The message โThis operation will unlock the bootloader and erase all user dataโ on the Mi Unlock Tool screen causes panic among most Xiaomi, Redmi or other users. POCO. Because unlocking the bootloader is a must for custom firmware, root rights, or even official global software to be installed on Chinese versions of devices.

Why Xiaomi deletes data when unlocking the bootloader?
The reason lies in the security architecture. MIUI. The bootloader on Xiaomi devices is blocked by default to prevent:
- ๐ Unauthorized access to system partitions (including /data, where user files are stored).
- ๐ฆ Installation of malware through custom firmware.
- ๐ฑ Recovery of data from stolen devices (even after being reset via fastboot).
When you unlock the bootloader through the Mi Unlock Tool, the system automatically formats the partition. /data, stored:
- ๐ธ Photos and videos (including screenshots).
- ๐ Contacts, SMS/MMS call-book.
- ๐ฎ Application data (game saving, cache) WhatsApp/Telegram).
- ๐ Passwords from Wi-Fi and accounts.
However, not all data is permanently erased. SD-The card (if used as a removable drive) and some of the system logs remain intact, and the data is stored in the Mi Cloud cloud - but only if the sync was enabled before unlocking.

1. Unlocking through EDL (Emergency Download Mode)
A method for advanced users that requires:

- ๐ป PC with Qualcomm drivers and Mi Flash Pro.
- ๐ Firmware file in.mbn format (for example, firehose).
Advantages:
- โ No forced data resetting.
- โ It works even on locked devices (for example, after a failed firmware).
Disadvantages:
- โ Risk of damaging fees if incorrectly connected to test points.
- โ Requires soldering skills or a service center.
- โ On new models (Xiaomi) 13/14, Redmi Note 12) Test points may not be available.
Instructions:
- Take the phone apart and find test points (usually signed by EDL or TEST).
- Connect the wires to the points and USB-port.
- In Mi Flash Pro, select a firehose file for your model.
