Whilst many PS3 owners had a problem with Waninkoko’s CFW, which resulted in bricks, some owners escaped fine, Waninkoko tried to find out what the problem was, now he is releasing version 2 of his CFW, here is a quote from Teknoconsolas:
Waninkoko is finalizing what will be their 3.55 CFW V2 and believe it will be released in a very short space of time (today … tomorrow …?). Be compatible with both FAT and Slim consoles and will include a new Payload, which currently can not reveal.
Teknoconsolas also reports that Hermes is working on CFW for 3.41, here is what they say:
For his part, and as we read in EOL, it appears that Hermes is by testing its own version CFW for 3.41, so users who do not wish to migrate still CFW 3.55 could also enjoy their own version of custom firmware.
