How to Solve Humzor NexzDAS Pro Bluetooth 9.6inch Tablet Cannot Select Car Model?

Customer problem:
I have a Humzor NexzDAS Pro Bluetooth 9.6inch Tablet. It can turn on normally, when I want to select the car model to diagnose, I can tap the car maker, but the specific car model cannot appear on the screen normally. It always prompts “inspection permit…please wait” (see the fig. as below) even though I tap any car brand.

For this problem, professional technicist offers the related suggestion:
The possible cause is that you click frequently during the operation so that the firmware of VCI cannot work normally.

The NexzDAS APP on Humzor NexzDAS Pro tablet is unable to brush the firmware of VCI, but smartphones can do it.

Please try to use the following methods to solve.
Method 1: Download NexzDAS APP from Google Play on your Android smartphone to test again
Method 2: Turn off the software on HUMZOR NexzDAS Pro and pull out the VCI, then open the software and insert the VCI for testing. It is equivalent to resetting the software in the VCI.
