I'm getting an Error 256 when trying to back up my iPhone in Decipher TextMessage
No ratings yet.
The Error (-256) when attempting to make a backup of your iPhone via Decipher TextMessage is usually an indication from the iPhone that it lost USB connectivity during the backup.
Most of the time when we see this error, the fix is to swap out the iPhone cable. If you have another cable handy, please use that for the next try. Likewise, if your PC or Mac has more than one USB port, please change USB ports as well. If the phone is plugged in to a USB port on a computer monitor, keyboard, or USB hub, please plug it directly into the computer instead if possible.
After following those instructions, reboot both the PC or Mac and the iPhone https://support.apple.com/en-us/HT201559 and then try the backup again.
If it is still not working for you, please use that contact support button in the backup window within the program so the new error log fills in for us to review. You can also try backing up in iTunes (Windows) or Finder (Mac) to see if that works. If the backup completes there, then run Decipher TextMessage and it will read in the iTunes/Finder backup and you do not need to backup in Decipher TextMessage.
If you still have troubles, you can contact us via our Decipher Tools Support page and we will write you back to assist!
