Unsigned IOS images ??

Unanswered Question
Sep 9th, 2010

  I installed a new IOS load on my 2951 and but it failed to boot with the following error.

IOS Image Load Test

___________________

Unsigned Image Found, bailing out

Signature DID NOT VERIFY

boot: cannot load "flash0:"

  Is there something wrong with c2951-universalk9-mz.SPA.151-2.T1.bin?  Or is there additional steps with the 2951 that I haven't learned about yet.  This is my first 2900.

Thanks,

Greg

I have this problem too.

Please post the complete boot log.

Try breaking into ROMMON and post a 'dir flash:' and 'set'

The IOS may also be corrupt. May want to try downloading a fresh copy off cisco.com and reloading it on the flash

Have you resolved it?

Post the entire bootup process of your router.

Also post the output to the command "dir flash:"

Download the IOS again from the Cisco website.

Eject the CF from the router and use a multi-card reader to overwrite the file.

Hi,

As you can see from the logs you pasted the image is corrupted:

Signature did not verifySignature DID NOT VERIFYboot: cannot load "flash0:"

As the post above suggest, download the image again and use this link to check for any corruption in the image:

I have deleted the Image "c2951-universalk9-mz.SPA.152-1.T.bin" on the Flash

and load up the new Image "c2951-universalk9-mz.SPA.153-3.M.bin", but the Router

don´t leave the Booting Process and end in a Booting-Loop.

Please help

Thanks

Andi
