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?
Solved! Go to Solution.
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.
I'm still unsuccessful. Trying to update my 4331 from 3.x to 16.x and facing this error and booting witht he old one.
