The sideload on my Moto 360 1. gen stops at the last step,-
look at the screenshot!
I guess, I made a mistake by writing the last line!?!
Maybe the path to the APK is not right?
I stored the APK`s in C.\adb
I was following this instruction on XDA: adb -s localhost: 4444 installiere -r pachagename.apk
Any APK not from the original developer is a fake and probably contains a virus. Sideloading will not solve your problem, use the developer’s recommended installation instructions.
