I wasnt able to decrypt your files. I believe DJI has updated the AES and or IV key. Depending on the firmware you were running. Im grasping at straws here and maybe someone with more knowledge can shed some light but you may be able to root your RC and get it to tell you the new key. you'll have to google how to root the device as I didnt root mine and i dont think they will talk about rooting on the forum.I ve sent the files to mryeje. As soon as he gets info, I ll post it or he will. Looking forward to find the drone.

Sorry I couldnt decrypt them. I know the script works because I just decrypted my old fatal.log file just now.
