Phone reboots when I connect it to my pc via usb I have a Medion P5015 and I've tried rooting it with Kingroot and Kingoroot together with the pc and android versions but to no avail. Now when I try to connect my phone to my pc with the provided data cable the screen freezes as soon as I plug it in. Soft buttons hard buttons do nothing after a few seconds it reboots to the boot screen but goes to a black screen and goes back to the boot screen and goes on. When I unplug it during this stage it cuts off then I have to manually power it on with the power button, quite absurd if you ask me.
I find that Rooting and such causes unforeseen problems. I am trying to learn to keep everything stock and update when they are available. It is very hard sometimes to resist the temptation.But usually there are negative results down the road. I would rest my phone to factory by going to >Settings>Backup &amp; reset>Factory data reset>Reset phone. It will pop up a confirmation click yes and the phone will then reboot and continue the Reset from recovery mode.
