To avoid blocking:
- Go to Settings โ Xiaomi Account โ Security.
- Click "Delete Account" (password required).
- Confirm the deletion via SMS or email.
โ ๏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 model | The risk of blocking after reset | Decision |
|---|---|---|
| Redmi Note 8/9 | High (blocking after 72 hours) | Untie the account + Fastboot dump |
| Redmi Note 10/11 | Medium (blocking after 24 hours) | Delete the account + disable Find Device |
| Redmi Note 12+ | Low (if account is untied) | Standard discharge is sufficient |
If you canโt delete your account (for example, forget your password), use Xiaomiโs official unlock tool: restore access. Donโt trust the โgooglersโ of the lock โ 80% of these services are either fraudulent or exploit vulnerabilities that Xiaomi closes with updates.
