My iPad is stuck verifying when I try to update to 15.0.2 (iPad Pro 9.7")

We have two iPad pros both cellular models but both have no cellular plan active. IPad A has a SIM card the other, iPad B has an empty sim slot. Both have iPadOS 15.0.0

iPad A was able to OTA update to 15.0.1 with no problem. IPad B got stuck on "verifying" after downloading and we tried everything from rebooting, deleting, and re-downloading the update, but always the same result: stuck verifying.

after deleting the update file in Settings>iPad Storage and hard rebooting, we took the SIM card out of iPad A (any correct size shape SIM card will do, working or not working) and putting in iPad B, we repeated the update steps and it worked as it should. Clearly, there is a bug in all this somewhere, but for now, we are updated and we didn't have to resort to PC to do it.

I had the same "Verifying Update" hanging issue with my iPad Pro 2nd Gen 12.9" and all I had to do to resolve was remove the SIM card holder/tray (no actual SIM card was needed). Once the SIM card tray was remove the installation almost immediately continued.

Thanks for everyone's comments that led me to this unusual solution :-)

If you find that you can’t install on an iPad 10.5 Pro, try taking out the SIM Card Tray, I also could not install iPadOS 15.0.1 & 15.0.2. I saw a comment here that suggested putting in a blank SIM, however it appears that it is not the SIM Card - just the SIM Tray. Once it is opened, the 15.0.1 & 15.0.2 will then install.

We were able to repeat this procedure again updating to 15.0.2 as well. The iPad without the SIM card would not update wirelessly over the air until we inserted a SIM card into the slot. Old iPad Pro 9.7 in models.

This works!! After many attempts, no joy, even using completely updated Mac to try and undertake the upgrade which failed. Was losing hope and because we live in country Western Australia, a trip to an Apple Store is a big ask! Something so illogical!! I had an old sim lying around and once I'd put that in my iPad Pro 2nd generation, the 'verifying update' was 15 seconds, the iPad restarted and upgraded fine all under 15 minutes.

I had the same iPad Pro 9.7 and and the same update problems. Tried all methods suggested online and through Apple Support App. The first time I went to Best Buy (Apple authorized) without an appointment and they did the update. The second time for 15.0.1 I made a Best Buy appointment (as Apple support suggested) and was charged $40 for the update. Then a few weeks later 15.0.2 came out! Same problems as others trying to update. So I let it go and left the red 1 stay on the settings app. I recently signed up for an esim T-Mobile prepaid cellular plan through my iPad Pro 9.7.

This Saturday morning I decided to try again to update to 15.0.2. IPad charged 100%. Plugged in. Wi-Fi + T-Mobile cellular on. I think this combo did the trick. The download was quick unlike before. The install a little longer but Iwas happy it reached the Apple screen with the. Bar moving. Slowly but moving. And finally my iPad Pro 9.7. Was successfully updated to 15.0.2. In the future I will wait a couple of weeks or longer before trying an update. I will have both Wi-Fi + Cellular turned on. And do it around 630 a. m. Knock on wood.

I have exactly the same issue with 15.0.1 which wouldn't work, and then 15.0.2. I tried deleting the update from the ipad, and restarting. I also tried the SIM tray out which didn't work (and I expect is a red herring). I don't have a spare SIM to use. My iPad Pro is 10.5 inch.

About > Software Update says the update is 443Mb, but when downloaded it is 640Mb.

I am trying now via the iTunes on PC.

Odd that iTunes (after an update itself) says it is downloading 5.01Gb iPadOS 15 update (when my iPad is on that OS).

First time around it failed with an Error 4000. PC and iPad rebooted and going through it again...

Second time Error 4000 again. (It says "extracting software...") and preparing to update, backing up (again!). Preparing ipad for update (again).

3rd time error 4000. None of the troubleshooting steps work.

So no idea what to do now.

Like everyone else my iPad was finally able to update (after spinning out for days) when I ejected the SIM card holder. I put an old SIM card in but I think it started updating as soon as I opened the slot. This is ridiculously goofy and makes no sense. Get it together Apple!

WOW! This solution worked first try. Empty SIM card tray, just had to remove and reinsert it. This is crazy. I had been dealing with this for days. All of the other blog posts pointed to resetting network settings. Nothing had worked until this fixed it. Thank you!

So weird. Thank you for this post. I had the same problem. Paper clip fixed it in 2 seconds. 2 seconds after taking out the SIM tray, the screen went black, now it is booting and installing the update.

As soon as I removed the SIM tray, the "Verifying" message disappeared and it started updating.

I tried several other avenues, disabling auto-lock & passcode, attempted to update from a computer and lastly erasing the iPad entirely and trying to update with that fresh iOS 15 install. Nothing worked except ejecting the SIM tray.

Hello,

Thank you very much! Unbelievable, I've been trying everything I could to install the update for days, I even connected my iPad via hotspot: nothing!

I hadn't thought of such a solution, in fact, as soon as I removed the sim card holder (I use my iPad Cellular without a sim at the moment), the installation immediately started. Thanks for your helpful suggestion! Have a nice day. :-)

confirmed user kytdluyfljyfliygöiyfliy solution with iPad Pro 9.7-inch WiFi, Cellular (empty SIM tray)

iPadOS update stuck with "Verifying Update" status message

stays dysfunctional:

power-off

remove SIM tray

power-on

hit install for update

works with solution 'workaround':

power-off

install working SIM insert tray

power-on

hit install for update

done

Note: After another power cycle to remove SIM to return to cell phone, SIM/phone had to be reconfigured by carrier

As suggested above, inserting the SIM card from my iPhone into my iPad temporarily fixed the failed update problem. I spent over a week trying to figure out why the iPad update kept failing and was at a loss. Apple should never have such a simple problem, and when they do, it should be fixed quickly.
