Xiaomi Mi 9 e Mi 9 SE are certainly the smartphones of the desire of the Mi Fans, because of the good hardware offered at super competitive price but also for the performances that can be obtained from the triple camera with the installation of the GCam Mod. But many feel the desire to push the two devices to the limit, resorting to modding, an operation for which the unlocking the bootloader, the recovery flash TWRP and obtaining the root permissions. So let's see together how to do it on Xiaomi Mi 9 and Mi 9 SE.

IMPORTANT

The described procedure presents complex operations which, if performed incorrectly, could damage your device. It is recommended to run it only by users who have gained good experience in modding.

Unblocking the bootloader

This is a really important aspect for an Xiaomi smartphone and, that could definitely come in handy in the life of the device. The operation, unfortunately, although it is immediate in practice, provides for a wait of 360 hours (on average). However it is good to equip yourself with a PC Windows with driver ADB e fastboot, as well as a USB cable for connecting the smartphone to the PC, which must have at least the 75% remaining charge. I invite you to click on the link below where you will find the detailed guide on unlocking the bootloader on Xiaomi terminals.

IMPORTANT

Xiaomi has imposed new safety-related directives, linked to modding. So it is recommended to do not install MIUI versions older than the one already installed, due to the Anti-Rollback mechanism that could permanently block your smartphone.

TWRP installation

It seems obvious to say, but the first step is to download the TWRP recovery for your Xiaomi Mi 9 or Mi 9 SE. You can search online or directly from the links below. Once you have downloaded the TWRP custom recovery, move it to the ADB certella on your PC.

3Connect the smartphone to the PC;

4In the "adb" folder, hold down the Shift key, click with the right mouse button and select "Open PowerShell window here"Or “Open a command window here”;

5Verify that the smartphone is detected with the command "fastboot devices", following which an alphanumeric string should appear with the writing "fastboot";

6Write "fastboot flash recovery -namefile-. Img"To start the installation of the TWRP (PS: instead of -file_name- you should write the name of the TWRP to be installed);

7Press and hold the Volume+ key and simultaneously use the command “fastboot reboot"To restart in TWRP mode;

THE STEP NUMBER 8 IS ONLY FOR XIAOMI MI 9

8From the TWRP disable the encryption and flash the Disable Force Encryption file, downloading the file from the link below.
