openwrt on tp-link wdr4300

the openwrt was installed and configured as routed client relayed, and I need to reset the openwrt to factory default to use it as a WAP, here are the steps

1. Power the router up;
2. After powering up track the SYS light when it starts to blink, when it does press and hold the WPS/reset button till SYS lights starts to blink faster – router goes to recovery mode;
3. Telnet to the router on 192.168.1.1 – no password needed (if your computer doesn’t gets IP address from DHCP assign it manually for i.e. 192.168.1.200 with netmask of 255.255.255.0);
4. In telnet terminal type `mtd -r erase rootfs_data` to reset OpenWRT to it’s defaults. then the router will reboot.
5. after reboot, telnet in and passwd to set a password.
6. use PUTTY to ssh to 192.168.1.1 with username root and the password.
