[MENTION=1030585]adfree[/MENTION] ah, mine fails when I try sdb root on

>sdb root on

* The version of SDB client (2.3.0) is not same with that of SDB server (4.2.12).

It may cause version compatibility problems.

It is recommended to use SDB server with version 2.3.0. *

Any idea how to get around that?

You need Root aka Super User aka su Binary inside Firmware... this is Linux stuff...

[MENTION=11155683]betterl8thannvr[/MENTION]

You are in similar situation like me...

No latest files leaked...

ATF2 is latest leaked Files for netOdin...

So much harder to get Root Access... :o

I have at the moment limited time to explain nor to make the files for you...

Maybe next days more time...

What happened after reboot ? :)
[Samsung Galaxy Watch 3] :
thanks [MENTION=1030585]adfree[/MENTION], I think I can figure out how to root on ATF2, but you said you had root on 5.5, so I am quite curious about how to do that without the leaked files. :)

I will keep poking at it.

Hmm, well, flashing back to ATF2 is being troublesome. It fails every time, so I now have a small, expensive brick.

@adfree I came here after following Dante63's ECG/BP thread. I have a GWA2 and I'm trying to run SpO2. After signing, installing firstBlood_oldest_v19_pubPriv_v1.tpk, giving permissions and launching it, I have ran into the same problem as Vuska and 73sydney, i.e., it get's stuck at around 80%. Any ideas?
[Samsung Galaxy Watch 3] adfree:
This is known since monthS.. because we have NO final solution.

IMHO I have several examples uploaded...

Difference between old way and TPK only... is...

You need no ROOT on watch...

AND you not need to make pain in a. to uninstall SH... because SPO2 is inside Samsung Health...

IMHO I have simplified the old way... in hope more then 1 user could contribute...

Research... Reverse Enginer... do some brain activity... to find final solution.

Still none help from GW3 user...

HI to all,

Just bought the GW3 (SM-R840 / R840XXU1BUD1 / SM-R840NZKALUX) to use with my Galaxy S20 Ultra (SM-G988B/DS - SAOMC_SM-G988B_OXM_LUX_RR_0010) and I was shocked when I found that I can't use the ECG and BP because it seems the Samsung Health Monitor is available for the whole EU except for Luxembourg (one of the founders of the EU community). On top of this, I can't find the SpO2 on the watch.....not my greatest day.....

So, I was searching for a way to force it to work and I found this post.

I read several pages (not yet all of them) and found some useful youtube links; however, since they are dated back to 2020 I was wondering whether they are still valid or if there is a newer procedure to change the location to my GW3.

Do I have to do the same for my S20 as well?

I have also noticed I'm missing the Samsung Pay app.....

I will be more than happy if I can help you back (but you should tell me what to do and maybe how :-P )

Cheers
[Samsung Galaxy Watch 3] Vuska:
Yes, still same... and as i know, page 1 already updated.

And... great... as you have GW3, maybe you can provide some help to sir Adfree for SpO2 too...

I will send you a private message.

EDIT: I sent you a message, but I'm not sure I can send you a "private mail" since I'm a new member

EDIT2: In the meantime, I have found the BO as widget (as reported by adfree in the first page). It works, but I'm still not able to use the ECG/BP. Not sure whether the issue is with the watch or the phone (or both)
[Samsung Galaxy Watch 3] adfree:
Still with my skills and tricks nothing new...

I am still waiting for help from GW3 user(((s)))... :devilish:

In Ebay I saw some offer for defect GW3... but no idea what is damaged... because 100 Euro is not really cheap for dead device...

Still reason for GW3 feedback is... to identify where the f$%ing Trigger is... inside SH TPK or inside Firmware/Kernel?

Still in all SH and also inside these SH Sensor ext crap is:

libspo2.so

With text strings:

Why is this inside?

SM-R820 SM-R825 SM-R830 SM-R835 Renaissance

Why?

Is this Library involved or fake dummy or?

IMHO answer can come easier from tests with GW3...

But I would be up to do the necessary testing for you @adfree
[Samsung Galaxy Watch 3] jadonv:
Hi @adfree I finally had a chance to try this out. I managed to get the tpk signed and installed through the Tizen studio!

It shows up on the watch, opens, scans, and then... no joy.

It keeps getting stuck at 80%..

Is it possibly because my SHM app on the phone is the wrong version?

I don't see sp02 when opening it. Only water which is manual.

Lazer is also a reddish green color.

Let me know if you need anything else. Appreciate the hard work on this!
[Samsung Galaxy Watch 3] jadonv:
After opening the SH again it does now show the blood oxygen card!

Still won't complete cycle on the watch though 😔

Edit:

SH on watch does not have blood oxygen showing up. I'll try find an updated TPK to see if it completes.

Standby...

Edit:

Tried installing the modded Samsung health from dante63

Samsung Health 6.16.0.047 (minSDK26).apk

but still cant get the TPK on watch to show blood oxygen..

@adfree do you know how i can get it to update? Could it be tied to region on the watch? im currently under: XAC

SH on watch is currently on version:

4.16.102000
[Samsung Galaxy Watch 3] adfree:
@jadonv​

Thank you very much for testing and posting test results.

I have removed few Binaries from TPK so it is normal it stuck at 80 % and not finish...

This is confirmed by other Galaxy Watch 3 user.

Stupid question because maybe missing in Translation or simple not read fully from me...

Ehm....

Blood Oxygen normally work on your Watch? Or Country Restriction?

@adfree nope it normally wouldn't work. I'm in canada under XAC region.

Sorry, my tests with rooted devices and never really focus on Country check...

So for your not rooted device is hard to replace Original SH on Watch...

But maybe this Samsung test can be used parallel to Original SH...

Thanx for testing.

Maybe no signing required.. because Original Samsung Signature...

@LollosoSi it's been a while since I been on hear but I am ready to try this for you where can I get the .tpk file from cam you convert it to .apk and will down load it on my phone and install it which will transfer it to my watch. Waiting for your respond.
[Samsung Galaxy Watch 3] LollosoSi:
Thought for the users who could manage to start oxygen measure with flat graph, that command would help get some output through the graph.

I couldn't try it myself but I could see instead that this command stops the current HR/stress measure (shuts led and measure fails). Letting the red led shut itself and reissuing the command continuosly actually gave some graph output. Not sure if this observation could be useful in some way
