how can i dump a generic device bios/firmware?
hello all , im trying to dump my adsl modem firmware , but i dont know how ,
i have seen tools which were made to dump playstation bios to computer, but i couldnt find any articles which would describe the procedures and howtos .
the story is i tried to upgrade the modem with the latest firmware from my isp , and it happened to mess my modem functionality , so i thought it would be a good idea to actually reverse the procedure happened meaning to dump another intact modem firmware and upgrade mine with that .
anyways, any thought on this issue is appreciated . anything form needed knowledge base requirements(knowledge concerning the device!, coding, etc),how to approach it and stuff like these.
thanks alot in advance
