Firmware for a Philco 10B tablet whose board is marked 71R-B11E14-T820, archived as a 618 KB RAR. The name gives no chipset, flash type or version, so match the board code printed on the PCB before use. Small tablet firmware like this is usually written to the device to recover from a boot loop or a corrupted system. Whether you use an external programmer or the SoC vendor flashing tool depends on what the archive actually contains. Keep a backup of the existing firmware when you can read it.
