Unable to install iPadOS 15.0.1 on iPad pro 10.5 (256 gb)

In a german post I have read that error 4000 possibly can be solved by temp. removing the access code from the iPad (but this Post did not deal with touchid fingerprints).

Good luck and best regards,

With the Apple Configurator 2 method it works much faster and no recovery mode needed. But you need a apple machine for this.

Finder also does not work in many cases.

You are advising people the following: "For everyone reading, this answer is useless. Look for the proper answer in another topic that describes putting your device in recovery mode and updating through iTunes"

I am responding to that advice as it is incorrect. Itunes also works for some but not for all. Or you did you mean something else?

What i dont understand is why Apple is messing up like this and is not capable of fixing this issue after one update (15.0.1) Are they blind? Not reading the complaints everywhere on the internet? Where is Apple support? Not a single reply here from them. A bit shamefull isn't it?

you are not alone. a couple of people reporting this problem. if you have that problem, wifi update is not possible.

I got myself 3 iPads with the problem.

not one iPad was able to update iPadOS, I tried macOS Catalina and BigSur and Windows 10.

at the moment I don't want to reset the iPad's. maybe that would help but can't test it out at the moment.

sadly looks like we have to wait for apple.

Same issue here. I tried everything when updating over WiFi proved impossible. I connected to iTunes on my laptop (Windows 10), and got a “disk full” error message. I did a complete reset to factory settings and got a “device not found” error message. I spent over an hour chatting and speaking to Support, and the best the rep could offer was to suggest I visit my local Apple Store. Clearly, they’re not reading these boards, or others where the same issues are being reported. My gut says 15.0.1 is causing some sort of hardware compatibility issues for Pro users. I guess we’ll just have to wait for a new update to be pushed and hope for the best.

Thank you so much. I’d tried the Apple recommended steps of deleting the update, trying again, same issue when 15.0.2 dropped too. Tried two different Macs but both had a unknown 4000 error message during the update after finishing the back up. But your method of doing it recovery mode has worked a treat. Hopefully the hair I was ripping out grows back.

nobody said "lots or many" so why mention it?

no it doesn't have anything to do with rushing the update server. the package will be downloaded on Mac with no problems.

and all my iPhones have worked with no problem.

server problems are maybe at the same day but in the past it didn't happened on the next day (aside form a bug in the build himself)

so its clear that some iPads seems to have the problem. and the time everyone is updating is not imported.

maybe someone will be on holidays and want to install the last security updates?

I am having the same issue - looking at various online reports it appears Apple forgot it had sold the iPad Pro - the ios 15.0.1 update has a bug with the iPad Pro - it should be supported.

This issue is a first with all my various Apple products - I can only magine Apple have an issue with preparing and completing proper testing across its product estate - i look forward to ios v15.0.2.0.0.1

I don’t have a Mac (need/want one) - so, Configurator is not an option.

Apple OS is strictly controlled (unlike other OS options) - so it should be easier to apply Development and Fixes across the Apple estate without breaking it - sloppy development and testing. We can all expect to see os15.0.2 soon, quickly followed by os15.0.3 - as Apple get a grip on their OS

I had same problem! I tried to install iPad iOS 15.0.1on my iPad Pro 256 Gb not successfully for several times.. Only was showing (Installing) for ever. Finally I found fast_kurs_do’s solution and it works for me. Now I run iOS 15.0.1

Thanks, good job.

No question 15.0.1 is a bad release for some devices. I went through he11 with my 12.9 2nd gen iPad Pro. I don't like 15 that much anyway which is why I have not attempted to install it on my 10.5 iPad Pro.

Its a sad state of affairs when Apples recommended fix is from a user. Ridiculous!

You're not addressing Apple here. This is a user-to-user tech support forum.

If you'd like, please submit your comments/suggestions/requests to Apple directly, using this link:--> Apple – Product Feedback

Thanks and regards

Thanks a lot.

Will try that later :)
