Re: [30 PH] ** 5x AVALON6 GIVEAWAY ** Kano CKPool (kano.is) [0.9% PPLNS] US,DE,SG
i forgot to state for S3 
tried the link for the s2 firmware i used from a forum post and github has disabled kano's firmware
EDIT
found the s3 firmware here
https://bitbucket.org/TheKano/cgminer-binaries/src/f5884bfece7a8dfd48550cb172272212459be51c/AntS3/?at=master
Any custom FW for S5? -- I am planning to get the S5 FW refreshed to do ckpool solo mining fulltime.
as far as i know kano stopped making firmware after s3
