After upgrading software & bootloader the box get stuck and it is not possible to upgrade it any more. It seems that the bootloader is corrupt! I have used the same USB memory as I always been using for the upgrades. I have tried with an other USB memory + tried formatting and tried using the HP-tools as well with no sucess. It is possible to access the box by telnet and ftp but not the web interface. How can I do to get the box up an running again?
