Just bought a brand new iPad Pro 10.9 in and it freezes updating to 17.4.1. I have tried reinstalling multiple times with the same problem

Synchronise? Your description suggests that your are instead attempting to transfer data and settings from the iPhone to iPad during initial setup.

You can only transfer or restore data to a target device that has the same or later version of iPadOS as the source. As such, if the iPhone has a newer version of iOS than the target iPad version of iPadOS, then transfer or restore process will stall or fail.

To resolve this situation, if applicable, you will need to initially abandon the transfer process - and then setup the new iPad with your AppleID from the "hello" page without attempting to transfer data and settings. After initial setup has been completed - and the new iPad has itself been successfully updated to iPadOS 17.4.1 - you can then perform the transfer.

Note also that you'll not be able to update the iPad using the iPhone's WiFi hotspot connection; the iPad will need a regular WiFi connection.

Restart the iPad:

Force restart iPad (models with Face ID or with Touch ID in the top button)

If your iPad doesn’t have the Home button, do the following:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

Force restart iPad (models with the Home button)

Press and hold the top button and the Home button at the same time. When the Apple logo appears, release both buttons.

After restarting the iPad, complete initial setup of your new iPad; do not attempt to transfer data and settings from the iPhone:

Ensure that the new iPad has been updated to the most recent version of iPadOS:

When your new iPad has been updated, should you choose to do so, you can transfer your data from the iPhone to iPad*:

(*) Having completed initial setup and update of your new iPad - if intending to use QuickStart, having updated the iPad, it must now be reset:

Settings > General > Transfer or Reset iPad > Erase All Content & Settings

In performing the reset, you can begin setup of your new iPad again, bringing the two iPads close together so that QuickStart (if this is your chosen method) can perform the transfer. Apps that are both compatible and remain available will be automatically installed from the App Store at conclusion of the transfer.

If the donor iPhone (or iPad), from which you are transferring your data precedes iOS12.4, QuickStart will not be available.

“Transfer” is rather a misnomer. In reality, your data and setup is merely cloned to the new device. Nothing is moved or removed from the original device.

An alternative is to restore either an iCloud or iTunes backup to the new device:

Apps are not directly transferred between devices. For Apps, the transfer process creates a record of the Apps that are installed on the donor iPad - and it is this record of installed Apps that is transferred to the target (new) device. For Apps that are still available for download from the App Store, the corresponding Apps are automatically downloaded and installed from the App Store.
