Unlocking your bootloader using Termux allows you to modify your Android device without a computer
. This process essentially involves using one Android phone (the "Host") to send commands to a second phone (the "Target") via a USB OTG connection. Requirements Host Device : A phone with Termux:API app installed. Target Device : The phone you want to unlock.
: A USB OTG adapter and a compatible data cable to connect both phones. Data Backup : Unlocking the bootloader will erase all data on the target device. Step 1: Prepare the Target Device Enable Developer Options Settings > About Phone Build Number seven times. Enable Key Settings Settings > System > Developer Options , toggle on: OEM Unlocking USB Debugging Enter Fastboot Mode : Power off the target device, then hold Volume Down + Power until the Fastboot logo appears.

Unlocking an Android bootloader using Termux—often referred to in community guides as the "Hot" or "PC-less" method—allows you to perform the unlock by using a second Android device as a host instead of a computer . This is particularly popular for Xiaomi, Redmi, and Poco How the "Termux Hot" Method Works
The process uses a second Android phone to act as the "master" device, sending fastboot commands to the "target" device through a physical connection. Physical Setup : Connect the two devices using a USB data cable and an OTG adapter (connected to the "master" phone). Environment on the master device from to ensure you have the latest packages.
: Install ADB and Fastboot tools within Termux using specialized scripts or repositories like MiTool on GitHub : Boot the target device into Fastboot Mode and use the master device's Termux terminal to run fastboot flashing unlock or device-specific vendor commands.

How to Unlock Bootloader Using Termux Hot (No PC Method) Unlocking an Android bootloader traditionally requires a PC and the Android SDK Platform Tools. However, a "hot" method using Termux allows you to perform this task using only a secondary Android device. This guide explains how to set up your mobile environment to unlock another device's bootloader without a computer. Requirements and Preparation
Before starting, ensure you have the following hardware and software ready:
Host Device: A secondary Android phone with the Termux app installed.
Target Device: The phone you want to unlock. It must have OEM Unlocking and USB Debugging enabled in the Developer Options.
OTG Connection: A USB OTG adapter and a data cable to connect the two phones.
Backup: Unlocking the bootloader wipes all user data from the target device. Step 1: Setting Up Termux on the Host Device unlock bootloader using termux hot
Open Termux on the host device and run these commands to install the necessary tools: Update Packages:pkg update && pkg upgrade Install wget and API tools:pkg install wget termux-api
Install ADB and Fastboot:You can use a script to install these tools without root. A popular option is the Termux-ADB script:wget https://githubusercontent.combash install.sh Step 2: Connecting the Devices
Connect the host phone to the target phone using the OTG adapter (host side) and the data cable.
On the target phone, a prompt will appear asking to "Allow USB Debugging." Select Allow. In Termux, verify the connection:adb devices Step 3: Entering Fastboot Mode
Once the devices are communicating, reboot the target device into its bootloader: Run the command:adb reboot bootloader
Wait for the target device to show the Fastboot/Bootloader screen. Confirm the connection in fastboot mode:fastboot devices Step 4: Executing the Unlock Command
Depending on your device manufacturer, use one of the following commands: Standard Android/Google/Motorola:fastboot flashing unlock Older or Specific OEM Models:fastboot oem unlock
On the target device, a warning screen will appear. Use the Volume keys to select "Unlock the bootloader" and the Power button to confirm. Special Case: Xiaomi Devices
Xiaomi devices require a specific "hot" tool to retrieve an unlock token from their servers, as they don't use standard fastboot commands.
Account Binding: You must bind your Mi Account in Settings > Mi Unlock Status and often wait for a timer (7–30 days).
Termux MiUnlock: You can use specialized scripts like termux-miunlock to perform the final unlock without a PC once the waiting period is over. Troubleshooting Common Issues
Unlocking Android Bootloaders Using Termux: A Technical Overview
The process of unlocking an Android bootloader traditionally requires a PC to execute Fastboot commands. However, advanced users can now use Termux on a secondary Android device to act as the "host" controller, effectively replacing the computer. This method is particularly popular for Xiaomi, Redmi, and Poco devices. Core Requirements To perform this "No-PC" unlock, you need:
Host Device: A secondary Android phone with Termux and the Termux:API app installed. Target Device: The phone you wish to unlock.
Physical Connection: A USB data cable with an OTG adapter to connect the two phones. Unlocking your bootloader using Termux allows you to
Software: Modified ADB and Fastboot binaries (e.g., termux-adb) that support USB communication via Termux. Standard Procedural Steps
I need the device model and Android version to give exact steps; I'll assume a common Android phone with an unlocked bootloader path via fastboot. Steps below use Termux on-device and require a PC only if your device blocks fastboot over USB from the phone.
Warning: unlocking the bootloader erases all data and may void warranty. Proceed only if you accept that.
Prerequisites
pkg update -y
pkg install openjdk-17 git wget unzip -y
pkg install android-tools -y
(android-tools provides adb/fastboot.)Method A — Unlock via fastboot from Termux (device supports fastboot mode and USB OTG with host capability)
adb reboot bootloader
or power-button combo.fastboot devices
fastboot oem unlock
fastboot flashing unlock
Method B — Using PC (recommended if Termux cannot access USB)
adb reboot bootloader
fastboot devices
fastboot flashing unlock
Confirm on device.Vendor-specific notes (high-level)
If you tell me your device model and Android version I will give a precise, step-by-step command list and vendor-specific caveats.

The idea of unlocking a bootloader using a single “hot” Termux command is wishful thinking. It belongs in the same category as “free Instagram followers” or “RAM downloader” apps.
Don’t brick your phone. Don’t pay for fake scripts. Instead:
Termux is an incredible tool for developers, pentesters, and tinkerers. But it cannot perform hardware-level bootloader exploits on modern devices.
Stay safe. Mod wisely.

Step 1: Prepare Your Device
Open Termux on your Android device.
Grant Storage Permission: You might need to grant storage permissions to Termux. You can do this by going to Settings > Apps > Termux > Permissions > Storage.
Update and Upgrade Termux Packages:
pkg update && pkg upgrade -y
Install adb and fastboot in Termux:
adb and fastboot in Termux if you're planning to use the computer for these steps. However, if you wish to do everything from Termux, you can try installing them via:
pkg install adb
Step 2: Enable OEM Unlock (if not already enabled)
Settings > Developer options and look for the “OEM Unlocking” option and enable it.Step 3: Boot into Fastboot Mode
Using Computer:
adb reboot bootloader and press Enter.Using Termux (sometimes direct fastboot might not work):
adb reboot bootloader
Step 4: Unlock Bootloader
Using Computer:
fastboot oem unlock
or for newer devices:
fastboot flashing unlock
Using Termux (rarely used due to complexity):
fastboot oem unlock
or

Not for unlocking. But once unlocked, Termux + pkg install android-tools lets you: Backup all data
