Hello I have got problem with my WRV200 after I tried to upgrade firmware. Previously I got 1.0.21-ETSI and I tried to upgrade it to 10.0.34. I did this by webUI: selected proper file, confirmed and waited about 10min. I saw all the time only white screen in my web browser. Router was going properly during this. After those 10min I tried to log into WebUI in other browser, but WebUI was not reachable. I tried to hard reset it or upload firmware by tftp(tftp not responding), but nothing helped. Now I can't reach WebUI and also router not work(its not reachable from lan). Only LEDs(power,internet,port1) lights. Do someone have some idea or solution of this problem? Maybe resetting flash can help, but I did not find any documents about how to do that. I bought my WRV200 two months ago, so is it possible to repair that in authorized service without paying for that?
