You have made two mistakes. First,you didn`t make a backup,and second you flashed to the wrong chip. The 25Q80 is 8 Mega bits, not 8 Mega Bytes. 8 Mega bits is 1 Mega Byte. Post a picture of the area where the 25Q80 chip is on the motherboard, there could be more 25Q80 chips, not sure without looking at the boardview/schematic. If it is near to the TI thunderbolt chip then you will need a dump to flash back to it before you do anything else. You`re not the only one who makes the same mistake, there is a thunderbolt 1MB backup at post 61.

I have reflashed 25q80 chip with original dump which I was assuming corrupt because it was only 1mb in size, but still not getting display, here is my original bios dump of winbond 25q128jv. Please help anyone
