Why can't I overclock my Android after I rooted it?

dniblock

I went to the "trouble" of rooting my old LG Android phone, with the goal of removing all the bloatware that was installed by my carrier and overclocking the CPU. I rooted it successfully, then after I got superuser privileges I was able to remove the unwanted programs (Hurray!), but after I installed SetCPU I was unable to change the CPU speed from the factory setting (Boo!). What am I missing? Why can't I change the CPU speed now that I've rooted the device?

You still have the stock kernel, and it won't allow overclocking.  You will need to flash a custom ROM.  There are plenty of choices out there, but be aware that flashing a new ROM is not nearly as easy as rooting an android device.  I would estimate that the first time will take a you couple of hours to carefully go through the process if it is completely new to you.  There is also a possibility that you can brick your device, so be certain that you accept that before you start, back up everything, and carefully read through the entire process multiple times before you start.  I would check out Android Central, and look in the forums section for your device.  I'm not sure which LG you have, but there are some really active LG forums, particularly for the Optimus variants, so if you happen to have one of those you really are in luck.

 

You have taken the first step with rooting to really discovering what is great about Android devices, assuming that you are the type of person who likes playing around to optimize your device to do exactly what you want it to do.  Make it faster, remove bloatware, upgrade to a newer version of Android OS, whatever you want.  It is not for everyone; one of my good friends that is mod crazy in almost every aspect of his life uses an iPhone because, as he put it, "I just want one thing that works well without me messing with it."

 

Again, you can brick your device, but that is pretty unlikely if you are careful and READ, READ, READ before you start.  Good luck!

"So you want to know about rooting your Android phone, eh? Yeah, it sounds a little scary. It's kind of a big leap, and it may involve a few steps. and quite possibly the use of a command prompt, which would require you to follow instructions and type words and stuff.

Here's rooting in a nutshell: Your Android smartphone is based on Linux. A big, bad, scary computer operating system known only by people with neck beards. (Only, not really. But mostly.) Anyhoo, Android apps need permission to access certain parts of Linux, and not all apps have this special "root" access. That includes a few basic things, like the camera flash, and the ability to take screen shots. There are a bunch of other apps that need root access for other reasons, too, but the basic premise is the same.

So should you root your phone? First thing to do is read this editorial, and decide if you want to go further. Then if you're the type who loves to mess with things, go for it. If you want to squeeze a little more functionality out of your phone, go for it. Need more convincing? Check out "Rooting Q&A -- Is it for me?"
