Hi,

I have the same problem. I bought a slim ps2 a week ago. While booting it read Infinity v.1.39 so i assume(d) it had a Matrix Infinity chip. I read here that there is a new firmware, checked Matrix website and saw my version there too. So i couldn't go wrong right??

Well i upgraded the fw to 1.45 and now circle triangle doesn't bring the chip menu anymore. This Matrix logo pops up and the thing freezes.

Anyway i can undo this upgrade?

Anyone has a Modbo fw image i can use?

Thanks in advance.

P.S.: Doesn't this thing need to do a checksum before it upgrades fw? Shouldn't it have told me that the chip is not intended for that fw?
