Identifying the correct firmware for your specific Android device model is a critical step in the downgrading process. Using the wrong firmware can lead to irreversible damage, rendering your device unusable.
To find the appropriate firmware, you will need the following information:
- Device Manufacturer: (e.g., Samsung, Google, Xiaomi)
- Device Model Number: This can usually be found in the “About Phone” section of your device’s settings.
- Android Version: The desired older Android version you wish to install.
- Region/Carrier: Firmware is often specific to a geographic region or carrier.
Reliable sources for firmware include:
- Manufacturer’s Website: Often provides official firmware downloads.
- Reputable Firmware Databases: Such as SamMobile (for Samsung devices) or similar sites specific to your device’s manufacturer.
Verify the MD5 or SHA checksum of the downloaded firmware to ensure its integrity and authenticity. This will help prevent installing a corrupted or malicious file.
Using the Appropriate Tools: ADB and Fastboot
ADB (Android Debug Bridge) and Fastboot are essential command-line tools provided by Google that facilitate communication between your computer and your Android device during the downgrading process.
ADB allows you to send commands to an Android device while it’s running, enabling tasks such as installing and debugging apps, accessing a shell, and pushing or pulling files. It is crucial for preparing your device before flashing.
Fastboot, on the other hand, is a protocol used for flashing partitions on your Android device while it is in bootloader mode. This is the primary tool used to actually install the older Android firmware. Ensure you have the latest version of ADB and Fastboot installed on your computer and that the drivers for your specific device are correctly configured. Incorrect drivers can prevent your computer from communicating with your device.
To verify that ADB and Fastboot are correctly set up, connect your device to your computer via USB and run the command “adb devices” in your command prompt or terminal. If your device is listed, ADB is working. Similarly, boot your device into Fastboot mode (usually by holding specific key combinations during startup, specific to your device model) and run the command “fastboot devices”. If your device is listed, Fastboot is ready to use.
Step-by-Step Guide: Flashing the Older Android Version
Flashing your Android device with an older version requires meticulous attention to detail. Ensure your device is adequately charged (at least 50%) to prevent interruption during the process.
Step 1: Boot into Fastboot Mode. This is typically achieved by pressing a combination of buttons (e.g., Power + Volume Down) while powering on. Consult your device’s manual for specific instructions.
Step 2: Connect to Your Computer. Using a USB cable, connect your device to your computer. Ensure ADB and Fastboot drivers are correctly installed and recognized.
Step 3: Open Command Prompt/Terminal. Navigate to the directory where you have stored the firmware files.
Step 4: Execute the Flash Command. The exact command varies depending on the firmware type, but commonly involves using the fastboot flash command followed by the partition name and the corresponding firmware file (e.g., fastboot flash system system.img). Flash each required partition individually. Be very careful to flash the correct files to the correct partitions.
Step 5: Reboot Your Device. After flashing all necessary partitions, use the command fastboot reboot to restart your device. The first boot may take longer than usual.
Disclaimer: Incorrect flashing can brick your device. Proceed with extreme caution.
