Firmware Update for Zenfone 4, 5, 6 - If you're new to using Zenfone, or if you're looking to update to the latest firmware version, today I'll show you how to update your Zenfone to the latest international version in the simplest and quickest way possible.

Updating firmware on Zenfone devices (Zenfone 4, Zenfone 5, Zenfone 6) is incredibly simple, perhaps the easiest process ever, and can be done directly on your device without needing a computer. Below, I'll guide you through the steps to update the firmware for all three Zenfone models.

How to Upgrade ROM(Firmware) for Zenfone:

Step 1: Power off your device, enter Recovery Mode by pressing and holding the Power + Volume Up buttons simultaneously until the device enters Droidboot Menu > select Factory Reset to restore the device to its factory state.

Step 2: Download the international ROM version from the provided link above. International Firmware versions for the Vietnam market will have the code WW, while other codes will follow similar update procedures.

Proceed to extract the downloaded firmware. For example, for the latest Zenfone 5 firmware, it will be UL_ASUS_T00F_WW_1_17_40_16.zip. After extraction, you will get a file named UL-ASUS_T00F-WW-1.17.40.16-user.zip. Copy this .zip file and move to Step 3.

Step 3: Connect your Zenfone device to your computer via USB cable, transfer the extracted *.zip file from Step 2 to the internal storage.

Step 4: Disconnect the USB cable. Your device will automatically detect the new update. Select the notification prompt and wait for about 2-3 minutes for the firmware update to proceed. Afterward, your device will restart, and the update process will be complete.
