Hmm, i've heard this doesn't work with slims, but i'm assuming that's just for stock 3.50/3.55 ps3s, unless someone has proof otherwise.
3.41 firmware with 3.55 coreos info0 would be better than *****, what's the point when we could just use 3.55.
I'll wait for more tests before i do this, but it looks like it's time to upgrade, activate psn dlc, backup files, and downgrade back to 3.41.
STOP! Before you ask questions... READ the first post! RTFFP = Read The F*cking First Post
