Vellica B2200 - help installing openwrt newst version

For the life of me and I cannot install openwrt (newest version) on this router. I know some people have done this… can anyone assist?

I successfully did it on my b1300 convexa, with the local upgrade option. I tried exactly the same thing with different files for the vellica and I get an error that says the check Failed.

Any help would be much appreciated.

This is the error message I get:

Can you give me the link of the firmware?
