I cannot update my iPad 8 to iOS 18 Beta 3

I was trying to update my iPad 8th Generation, but ran into some trouble.

Since my iPad didn’t have enough capacity to install the update directly, I connected it to my MacBook M1 and downloaded the iPad OS 18 IPSW file.

Unfortunately, it didn’t go as planned. I got an error message saying,

"The iPad 'My iPad' could not be restored because the firmware file is not compatible."

Has anyone else faced this issue or found a solution? Any help would be appreciated!

I'm having the exact same issue. The OTA updates don't work well because of limited space. Even when I do clear enough space by offloading apps, the required space goes up and it always tells me I need more.

Tried updating today via IPSW and getting the same error.
