Stuck in Rommon mode!

Hey guys so after trying everything I know, I'm coming here to get some help

I have a 1921 router and it was working just fine, by mistake I formatted the USBFLASH0: (I thought it was the usb driver that I inserted) but not it was the actual flash of the router

so now I'm stuck in rommon mode and I have a good image but no solution yet, I try to boot from USBFLASH1: and I got this message

rommon 12 > dir usbflash1:

program load complete, entry point: 0x80903000, size: 0x4c4a0

Directory of usbflash1:

rommon 13 > boot c1900-universalk9-mz.SPA.152-4.M5.bin

program load complete, entry point: 0x80903000, size: 0x4c4a0

an alternate boot helper program is not specified

(monitor variable "BOOTLDR" is not set)

and unable to determine first file in bootflash

loadprog: error - on file open

boot: cannot load "c1900-universalk9-mz.SPA.152-4.M5.bin"

any help would be more than welcome
