On the target phone, a prompt will appear asking to "Allow USB Debugging." Select . In Termux, verify the connection: adb devices Step 3: Entering Fastboot Mode

Unlocking a bootloader using Termux refers to a method where a secondary Android device acts as a "host" to send commands to a target phone via a USB cable and OTG adapter. This technique is popular for users who want to avoid using a PC or bypass manufacturer waiting times, particularly on Xiaomi devices. How the Method Works

The Target device will turn off and boot into a static screen (often displaying a fastboot logo, a broken Android robot, or text menus). Step 5: Establish Fastboot Communication

Some manufacturers, especially those using MediaTek chipsets, may require a different command.

Open Termux on the host device and run these commands to install the necessary tools: : pkg update && pkg upgrade Install wget and API tools : pkg install wget termux-api

If the target device is in Android OS, it should be listed as a device. If you see "unauthorized," check the target device screen for a prompt to allow USB debugging. Next, boot the target device into fastboot mode (usually by holding ). Then, verify the fastboot connection:

Before you begin, you will need:

If successfully connected, Termux will output a string of numbers followed by the word device . Step 4: Boot the Target Device into Fastboot Mode

The "host" phone is the one you will use to control the process. It does not need to be rooted.
