Which software to flash GIGADEVICE 25B127 chip
#1
Hello,

Which program should I be using to flash a GIGADEVICE GD25B127DSIG (25B127) chip?
This is the BIOS in my CyberpowerPC Gaming laptop (I7, RTX2070) which is a barebones Quanta NL5E with both CPU & GPU soldered on.

I have downloaded the CH341A programmers versions 1.18, 1.34, 1.38 - but none of these have the 25B127 in the chip selection list.

Any help much appreciated.

Thx,

Thank you for your reply.
I have tried various chips from the GIGADEVICE list then 'detect' but just get not recognised with 'FF' in the chip details.

The programs do not have any GD25B128Cxxx in the support list;

v1.18 = 25Qxxx / 25Fxxx / 25Dxxx / 25Txxx (I tried GD25Q128 but did not work)
v1.34 = 25Dxxx / 25Qxxx / 25Fxxx / 25LQxxx / 25Txxx 
v1.38 = 25Dxxx / 25LQxxx / 25WDxxx / 25WQxxx / 25VQxxx / 25Qxxx

I tried an old desktop motherboard and all the programs recognised and read the Winbond chip on it. So the CH341 & clip seems to be ok.

Which program do you have with GD25B128Cxxx in the chip support list?

Thanks,

No it doesn't detect anything when attached to the GD 25B127 chip, screenshot of each version;

They all 'detect' the Winbond 25Q80 chip;

GigaDevice GD25B127D is compatible with GD25B128C, GD25R128C, GD25R127C, GD25B127D, GD25Q128C, GD25Q127C.
Choose one of them manually in your program. Or try NeoProgrammer
