EX6200 Frozen

Was doing a firmware upgrade and the session timed out, could not connect to the extender again, have the 2 top lights solid yellow and the Device to Extender light flashing green, it won't boot up evern after a power reset.  Tried the reset button with no luck.  Unit is a year old so it is out of warranty and I refuse to pay Netgear to troubleshoot their garbage for the same cost it would be to buy a new one,which I won't, have had nothing but problems with this piece of crap from the beginning, they even say if the firmware upgrade is interrupted it can cause the extender to be useless, who develops a product like that?  Will be switching to Linksys or DLink, both linksys and Dlink warranties their products for one year unlike netgears 90 day.
