BIOS image for the Lenovo ThinkPad X1 Tablet built on the Wistron LGF-1 board, revision 15218-5, packed in an 8.26 MB RAR. It serves to recover a tablet that fails to boot after firmware corruption or a failed update. Check the archive contents and match the image size with the SPI flash chip fitted on the board. ThinkPads store serial and system information in this chip, so read and keep the original dump before writing a replacement with a programmer.
