Can you connect your phone through adb logcat and share the error code?
had not yet attempted to do this, I tried now, but I do not realize what to do 
What didn’t you understand exactly? Can you be more specific?
I can not do the steps that are in the tutorial 
Have you tried these steps? -> https://docs.coronalabs.com/guide/basics/debugging/index.html#device-debugging-android
Yes, but when I write these command in CMD says that is not part of the internal controls system
You need to <cd> to the directory where adb is installed and then write the adb logcat command.
