One customer reported that he tried to update Xhorse VVDI2 firmware by Xhorse Upgrade Kit, but the “Upgrade button” became grey, and he could not update successfully.
Xhorsetool.com engineer replied:
The possible cause is that the version of Xhorse Upgrade Kit is too old.
Please use the latest version to update firmware.
