There is an entire section for downloads, what problems are you facing so I could assist?
Do a clean Odin flash install of the ROM, what I usually do is through custom recovery I delete and format my phone then I go into download mode and flash the stock ROM, preferably old ROM, after that, I let the phone update to the latest ROM, this process ensures that from a flash to update, your files are back to its original state, you can check build.prop by adb command if I'm not mistaken, pull and read, I believe your build.prop tima is still 1

Tienes FRP Google Lock en tu teléfono
El centro de servicio de Samsung puede quitarlo fácilmente pero por una tarifa, pero si lo quita usted mismo, buena suerte, existe un alto riesgo de dañar el teléfono.
Samsung health app is only for BP sync and nothing more...
Since you have ECG, that means you have SHM and which means you already have BP on the watch but disabled with high version so you can't install BP to enable it, your option is signing the modified BP and installing it like everyone else...
Because you installed BP.tpk and not modified_BP.tpk, BP.tpk doesn't need to be signed, it has Samsung signature, you install it, if it fails, you check the watch, you see SHM, you realize this means package BP.tpk is already on the watch but disabled, so you go for the alternative method, installing the modified version, boom, installed...
