Hi all. Its happened on my RB2011UAS-2HnD-IN. After some experiment i was connect to router and set /system reset-configuration. After that i saw Loading kernel on LCD and it message go on.Then i connect serial cable and saw Kernel panik message. After some browsing google i decided to reset nand flash memory and upload new kernel. Install TeraTerm and upload ar9344-3.04.fwf (file-tranfer-xmodem-send).so after reboot i see RouterBOOT backup booter 3.0 and after that still get error :
Press any key within 2 seconds to enter setup..
loading kernel from nand... kernel not found
trying bootp protocol................................. failed
kernel loading failed
Netinstall cant see any devices… Help! THX!!
