Firmware dump for the Acer A315-53 on Compal board LA-E891P, platform code C5V01, taken from position UC3 and sized 4 MB. This board carries more than one flash chip, and the 8 MB UC2 image is the companion file, so each must be written to its own chip. Compal numbers boards in the LA-xxxxP pattern printed on the PCB. Read and keep the original contents first, then program with an SPI programmer, checking that the chip at UC3 is really a 4 MB part.
