- Booting your device into Fastboot mode. This usually involves holding a specific button combination (e.g., Power + Volume Down) while the device is off.
- Connecting your device to your computer via USB.
- Verifying the connection by typing
fastboot devices. If your device is recognized, its serial number will appear. - Executing the flashing script. This script will contain commands to flash each partition (boot, system, recovery, etc.). You can usually run it directly (e.g.,
flash-all.baton Windows orflash-all.shon Linux/macOS). Alternatively, you can flash individual partitions using commands likefastboot flash boot boot.img,fastboot flash system system.img, etc. - Once all partitions are flashed, reboot your device using
fastboot reboot.
It’s crucial to use the exact commands and firmware files provided for your specific device model.
Method 3: Installing Custom ROMs and Stock ROMs via Custom Recovery (e.g., TWRP)
This method is the most versatile and is essential for installing custom ROMs, but it can also be used to flash stock firmware if the manufacturer doesn’t provide dedicated flashing tools. A custom recovery like TWRP (Team Win Recovery Project) replaces the stock recovery and offers advanced features for managing your device’s software.
The process typically involves:
- Unlocking Your Device’s Bootloader: This is a prerequisite for installing a custom recovery. As mentioned before, this usually wipes your device.
- Flashing a Custom Recovery (e.g., TWRP): This is usually done via Fastboot. You’ll download the TWRP
.imgfile for your device, boot into Fastboot mode, and flash it usingfastboot flash recovery twrp.img. - Downloading the Firmware/Custom ROM: Obtain the desired firmware or custom ROM zip file. Ensure it’s compatible with your device and download any necessary accompanying files (like GApps for custom ROMs).
- Transferring Files to Your Device: Connect your device to your computer and copy the downloaded zip files to your device’s internal storage or an SD card.
- Booting into Custom Recovery: Power off your device and boot into recovery mode by holding the appropriate button combination (often Power + Volume Up).
- Performing a Nandroid Backup (Highly Recommended): Before flashing anything new, it’s wise to create a full backup of your current system using TWRP’s backup feature. This allows you to restore your device to its previous state if something goes wrong.
- Wiping Data (Factory Reset): For a clean installation, it’s generally recommended to wipe the data, cache, and Dalvik/ART cache partitions. In TWRP, this is done through the “Wipe” menu.
- Flashing the Firmware/Custom ROM: In TWRP, go to “Install,” navigate to the location where you saved the zip file, select it, and swipe to confirm the flash.
- Flashing GApps (if applicable): If you are installing a custom ROM that doesn’t include Google Apps, you’ll need to flash a GApps package immediately after flashing the ROM, before rebooting.
- Rebooting Your Device: Once the flashing is complete, select “Reboot System” from the TWRP menu. The first boot after a firmware update can take longer than usual.
This method offers the most flexibility but also carries the highest risk if done incorrectly. Always follow guides specific to your device and the ROM you are installing.
