Solved: Re: 3945 Router booting to ROMMON

SCOTTA63123 · ‎01-22-2019

A 3945 came to me that was returned from the field and I was instructed to clean it up (physically), wipe the config and upgrade the ios.

Where I made the mistake was I copied c3900e-universalk9-mz.SPA.152-1.T.bin to the flash and deleted the original ios thinking the new ios was just going to work. Now upon boot, I get the rommon> prompt and I can't seem to work my way out of it. (I've tried varios ios versions via the 'boot usbflash0:xxxx' process without succuss. There is more detail I can give concerning what I have tried but I don't want to muddy the waters right off the bat with too much noise.

Has anybody worked their way out of this and can help?

I think you just typod the path. get into rommon and try run "dev" that should give you the storage devices you have. After that one by one dir those. Find where your IOS is located and boot that specific device(could be flash1 for all we know).

If that doesnt work out for you, do a tftpdwnld

Rick,

Thank you for your assistance!

The tftpdnld process detailed in your link:

https://www.cisco.com/c/en/us/td/docs/routers/access/1900/software/configuration/guide/Software_Configuration/appendixCrommon.html#pgfId-1015120

resolved my issue.

just post the output of dir

maybe the file is corupted

take a look at the filesize

Richard Burts · ‎01-22-2019

It might be helpful to know why the boot of the new image is failing. The best way to do that would be to try booting again from the image in flash and then post all of the output during the attempt to boot.

But it is more important to find a way to boot successfully. It is not clear why the attempts to boot using usbflash are not working. Perhaps it is a problem with the image put onto usbflash? Perhaps it is a problem with usbflash? Perhaps we can solve that problem. Or perhaps a different approach might work. I have used tftpdnld to recover from failed attempts to boot from flash. This uses an image on a tftp server which has a connection to the router and loads it to the router.

I can confirm that the file is not corrupted. I used the Md5Checker tool to verify.

SCOTTA63123 · ‎01-22-2019

On second thought, I guess the image could have got corrupted upon transfer. I ran Md5Checker prior to transfer.

See this link to a discussion which seems similar to your situation. The issue in that discussion was that the image used was not appropriate to the platform being used. Might be that you need to try a different image file.
