Still open:
"arm -i 9052" - is asking for a Controller password while I have a HashedControlPassword in place ?
if you configure tor to require a password for controlport access (that what HashedControlPassword is for), you will be asked for a password (expected behavior).
https://www.torproject.org/docs/tor-manual.html.en :
HashedControlPassword hashed_password
Allow connections on the control port if they present the password whose one-way hash is hashed_password. You can compute the hash of a password by running "tor --hash-password password". You can provide several acceptable passwords by using more than one HashedControlPassword line.
