Hi there,
I'm from Serbia, so excuse my English <_< and this is my first post on your forum....
Here is the thing... Serbian Telekom (largest ISP in Serbia) is giwing Huawei ADSL routers to their users. The routers are locked, and you can get only user level username and password(which are username: telekom password: telekom). With usel level access you can see only some statistics and can't modify anything (eg. port forwarding), so a lot of people have trouble with P2P access etc. Reseting the device does not help, but there is trick :)
Here is the hack:
* Enter: telnet 192.168.1.1
* then enter username: telekom
* and then a password: telekom
* when you log in enter: passwd admin admin
* then enter: save
* then enter: reboot
* wait a minute for device reboot
* and now you can log in via http admin access username admin / password admin.
So, if you have locked huawei adsl router and you have only user access level, telnet, log in with user level access account and change admin password to whatever you like ;)
