This also happened to me too. I had it on my main iPad 7th gen and I had to get stuck on my iMac till Christmas! I was on that software version when it was released. A few days later on a Sunday morning, I was checking my Twitter till all of a sudden, my iPad randomly restarted! I have this experience this issue before and it successfully lets me restore it. I was just downgrading to a version of iOS 13 when I didn't like the way how iOS 14 didn't have bedtime mode, I only selected Update Software instead of Restore. Now however, when I had this issue again on iOS 14 Beta 2, it's different. My iPad was stuck on the Apple logo and I couldn't get it off. It restarted with the Apple logo and some flashing green and red lines. It sometimes display a red screen for a second then it restarts. I tried restoring it in iTunes and I had the same error as 4013. I had random errors from 4013, which I forgotten. I tried doing this on a another computer but still 4013. I tried restoring it using the DFU mode but it's still 4013. Though, after a few whole times, It successfully gave me a "Welcome to your new iPad" screen which I thought it worked, till it restarted again. WITH THE SAME ISSUE! I gave up and decided to take it to the Apple Store. But, when this problem happened during the day, all Apple Stores were closed. So I had to be stuck on my iMac for a while. Now, In September or November, my Apple Store is open. I contacted my brother to schedule an appointment to the Genius Bar and try to find a solution to fix my iPad. I was messaging my brother and what he told me that the Genius Bar told my brother that the iPad is bent and I actually broke the inside of it. Which that's what I believed, because my iPad was a bit bent but it's in fine condition. Now, when I saw this forum, I was glad that I wasn't the only one with this same problem. For now, I still tried restoring my iPad, but now it won't let me. Because it's now stuck on "Waiting for iPad" and It won't let me go through that screen. I still have my previous iPad today and I don't know how to restore it. It's dead, and it will probably be stuck on that Apple logo, forever, and forever. I'll try again tomorrow and see if I can find solutions to my problem.
