Working way: W and Hold is high, Other SPI BUS.
First we send "RDSR" Command but MISO is low like no working, so I try send "WREN" and "WRSR"but is no working.

Hello,
Even if MISO is low after RDSR doesn't mean it doesn't work. Status register content = 0x00 will give you MISO = low.
Please try WREN + RSDR. You should have WEL bit = 1
(confirm your hexa command)

I find the answer.
your datasheet :
1.Before accepting the execution of the Write and Write Status register instructions, the
device checks whether the number of clock pulses comprised in the instructions is a
multiple of eight.
so: send“RSDR"+"0xff".
