Compressed firmware archive of 4.18 MB labelled only as Lenovo V310, with no exact variant, board number or version in the name. Because the V310 series came in several sizes and platforms, check the motherboard code printed on the PCB before using it. After extracting the RAR with 7-Zip or WinRAR, compare the image size with the flash chip capacity. Use a programmer such as a CH341A to read and save the existing chip before writing. Treat this file as unverified until it matches your board.
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 @afsbiosfree. Enginerys does not host this file.
