Can you please confirm whether Lumia Software Recovery Tool is also effective for HTC 8s or otherwise? While updating it from Windows 8 to 8.1 it got stuck in Airplane Mode and I was unable to fix the problem even by hard reset. Now it does not wake up, screen is in complete black, but the phone heats up as if it is technically working. When plugged into the socket the notification light blinks for 70 to 80 times, indicating low battery signals, and then disappears automatically. The phone starts heating up as if the battery is charging but nothing happens. If there is any solution, then please let me know.
