I've been trying to figure out how to reset the WNDR3800 running OpenWrt trunk version. I've tried holding the reset for 30 seconds on startup, for 60 seconds on startup, the 30-30-30 method, the NetGear method (after booted up, hold for 2 seconds). Nothing seems to reset the password for the root user back to blank so telnet works again. Am I just doing something wrong (likely :-), or is this a defect I should report?
I need to get back to telnet, as I had the router user/password set to root/root, but after reloading the firmware with sysupgrade, and not putting anything in the /etc/sysupgrade.conf (I didn't feel I needed to save any settings), the root password no longer works to get in with an SSH connection. It responds with "Access denied".
Thanks for your suggestions!
