1841 not loading BIN from TFTP in ROMMON

Hello All,

 

 I've recently purchased a few 1841 routers for a home lab while I study for my CCNA.  The routers were purchased off of eBay, and all of them were locked and requiring login before getting to a command line.

 

I was hoping it would be as simple as putting the CF cards in a reader, wiping them, and transferring a fresh BIN.

 

After doing that I get the error:

loadprog: bad file magic number: 0x0
boot: cannot load "flash:"

 

So then I tried to load the BIN via TFTP. 

My first attempt was with TFTP64, I would continually receive the error:

Ack block 65535 ignored (received twice)
TIMEOUT waiting for Ack block #65536

 

I then tried Solarwinds with a similar result:

Dropped because peer didn't respond

 

These failures happened repeatedly, with different Ethernet cables to isolate any other possibilities of failure.

 

The one router that does boot up continually brings me to this dialogue:

program load complete, entry point: 0x8000f000, size: 0x2c3fe90

Re: 1841 not loading BIN from TFTP in ROMMON

Hello,

 

I am not sure where you are in the process, but is there a valid IOS on your CF card ? If not, can you put the bin file on the CF card and the boot from flash (boot syste flash) ?

Re: 1841 not loading BIN from TFTP in ROMMON

Hi Georg-

I attempted to do that on two of the routers that ultimately led to that having flash boot issues. I'm having a hard time finding the bin files available for download. Wanted to try and unlock this one before rendering it completely inoperable like the other two.

Thanks for the help.

Hi,

This is a duplicate post and we already gave an answer that downloads a fresh copy of IOS and verifies MD5 value with your downloaded file and Cisco website. Upload this new firmware to your router.

Re: 1841 not loading BIN from TFTP in ROMMON

Hi Deepak-

 

The site says the files are no longer available.  Is this due to my new account type/not being a partner?  it gives the ame error on all bin files.

 

Thanks so much,

Sam

Hi,

Yeap, Cisco has deleted the old IOS.
