Mam ho sice doma, ale netusim jak to je. Kazdopadne jsem nasel tohle:

I found a solution on this site and others.

On this site : http://wiki.openwrt.org/toh/tp-link/tl-wr1043nd#se rial

Failsafe mode

Power up your router. When the 'SYS' light starts to blink, press and hold the 'QSS' button in the front-right until the blinking gets faster. Now open a telnet session to 192.168.1.1. No user name or password required.

From there you can mount rootfs_data user space to fix things or just erase it using

mtd -r erase rootfs_data

I have done that and my tp-link works now !

The sys led is now flashing and I can login.

So after this very bad trip, I upgraded the genuine firmware. Don't talk me about the openwrt....
