If you still have the certificates or the signed shm mod, you might not need anything, try to install it on your watch, there is a chance the watch DUID is still the same...
The watch DUID seems have changed, this happens after several resets,I'm not 100% how and what triggers the watch DUID change...Hi, I have a problem that I do not understand, I have always used your mod and the 2 apk (1 for ecg and 1 for pressure) certified by me with your method with success, every time I changed phone or rom I just needed to install the files again to get all working. Now when I install the ecg and BP tells me failed to install, I have several copies of the files all do not work I tried to recertify with no result. Tips?
You'll have to create new certificates and sign a new copy of the mod
