Complete write operation failed

[mdshanto]

1 month ago i've installed Marshmallow 6.0.1 in my note 4. it was great. 2 days ago suddenly it lagged. it lagged often. i've re-installed another firmware but nothing happened. then i re-partitioned my phone with a pit file and nand erased all. now firmware is not installing. in different time it fails to write different files. even sometimes it says there is no pit partition. I've tried Odin different versions and also 3 different firmwares. nothing happened. Help me please. and thanks in advance.
