When using KESS V2 V2.10 Software, you need pay attention to following tips:
1. Please Do remember to disconnect internet when install the software or using the device, otherwise it will prompt update, update will damage our device.
[If your device was damaged because of updating, you need to reflash the CPU program, and then copy and paste the software to the TF card again. Then you must install the software on another laptop again]
