Case was solved already. But please create new layout for future cases.
This case use new XOR for Phison. I meet in many cases so far. Uploading dumps + XOR.
Second dump is practically empty. MBR and FAT is erased. After remove XOR use solution:
Mix
Input
Order 0
Block Pair
Block 0x204000
Page 0x2000
Block Cut
Block 0x400000/0x8000
Assembler
Raw
Block Size 0x400000
