I have a Sony xperia Z (C6603). A while back I rooted the device but then later I did a factory reset and unrooted it. Sadly I have forgotten exactly what software I used for rooting/unrooting.
Now the phone works perfectly for everything I do except for my Barclays Bank app which declares "Sorry, the Barclays Mobile Banking app does not support rooted devices".
I have tried mutilple root-detection utilities and they all insist the device is no longer rooted.
Is there anything I can do to fix this?
