4451ISR./9K upgrade failed. it at first refused to recognize the flash:(or bootflash:) but it let me load from the usb1: so I transferred the image from usb to flash and as well as rommon package to upgrade. it required to restart for order to upgrade. now it is stuck in the state below:
Initializing hardware ...
ERROR: C90000002:V305100D I C9DCF469-A7C4-11D5-87DA-00062945C3B9 BE004000 ERROR_UNRECOVERED:SOFTWARE_DXE_BS_DRIVER:ERROR_UNRECOGNIZED:0
I cannot get out of it or roll it back. what is the solution for this?
ROMMON: isr4400_rommon_1612_2r_SPA.pkg
