I have the mf612 3g modem (http://wwwen.zte.com.cn/en/products/mobile/handset_services/faq/201007/t20100705_187032.html ) .The nmap output give me that is running on linux.I can connect to the telnet ,but cannot log in.I try the root and my admin pass(pass is admin ( default pass) ) no success.
But when i type admin admin the telnet session dont give me anything(not shell, no error)
Questions:
1) How i can loggin' to it?
2) Is it possible to install to this device another Linux distro?(I need this to install additional soft - vpnc )
3) Where i can find the service software to connect router via miniusb?
4) Is there the jtag or serial port(see the photos)?
