Is there a way to root without using the telnet? I would turn off AP isolation, but the router is my roommate's and she doesn't know the login info (not the same as the default log in on the bottom of the router).

GG on my part.

Buy or borrow cheap used router (like an old Linksys wrt one)

Power it on (does not have to be connected to the internet) and make sure it's on a different subnet than the real router you use so it doesn't interfere (i.e. switch it to 192.168.2.1 if your normal router is on 192.168.1.0/8)

Connect your phone to it

Connect your pc to it

Use telnet as stated in the OP

Either that or reset your current router back to factory defaults and regain the login password.
