A friend of mine she was frustarted in extracting WeChat chat messages from suspect‘s smartphone running Android 7.x. The situation is that no pattern lock/PIN/Password and USB debugging was enabled successfully. She tried every effort but in vain. No any commercial tools could help her to accomplish this task. I said to her:

“Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.” ―Thomas Edison

How to guarantee for extracting? All she need is:

1. Suspect‘s smartphone.

2.Install WeChat PC version on her laptop

3.A smartphone could be extracted by certain commercial tool without fail (Ex: support Bootloader mode or Smart ADB...)

I want her to take advantage of WeChat backup/restore function. Let‘s take a look at it as below pics.

Follow the steps as below:

1.Log in WeChat on her laptop with suspect‘s WeChat username and password. Don‘t forget the green check "Auto-sync" !!!

2. Click [Backup and Restore] on WeChat PC version.

3.Backup on PC then we could got backup files so as to restore to another phone we prepare.

6. Take a look where the backup file is.
