ZTE ZXDSL 831AII modem / router firmware upgrade

Warning: All Local PPPOE Settings changes to default value after upgrading, You have to reconfigure your broadband "username" and "password" and other pppoe settings after upgrade.

Here is the link for ZTE ZXDSL 831 AII firmware upgrade provided by BSNL :

I did not noticed any major change in functioning of modem / router, only some graphical interface and viewing changes. Some menu and configuration settings changed now & can be easily accessed. After upgrade you will find all settings and configurations by typing hence dose not required any more as earlier.

I even tried it on Nokia Siemens Networks's C2110. Firmware of Nokia Siemens C2110 now changed and it is showing ZXDSL 831AII as modem. Though firmware worked on C2110 and my modem is working fine, it is not advisable to do upgrade on nokia siemens C2110 at all.
