Resetting Xiaomi Redmi to factory settings is a necessary procedure when selling a device, fixing system failures or preparing for firmware. However, the wrong actions can lead to data loss, locking the bootloader or even โbrickingโ the smartphone. In this article, we will analyze all the current methods of resetting (through settings, Recovery and Fastboot), nuances for models with a locked bootloader, and also give a checklist for saving important files before the procedure.
Redmi devices feature MIUI Recovery with stripped down functionality on some models (e.g. Redmi Note 10 Pro or Redmi 12), which means that a standard reset via the menu may not delete all user data, and for a complete "cleanup" will require Fastboot. We will explain in detail when to use, and warn against the typical errors that users turn to service centers.

If you sell a smartphone, after reset via Fastboot, execute the command fastboot erase frp - this will remove the binding to the Mi Account and protect your data.
7.Reset on locked devices (Mi Cloud Lock)
If you bought Redmi handheld and it requires the data of the previous owner, there are 3 legal ways to unlock:
- Contact the seller and ask to untie the device through the personal account.
- Provide a check to support Xiaomi (if you have officially purchased it).
- Reset via Fastboot (if the bootloader is unlocked):
fastboot erase userdata
fastboot erase frp
fastboot rebootIf the bootloader is locked, unlock it through the Mi Unlock Tool (requires Mi Account binding to the device for 72 hours). On Redmi models after 2020 (Redmi Note 11, Redmi 12) may require official permission from Xiaomi.
On devices with a MediaTek chip (such as Redmi 10C), the SP Flash Tool with auth-file firmware is sometimes used to bypass the Mi Cloud Lock. However, this method is risky - if mistaken, the smartphone can turn into a "brick".
