Question : IOS update for cisco871 router

Hi Frnds,

I am using CISCO 871 Router for my network. recenly I found a problem whenever I go to configure it then it's showing RAMMON 1 mode. For this reason I am trying to update the IOS of this Router through TFTP server, it's took 4.43hrs. On that time it was updated properly, and without any problem I configure it. But when I restart it by manually / by command "reload", after that it again goes to RAMMON mode. And again by this procedure when I update it then it showing full configuration which I configured firstly.

And now you tell me what I am doing wrong.

Thank's
