The M35080 has special SPI pinout. So it is supported on GQ-3x,GQ-4X with special pin mapping from ZIF socket. It should be supported by ISP programming on GQ-3X, GQ-4X.

This chip is confirmed working when select 25C080 from the software on GQ-4X with adapter ADP-088

Or you can use a SOIC testclip or ADP-088 to mapping the pins as followings:
For now, you can select 25C080 from the software and maaping the pin as followings:

35080 ----- 25C080
pin 1 ---- pin 4
pin 2 ---- pin 1
pin 3 ---- pin 3
pin 4 ---- pin 2
pin 5 ---- No connection
pin 6 ---- pin 6
pin 7 ---- pin 5
pin 8 ---- pin 8
