Can't install any roms :(

[Firefox123]

I rooted my s2 with super one click, and after installing cwm, I couldn't install any roms, like villain rom 3.0 and I kept getting the following error message in recovery mode
-- Install /sdcard ... Finding update package... Opening update package... Verifying update package... E:signature verification failed Installation aborted.
Any idea why?

Try rooting again with this guide

done a wipe before trying to install??

and as shotgun suggested, may be better to try the chainfire method of rooting - i tried superoneclick in past and had problems, chainfire always seems to work

Also try booting into recovery and turn off signature verification. That's why it is failing to flash
