my device is dsl2520u adsl router...
i upgraded original firmware with wrong firmware, after that, all lights on modem is off when i turn on the modem, even the "power led", but if i connect modem to pc using lan port, the lan led will be lighted up, that shows the modem has electricity, this will be occurred if i connect modem to pc using usb port, but other lights (power, status, dsl and internet) are still off...
i read forum before, and i know, i can turn modem off and hold reset button for several seconds and turn modem on while the reset button is still holding, and reach the modem by web ui using 192.168.1.1 to emergency flashing, but in this case (when the power led is off) i can`t do that, and i can`t see web ui to emergency flashing, also i have no ping 192.168.1.1
my pc has static ip = 192.168.1.2 , and my modem is 192.168.1.1
my modem is completely dead, do i need to some thing like hardware reset ? or anything like that, to backing to original firmware ? or ...
i need a way to turn on the power led, after that at least i can use emergency flashing...
thank you
