该示例：我有一个nexus 7，我扎根于运行4.1.1（果冻bean jro03d）可以只刷一个自定义内核， 说这个 http://forum.xda-developers.com/showthread.php？ t = 1831780 ， 在我的股票rom上使用时光恢复？抱歉，如果这是显而易见的，但我只在自定义ROM上确实完成了它，我找不到Interwebs的明确答案
The General Question: Is it possible to install custom kernels on a Rooted Stock ROM?
The Example: I have a Nexus 7 which I have rooted running 4.1.1 (Jelly Bean JRO03D) would it be possible to just flash a custom kernel, say this one http://forum.xda-developers.com/showthread.php?t=1831780, on my stock ROM using Clockwork Recovery?
Sorry if this is obvious, but I've only really done it on custom roms, and I couldn't find a definite answer on the interwebs
Yes, it is possible to install custom kernels on stock roms. The kernel developer will usually say which roms (or types of roms) the kernel supports. If you are not sure you can try reading the kernel thread, and there will always be poeple saying things like "working great on [firmware version here]". This way you can also make sure that it will work ok on your version of the stock rom.
As for your example, yes you can flash this on your stock rom: xda-developers
Yes. You can flash a custom kernel on your stock ROM, but it has to be the appropriate kernel i.e. it has to be the version the kernel supports. In this case you will be limited to overclocking only. However, you can download setcpu, nofrills, voltage control, cpu contol, etc to enjoy max.
