I have one 1841 router and just upgraded the IOS like below...
took backup of old IOS 12.4(15) upgraded the IOS from 12.4(15) to 12.4(24)T3 write the config no boot system boot system flash c1841-advsecurityk9-mz.124-24.T3.bin write the config reloaded the router
Now I completed whole required configuration. I took config backup I found in the running that there is no "boot system flash:c1841-advipservicesk9-mz.124-19.bin" line. Now I thought to added it again. I set boot system flash c1841-advipservicesk9-mz.124-19.bin I did whole required configuration write the config reloaded the router
Now when I checked the running config nothing is there all config is gone.
After this I just did small config and write the config and reloaded the router even now there is nothing everything is gone.
Experts can anyone have this kind of experience can someone help me in this why this router behaving like this. what could be the reason?
