This seems to be a pointer: java.lang.RuntimeException: java.lang.NoSuchFieldException: TRANSACTION_setApplicationRestrictions

Not sure if that means the exploit has been fixed or needs to be triggered differently?

Nothing in dmesg, no reboot. App just closes immediatly after opening, nothing to see on screen really.
