I recently got a BD-C5500 and soldered to the serial console. While looking around I tried to mount the mtdblock partitions, expecting it to either work or fail to autodetect the fs type and not modify anything. Instead, it seems to have corrupted at least two of the partitions -- flash0.ofefw0 and flash0.kernel.
From a boot log:

Anyone got any ideas, or a copy of the firmware/those partitions I could have?
Thanks!
