This fix is for those who have a Conceptronic CHD3NET (or any device running RDC’s 2891 LANDISK chipset) and upgraded it to a new firmware but where it did not reboot properly: here’s the tip how-to restore the firmware especially when your firmware upgrade failed and you are only able to ping to the NAS.

Other features seem unusable to start: the web user interface at 169.254.0.1  cannot start and TFTP functions are also not functioning (RDC does not support Telnet) so it seems you are now the ‘proud’ owner of an USB storage device!

Here’s are the steps how you can try to fix your bricked LANDISK with RDC 2891 chipset:

1) Download the latest firmware
2) Download this file
3) unzip this file somewhere on you harddrive and browse to the ‘Utility Tool’  Directory. Execute Scan ip.exe and perform a scan, after a moment your NAS will be found by the program.

4) Select the NAS from the list and press the SETUP NAS button, you might get some error message but just ignore them. Now you’ll entered a menu where you’ll be able to download new firmware to the NAS.

5) Browse to the directory where you saved the .bin firmware and upload this to you NAS, afterwards you’ll need to reboot and back is you WebInterface
