What is ROM and How to Choose Perfect ROM For My Android Device

You’ve been with your no-longer-so-brand-new Android phone for a long time now. It has become slow, there are apps that are no longer compatible with your operating system version and widgets and do not convey any emotion.

If your phone was a PC, you would have formatted and installed latest operating system. Same thing goes with Android, where you have to install ROM on device.

What is an Android ROM? What about firmware?

Firmware and ROM are one and the same thing: Read-only memory on your phone, can be said to be Soul of your Phone. Contains the Google Android operating system, duly adapted and configured to work with the hardware-specific mobile phone (antenna, computer graphics, cameras, etc.).

The operating system is in a read-only memory for two reasons: to prevent overwriting files, and to keep you faithful to small changes and integrated applications that manufacturers often include in their models. Being open source, Android allows for all sorts of modifications. In addition to the official ROM, very common thing you find is ROM made ??by groups of volunteers and enthusiasts who take the code base and add or remove features or skins. Even you yourself can create (cook) yours.

So why should I change the ROM?

For the same reason you changed your phone, whatever. Some people need more performance, who want to upgrade the operating system to a later version without waiting for official update, and who wants to renew the look of your phone or just try new things.

Is it Dangerous? Can Anything go Wrong?

No. Generally nothing happens as long as we follow the steps given correctly. Chances are new ROM may wipe out user data so, take backup (Titanium Backup is recommended). Or it may happen that some of your apps aren’t compatible with new ROM so, there are always alternatives to choose from million in Android Market.

Bricking of Phone (Phone actually becomes no more than a brick) is an extreme case which results out of carelessness and improper following of instructions.

How to flash a ROM?
