Error messages when updating iPad from iOS 11.4 to iPad OS 14.2
Hello,
I have been trying to update an iPad 6th Generation (Wi-Fi + Cellular) 32GB from iOS 11.4 to iPad OS 14.2 but I am getting lots of error messages. First, I tried updating with iTunes three times and each time I get the error code 4000. The last time, I made sure the iPad did not go to sleep in the middle. Then, I connected to Wi-Fi and tried over the air. The first time, I got the error that the install failed and it couldn't install iPad OS 14.2. I restarted the iPad and tried again, getting the same result. The last time I tried I checked the storage space which has only 10GB in use. I had read online to delete the downloaded update and try again (from the Storage area) but it did not show up in the list of things taking up space on the iPad, even after waiting a while. I am out of ideas and am hoping someone can please help?
Thank you for your time.
