ISR 4331 does not boot to the image specified

[enewburn1]

New to IOS-XE but I have a ISR 4331 with two images on the flash. I've changed the configuration register to 0x2102 and I have the

boot system flash:isrxxx

in the startup config. The new image is listed before the old image in the config - but every time the router boots to the old image. Any thoughts?

Mine keeps resetting and unable to get into the IOS.

Console into the appliance and reboot.  Create a new thread with the output from the console and we'll try to help.

autoboot: boot failed, restarting...

My config is this way:

boot-start-marker
boot system flash bootflash:isr4300-universalk9.16.09.01.SPA.bin
boot system flash bootflash:isr4300-universalk9.03.16.04b.S.155-3.S4b-ext.SPA.bin
boot-end-marker

Any idea?

There could be two issues:

1. Change the ROMMON

2. Could be an image copy issue.Try to download the image again.

Did you upgrade the ROMmon?
