Hi,

my HTC has rebooted badly (battery issue)

The following reboot acted like a 1st android boot, and all settings were lost, but not files and apps. Anyway i've had to put setting in apps

Bitcoin app wallet was still there, but not the wallet content and history.

When i browse the folder /data/de.schildbach.wallet folder, it's empty. i'm not root in the phone.
I'm not developper, but taken a look @ MODE_PRIVATE in Java, can it be the explanation ? how to recover ?

thanks for your help
