Getting to uboot / recovery flash mode:
0) unplug your router
1) Press in and hold your reset button and do NOT release
2) While holding the reset button, plug the power back into your router 
and continue to hold the reset button
3) The status light will come on and hold and eventually it will start 
blinking ever 1/2 - 1 second. Once it starts to repeatedly flash, 
release the reset button and connect an ethernet cord to your PC (if you 
haven't already).
4) Go into your PC's network settings and assign yourself the private IP 
of 192.168.0.2
5) The router is now in recover mode and is listening to HTTP request on 
192.168.0.1
6) Open up Internet explorer (or Firefox, just make sure you clear your 
caches in both) and navigate to 192.168.0.1
7) You are now in the recovery flash GUI

P.S.: Jei trumpai, jungiam routeri i rozete laikidami reset mygtuka. 
Kazkiek sekundziu laukiam, kol neprades kitaip mirgset. Su salyga kad 
kompiuteryje nustatytas 192.168.0.2 ar koks nors kitas is sio potinklio 
tik ne 0.1 bandam su internetine narsykle atidaryti http://192.168.0.1 - 
turim pamatyti Recovery Mode puslapi, per ji ir kraunam originalu firmware.
