Kernel issue

Dear all

I have a router 450G.Previously I had some issues with kernel but sorted out.This time when I try to configure the router and after a reboot, the router is not booting at all.Again showing the same error ‘kernel not found’. Again I uploaded the firmware and I done the previous processes,again getting the same error as ‘kernel not found’. Please help me to sort this issue.

Which RouterOS version is installed on RB450G?
Please write what exact actions you were performing before getting this error.

The router version installed on RB450G is 5.23.

After upgradation of the firmware, I configured the router means I changed the IP address of ether1 and ether2 and made a reboot.After that the router is not booting at all.Then I connected the router through a serial cable,and the router is showing the error as:
RouterBoard 450G

CPU frequency: 680 MHz
Memory size: 256 MB

Press any key within 2 seconds to enter setup..
kernel not found

Then I again upgraded the firmware and done the same procedures as above. After that again it is showing the same error:kernel not found.
