All PS3's start with CECH. It's the letters and numbers afterwards that matter. Based on supposed 40Gb drive, it's possibly phat.
That said, until bguervilles toolkit is available again, now isn't the best time CFW:ing PS3's. Lots of brick prone clone websites. Although, if your console is hackable phat/slim, there might be alternatives for installing CFW without toolset as it is on low OFW version.
//EDIT
All phat units are hackable with CFW, as are some slims. The super slims cannot be CFW:d, but there is HEN option for all PS3's. (HEN=Homebrew ENabler)
Wow fakes sites ? That seems weird and sad.
I've a phat one 100% (https://i.pcmag.com/imagery/articles/06M5d6qAkj5ah3SQlpmYi4K-1..v1569483791.jpg) <= reference of the PS3
I'm curious now, what I'd need to make it possible ?
Thanks o/
