unknown error occurred (2009)
iPad Pro without notice blacked out, displayed a very small spinning wheel and then powered off. The ipad charged overnight but would not power on. I plugged the ipad into my PC and launched iTunes. ITunes recognised my device in DFU and downloaded then tried to restore the ipad. It failed and returned "unknown error occurred (2009)". Help please!
iPad Pro 10.5-inch, Wi-Fi
