You have chosen the wrong chip to backup, it is a common mistake that many inexperienced people do. The file that you backed up is the thunderbolt firmware, the chip is 1MB (1024KB) ,but your backup is 1025KB. The file is corrupt now because you chose an OTP chip , or the programmer did with the Auto-detect. 64 bytes have been added to the end of the file and deleted from the top.

Don`t erase that chip and don`t try to flash the backup back to it, find the real bios chip. When you find it choose the chip manually, the Autodetect setting is very poor, and don`t choose an OTP chip. I assume you`re using a cheap nasty CH341A/EZP programmer

Hi SMDFlea,

Thanks for your reply, So, I don't touch the saved chip, but I look for another bios chip on the motherboard, is that it?
I still use the same CH341A/EZP programmer?
Or do you have another model to recommend? Thanks.
