If you want to be 100% sure then you could always install Kmeaw yourself.
1) Get a USB drive in your computer and put an OFW 3.55 in this folder on the USB (PS3>UPDATE>PS3UPDAT.PUP)
2) Go to System Recovery(Hold down the PS button while it is off until it turns back off, then hold it down again until you hear 2 beeps in rapid succession)
3) Go to update firmware and install the OFW
4) Do steps 1-3 again only instead of OFW 3.55 put on Kmeaw(Or CFW of your choice) CFW in step 1.
5) There you go, Kmeaw CFW for sure.
