Just retried Kingo root app version 1.3.5 and have been able to get root, I think! Need someone else to try. When I ran the app the first time it failed, but I noticed it now installs an app on the phone. When I connect to PC, launch the app on the phone then run the program on PC I get root success. It does go away after boot, but seems to be holding as long as you don't, again this is where I need confirmation. So far, es file explorer has asked for root and has been granted, system app mover also gets root but does not seem to go any further. Also, every few seconds I get toast messages saying these apps have been granted root, whether they are running or not. Again, someone with more experience might be able to get this working better. Hopefully someone is still checking this forum!
