I have two dsl 2750u one is at my home and another one in my shop, i took backup file of one router (config.img) and tried to restore on 2nd router, after that my dsl 2750u got bricked.
no ethernet connection no wifi signal only leds are flashing, i tried different reset methods found on internet but no luck.
Finally i decided to fix it by USB TO TTL method and i connected router to pc by serial and setup everything , and opened putty,
It showed something like this

Code: [Select]

press 'esc' to enter boot console
 ext phy is not found
Copyright Realtek inc When i pressed ESC key it showed like
<rtl867x>
So i tried entering "e nvram" , "erase nvram" , "nvram erase" but nothing happens.
I'm sure that when entering "reboot" and enter the router reboots
Please help me to erase nvram and fix the firmware

Not sure if this will help any:
Emergency Recovery Mode

If not, I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
Let us know how it goes please.
