Firmware archive, 3.46 MB RAR, for board 71R-A14RV4 revision 4.0 used in the T840, containing dumps for chips U11 and U12 with a 4 MB capacity mentioned in the name. The board number itself does not reveal the manufacturer with certainty. Use these images to reflash the SPI chips with a programmer after corruption. Confirm which dump belongs to which chip position, save the original contents first, and make sure each image size matches the flash part.
