DSL-2730U CFE boot problem

Hardware Questions and Recommendations

Hello there

I have a D-Link DSL-2730U HW: C1 that didn't turn on after an electricity outage. I opened it up and try to write a new dump hex bin file on it. I first used "e n" and "e a" commands. after rebooting I tried to update the modem by uploading an image file in the web interface in 192.168.1.1.
After finishing writing on the flash, all lights were turned off. after a while I turned the modem off and on. but nothing happened! I just got this on the serial terminal:

I think I caused the bootload to be damaged but I don't know why or how!!!
What's happened exactly? Do I have any way to fix that by myself?
this is my serial log after doing 'e n':

You should probably ask D-link, not us.
