Firmware dump for the Lenovo Miix 310-10ICR tablet, marked ok in the name, which suggests a tested working image. The 1.33 MB rar gives no board number, so match the model and the PCB markings yourself before use. On Atom-based tablets like this one, a dump is usually written to the SPI flash with a clip and programmer when the unit no longer boots. Read and archive the original contents first. Check that the image size matches the chip's capacity before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
