I cannot restore my Wii U..

First I get error code 1601 2215 with Mii character stuck.

Then I installed Isfshax on my Wii U.

After that, I dumped Seeprom and OTP

and used MLC and SLC on my PC with MLCdownloader
And moved all MLC and SLC files to the SD.

Patch SLC and boot IOS (SLC) failed

It gives the error message
aancast: reading 0xdfd200 bytes from Slc:/sys/title/00050010/1000400a/code/fm.img
I formatted the SD card two or three times. Got a new SD card, put the files on it, same error again.
Every time I put the SD card in the Wii U, I got this error message. After putting the SD card into the PC, I see that some files have crashed.

What can I do to restore my Wii U?
I want to thank everyone.
