How to Use Termux Root Recovery Tool

Now that you are aware of all the features of Termux-Root-Recovery-Tool, let’s make you aware of the steps to put this tool to the test. But before that, please take a complete device backup. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

The primary device is the one on which the ROM, Recovery, etc, will be installed. Whereas, the secondary device is the one we will be carrying out the steps, such as installing Termux [this will act as our “PC”].

1. To begin with, pick up a secondary Android device.
2. Then connect that device to your primary device using an OTG.
3. Now, install Termux and Termux API apps on your secondary device. You might have to turn off Play Protect before installing Termux API.
4. Now launch Termux and execute the following four commands: SETUP TERMUX: yes | pkg update && upgrade termux-setup-storage pkg install termux-api yes | pkg install git INSTALL TERMUX-ROOT-RECOVERY-TOOL: git clone https://github.com/Ishu43642/Termux-Root-Recovery-Tool.git cd Termux-Root-Recovery-Tool chmod +x flash.sh && chmod +x flash-stock-rom.sh && chmod +x flashAB.sh && chmod +x gsi-flash.sh INSTALL ADB IN TERMUX: bash installadb.sh RUN TOOL: ./flash.sh
5. As soon as the four commands are executed, the tool will open in Termux.
6. You may now choose the desired option and get going!
7. NOTE: The file that you want to flash should be on your secondary device.
8. For instance, if you want to root your device: first reboot to Fastboot Mode [option 7 or via hardware key combinations] > then flash a custom recovery [option 1] > then reboot to recovery [option 9 via or hardware key combinations] > now flash the Magisk ZIP via the recovery > then boot to the OS.

Unlock Bootloader, Flash Recovery, Custom ROM via Termux-ADB

This is a command-line tool that allows you to execute ADB and Fastboot Commands in Termux. But, as opposed to the generic route, the ADB and Fastboot Commands syntax is slightly different in Termux. Over here, you will have to add ‘termux-‘ before the ‘adb’ and ‘fastboot’ keywords in all the Fastboot Commands.

For example, to boot the device to Fastboot, then instead of ‘adb reboot bootloader’, you’ll have to use ‘termux-adb reboot bootloader’. Likewise, if you want to check the Fastboot connection, then instead of the ‘fastboot devices’ command, you’ll have to use the ‘termux-fastboot devices’ command. So keep this point in mind before proceeding ahead.

The primary device is the one on which the ROM, Recovery, etc, will be installed. Whereas, the secondary device is the one we will be carrying out the steps, such as installing Termux [this will act as our “PC”].

Install Termux Packages

1. Download and install Termux from F-Droid.
2. Likewise, download and install Termux API . You might have to turn off Play Protect before installing Termux API.
3. Now, launch Termux and install its API via: pkg install termux-api
4. Next, install the GIT package via the command: pkg install git
5. Now clone the Git repository via the command: git clone https://github.com/nohajc/termux-adb
6. Then change the working directory to Termux ADB: cd termux-adb/
7. Now install the script via the below command: ./install.sh

How to Unlock Bootloader via Termux

1. Make sure that you have done the setup, as mentioned above.
2. Then enable USB Debugging and OEM Unlocking on your secondary device.
3. Now type in the below command in Termux Tool to boot the device to the Fastboot Mode. termux-adb reboot bootloader If it doesn’t work out, then you may use the hardware key combinations to boot to Fastboot Mode.
4. Then type in the below command to unlock the bootloader: termux-fastboot flashing unlock
5. You’ll now get a prompt, select Unlock the Bootloader via Volume keys and press the Power key to confirm.
6. Your device will undergo a reset and the bootloader will be unlocked.
7. Re-enable USB Debugging and move over to the next step now.

How to Flash a Custom Recovery using Termux

1. Transfer the custom recovery to the secondary device’s Internal Storage. Likewise, rename it to twrp.img.
2. On the other hand, transfer the ROM ZIP file to your primary device [the device where the ROM will be installed].
3. Now type in the below command in Termux Tool to boot the device to the Fastboot Mode. termux-adb reboot bootloader If it doesn’t work out, then you may use the hardware key combinations to boot to Fastboot Mode.
4. Then change the working directory to Internal Storage using the below command: cd /storage/emulated/0
5. If you get the error message: Permission Denied, then first use this command: termux-setup-storage
6. Then, once again,n try changing the directory via the below command, this time you will not get any issues: cd /storage/emulated/0
7. Now, verify if your device has a recovery partition or not . If it has, then you can directly and permanently flash the recovery in the recovery partition. However, if it doesn’t, then we will be temporarily booting your device to recovery first and then making it permanent by flashing the ZIP/IMG or by using the Flash Current TWRP option from the Advanced menu. Here’s the command for both: termux-fastboot flash recovery twrp.img //permanently flash recovery termux-fastboot boot twrp.img //temporary boot to recovery. You may now make the recovery permanent [optional] as explained above.
