iPad Pro 10.5 on reboot loop after updated to IOS 13.5.

Sorry to learn that your iPad has contracted this constant boot/re-boot loop issue after upgrading/updated to iPadOS 13.4.1.

This seems to be a growing and recurring issue with many iPads that have been updating to iPadOS 13.4.1

Unfortunately, Apple, currently, has NO fix or solution to this issue, to date!

Other users with this issue, that have actually called into Apple support about this issue, reported were only being offered in-warranty/expensive, out-of-warranty device replacement option, in lieu of Apple support not having an actual device fix or solution for what Apple support is diagnosing as some sort of internal hardware/software failure/fault with no recovery.

Sorry.

You are free and welcome to submit feedback about this issue to Apple.

This is only one of the few ways to directly contact Apple about ANY product issues.

iPad Feedback

http://www.apple.com/feedback/ipad.html

You can post multiple feedback on this iPadOS/iPad boot loop issue as many times as you like to help get Apple's attention on this issue

Cognizant Apple employees read ALL feedback generated from all of the various feedback pages and transfers the data to the proper and responsible Apple teams and personnel, but NO Apple employees will ever respond with any type of direct, individual replies from the feedback you post.

The more users that post product feedback about any product issue, the faster Apple, in California, is made aware and starts working on a fix/solution for a future software update.

If no one posts feedback to Apple, Apple will have NO clue that there are any types of issues with their hardware or software products!

Also, I STRONGLY suggest contacting/reaching out to Apple Product support and services.

If you need to, if initial 1st tier Apple customer support is of no help to you, you can calmly ask to have this issue escalated up to more responsible, senior Apple customer support employees to see if they can come up with a more amiable/amenable solution to this iPad boot loop issue, but I make no guarantees, whatsoever.

Even if no acceptable resolution, Apple, at least, logs all support calls and issues.

Sorry & Best of Luck to You!
