Firmware dump for the Zyrex Sky EP1210 in grey, from main PCB P10BD, with U14 most likely the designator of the flash chip that was read; packed as an 815 KB RAR. Small netbook and tablet boards like this are often revived by rewriting their SPI or similar flash with a programmer. Verify that the chip at position U14 on your board matches and that the dump size equals its capacity. Read and keep the original contents before writing, because a mismatched image can leave the device unbootable.
