I have a humzor nexzdas pro, but when I choose to diagnose the car model, the specific car model cannot be displayed on the screen normally. Even if I click on any car brand, it will always prompt "Check permission...please wait" (see below Figure).
For this problem, eobdtool.co.uk 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 Humzor 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.
