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.
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 (channel #flashrom) or
mail, thanks!"

Error screenshot here and below.

Hope you can enlighten me on this as i have used the latest flashrom version. Thank you!
