1. Backup: What and How to Save

The first and most obvious step is backup, but for most Xiaomi Redmi Note users, just copy photos to Google Photos and consider it done, and in practice, it only covers 10 percent of potential losses.

  • ๐Ÿ“ฑ Contacts and call log: Export through Contacts โ†’ Settings โ†’ Import/export: Donโ€™t rely on Google sync alone โ€“ it may not work when reset.
  • ๐Ÿ”‘ Passwords from the browser and applications: Use Settings โ†’ Passwords and security โ†’ Autocomplete for export (if synchronization with Mi Account is enabled).
  • ๐Ÿ“Š System settings: B MIUI There is a hidden function of backup settings through Settings โ†’ The phone. โ†’ Backup (requires a Xiaomi account).
  • ๐ŸŽฎ Save Games: For cloud-saving games (such as Genshin Impact), link your account to an email. Local saves copy through My files โ†’ Games.

Copying files on a PC
I use third-party software.
I never make a backup.

If you have a Redmi Note 10/11/12 plug-in USB-C, use OTG-It's faster than Wi-Fi transmission, and it eliminates the risk of data loss when you break the connection.

2. Xiaomi account unbundling: why it's critical

Mi Account is not just a way to sync, but a digital lock on your Redmi Note. Once the device is reset in the service, the phone may require a login/password from the previous owner. If you forget the data or the service center "forgets" to untie the device, you get a brick.

To avoid blocking:

  1. Go to Settings โ†’ Xiaomi Account โ†’ Security.
  2. Click "Delete Account" (password required).
  3. Confirm the deletion via SMS or email.

โš ๏ธ Note: If you use Find Device or Second Space, you need to disable them before deleting your account, otherwise your phone will be locked 24 hours after resetting.

Redmi Note modelThe risk of blocking after resetDecision
Redmi Note 8/9High (blocking after 72 hours)Untie the account + Fastboot dump
Redmi Note 10/11Medium (blocking after 24 hours)Delete the account + disable Find Device
Redmi Note 12+Low (if account is untied)Standard discharge is sufficient

If you canโ€™t delete your account (for example, forget your password), use Xiaomiโ€™s official unlock tool: restore access. Donโ€™t trust the โ€œgooglersโ€ of the lock โ€“ 80% of these services are either fraudulent or exploit vulnerabilities that Xiaomi closes with updates.

What to do if your phone is locked after repair?
If Redmi Note requires an old Mi Account after repair, contact Xiaomi with a check for repair and a passport. Unofficial services do not have access to the lock database. 90% of the time the problem is solved for free if the repair was carried out with an authorized partner.
