Good day, I'm new and not very experienced, I had a raspberry pi 2 in the attic, to use it in some way I installed on a 32-gigabyte sd card I had (and7_1-rpi2_3-23022017), everything went well, it works well just that I do not have the reboot and shutdown buttons, there is the possibility to install apk to do this but asks me for administrator permissions, do you know how to do to root the system? I tried to install kingroot install but it does not work, there is a special procedure for this machine to proceed to root, if you know the way there is a tutorial around detailed to proceed? Thanks for the reply.
