I have installed the Android Terminal Emulator inside Android Jelly Bean (4.2.2). The device being used is http://www.laptopmag.com/reviews/mini-pcs/rk3188-android-mini-pc. This device has problems connecting over adb to my computer. Am also unable to enter the recovery mode/download mode on this device. Hence I cannot use any of the standard tools for rooting my device. However, I have been able to install the Android Terminal Emulator app inside Android Jelly Bean. Is it possible to root my device from the Android Terminal Emulator. Please guide me.
Is it possible to root a device via some custom system update file put in an SD? Even this could work out for me.
