Hi,
since GD25LQ128D is marked as untested I like to share my success. I have an Acer TravelMate P215-41. The BIOS was bricked due to an update issue. I successfully reflashed the Bios on the GD25LQ128D (25LQ128DSIG) using a CH341A programmer [1] and flashrom. I removed RAM, hard drive, CMOS battery and accumulator and connected the clip direct to the mainboard using the 1.8V adapter. Read, erase and write was successful.
Kind regards Aaron
