If your X6100 is connected to wifi - open go to "File Browser" and download ADI file. You also can use radio IP address (from the WIFI screen) instead of `x6100` in the address.
Or you can turn off the radio, insert SD card to the PC/Mac and copy file from the DATA partition.
Sometimes Windows assign a letter only for the first (BOOT) partition. If you see only one partition in the explorer with boos.scr and 2 another files - open partition manager and manually assign a letter to the DATA partition (3rd on the SD card)
