Hello,
I'm working with vuforia SDK 1.5.9 on Xcode 4.2 on both an iPad v3 under iOS 5.1.1 and an iPhone 4 under iOS 5.1.1.
Everything went very well until today. For a reason that I tried to track down, all projects using the SDK are now broken on and only on the iPad v3. All is nice on the iPhone 4.
With a fresh install, when I run ImageTargets sample, I see this in the console :
2012-12-02 23:58:23.378 ImageTargets[463:707] APPSTATUS_LOAD_TRACKER

2012-12-02 23:58:23.932 ImageTargets[463:4007] QCARutils: Failed to load any target
I tried everything : throw derived Data away from Xcode (even from the Finder), trash the app on the iPad, redownload the SDK, resart the iPad and the Mac, I even tried to manipulate the loading process in the QCARUtils class to check the path at serveral points, then thrashed everything again, installed from scratch again and again... But no way, it always fails ONLY on the iPad!!
What's going on ? How could it be so different all of a sudden on the very same device in just a few seconds ? Everything was working well, then the second after everything is broken without any big change (the samples freshly downloaded are bugging!!).
Do anyone have an idea about that ? I spent almost all my day to understand what's the cause of this bug, but I give up here.
Can someone give me some hint ?
Thanks

You already have the datasets as these are included in the samples. Every single vuforia project gives me this same error on this iPad, even freshly downloaded samples.

Ok - understood.
Thanks for clarifying.

Well, I did restore the iPad to have a fresh install and it is working now. I also restored my previous apps and setting after a first test, and it is still working now.

Glad to hear it's working.
However it's unlikely that the failure was caused by Vuforia as millions of people have run thousands of apps without this happening.
Sometimes devices just need a reset.

Hi
I tried this on a range of different devices and was unable to reproduce the problem.
Are you finding that it is it specific to iOS6.1?

I've just 'witnessed' a similar problem albeit on a handset a few thousand miles away from me. As far as I can tell the app ran fine until a day or so ago, then suddenly started reporting this dataset error.

Could you please let me know which handset it was along with OS version?
Also, have you tried the built-in samples? Do they exhibit the same behaviour?
Next up, have you tried your app with the default dataset?

Hi Nalin,
We've reproduced the problem using the 'off the shelf' ImageTargets app.

Thanks MoLotus,
A few questions:

We have confirmed:
That leaves us with a full reload of iOS and restore of content, unless you have other suggestions.

Hi MoLotus,
Thanks for the update, and the clarification.
How many reports are there of this now?

Hello,
as I still have the same problem, I hope the update on wednesday will fix it.
Thank you Nalin.

I did not say I would provide updated software - far from it.
I meant an information update only.

FYI - after iTunes failed to restore their iPhone, our NY colleague took their phone to the retailer who restored it for them and lo, apps with Vuforia inside now work as intended.

Thanks for the update MoLotus,
We are trying to find a way forward as I am sure you can understand ;)
Hopefully someone will be in touch with you shortly.
