[NOTE]: use "copy http://hostname.cisco.com/c800-universalk9_iox-mz.SPA.155-1.T1.bin flash:" to download the image through http.

3. After download the image to flash of C819. Run below to boot the C819 from the image:

I'm missing something ridiculous, I must be.  But this does not work for me on my C819HG-4G.

The router just keeps booting into 153.  Do I need to remove the old image...??

[Levi Iiams]

GAH!

Yeah, so as I said, something really simple...

#conf t

(config)#config-register 0x2102

Brand new router.

I had to do the following:

819(config)#boot system flash flash:c800-universalk9-mz.SPA.155-1.T1.bin
