Reposting your messages to a flashrom mailing list. Are you sure that a contact of a clip - with a chip - is good enough? If a chip is hanging in the air and its legs aren't mounted to the motherboard, the legs are prone to a tiny bending and the contact is less certain. Do you have a DIP8 to SOIC8 adapter - to plug this chip directly to a programmer without a test clip?

Hello Mike,

I will rewire but so far it was good the first time but i broke one of the legs of the bios pin on the board why i needed to replace the entire bios chip. Now i am flashing directly to the chip itself. with a clip.

Are you sure that your (ISP? in-system programming) flashing set up is reliable? Short enough wires, etc.

Hello, 

I tried to change the flash chip of my old Toshiba satellite pro a50 a series with previous bios chip Winbond 25Q64CVSIG with a new Winbond 25Q64FWSIG and i am getting the error "No usable erase functions left.
FAILED!
Uh oh. Erase/write failed. Checking if anything has changed.
Reading current flash chip contents... done.
Apparently at least some data has changed.
Your flash chip is in an unknown state.
Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail flashrom@flashrom.org, thanks!"

Error screenshot here and below.
