DUDU-Meng This is exciting update. First i've tried USB tethering and it was completely WORKING right away. After that i've removed the cable, went to WIFI and connected to the iphone while USB tethering was ON, and its still was connected no problem. So for this update both WIFI tethering and USB tethering was working great. Before turning on USB tethering sometimes i still saw IP failure couple of times, but it was still connected 1 out of 3 times, after turning on USB tethering, it was be able to connect all the time. (obviously with cable removed). I will keep watching and testing connection and will update after some time.
P.S. One weird thing that I've noticed right away with this update is that FAN turning ON and OFF every couple of seconds from some reason, (in settings it was set as usual on Auto and 60 degrees). Before it was working correctly, and worked until temperature went below certain threshold (60 degress). So thanks a lot for this update we can use hotspot now!!!
