading somewhere that GW3 too has green sensor light only and it does SPO2.
[Samsung Galaxy Watch] hamid.seyedani:
It may have been forgotten, but according to previous announcements, Samsung uses a blood oxygen sensor to measure stress level right now whether on cell phones with this sensor or on the galaxy watch active & active2

So we can be sure that this sensor is already embedded on the watches!

Another reason is the measurement of blood pressure by the watch because the method of measuring blood pressure is obtained by combining the measurement of heart rate and blood oxygen with special formulas based on my research!

So it is clear that "samsung" will not enable this feature for this time (or maybe never)

(Remember: like activating touch bezel on galaxy watch Active!)

to sell galaxy watch 3 ,because in the galaxy watch active 2 sales advertisements, there was no claim by Samsung to measure the amount of oxygen in the blood, and only the ECG was mentioned that now launched!

From now on, friends who are active in this field may be able to port this feature to galaxy watch/GW active/GW active 2/other models/ by extracting related files and creating a Moded ROM.

I hope and thank them in advance for their efforts

(AGAIN) sorry for bad english!
[Samsung Galaxy Watch] Bi0haZarD:
Your conclusion is correct!! I have observed this behaviour weeks ago, because i also sweat easily...but i thought most people must have thought about the "heart rate sensor" of our watch is indeed optical sensor so it was common sense to me to clean it daily, i spray isopropyl alcohol on microfiber cloth and clean first the optical sensor, then the display, after the straps and last my arm, exactly where the watch "sits" on my wrist. This way, heart rate, BP and ECG always with accurate results. I have dedicated cuff-based BP monitor machine and the readings on both after calibration, are pretty darn accurate ;)

So dear friend adfree, it's not just theory what you have observed, these are indeed the facts!

Well done!! I enjoy people observing small details, they are the ones that make huge difference!!
[Samsung Galaxy Watch] TwistyValhalla:
Need some advice.

I'm using SM-R835F (LTE) in Canada (XAC). It's still on 4.0.0.7. I have installed SHM 1.1.0.167 (mod5) by [MENTION=2998712]caravana[/MENTION] and also APK4TPK for BP and ECG app on my watch. However they're not working on the watch (auto quits) as I believe I have to be on or newer than 4.0.0.8 for them to work.

So at this point what're my options to get the ECG and BP functionality working? Can I change CSC and update to 4.0.0.8 or will that kill my LTE? Or should I keep waiting for OTA for either 4.0.0.8 or 5.5?

Thanks in advance!
[Samsung Galaxy Watch] Huy.tq:
Hi, you can see the guide to change CSC here and will received tizen 4.0.0.8 (currently only available in Korea)

https://xdaforums.com/smartwatch/galaxy-watch/fall-detection-spo2-r825f-ecg-4-0-0-07-t4146551/page2

I am using the R835F version and changed CSC from XXV to LUO (Korea) Group OKA 6 CSC(KTC, KTO, LUC, LUO, SKC, SKO), and LTE is still working fine, only SS Pay is not available.

https://doc.samsungmobile.com/SM-R835F/LUO/doc.html

If the R835F version gets tizen 5.5.0.1, I think Korea will be the first and it likely won't be long.

Hi people.

I'm just curious if I am able to do this on my galaxy watch 46mm EB74 SM-R805F currently on Tizen 4.0.0.7.

I have seen YouTube videos saying it should work on all watches but given that YouTube isn't xda i thought I would check. I searched the thread and it looks like its only for the watch active 2.

Thanks
[Samsung Galaxy Watch] matteo040178:
Your files to change CSC are good also with this region? (I'm also lte sm-r835f)
[Samsung Galaxy Watch] Huy.tq:
I don't know what your watch has CSC but I have done it successfully and fine BP and ECG. Before I changed CSC from XXV my watch only had tizen 4.0.0.7, only BP was active and ECG only ran for 5 seconds to stop.
[Samsung Galaxy Watch] Huy.tq:
For your peace of mind, I have sent more pictures of ECG activity, tizen version and LTE wave
[Samsung Galaxy Watch] TwistyValhalla:
Thanks for your detailed instructions!

After updating to 4.0.0.8 can I change my CSC back to XAC to use Samsung Pay? Also will I receive OTA updates in the future?
[Samsung Galaxy Watch] Huy.tq:
if you want to go back to XAC then you need to have stock firmware for Canada to come back and you can also get the latest OTA in the near future for your region with such sequence (which is in theory) because I haven't done this yet and because my region doesn't have the 4.0.0.8 update, but at the moment you return to XAC, you will also have tizen 4.0.0.7 (because the tizen version is updated by region You need to change to Korea)
[Samsung Galaxy Watch] matteo040178:
Yes I trust that everything is working fine for you (except Samsung Pay), my only doubt is to mess things up with wrong files for my CSC

[Samsung Galaxy Watch] radiotech:
First of all I would like to thank everyone for their hard work on getting the BP and ECG to work on the Active2. I have just finished reading through all 213 pages of information. I originally had a 825U LTE watch, but when I learned that this requires Tizen 4.0.0.8 I returned it to the store and got a Active2 model SM-R820NZKAXAR. Out of the box it was running Tizen 4.0.0.7. After I paired it to my phone I checked for a software update and 4.0.0.8 download and was installed. The software now shows as R820XXU1BYG1 SM-R820NKAXAZ. My CSC is currently R820OXA1BTG1

To get everything to work do I just need I install Version 165 from [MENTION=1030585]adfree[/MENTION] and modded by [MENTION=2998712]caravana[/MENTION] and the orginal BP.TPK in post #208. Or do I need to install different versions? Thanks for any help.

Mine works just fine, but realised that it is important that the strap is enough tight. Just made some trials with loose strap, and the results were same as yours. Than made it one hole tighter than how I usually wear the watch, and results were again good. This applies for blood pressure also
[Samsung Galaxy Watch] Gary02468:
No, it works fine with a low heart rate. It's just that the algorithm will classify it as Inconclusive rather than Sinus Rhythm (that's documented in the instructions).

hi everyone,

after week of battle with rooting and changing csc it finally works!

My solution for R820 is to :

1) Change csc to DBT (German)

2) Update firmware to version BTF (excatly this version) version bta on 4.0.07 works only 5 sec ecg and wont update by OTA (error on update), versions after i cannot install ecg and bp becouse its already preinstaled

3)Install BP.tpk and ecg.tpk

4)install samsung healt monitor by caravana 167

my problem was that phone wont update by OTA when i install 4.0.0.7

One question.

From what I understand, then in a BTG1 firmware, installed by Odin, the tpks cannot be installed ??

I was thinking of going from BTF3 to BTG1 via odin, to see if the ECG would work better.

BTG1 is the latest firmware avalaible (no ota) ?

You have to VPN to Korea to update ECG on galaxy store and install SHM mod 159 or 167 of caravana on your phone. Note you have to remove sim on your phone and delete data and cach on galaxy store to update ECG. After update ECG is it active. (I did it many times for success)

If not success, you can install ECG.tpk to use https://drive.google.com/file/d/1-JCh10rQC0Qmbbc3SD0TezPz7cgtttXz/view?usp=drivesdk

[Samsung Galaxy Watch] Huy.tq:
In tizen 4.0.0.8 BP upgrade package BP and ECG are installed automatically so BP file becomes default and you cannot delete it, I did it by various methods but it couldn't be deleted. So you can only install ECG with the ECG.tpk file. But the BP on my watch still works fine even though I can't delete it

I unfortunately didn't find a solution for this. The problem actually worsened. Now, when I put my finger on the back button, nothing will happen ?
