How to solve Launch X431 IMMO Plus fails to upgrade firmware and device not respond

I tried to update key programming and firmware on the Launch X431 IMMO plus but it failed me, WiFi is good, immo plus tablet said device no response. Any solution?

Solution:

In order to update key programmer software to activate key programmer function menu, you have to connect Launch X431 key programmer.

You cannot update key programming software/firmware without that key maker.
