Hi,

After a power surge my router fails to boot with below error.

I already tried with a couple of images. Including a back up of image that
was running(c7600s72033-advipservicesk9-mz.151-2.S.bin) and an older
ones(c7600s72033-advipservices-mz.122-33.SRD4.bin  and
c7600s72033-advipservicesk9-mz.122-33.SRE5.bin).

Anyone ever had this issue?

If I boot to ROMMON and check the boot device the image is recognised.
Any help/advise will be appreciated.

Regards,
