Specs: Windows 7 64bit, i3 2.33/4gb ddr3
i have Aztech DSL605EW wireless modem. I updated its firmware on some philipines Globle Broadband network's firmware. Now the problem is to open its configration I have to use IP and the configuration settings are very limited and there is no option of updating firmware in it.

I am stuck with it. Please tell me what to do :(

Buy a new one. Probably cheapest, fastest, and easiest way.

To fix the one you have, you'll have to replace the PROM chip with a preprogrammed one, or remove and reprogram it with an EEPROM burner.
Take it apart and get the Chip number from the PROM. Get the spec sheets for the PROM and maybe there is a test circuit listed that you can build to "test program" it with.
Maybe someone knows how they do it at the factory.

I've seen it happen on mainboards too. Updating the BIOS can make them useless.
