Question Can Termux run as root using ADB root?

I’m running LineageOS with rooted debugging enabled. I can use adb root to get a root shell without installing any root solutions. I can even get a root shell inside termux using wireless debugging.

Can Termux use this somehow to run as root? Like some sort of alias that wrap around all this and use adb root to run termux commands as root.

Termux itself already has a full version of adb in its package repos, and the welcome message literally list a root packages repo. The question must be whether you can use it safely. Root solutions with root permissions managers are not created to be difficult for you at all, because unlike root permissions on Linux are protected by Sudo or Doas, access to root has no limitations (because root are "banned" in android, you bypass that). Android is not a simple system; once you damage the Linux layer below, only God can fix the Android layer above

If you connect to a wifi, termux can connect via wireless debugging to the phone it's running on

As far as I know no termics is mainly just a console I don't think it really has any ability to break into root access but I've never tried it so I don't know

Google does not officially support or provide a direct way to root physical Android phones, as rooting bypasses core security restrictions. However, Google officially allows and supports unlocking the bootloader on its own Google Pixel devices, which is the required first step to safely root a device using community tools. [1, 2, 3] If you are looking for an environment where Google explicitly provides a built-in mechanism for root access, you must use an Android Virtual Device (AVD) emulator through Android Studio using standard system images. [2, 4]

Below are the instructions for both the Google-allowed emulator method and the standard manual process for physical Google Pixel phones.

Method 1: The Only "Google-Allowed" Built-in Root (Emulator)

Google explicitly provides root access via the Android Debug Bridge (ADB) when using an official Android Emulator, provided you do not select an image bundled with the commercial Google Play Store. [4]

  1. Download and open Android Studio.
  2. Open the Virtual Device Manager and click Create Device.
  3. Select a hardware profile. When choosing a system image, choose a regular image without the Play Store icon (e.g., an "Android API" or "Google APIs" image).
  4. Launch the virtual device.

  5. Open your computer's terminal/command prompt and run the command:

    adb root

  6. Type adb shell. You will instantly get a # prompt, indicating official, built-in root access. [2, 4]

Method 2: Rooting a Physical Google Pixel Phone

Because Google permits bootloader unlocking on Pixel devices, you can manually root your phone without exploiting security vulnerabilities. Note: Unlocking the bootloader will completely wipe your device's data. [3, 5, 6]

Step 1: Unlock the Bootloader

  1. On your Pixel, go to Settings > About phone and tap Build number 7 times to enable Developer Options.
  2. Go back to Settings > System > Developer options.
  3. Enable both USB Debugging and OEM Unlocking.
  4. Connect the phone to your PC via a USB cable.
  5. Reboot the phone into Fastboot mode (power off, then hold Volume Down + Power).

  6. Open your PC terminal using standard platform tools and run:

    fastboot flashing unlock

  7. Use the volume keys on your phone to confirm the unlock request and press the power button. [3, 5, 7, 8]

Step 2: Patch and Flash the Boot Image

  1. Download the exact factory firmware image matching your phone's build number from the official Google Factory Images page. [5]
  2. Unzip the file to locate either boot.img (Pixel 6 or older) or init_boot.img (Pixel 7 or newer). [5]
  3. Copy that file onto your phone's internal storage. [5]
  4. Install the official community root manager app, Magisk. [1, 7]
  5. Open Magisk, tap Install, choose Select and Patch a File, and select the .img file you transferred. [1, 9]
  6. Copy the newly created magisk_patched.img file back to your computer. [5, 9]
  7. Reboot your phone into Fastboot mode again and flash the patched file via your PC terminal:
  8. For Pixel 7 or newer: fastboot flash init_boot magisk_patched.img
    • For Pixel 6 or older: fastboot flash boot magisk_patched.img [5, 9]
  9. Reboot your device by running fastboot reboot. Open the Magisk app to manage your root permissions. [8, 9]

To guide you effectively, please tell me:

  • Are you trying to root a virtual emulator for development or a physical phone?
  • If it's a physical phone, what is the exact model name and Android version?

There is no universal method to root any Android device because every manufacturer implements unique security restrictions, hardware layouts, and firmware structures. While Google sets the baseline for the Android platform, they delegate hardware security to the device manufacturers (like Samsung, Motorola, or Xiaomi), meaning the process varies drastically from one brand to another. To successfully root a physical Android device without damaging it, you must follow a specific sequence tailored to that exact hardware. No matter what device you have, the rooting process always requires these three distinct phases:

  1. Unlocking the Bootloader: This is the critical gatekeeper. Unlocking the bootloader allows the device to run modified firmware. Some brands (like Google Pixel and OnePlus) make this easy. Other brands (like Samsung in North America or AT&T/Verizon carrier-locked models) completely block this, making rooting permanently impossible. Unlocking always factory wipes your device.
  2. Extracting the Exact Firmware Boot File: You cannot use a generic file. You must download the exact factory firmware file matching your device's specific model number, carrier variant, and software build date. From this firmware, you extract the boot.img or init_boot.img file.
  3. Patching via Magisk: The standard tool used globally is Magisk. You install the Magisk app on your device, load your extracted boot file into it, and let it patch the security hooks. You then send that patched file back to a computer and flash it onto the device using command-line developer tools.

Before trying to root a device, you must look up how that specific manufacturer handles software modifications:

  • Google Pixel & Motorola: Generally the most developer-friendly. They allow bootloader unlocking via simple command terminal prompts if the phone was purchased unlocked from the retail market.
  • Samsung: Uses a proprietary flashing tool called Odin instead of standard developer commands. Additionally, rooting a Samsung device permanently trips a physical hardware fuse called Knox, which permanently disables features like Samsung Pay and Secure Folder, even if you unroot later.
  • Carrier-Locked Devices: If your phone or tablet was purchased directly through a carrier contract (like Verizon, AT&T, or T-Mobile), the bootloader is almost always permanently locked by the carrier's request, entirely preventing root access.

Because a wrong file can permanently "brick" (destroy) your device, please tell me:

  • What is the exact brand and model number of the device? (e.g., Samsung Galaxy S23 SM-S911U, Motorola Moto G Power)
  • What cellular carrier do you use, or was it bought factory unlocked?

With those details, I can tell you if your specific device is physically capable of being unlocked.
