Here is a step-by-step tutorial on how to download and install iOS 14 Beta 1 and iPadOS 14 Beta 1 using PC Windows. You can follow the instructions in this guide to install the official iOS 14 beta 1 on iPhone, iPad, or iPod touch.
Apple announced the latest version of iOS during WWDC 2020 keynote. We have already discussed that installing the iOS 14 and iPadOS 14 beta is just as straightforward without an active OTA update option.
iOS 14 Beta 1 / iPadOS 14 Beta 1:
Beta 1 is available to members of the iOS developer community. The official public beta 1 won’t be available until a later date but there is a workaround to install Public Beta as explained in this guide here.
Moreover, to install iOS 14 developer beta, users need to have access to a Mac computer with macOS Big Sur installed and Xcode 11 program.
This stipulation restricts beta access only to developers having a Mac device. But what about Windows users? iOS users often pose a query: how to install iOS beta using Windows PC or laptop? There is no Xcode or its equivalent software on the Windows platform. Fortunately, there is still some light at the end of the tunnel. It is possible to install iOS 14 and iPadOS 14 through IPSW files using a Windows PC or Laptop.

Install iOS 14 Beta 1 Using PC Windows and Laptop:
Here are the steps you need to perform in order to flash iOS 14 IPSW or iPadOS 14 IPSW file onto your iPhone, iPad, or iPod touch. Make sure your device qualifies as compatible to run the latest iOS version.
Step 1 – Ensure that iCloud and iTunes programs are updated to their most recent versions.
Step 2 – Next, verify that your device’s UDID is listed on the Apple developer portal to confirm its active registration status.
Step 3 – Download the IPSW for your particular device model.
Step 4 – Now get libimobile2019 from GitHub and unzip the master.zip file to extract its content. Extract the content into a separate folder on C: drive.
Step 5 – Connect your iPhone or iPad to your computer.
Step 6 – After that, open the Command Prompt and drag the idevicerestore.exe file from the libimobile2019 library into the prompt window. Once done, add ” -d” to the end (without quotation marks and don’t forget to add space, too).
Step 7 – Follow up by dragging the IPSW file to the same command prompt to complete command with its location. The full command should look like this:
C:\Users\YourUsername\Downloads\libimobile2019\idevicerestore.exe” -d “C:\Users\YourUsername\Downloads\iPhone112iPhone116_13.0_17A5492t_Restore.ipsw
Step 8 – Now hit the enter key and wait for the execution process to complete. Your device will restart multiple times during the process, so don’t panic and be patient.
That’s it. This method essentially updates your iPhone or iPad, not restore it. This should be a relief since no data loss occurs but mileage may vary. Therefore, it is better to backup data before trying the above solution.
