Yes! So sorry i didn't understand if BP don't work, have to go to the alternative way...I'm gonna take a guess that the error said couldn't install and then the tpk installer was asked to be uninstalled...
I think the tpk you're trying to install is unsigned, because of the one of the 3 reasons:
- The certificate doesn't have the watch DUID
- Running sign.bat has errors
- You took the tpk from sign_me instead of install_me after running sign.bat successfully
I was trying to install the Samsung tpk installer on my phone. Perfect exemple for guys like me who didn't watch your videos carefully...
Now I did all by the alternative way and succeded to install BP and ECG on my watch!
The only thing to mention is that i had to instal JDK 15 instead of 16 to make succesfull signing in FIT2INSTALL app.
Thanks again for your work!
