What is ROM?

We all might be learning about the ROM from the first class that it means read-only memory. After that, it has various types of the ROM. 

But in today’s article, we are going to discuss something what actually the ROM is and how to install this ROM on your Android device. 

Whenever you switch on the mobile phone what we see first a booting logo, screen all this is ROM. 

It is a memory where the operating system is situated. Now, when you buy any smartphone there is pre-installed ROM on your Android device. 

Which helps you to use Android operating system. If we check any operating system, any computer or any electronic thing we will see ROM.

What is Stock ROM and Custom ROM

Stock ROM – Stock ROM is something which is pre-installed on your Android device.

It means that this ROM is given by the original company and there will be no much customization and other settings. If you newly buy your Android device so there is a stock ROM already installed on your Android device. 

With some application and skin which is given by the company or by Google and you can’t do any more changes in the mobile like change of themes. 

If you are using stock ROM then there are chances you don’t get updates and if you get updates then there are chances that you won’t be satisfied because of skins which are pre-installed by your manufacturers like Samsung, xiaomi and etc.

Custom ROM – Many of times while using your stock ROM. You might be bored using it. 

Just because you use the same functions again and again and there is no change in the system. You don’t get latest updates on your Android device. 

Which is sometimes worst thing ever Here custom ROM comes and helps you to use a new system and a completely new look for your Android device. 

Which is something which is loved by someone? Because you can enjoy the latest upgrade on your Android device. You can customise your Android with the help of themes. Which is available on play store. 

Easily use them with no issues. You can change the complete look of your Android device without using any kind of external application such as Gravity box.

Sometimes there are bugs in this custom ROMs but you will get regular updates on your Android device. We have also shared about Remotely Turn Off Your Android By Sending an SMS in which you can turn off your android device by a secret code

What Is Flashing Of Custom ROM

Now, Flashing of custom ROM is the term in which you will be changing a complete look of your Android. 

It means if you are using stock ROM then you will be changing the full ROM of your Android device or we can say that software of your Android device. 

Now Flashing this requires some extra knowledge, but I will be teaching you the full procedure. You might be listening about Best Custom ROM for your Android and other updates from Facebook and other places which are really sometimes good to try something new. 

If you are having good support development and many of the developers have bought the same smartphone which you are using so they release some of the best custom ROM by porting the ROM or simply by creating the new Android ROM for your smartphone.

Before flashing the custom ROM on your Android device it is important that you take your Android backup before flashing any custom ROM on your Android device.

What Is Bootloader And How to Unlock It

The bootloader is something which starts Firstly before the system starts. 

Every device has the different Bootloader by depending on Bootloader the developers creates the custom ROM. 

Every Android device has the different Bootloader and even custom ROM so you can install it on your Android device. 

The first thing which starts on any operating system is Bootloader it sends all the commands. If we look at the bootloaders every electronic computer, laptop, Macbook, iPhone all are having the bootloader.

Why do this mobile phones and Android devices having Bootloader in lock state

Android device manufacturers such as Nexus, Sony, Samsung and other manufacturers they think to protect you from using any kind of custom ROM on your Android device.

They just think if the user will unlock your warranty might get void. This is the reason why they give your Bootloader in the lock state.

When you root your Android device what happens is there is a chance that some third-party software may steal your information. They might steal your information such as debit card details or credit card. 

This is the reason why those applications are not available Play Store. Because play store knows this application that this will harm their users and misbehave in terms of security. 

So when you will unlock your Android bootloader you will loose all your phone data from your device. Your mobile phone will be factory reset. Then you can install a custom recovery on your Android device.

What Is Custom Recovery And How Can I install In My Device

Custom recovery is something which will help you to flash custom ROM on your device. Most of the times the company gives you stock Recovery which will help you to format your device when you have accidentally locked it. 

It will be of no use when you have to do any changes to your system. Like Flashing custom ROM on your Android device. So for that you need to have the custom recovery and Flashing procedure of custom recovery is different for different devices. 

Like for Samsung, you need Odin, for Nexus devices you need to have ADB drivers. This is different for all the mobile phones. 

If you want to install the custom recovery on your Android device then you need to follow-up this guide which I have previously shared about flashing recovery and kernels by using a Flashify tool.

Downloading The Best Custom Rom For Your Device.

Now, You have to download the best custom ROM for your Android device. This is the procedure where you have to make sure which ROM you have to install on your Android device. 

Actually, custom ROM is something which you need to be sure that there are no bugs and no issues. If you want me to suggest the best custom ROM for your Android device then I will suggest you use Cyanogen Mod which comes with the best customization and themes which you will really like it. 

We have published some best custom ROM list some months back at that time this Cyanogen Mod was on our first list. Still it is in the first place which is a really good thing about it. 

As we all know Android is an open source in which you can do editing of your own. So here the developers of Cyanogen Mod takes this ROM and work on your mobile phone.

This ROM helps you to do a lot of changes in your system. When you will find the best custom ROM for your Android device save this file on your Android SD card or your internal storage. I was pretty exciting some days back to write about  Customize Your Android Device With Gravity Box
