Hi

Looks like image might be corrupted corrupted SHA-1 hash doesn't match , is there only one image in flash ?

You could add another one if only 1 then try boot or try boot an image from usb instead , then when its up transfer between usb and flash

rommon 1 > boot usb1:isr4400-universalk9.03.15.01.S.155-2.S1-std.SPA.bin

Thanks for quick reply, I have tried another IOS but the same problem and I have tried to install from USB but Unit is not picking USB it is showing nothing, anyother help please?

so if its not seeing usb then its the wrong format in usb , reformat to FAT then add your image and reinsert then boot

Please post full outout from console if it fails to boot when usb is reformatted

apart form usb you now have 2 images in bootflash yes ? Have you validated the md5 of the images there ok and match what you downloaded ?
