Help required for GD25LB64C

[CyberPK]

Hello, I'm trying to read and write the flash memory into a GD25LB64C which
is automatically recognized as GD25LQ64C.
I'm using a pickit2 setting 1.8V and flashrom 1.0 compiled from source
release.
I'm using the -VVV flag, but the read process remains stuck in reading and
the writing process remains stuck in "reading old flash chip contents".
I've also tried to erase the content using the -E flag in addition to the
verbose  -VVV flag and I can see the slow advancements through the
addresses appearing to n the screen.
But I'm still unable to read or write. What I can do? Any idea?
Regards
