LBP3 Filesystem Mounting problem [8001002b]

I was trying to play LittleBigPlanet 3 on the RPCS3 emulator by following this tutorial.
However upon trying to boot up the game it shows "Filesystem mounting failed" instead.
I tried lots of methods even re-dumping the game as well, but to no avail.

Can anyone explain in detail and give me a solution.
I had this problem since yesterday.

Missing log file, regardless, this error always means either corrupted base game or improperly updated, missing some update in the update package sequence.
