877 Router IOS Issue-Command needed to make the newly downloaded bin file my main flash file that the router now boots from?

We managed to wipe my IOS from my Cisco 877 Series router.Now using TFTP we have managed to reload the software and boot up the Router (previously we were stuck in Rommom mode).

If we power the router off and turn it back on and brought back to Rommom mode again and have to reload the IOS again. What command do we need to use to make the newly downloaded bin file my main flash file that the router now boots from?

What option are you using when you TFTP the IOS to the router? Are you by any chance using "tftpdnld -r" option? Please try the following:

Step 1: Upload the file via tftpdnld (like before)
Step 2: Boot the router
Step 3: Check the flash content and make sure that image is there.
Issue the command "show flash" at "Router#" prompt
Step 4: If the image is missing, copy the image
Issue the command "copy tftp flash" at "Router#" prompt
Step 5: Set the configuration register value to 0x2102
Issue the command "config-register 0x2102" at "Router(conifg)#" prompt
Step 6: Make sure that there is no boot statement in your configuration
Issue the command "show run | i boot system" command at "Router#" prompt and make sure that there is no output for that command.
