However, many users face confusion when it comes to updating custom ROMs due to the lack of a direct and straightforward approach. If you find yourself uncertain about which method to choose, this guide is here to help. We will walk you through five different methods that you can follow to update your custom ROM. Let’s get started!

Method 1: Via OTA Update to Update Custom ROM

The easiest and most preferred way to update custom ROMs is through OTA (Over-The-Air) updates. Simply go to Settings > System, and download and install any pending update. After restarting your device, it will boot up with the newly installed OS. However, not all custom ROMs support OTA updates. If that’s the case, you can explore the alternative methods below.

Method 2: Via Custom ROM’s Recovery to Update Custom ROM

Many custom ROMs now come with their own custom recovery, such as Lineage Recovery or Pixel Experience Recovery. You can use the custom recovery to update your ROM. Here’s how:

  1. Download the ROM update file and transfer it to the platform tools folder on your device. Rename it to rom.zip.
  2. Open the platform-tools folder on your device, type CMD in the address bar, and press Enter to launch the Command Prompt.
  3. In the Command Prompt window, enter the following command to boot your device into Recovery mode: adb reboot recovery.
  4. In Recovery mode, navigate to Apply Update > Apply from ADB. Your device will enter ADB Sideload Mode.
  5. To flash the updated ROM file, enter the following command in the Command Prompt: adb sideload update.zip.
  6. Once the flashing process is complete, select Reboot System Now to restart your device with the updated OS.

Method 3: Via Fastboot Command to Update Custom ROM

If your ROM update file is in the form of a flashable ZIP, you can use the Fastboot command to update your custom ROM. Follow these steps:

  1. Ensure that you have the necessary USB drivers installed on your computer for your Android device.
  2. Power off your device and boot it into Fastboot mode. The method to enter Fastboot mode varies depending on the device, so you may need to search for specific instructions for your device model.
  3. Connect your device to the computer using a USB cable.
  4. Open a Command Prompt or Terminal window on your computer and navigate to the folder where you have the Fastboot tool installed.
  5. Verify that your device is recognized by the computer by entering the following command:
    • fastboot devices
      If your device is listed, you’re ready to proceed.
  6. Flash the ROM update file by entering the following command:
    • fastboot update rom.zip
      (replace rom.zip with the actual name of your ROM update file).
  7. Wait for the flashing process to complete.
  8. Once the flashing is done, reboot your device by entering the command: fastboot reboot.

Method 4: Via TWRP Recovery to Update Custom ROM

TWRP (Team Win Recovery Project) is a popular custom recovery that provides a graphical interface for installing custom ROMs and other modifications. If you have TWRP installed on your device, you can use it to update your custom ROM. Here’s how:

  1. Download the ROM update file and transfer it to your device’s internal storage or external SD card.
  2. Power off your device.
  3. Boot your device into TWRP recovery mode. The method to enter recovery mode varies depending on the device, but it usually involves holding specific buttons during the boot process. Search for instructions for your specific device if needed.
  4. In TWRP recovery, select the “Install” option.
  5. Navigate to the location where you transferred the ROM update file and select it.
  6. Swipe the “Swipe to Confirm Flash” button to start the ROM flashing process.
  7. Wait for the flashing process to complete.
  8. Once the flashing is done, select the “Reboot System” option to restart your device with the updated ROM.

Method 5: Via ADB Sideload of TWRP to Update Custom ROM

If you have TWRP recovery installed on your device and prefer using ADB (Android Debug Bridge) for the ROM update, you can follow these steps:

  1. Download the ROM update file to your computer.
  2. Boot your device into TWRP recovery mode.
  3. Connect your device to the computer using a USB cable.
  4. On your computer, open a Command Prompt or Terminal window and navigate to the folder where you have the ADB tool installed.
  5. In the Command Prompt or Terminal window, enter the following command to sideload the ROM update:
    • adb sideload rom.zip
      (replace rom.zip with the actual name of your ROM update file).
  6. Wait for the sideload process to complete.
  7. Once the sideload is done, select the “Reboot System” option in TWRP to restart your device with the updated ROM.
