SOS: need firmware of BSNL ADSL MODEM - SL2-141

Hi

My friend have a Nokia Siemens SL2_141 Wifi ADSL Modem.

He forgot his Modem (not DataOne) password, he changed it himself, so I press the hardware RESET button.

But, I think, it also erases the firmware also.

Now when login to http://192.168.1.1 it says -

Can someone pls give me the default firmware which I can burn it and save it.

Thank you in advance.

Anyone ?? My friend needs it as he has to reset the modem. I called the tollfree number and they never heard the word “firmware”. lolz

Besides, any way to backup the current firmware ?? It’d be very helpful if someone posted a guide/tutorial about flashing SL2 141 modem. :frowning:

NOt sure if this is correct thing : click on firmware

^ I will reply u tomorrow with details.
