Hello every one!!<br />
<br />
I have cisco 3620 router. I made a mistake when I upgrade the software. my previous image was c3620-i-mz.120-4.T. I erased it and copy the image c3640-i-mz.122-19a.bin from TFTP server. After I finished, I reloaded it. But when it boots, it says &quot;wrong system software for this hardware&quot; &nbsp;continously so that it can't start. How can I correct my problem please? or how can I copy the previouse image to my router from TFTP server? Actually I have taken back up the flash image before I upgraded.

wrong system software for my router (cisco 3620)

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
