Unlock Bootloader Using | Termux Link

The "unlock bootloader using Termux link" is not a myth, but it is hardware specific. If you own a MediaTek-powered phone, Termux combined with mtkclient is a magical way to ditch the PC. For everyone else, keep a Linux live USB or an old laptop handy.

Have you successfully unlocked a bootloader using Termux? Let me know your device model in the comments below!

Searching for "unlock bootloader using Termux link" returns many misleading YouTube videos and shady Telegram channels. Let's clear up the reality:

Myth: You can run fastboot oem unlock in Termux on your phone and instantly unlock it. unlock bootloader using termux link

Reality: Termux runs inside Android. When you reboot to bootloader/fastboot mode, Termux stops. You need to control the bootloader from an external device — either a PC or a second Android phone.

The Real "Termux Link" Method: You use one Android device (Device A) with Termux installed, connect it via USB-C to USB-C cable to your target device (Device B), and send ADB/Fastboot commands from Device A to Device B.

This is possible because Termux can install android-tools (adbd and fastbootd) and control another phone over USB, just like a PC.

Run this on the controlling phone’s Termux: The "unlock bootloader using Termux link" is not

adb devices

A prompt will appear on the target phone asking for USB Debugging authorization. Tap "Allow" and check "Always allow from this computer".

Run adb devices again. You should see your device’s serial number and the word "device".

Almost certainly not. Carrier-locked devices usually have the bootloader unlock flag removed entirely.

On the controlling device (the phone that will act as the computer), open Termux and update the package list: Disclaimer: This content is for educational purposes only

pkg update && pkg upgrade
pkg install root-repo
pkg install git nano wget

Now install the essential tools:

pkg install android-tools

This installs ADB and Fastboot for Android. Verify installation:

adb --version
fastboot --version

If you find links claiming to offer a script or tool to unlock the bootloader via Termux, proceed with extreme caution.

Exploit mtk-su (by XDA dev diov) gives temporary root on locked bootloaders for some MediaTek chips (MT67xx, MT8163).
From Termux (with root access gained via mtk-su), you can:

# Only if exploit works and partition writable
su
dd if=/sdcard/unlocked_aboot.img of=/dev/block/platform/mtk-msdc.0/by-name/bootloader

Why it fails now: MediaTek patched aboot write protection in newer bootloaders.
