Small 512-byte data file, most likely an EDID dump for an LCD panel LP171WX2 with WXGA+ resolution, associated in the name with an i9300 and code T4976. Files this size usually come from the panel EEPROM that tells the graphics adapter the screen timings. It is used to restore a panel whose EEPROM is corrupted, causing no image or wrong resolution. Write it with an EEPROM programmer to the correct chip, and compare against the panel label before replacing anything, keeping the original read.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
