Load firmware from Failsafe UI
1. disconnect power
2. on PC set address 192.168.0.2 netmask 255.255.255.0
3. push button reset and connect power
4. after 6 seconds release reset button and open in browser http://192.168.0.1
5. browse *.bin file and upload firmware

You should downgrade bootloader, adn then flash openwrt using failsafe ui. To do this you should download old version of uboot http://yadi.sk/d/dJzulSpxGcG2i, then run tftp-server on your pc and put file.bin into server directory, then telnet to the router and run tftp -g -r uboot.bin -l /var/tmp/uboot.bin ip_of_your_pc, then dd if=/var/tmp/uboot.bin of=/dev/mtdblock0 bs=64k count=3. Now you can flash openwrt via failsafe ui into b5 b6 or b7 because they have same hardware. Good luck!

Hi.

I've got DIR-300 NRU B5.

NRU B5 and NRU B6 are identical (as firmware the same: B5, B6). Platform is RT5350F. So, openwrt for B7 version is a good candidate for test.

In brief, it works. I tested with BB and CC uploaded over rescue mode web interface )after flashing latest available official firmware).

Besides forum only this page - http://wiki.openwrt.org/toh/d-link/dir-300revb5

But no information in TOH. Can someone update TOH - add NRU B5, NRU B6, NRU B7 to supported hardware.

The discussion might have continued from here.
