Root Your Phone
The first and foremost thing you need to root your phone. Rooting is actually 5 minutes process and many guides around the web explain what that process is for your exact phone model and Android version combinations.
Install ROM Manager App
This is the easiest step which you have to do. Go to the Android market and install ROM Manager. This application instructs backing up and restoring as well as flashing new ROM, all from an easy user interface.
Before doing anything you need to create a backup. This is the safety net if anything goes wrong.You don’t even have to perform a manual backup, ROM manager will automatically ask if you want to back up or not.
Download The ROM
- Here is where you need to do a bit of research and find the ROM image you want to put onto your phone.
- Download the ROM image, which is usually a zip archive, and copy it into the root folder of your SD card.
Important: You do not unzip the .zip file, just copy it as is.
You can do it by
- Attaching the phone with a USB cable and selecting the option of mounting the SD card to be used as a drive on the computer.
Flashing the NEW ROMs
The process of installing new firmware or low level system software in general is called Flashing.
Following steps are
- Open the ROM manager and click Install ROM from SD card
- The ROM you downloaded in previous step should show up in the list. If it doesn’t, make sure you’ve put it into the root folder of th SD card.
- Click on the ROM and you should receive a popup inviting you to
- Backup existing ROM
- Wipe data and cache, which you should only do if you want to do a clean install
- The ROM being installed
The flashing process should take 5-10 minutes installing everything and then 10-20 minutes during the first boot. Please be patient during this process.
Once the phone boot, you will find yourself in new ROM.
Problem During Flashing
If after the “Reboot and Install” step, you immediately get a picture of Android with a big exclamation point, most likely it means the ROM image you downloaded was not cryptographically signed by the developer.
You can fix this problem by:
- Click the exclamation point screen, which goes to the Clockwork Mod recovery menu
- Select the option Install Zip from SD card
- Toggling the “toggle signature verification” option to turn the verification off
- Giving flashing another try by selecting “choose zip from sdcard” and selecting the right ROM.
Install and load up the ROM Manager app in the custom ROM you flashed. Now use the “manage and restore backups” menu to find your backups and restore it.
After you’ve done restoring, you’ll be back to original OS.
