Installation of custom TWRP Recovery

Once the bootloader is unlocked, the next step is to install the TWRP (Team Win Recovery Project) which allows you to run Magisk to obtain root rights. For Redmi 9C (angelica), use the official TWRP version.

Installation instructions:

fastboot reboot recovery

If TWRP asks for a password when you start, it means that the phone has encrypted data. To turn it off, do a reset via TWRP (Wipe → Format Data), but note that all data will be deleted!

Getting Root Rights through Magisk

Magisk is a universal tool for obtaining root rights without violating the integrity of the systemless root, which allows you to use banking applications and games that usually block rooted devices.

Alternative method: root through ADB (without TWRP)

If installing TWRP seems complicated, you can get root rights directly through ADB and Magisk, a method that is suitable for MIUI firmware based on Android 10/11.

Instructions:

1. Download Magisk-v26.4.apk and rename it Magisk.zip.
