Download and Install iPadOS 15 – iPadOS 15.4 Directly on Your iPad

Before you commence the iPadOS 15 – iPadOS 15.4 download, connect your iPad to a power source so that the battery doesn’t drain during the update process. Depending on your internet connection and how Apple’s servers handle the load, it could take anywhere from a few minutes to an hour for the update to download and install. You may also want to connect your iPhone to your local Wi-Fi network, so you don’t get charged for downloading the update over a cellular connection.

Step 1: Once your iPad is plugged in and connected via Wi-Fi, open the Settings app, and tap on General > Software Update. iPadOS will automatically check for available updates and inform you that the iPadOS 15 – iPadOS 15.4 software update is available.

Step 2: You will be presented with a screen that details all the new features and improvements in iPadOS 15 – iPadOS 15.4. Tap Download and Install to start the update on your iPad.

If you are tired of waiting for the download to finish (it could take a while), we suggest you handle your to-do list in the meanwhile. Your iPad will continue to download the update and send you a notification when the update process requires user input to proceed.  When you’re notified, go back to Settings > General > Software Update and tap Install Now to install iPadOS 15 – iPadOS 15.4 on your device.

Download and Install iPadOS 15 – iPadOS 15.4 on iPad using Computer

If you’re not getting the iPadOS 15 – iPadOS 15.4 software update via OTA as mentioned above, you can install it manually by downloading the iPadOS 15 – iPadOS 15.4 firmware file (IPSW) from here. Then use iTunes or Finder to update your iPad device manually. You may also need to install the update using iTunes if you don’t have enough storage space on your device for the OTA update.

On a Mac with macOS Catalina 10.15, open Finder. On a Mac with macOS Mojave 10.14 or earlier, or on a PC, open iTunes. If you are using iTunes, then just ensure that you’re using the latest version.

Step 1: Connect your iPhone to your computer using a USB cable. Wait for iTunes to open and detect your device.

Step 2: If you are using iTunes, click on the device button beside the iTunes Store button in the top right corner of iTunes. If you’re using Finder, check on your device under Locations.

Step 3: Click on the Check for Update button. If the iPadOS 15 – iPadOS 15.4 update is available, it will be automatically downloaded and installed.

Step 4: You will get a popup message informing you the new update is available. Click the Download and Update button. At times it takes some time for the software update to be rolled out on all the servers, so if it says the older iPadOS version is still the latest version, then download the appropriate firmware file using download links provided in step 5.

Step 5: Download the iPadOS 15 – iPadOS 15.4 ISPW file for your iPhone from below.

Step 6: You will get a popup message informing you that iTunes will update your device to iPadOS 15 – iPadOS 15.4 and verify with Apple. Click on the Update button.

Step 7: The release notes for iPadOS 15 – iPadOS 15.4 will then be displayed. Click on the Next button. Then click on the Agree button for the terms and conditions when prompted.

Step 8: iTunes will now download the firmware file (which could take a long time, again, depending on your internet connection. The file can be as big as 2.0 GB). After being downloaded, the file will be processed and extracted. iTunes will then prepare the device for the software update, and install the said update automatically.

Step 9: Do not disconnect your device until the update has finished. It can take a few minutes. Your device will be updated to iPadOS 15 – iPadOS 15.4 and will reboot once during the process. You’ll see the familiar Hello screen after a successful update. Follow the on-screen instructions to start using your iPad again, now with its new features.
