Kingroot 4.1 does NOT work on the Pop Icon A564C.
I tried initially clearing data as mentioned but it always started the process over from 0% then rebooted at 20%.
When I didn't clear it, it resumed at 20% after the first rebooting, got to 21% leading to a second reboot then showed that it had failed to root, saying: "Root failed. No strategy now" and let me sent a report.
