Can anybody help with a Ubook X bios “.bin” file…?

Hi Im looking for help if anybody has a backup of their bios “.bin” file they can show me so I can compare to the bios file that Chuwi sent me and try to figure out what section I need to flash to my bios chip for it to work again. I’m using a ch341a programmer that clamps onto the chip and it’s a winbond 25x20clng. The size of the chip is 256kb and the bios file they sent me is 8mb but it won’t fit on the chip of I try flashing the whole file so i need help to find the section of hex code in the bios file that is the right part to flash onto my bios chip to fix it… thank you!
