I succeeded updating via DS. Turn off your PB, open DS, connect it, and when it says 'does bb bla bla bla rebooting bla bla bla, just choose update'
Downloading the whole process again, works 100%, disconnected, and there goes another 22Mb update! SAD
i also succeeded in updating OTA and im in the uk with an american spec playbook. i have never had any issues with updating...always done it OTA on two occassions now so its not an eu problem
