I installed the atv 3 update, and after some days i installed the atv 4 flash. installation ran over correctly, the atv rebooted some times but now, all i get is the introductory clip and the apple logo. No way to get over. Remote not working. If i reboot, it is the same.
Please tell me what to do and, what to do to at least replace the atv 3 firmware.
