ROM is the software that runs on the Android devices which is stored in the Read Only Memory. To classify, ROMs are of two types – Stock ROM and Custom ROM.

Custom ROM – This version is developed by a developer or hacker that enables the users to customize their applications or software, thereby improving the performance drastically.

There are both advantages and disadvantages in using custom ROMs for Android devices. Before loading custom ROMs, you need to root your android device. Rooting will help you to change your privilege from “guest” to “super user”. When you buy the device, you will be having only guest privilege since you will not be able to access all the codes as the manufacturer locks it up. It is considered as a protective measure, but the tech savvy’s are disappointed by this action as they cannot use many potential features or update it.

    Hi. If I root my device and bricking occurs can I push my device back to stock ROM?
    In simple is there any way to back from custom ROM to stock ROM?

    • DopeyTheOne says:

      @taha Let’s say that as long as you can power up your phone to go into fastbootmode, you can use adb command in Windows cmd (and SDK installed) to push or pull stuff in or out your device. Only if you damage hardware (ie by screwing around with values of let’s say CPU and blowing the thing to Android heaven), most of the time you can at least flash the stock back. Just remember to ALWAYS make a complete backup before doeing anything. And…oh yeah, always at your own risk. 🙂 Check out XDA dev site, and read and learn, before you burn.

    • Jose says:

      Depends which Custom ROM you choose to use. But most of the custom ROMs increase the overall speed of the device because it gets rid of unnecessary pre-installed apps and free the RAM.
