Dear all,
I’m the owner of a rb433AH and I’ve tried to update it via the net install tool. During the installation I pressed the cancel button and since then the rb only POST and it doesn’t boot-up , I think I’ve must have deleted the nand 
. Is there a way to fix this problem ???
Sorry for my bad English an thank you in advance !!!
What does the router say via serial cable?
Problem fixed. With the serial cable I’ve seen that the system was halted. I’ve formated the nand and enabled the boot from Ethernet option and finally with the netinstall tool I 've uploaded and installed the packages again !!!
case closed topic closed thank you all
