I had the same issue on my cube iwork10 i15-tc but I easily resolved it. I try to restore my tablet with i15-t files downloaded from techtablets, the installation goes well. Then I realised that the touchscreen dindn’t work at all. I tried to reinstall touhscreen drivers but it was no helpful. The solution is pretty simple cause the problem itself is pretty simple: at 99% you installed the wrong installation files for your cube iwork 10 model. For example i had the i15-tc with type-c connector. Your topic saved me (http://techtablets.com/forum/topic/files-for-i15t-restore/) infact i found the i15-tc installation files in there. After installing the correct files the touchscreen restarted to work. So you have to check the model of your device entering on your cube bios. After you find out your device’s model,find the correct files for your model on your own topic. Please let me know if it worked,it worked for me.
