Hopefully, this will help you to work out the best solution to upgrade your iPhone, iPad, or iPod device to a more recent version.

The Different Options to Update your Device Without iCloud

Have you ever wondered about the different options to update your device without iCloud? If so, then we’ve summarized two common options as follows: the custom IPSW method and the StarzSoft KeyPass methods, both of which allow you to update your device without iCloud activation.

IPSW Without iCloud Activation Download

First of all, let’s consider the IPSW method for unlocking your iPhone, iPad, or iPod device without iCloud activation. The IPSW method is easiest for Windows users; however, it’s also possible for Mac users.

With that being said, the IPSW without iCloud activation download method is exceptionally difficult compared to other options – so, if tech isn’t your forte, you may want to consider a simpler method such as StarzSoft KeyPass (as we’ve outlined below).

1. IPSW for Windows Users

How can you use the IPSW method to update your iOS device without iCloud activation?

Step1: Start by downloading the IPSW onto your Windows computer.

Step2: Then, head to your download folders and rename the extension as .zip, which will allow you to extract the files.

Step3: Open the extracted files folder, and select all of the files with the extension .dmg.

Step4: Then, use a decrypting key to decrypt the files; you can source these from destinations such as The Phone Wiki.

Step5: Now, copy the largest file onto your desktop and open the file before heading to the Applications folder; here, you should see a “” file. Delete this file, and then save the decrypted file.

Step6: Finally, all that’s left to do is to re-encrypt the file using the encryption key you used previously and similarly rename the final to the original.

Step7: Then, return the file to a zip format and replace the original download.

At this point, you’ve got a custom IPSW that will allow you to bypass iCloud activation locks on your device.

2. IPSW for Mac Users

As we’ve already mentioned, things are a little more tricky for Macbook users. However, you can still create a custom IPSW to update your device, if necessary. Nevertheless, it’s worth noting that this method is slightly more complicated than even the Windows version.

Step1: First, download the IPSW as before onto your Mac, and then alter the extension to .ZIP. Extract the .ZIP file and, as before, find the largest .DMG file. This should be moved to the desktop tab.

Step2: Once again, this file will be encrypted; so, you’ll want to use a de-encrypting tool to gain access to it. We recommend you use the encryption codes from the iPhone Wiki for this step again. There’s also an inbuilt tool on your Macbook that can also allow you to unencrypt the file; this is called iDecrypt, and when you run the tool, you’ll be able to gain access to the encrypted file.

Step3: Once you have unencrypted the file using iDecrypt, you’ll then want to head to the decrypted file itself.

Step4: Find Applications and move the file to the trash, before Ejecting the file (using the right-click button) to save it.

Step5: At this point, we’re largely back to the same instructions as before. Simply delete the original version and rename the custom version you have just made with the same name, and then move this back to the extracted folder.

Step6: Finally, recompress the whole folder to return it to a custom IPSW form.

Notice:The IPSW Method Is Incredibly Complicated

There’s no doubting that the IPSW updating method is incredibly complicated – and, with this in mind, you may want to give another option a try instead.

Indeed, unless you’re particularly tech-savvy (and if you are, that’s great), the following instructions will likely seem like they’re written in Arabic! Fortunately, the custom IPSW method isn’t the only option for how to unlock your device, and this could be worth considering as a result.

StarzSoft KeyPass – The Simpler Method and Better for Newer Devices

If you have a newer model of iPhone, iPad, or iPod device, then you may be less likely to succeed using the custom IPSW without iCloud activation download option.

With this in mind, you may want to consider an alternative tool such as StarzSoft KeyPass, which can automatically bypass iCloud activation locks on your device while simultaneously updating your device to the latest version.
