If you’re looking to update the firmware on your ZTE Z730 smartphone, there’s an easy way to do it using just an SD card. Updating your firmware can improve the performance and functionality of your device, so it’s a good idea to keep it up-to-date. Here’s how to update your ZTE Z730 firmware with a simple SD card download.

Step 1: Download the Firmware

The first step in updating your firmware is to download the latest version from the ZTE website. Make sure you download the correct firmware for your specific model and carrier. Once you’ve downloaded the firmware file, save it to your computer.

Step 2: Format Your SD Card

You’ll need an SD card to transfer the firmware to your ZTE Z730. Before you can use the SD card, you’ll need to format it. Insert the SD card into a card reader connected to your computer. Open File Explorer (Windows) or Finder (Mac), locate the SD card, right-click on it, and select “Format”. Choose FAT32 as the file system format and click “Start” to begin formatting the SD card.

Step 3: Transfer the Firmware to the SD Card

Once the SD card is formatted, copy the firmware file you downloaded in Step 1 to the root directory of the SD card. This means that the firmware file should be saved directly to the SD card, not inside any folders.

Step 4: Insert the SD Card into Your ZTE Z730

Now it’s time to insert the SD card into your ZTE Z730. Power off your device, remove the back cover, and then insert the SD card into the slot. Make sure the card is properly seated and then replace the back cover.

Step 5: Boot Your Device into Recovery Mode

To update your firmware, you’ll need to boot your ZTE Z730 into recovery mode. To do this, hold down the Volume Up and Power buttons at the same time until the ZTE logo appears. Release the Power button but continue holding the Volume Up button until the Android System Recovery screen appears.

Step 6: Update Your Firmware

Once you’re in recovery mode, use the volume buttons to navigate to “apply update from external storage” and press the Power button to select it. Next, navigate to the firmware file on your SD card (it should be named something like “update.zip”) and select it with the Power button. The firmware update process will begin, which may take several minutes. When it’s complete, select “reboot system now” to restart your device.


Updating your ZTE Z730 firmware using an SD card is a simple and effective way to improve the performance and functionality of your device. Just follow these easy steps and you’ll have the latest firmware update installed in no time.
