IR1101 boot issue

[padraignotlad]

Hello,

I was trying to downgrade the iOS on an IR1101 router from ir1101-universalk9.17.02.01.SPA.bin

to ir1101-universalk9.16.11.01.SPA.bin.  

I accidentally entered "boot system flash:/ir1101-universalk9.16.11.01.SPA.bin"

When I should have entered "boot system bootflash:/ir1101-universalk9.16.11.01.SPA.bin"

Now the router is in a boot loop because it can't find "flash:"

I've been able to ctrl+c to break and enter rommon> and manually boot, and then when I'm in the OS, I try to fix with the correct boot statement, but it doesn't take.

I've tried changing the boot statement by using the set command, but that doesn't save either.  Even when I type "sync" after.

How to I fix this?  I just want to forget about downgrading and load ir1101-universalk9.17.02.01.SPA.bin.

Thanks,

Padraig

Console into the router and reboot.  Post the entire bootup process.

Are you still having this issue?

My solution is to load the desired image to a USB drive, and plug it into the router.
If the router boots to rommon:
Boot the router from the IOS image on the flash drive

boot usbflash0:ir1101-universalk9.16.12.05.SPA.bin

then copy the image to the router:
copy usbflash0:ir1101-universalk9.16.12.05.SPA.bin flash:

then verify integrity:

verify /md5 flash:ir1101-universalk9.16.12.05.SPA.bin

verify the boot variable with:

show bootvariable

Remove the variabl;e you don't want with:

no BOOT system flash:ir1101-universalk9.17.06.05.SPA.bin

Add the one you want with:

boot system flash:ir1101-universalk9.16.12.05.SPA.bin
