Hi ! I've got the exact same issue with my XT5 and 16-55 f2.8 II ... My xt5 is on 4.31 Lens is 1.00 I tried it with both files (XFUP0019.DAT and XFUP0064.DAT), together and individually on the SD card, formatted it everytime I tried a new combination. My guess is that having access to older firmware updates could help, since there is a big jump (8 updates) between 1.00 and 1.33 Does anybody know where i could find the older firmware update files ? Thanks, Théo
