Copying flash IOS to 2851

[rma20001]

Hey all - Cisco noob here looking for some help. I have a 2800 that has lost it's flash file and I am trying to copy a new one to it via xmodem.

This is how it boots, won't get any further:
Readonly ROMMON initialized
boot: cannot determine first executable file name on device "flash:"
c2851 processor with 262144 Kbytes of main memory
Main memory is configured to 64 bit mode with ECC enabled


Readonly ROMMON initialized



This is my result when I try to copy the new bin:
rommon 28 > xmodem c2800nm-advipservicesk9-mz.123-14.T7.bin
Do not start the sending program yet...
File size Checksum File name

WARNING: All existing data in flash will be lost!
Invoke this application only for disaster recovery.
Do you wish to continue? y/n [n]: y
Ready to receive file c2800nm-advipservicesk9-mz.123-14.T7.bin ...
BB0BB0
Timeout waiting for data - aborting download...




is my syntax wrong in the line? Do I need to have the bin file in a certain folder?

I guess it looks like the router and PC aren't able to talk.

Go to the following link:

http://www.cisco.com/en/US/products/ps5854/prod_configuration_guide09186a00802c35e9.html

then go to the section:
Recovering the System Image (tftpdnld)
Follow those instructions and you should be able to load the new config via ethernet tftp instead of xmodem. Also make sure your flash is seated properly.

Thanks, I'll try to set that up.
Does tftp generally work better than xmodem?

 

[JOAMON]

tftp is via ethernet and xmodem is through the console port at 9600 baud.....slooooo

http://wwwwwwww.

Keep in mind that these commands are case sensative.....if the example is in uppercase then enter it that way....

Actually with xmodem you change the baud to 115200 (in both rommon and hyperterminal) and the syntax should be xmodem -c ios.bin. Then when it says ready to receive file....on hyperterminal you click on transfer (on top) then hit send file. When you do this a dialog box will pop up and under the protocol box you have to choose xmodem. Then browse for ios and just click on send. This happened to me recently and i my rommon didnt have the tftpdnld command. so i had to go the xmodem route. peace
