Hi guys. My Lumia 525 (WP 8.1 - Lumia Denim) now showing the error "Unable to find bootable option. Press any key to shut down" and it never switch on. I tried to reinstall the firmware and os using updated Windows Device Recovery Tool. After detecting the device it searched for available software on the server and after searching it shows error "Package not available for this device". Plz help guys.
