871 will not enter rommon after flash upgrade.

Hello,  i tired to upgrade the flash memory on my 871.  i have tired to send single break and removing the flash card to drop the 871 to rommon.  but no luck, all i get is the below error.  i have try restart button on the back and get the same results.  Any idea on how to get the router into rommon mode so i can place the IOS  on the flash?

Hi jeremy crews

You post your question in a wrong forum, post in " Network Infrastructure > WAN, Routing and Switching". You can move your post using the actions panel on the right.

871?

Look at the back.  In the middle of the back panel and on the bottom is a small "Reset" button.

Power down the router, push-and-hold-down the reset button, power up the router and count to 15.

Ok, you/ve got two problems.

Firstly, there's either NO IOS or the IOS is corrupt.  Finally, some smart aleck decides to disable password recovery.  We'll tackle them one at a time.

For the IOS, follow this link:  Disaster Recovery with TFTP Download

Okay, well, I cannot get it to go in to rommon to use the disaster recovery.  All it seem to do is loop make and model info then the no bootable flash message.  any idea what happening or what I may be doing wrong.
