"Lost pictures after iOS failure (no backup)"に関する回答The most important thing you need to know about data recovery is that data recovery is possible only if the lost data is not overwritten. Conversely, if the lost data is overwritten, you will not be able to retrieve the data. As far as I know, dr.fone does a good job of data recovery, as you can see from some data. Moreover, after three factory resets, your picture is likely to have been overwritten. You can try other iOS data recovery tools to verify, such as iMyfone D-Back.
"Recovering lost files from emptied trash."に関する回答The best solution has lost the page. There are still some ways to try before using the data recovery tool. For example, use the Mac-specific Time Machine feature: 1. Start "Time Machine" > select a way to transfer files and continue. 2. Select "Backup" to confirm the action and continue. 3. Carefully confirm the time and date of the backup and select the appropriate backup. 4. Select the file you want to restore and click “Continue” to start the transfer process. After the transfer process is over, check if your file has been restored. If it hasn't been recovered, don't hesitate to choose a reliable data recovery tool to recover lost files from emptied trash as soon as possible.
