You have posted into an Apple product user to user technical support community.
We are all, largely, just Apple product customers/users, just like you.
No one here can help you with this issue.
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
Product Feedback - Apple
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 suggest contacting/reaching out to Apple Product support and services.
Tap on the first link below and scroll down some to get to the Apple Product Support section and phone numbers for your location/region.
Contact - How to Contact Us - Apple
OR
Contact Apple for support and service - Apple Support
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 level Apple customer support employees to see if they can come up with other possible advice/solutions to this iPad boot loop issue, but I make no guarantees, whatsoever.
If need be, you can have your iPad issues escalated all the way up the chain to Apple engineering level customer phone support.
Even if no acceptable resolution, Apple, AT LEAST, logs all support calls and issues.
Best of Luck to You!
