If it is the data stored in the memory of the mobile phone, it is impossible to restore the machine without backing up the chat records/contacts. It is recommended to back up your mobile phone data regularly to avoid accidental loss.

If you need to back up the WeChat chat record, please operate: WeChat-Me-Settings-Chat-Chat Record Migration-Select "Migrate to an accessory device" or "Back up/restore the chat record with a computer" as required.

note:

1. Chat records need to be migrated via WIFI.

2. Due to the different versions of WeChat, the operation mode is slightly different.
