Ok, let us know if you can get it working. Ya seems like NVRAM is hosed. You might check the WRT forums, I believe I saw someone over there that had a similar issue on either a 868L or 880L a while back.
I wish D-Link offered after warranty repair services for some of there routers. ![Roll Eyes ::)](http://forums.dlink.com/Smileys/default/rolleyes.gif)
Bought a serial adapter and got into the CFE command window. The router is reporting error : “Invalid boot block on the disk”. Tried “nvram erase && reboot” didn’t help. Also tried using tftp flash officials firmware and dd-wrt firmware. Officials firmware give same “invalid boot block” error after reboot, dd-wrt firmware will hang after reboot. What in notice is this router has 4 different set of flashes: flash0.*, flash1.*, nflash0.*, nflash1.*

The tftp flash method I have tried are: (my tftpd runs on 192.168.0.2, 115-firm.bin is the file name of the firmware I used for flashing)
flash -noheader 192.168.0.2:115-firm.bin flash0.trx
flash -noheader 192.168.0.2:115-firm.bin flash1.trx
flash -noheader 192.168.0.2:115-firm.bin nflash0.trx
flash -noheader 192.168.0.2:115-firm.bin nflash1.trx
They all reported programming completed successfully with status 0.
But after reboot, the router still complains “invalid boot block”.
Hope someone have more experience with JTAG can help provide some suggestions.
Thanks
