Firmware archive for an LDK-1 tablet mainboard numbered 13275-1, with the additional code 48.4E007-011. The 13275-1 style of number follows Wistron's numbering scheme, and 48.4xxxx codes are typically Wistron PCB part numbers. The roughly 8 MB package is used to restore the board's SPI flash with a programmer when the device fails to boot. Match the board and part numbers silkscreened on the PCB before use. Back up the current chip contents so the original data can be restored if needed.
