Flashing Custom ROMs in Android Device: Being able to install and flash custom ROMS is one of the biggest reason that today so many people are rooting their Android Smartphones. Why stick to the old and monotonous interface of the device, when you can get much more interactive looks as well as much more great tweaks with custom ROMs. You can flash custom ROMs and just sit back and enjoy the interface on your Android Smartphone.
Android is great, but sometimes, the version you get with your phone—whether its vanilla Android or something like Samsung’s TouchWiz—leaves a bit to be desired. Here’s how to install a new version of Android (or ROM) on your device for an even better Android experience. Rooting your device grants you the power of your device. Power to manipulate its Performance and other features.

Make sure the Custom Rom you are flashing is meant for your device or else it can cause boot loopsand soft brick . I’m not responsible for anything that happensto your device while flashing roms.
Prerequisite before installing Custom ROM :
- Download the suitable custom ROM for your device.
- Put the custom rom zip file in your sd card.
- Go To CWM Recovery/TWRP or any other recovery: Switch off the Phone Press and hold ” Volume Up + Power+ Home (Button combinations differs from device to device)” Buttons and Select Recovery Mode by Volume Up . Select Recovery Mode by Volume Down
- Backup: Before installing any rom please make a Nandroid backup of your current rom
For that go to Backup and restore in recovery then click on Backup. So that you if you mess things up then you can easily get back your phone to its previous working state and prevent it from soft brick .

1. The Wipe data and cache doesn’t wipe Contacts?
-> It does wipe everything but your contacts/pictures are synced in your Google Account so they’ll be restored back. Any game progress *might* (don’t quote me) be saved on your SD Card so you might not have a problem. It doesn’t wipe your SD card, just the phone’s data.
2. How to Backup Apps & data?
-> You can use Titanium Backup to Backup system apps and data.
