this is my first experience with rommon, for fix rommon on router /3600/3700/3800 series please follow step bellows
First issue the dev command in order to see which devices are available on your router:
rommon 1 >dev
Devices in device table:
idname
flash:flash
slot0:PCMCIA slot 0
slot1:PCMCIA slot 1eprom:EPROM
rommon 2 >
Next, issue the dir [device ID] command for each Flash or PCMCIA device available, and then look for a
valid Cisco IOS® software image:
rommon 3 >dir flash:
File size Checksum File name
35823432 bytes (0x804b4c) 0x6ba0 c3845−adventerprisek9−mz.124−10.bin
rommon 4 >
Try to boot from that image. If the file is valid, this brings you back to normal operation mode:
rommon 5 >boot flash:c3845−adventerprisek9−mz.124−10.bin
program load complete, entry point: 0×80008000, size: 0x804a30
