Hi! A friend of mine is looking for me to root his Kurio 7s tablet (I haven't heard of it, either), and it looks like it uses stock or similar Android. The version is 4.2.2. Curious as to whether or not I can use stock ROMS or if there is a custom for the specific device. Thanks for the help!
For ROMs, the ROM has to be written for the specific device, there's no such thing as a stock ROM for all Android devices. The stock ROM is the one that comes with the device, and there are other ROMS that developers develop - for that device. The chances are that no one is going to write a ROM for one of those little $50 devices.
