Script Description: Unlock Bootloader Automation

Overview:

This Python script automates the exploration of all possible combinations of alphanumeric characters to find the unlock code for the bootloader of an Android device. It utilizes the fastboot utility, a command-line tool used in Android development, to interact with the device and attempt to unlock its bootloader.

Key Components:

Character Set: The script employs a character set that includes numbers (0-9), lowercase letters (a-z), and uppercase letters (A-Z). This set forms the basis for generating combinations to be tested as potential unlock codes.

Combination Generation: Using the itertools.product function, the script generates combinations of characters of varying lengths within a specified range. It systematically explores these combinations in an attempt to discover the correct unlock code.

Progress Monitoring: The script features a progress bar that dynamically updates, providing real-time feedback on the current combination being tested and the overall progress in the search for the unlock code.

Optimizations for Speed: Several optimizations, including the use of a set to track tried combinations and periodic progress bar updates, aim to enhance the script's speed and efficiency.

Unlock Attempt: For each generated combination, the script checks whether the device's bootloader allows unlocking. If allowed, it utilizes the fastboot utility to attempt unlocking with the current combination. If successful, the script prints the discovered unlock code and saves it.

Execution:

To execute the script, the user needs to have a connected Android device in fastboot mode and the fastboot utility installed. The script explores all possible combinations systematically, and its runtime may vary based on the length of the combinations and the device's unlockability.

Note:

Unlocking the bootloader is a crucial step in Android development but should be performed with caution. It often involves erasing the device's data, and unauthorized unlocking may void the device's warranty. Users should refer to the device manufacturer's guidelines and understand the implications before attempting such actions.

This script is essentially a tool for automating the exploration of potential unlock codes, demonstrating a common practice in Android device development. Users should exercise caution and adhere to ethical considerations when using such scripts.

Requirements

• Linux or windows operating system
• Fastboot and adb installed
• USB debugging enabled on your device
• OEM unlock enabled on your device

Usage

1. Connect your device to your computer via USB cable
2. Run chmod +x Bruteforce to make the script executable
3. Run ./Bruteforce to start the bruteforce process
4. The script uses a combination of numbers (0-9) and lowercase letters (a-f) in the unlock code, with a range of 0-255. You can further customize the alphabet array and the min_code, max_code, and step variables to suit your needs.
5. The script will save the current value in a persistent file every time it exits, so you can resume from where you left off
6. If the script finds your unlock code, it will display it on the screen and exit

Instructions for using the Python version of the script:

Connect your device to your computer using a USB cable.
Enable USB debugging on your device by going to Settings > Developer options > USB debugging.
Open a terminal or command prompt and navigate to the directory where the script is saved.
Run the script by executing the command python3 script_name.py.
When prompted, select your device from the list of connected devices.
Wait for the script to finish.
Once the script finishes, check the .dat file associated with your device for the unlock code.

Note that the script assumes that you have the fastboot tool installed on your system. If you don't have it installed, you can install it using the following command:

For Ubuntu: sudo apt-get install android-tools-adb
For macOS: brew install android-platform-tools
For Windows: Download and install the Android SDK Platform Tools package from the official Android developer website.

Also, note that the script has not been extensively tested and may require additional modifications depending on your specific device and environment. Use at your own risk and make sure to backup any important data before running the script.

The modifications I made include:

Adding uppercase letters and numbers to the alphabet array
Updating the range of the min_code, max_code, and index variables to include the entire alphabet array
Updating the value of value to include the next character in the alphabet array instead of incrementing the ASCII value of the current character.

Keep in mind that the length of the alphabet array and the max_code value should be adjusted if you want to use more characters or a longer unlock code.

Please note that this example is specific to numbers and lowercase letters. You can modify the alphabet array to include uppercase letters, symbols, or other characters
