Hi Voxel,
I read on one of your previous threads that you recommended to erase the overlay_volume partition to avoid possible conflicts with other firmware using this sequence:
1) enable telnet:
http://191.168.1.1/debug.htm
2) telnet to your router IP
3) format overlay partition running the command from telnet:
mtd erase overlay_volume
4) hard reset
When I do this I receive the following error code:
Could not open mtd device: overlay_volume
Here is a copy and paste from my telnet session

telnet password:*******
=== IMPORTANT ============================
Use 'passwd' to set your login password
this will disable telnet and enable SSH

Any ideas why this does not work?
