iPad frozen due to iCloud request

First, thanks for trying to help me. My iPad does have the box that has "Cancel and Okay" so, as requested, I held down the power button and turned it off. After I brought it back up again, the box with Cancel and Okay was still front and center. As advised, I went into my iCloud account via my laptop, and I clicked on the Find my iPhone. I had a choice of selecting other devices or my iPad. I selected my iPad. iCloud indicated that my iPad was offline. I could select "Remove it from my account", but before I do, I have 2 questions: (1) How will my iPad recognize my iCloud update if my iPad is offline? (Since my iPad is frozen, I can't bring it online). and (2) if I do select "Remove....." does that mean I lose the Find my iPad capability? Again, thank you for your time.

No fix yet but here is what I have tried. So that I had a fresh start, I started by pressing holding the power and home buttons at the same time until I saw the Apple logo. When restarting, I quickly entered my passcode on the front screen. It accepted my passcode and it presented a screen with my folders. The “Sign in to iCloud” box was in the center of the screen. Since the box was still there and it freezes the screen, there was no time to sign in to W-Fi.

Via my laptop (a PC), I logged into iCloud with my Apple ID (my email address) and my Apple password. I remove “Find my phone” from the iCloud. iCloud advised me that I have no devices. True. It also said “(my name) is linked to your Apple ID. Removing this iPad will allow it to be activated and used by another person.” I figured that I could re-associate to Find My Phone to the iPad when I get it back online again. I hated to do it but I am very interested in getting this problem resolved.

I do not have any music or books from iTunes, and I am willing to re-purchase all of the apps from the Apple Store again. When I get wi-fi, I can reload all of my photos from my PC.

As mentioned earlier, my iPad is offline and it cannot connect to a wi-fi as it is frozen. Would it be reasonable to re-initialize my iPad? Will re-initializing the iPad give me the ability to have my Wi-Fi again? If you do recommend re-initializing (offline), how do I do that? Again, I appreciate the support.

Here is where I am with this now:

Step 1 - I successfully entered my passcode on my iPad and the iPad screen changed to the 2^nd screen which has the “Sign in to iCloud” box in the center of the screen.

Step 2 - I connected my iPad to my PC. ITunes came up and asked if I wanted to allow my computer to access the iPad. I selected yes/OK. After a pause, iTunes came back with “To allow access, please respond to your iPad.” I can’t respond to my iPad due the “Sign in to iCloud” box.

I experimented anyway and selected the iTunes File>Devices>. All of the selections are ghosted thus I am not able to select.

I fooled around with iTunes diagnostics and I passed the

Network connectivity test

Device Connectivity Test - Ports - No iPod touch, iPad or iPhone found. (note: the PC port was active as I heard the port sound when I engage and disengage)

Also, I selected “help” and I went through the steps and confirmed that the program called Apple Mobile Devices Support was present.

Device Synch tests - No iPod touch, iPad or iPhone found

Sigh, I have made an Apple appointment for Tuesday.

Thank you so much for taking the time with me. You are really appreciated.
