Wp Nokia phone has been reset, and the problem phone has been restored.

Hello, the mobile phone I use is also Nokia's? Lumia620, update to WP8. 1? Denim

First of all, you need to know the synchronization mechanism of WP mobile phone system.

As you must know, a Microsoft account is essential in the use of WP mobile phones.

This account can provide you with credentials to download applications and synchronize personal data in the official app store.

Back to your question,

If you make sure that your phone address book, SMS and other important personal information are synchronized to the network before resetting,

Then don't be afraid. It doesn't matter if it's not restored. After logging in to your original Microsoft e-mail account, connect to the network. Find your account name in Settings-Email+Account, press and hold, click Sync, and then open the backup of "Application+Settings" and "SMS" in Settings-Backup.

If you are not sure that all your personal data have been synchronized to the network before resetting, I suggest you click Backup before restoring, then synchronize your address book and SMS to the network according to the two settings I just mentioned, and then reset or do other operations voluntarily.

Note: After entering "Settings-Backup-SMS" and clicking SMS, there is an option of "Download SMS in the following time periods". I suggest you choose "anytime" so that you can synchronize all the messages, because you have this mobile phone. At present, the earliest text message in my mobile phone is 20 13 1 month.

Finally, questions are welcome.
