How to restore the deletion of iphone7 SMS?

There are only two steps: the first step is to export the sms.db file of Apple's mobile phone short message database to the computer through iTools software, and the second step is to use Louyue mobile phone short message recovery software to view and recover it. 1, open the "iTools" software (you can search, download and install it online first), and connect the mobile phone with the data cable of the computer. Then click the "Info" tab at 1 in the figure below, and then click "SMS" at 2 places. At this time, the software will try to load all the SMS data in the mobile phone. It takes ten seconds to several minutes to load. If nothing is found after loading, please close the itools software, then reopen it and try again. After loading, click the "Backup" button three times to export the SMS database file sms.db from Apple's mobile phone to a folder on your computer. 2. Open "Lou Yue SMS Recovery Software" (you can search and download it on Baidu), click "File" at the arrow below to open the SMS database file menu and open the sms.db SMS data file just exported. 3. The undeleted SMS content in Apple's mobile phone is displayed on the interface of the software. We can click the menu "File" and "Restore Deleted SMS" to restore the deleted SMS. 4. After a while, the SMS deleted on your Apple phone was successfully recovered. The interface is as follows: I tested my own iPhone6 and an unused iPhone4, and later borrowed my friend's iPhone 5 and iPhone 5s, which can be successfully restored. In addition, I installed IOS9 beta on my iPhone6, which can also be restored, so this method should also be applicable to iPhone6S and iPhone6S Plus which have just been listed recently.
