I have rooted a smart phone without bricking it, but that was with a couple three premade kernels to update with and can not find any for this make or model tablet.
I want to build a android 4.4 kernel for my iRola DX752 7" tablet (formerly known as a Kocasco M752) using Eclipse ADT etc. but I am practically a newbee at this. I figure if I brick it I am only out $50. It currently runs Android 4.2.2 with system updates that I can't count on bringing me up to more current releases, and it runs a Rockchip RK2926 Cortex-A9 CPU with 512MB RAM, 2GB internal SD and a 16GB external SD card.
