Default Dlink Modems Firmware Dump Promblem

Hi there

I have 6 D-link modem in three different model 2700u,27430u and 2460u


The problem is in each couple of those I have one working and one dead modem
I read working modem bios/firmware and use this dump file to write on dead one's bios, but no chance and modem not even power up.

when I change just EEPROM IC of 2 working D-Link modem but use original data they wont turn on but with their original hardware and DATA file they're i think there must be something that I not aware of something like saved IC identity somewhere

but in other hardware like tp-link modem it's not an issue
and i can use different EEPROM ic or different dumped file without any problem
so what's the problem with D-Link modems?

another question: how should I read data with JTAG pins?

If you guys need any data , Bin file or dump Data or any image please let me know.

fist you need to bring the firmware back to what it was. Use a TTL to hook up to those pins. Try to clear the nvram and see what that gives.
