Flash Android with ROM Manager

Many of u might be curious to know how to flash your Android.
Here is the easiest way to do that.
The Steps
Here are the steps, at a glance. Look the list over and move on to the more detailed explanation of each bullet point.


1. Root Your Phone
2. Install ROM Manager App
3. Back Up
4. Download The ROM You Want To Try
5. Flash It



1. Root Your Phone
The first thing you need to do is root your phone. Don’t be afraid – we already covered this in the Rooting Explained + Top 5 Benefits Of Rooting Your Phone article a few weeks ago, so go ahead and read that first – I’ll wait.
Rooting is usually a 5 minute process, and many guides around the web explain what that process is for your exact phone model and Android version combinations, just Google "YOUR_PHONE_MODEL root".
Now that you have root, let’s proceed to the next step.

2. Install ROM Manager App
This is the easiest step. Go to the Android Market on your phone and install ROM Manager.
This excellent application handles backing up and restoring, as well as flashing new ROMs, all from an easy user interface. This application requires root, which is why we’ve first gone with step 1.
Got the app installed? You should see something like this:


3. Back Up
This part is very easy and in fact I dedicated a whole tutorial just to this subject which you can read if you want more details about the backing up and restoring process.
Done reading the backup tutorial? Now check this out: you don’t even have to perform a manual backup – ROM Manager will automatically ask if you want to back up or not in step 5, when you are flashing the new ROM. This is what it will look like:

3.1. Flash A Recovery Image
If you read the backup/restore article above, you may have seen that there is a one-time step that was needed before ROM Manager, or any other manager, can install ROMs, back up, restore, or do anything with Nandroid Backup – and that is flashing a recovery image.
Important: unplug the USB cable during this step, as some users are reporting problems flashing recovery while plugged in (thanks DennGir and others).

This recovery image contains a boot loader which replaces your original boot loader.
The boot loader gives you the ability to run Nandroid backup and restore commands outside of the OS.
It also lets you install ROMs but we will not do that today. Since the OS cannot back itself up fully while running, ROM Manager will reboot into this boot loader to perform Nandroid operations.




Again, remember: this step needs to be done one time only.

4. Download The ROM You Want To Try And Copy It To Your Phone’s SD Card
Here is where you need to do a bit of research and find the ROM image you want to put on your phone. If you don’t know exactly what you’re looking for, again, Google can help you – just search for "YOUR_PHONE_MODEL ROM" and look around.

Download The ROM You Selected

5. Flash It
The process of installing new firmware or low-level system software in general is called flashing.
