Hi , I've change an HDMI/DR setting in developer option on my X9S and now It starts but I see ony some colored dots ! No image both in HDMI both in AV ! How can I enter in recovery mode to make a hard reset?? Or is better to flah it ? To resolve simply Install the new OTA 2.0.15 or I must flash a full image ? Where can I find the full image to flash ?
