Jailbroken iPhone 5 iOS 8.3 Barclays App Issue?

I have a previously jailbroken mobile phone. Chris removed. Resets all factory settings. Reset all network settings.

However, I still get the mobile pop up message stating the Barclays app will not support jailbroken devices? Any ideas how I can fully clear my device of traces of the jailbreak without full restore? (My Mac is too full to back up my phone with no more room to delete so full reset and wipe is not ideal)

I have googled many times but can't really see an answer that works.

I meant Cydia removed not Chris removed
