What should I do if the SMS backed up by Xiaomi mobile phone Baidu Cloud cannot be recovered?

This must not be solved by restarting.

I think the information may be lost. Don't use your mobile phone or network disk for backup in the future.

Really unreliable. This happens all the time. Either it's gone or it's all gone.

The data I am backing up with Appbo is on my computer, which has happened several times. All the problems with my mobile phone were recovered from it, and nothing happened. If you are interested, you can install an application treasure in your computer, connect your mobile phone, and find data backup in the toolbox in the lower left corner. Just two minutes. Be sure to back it up at will in the future, so that if there is anything wrong with your mobile phone, you can save a lot of trouble. The data in it can be restored by restoring.

See if it helps you.
