Unlock Bootloader Using Termux Link -
Note: Termux cannot run fastboot commands while the phone is in Fastboot mode unless you have specific kernel support or are using a secondary device. Standard Android kernels do not allow userspace programs (like Termux) to communicate with the bootloader hardware.
You must use a PC for this final step.
However, if you have a specific setup where Termux can access fastboot interfaces (rare and requires root/custom kernel), the command would be:
fastboot flashing unlock
Or for older devices:
fastboot oem unlock
Using a PC (Recommended Method):
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.
Before attempting any method, ensure you have:
If you are searching for a way to unlock your Android bootloader using a "Termux link" or a simple script, it is vital to understand the technical reality before you proceed. unlock bootloader using termux link
The short answer is: You cannot unlock a bootloader using Termux alone.
While Termux is a powerful terminal emulator that provides a Linux environment on Android, it operates within the user space of the operating system. It does not have the deep system-level permissions required to write to the bootloader partition or communicate with the device's bootloader mode (Fastboot).
Here is a breakdown of why this is the case, the risks involved with "link" scripts, and the actual method you should use.
If a website gives you a link that claims to unlock via Termux by just clicking it, it is likely: Note: Termux cannot run fastboot commands while the
Legit developers never ask you to run random curl | bash commands from Termux for bootloader unlocking.
Disclaimer: Unlocking the bootloader will wipe all data on your device. Proceed at your own risk. Not all devices allow unlocking (e.g., some carrier-locked phones or specific brands like Huawei).
No. The fastboot package in Termux can parse commands but cannot send them over USB because Android lacks the necessary ioctl permissions.
If you have an OTG cable and a second Android device: Or for older devices: fastboot oem unlock
This works — but Device B is acting as a PC. The locked device still needs hardware buttons to confirm. This is the only legitimate "Termux link" method.
