[Q] RockMyMoto: CydiaImpactor fails + screenshot topic

So, I'm having Droid MAXX ver. 12.15.15 and can't get root through Cydia Impactor.
USB Debugging is enabled, there is no screen lock, but every time time I try to start telnet daemon through Impactor

# start telnetd as system on port 2222

There is an error in attachment


Regular usb debugging through eclipse works fine.

Has anyone solved this problem?
