How to Solve Lonsdor K518 Pro Failed to Copy File Problem?

Customer problem:

I wanted to upgrade the system of my Lonsdor K518 Pro. But I couldn’t finish the upgrade. Why? My network was fine. I tried many times but it still didn’t work, and appeared the error message “Failed to Copy File”.

UOBDII.com engineer replied:

This is a kernel upgrade failure. There is no need to upgrade the kernel. If there is a problem, the Lonsdor Tech will send the kernel upgrade file, and you need to use manual files to do it.

Now you just need to update your K518 Pro Key Programmer by one-click update as follows.

1.Select “One click update” on the main menu

2.Select “One click update” in the next interface

3.Start downloading database

4.Wait a while till the upgrade process is completed.
