SOLVED Can't enter configuration

Installing and Using OpenWrt
1

Hi, my router is Linksys wrt1900acs v1, just root LEDE firmware. The root was successful. And I can access configuration right after that.

When I tried to enter my account and password for internet, I chose LAN instead of WAN by mistake. And after I confirmed the setting, the router rebooted automatically.

After that I can't never enter the configuration.

Can anyone advise how should I do to restore it. Thanks!

Use failsafe. https://wiki.openwrt.org/doc/howto/generic.failsafe

Thanks. It's too complicated. Can I restore to Linksys original firmware? This might be easier.

I restored the router to its status before rooting by "on/off x 3" method. Quick and easy.
