You can perform the upgrade/downgrade from rommon mode, and here is the procedure for your reference:

Hope that helps.

Sounds good.....what commands can show me what is saved on my flash so i can input the proper file name.....

Good question, try "dir", otherwise, feel free to upload a new copy of the software via TFTP.

[Add] It might have been corrupted when you perform the upgrade earlier, so a fresh copy of the software would be preferred.

dir doesnt work

Thinking I might have to erase the flash......so if I do that can I do a TFTP download?

Have a link on how to PROPERLY do tftp download.......I think this time I will follow the steps instead going Rambo on my own.....

restart router, when loading config break initialization:

router will enter rommon, enter following cmds:

>confreg 0x2142

(don't not load saved config "n", when prompted)

router is now reset then save new config:

#config t
