Flashing Custom ROMs on 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 great performance tweaks with custom ROMs.
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.
If you want to know more about rooting and Installing custom ROMS you can check this post about Rooting to Installing Custom ROM. Before reading this Make sure you have unlocked bootloader and TWRP or any other Recovery installed in your device. If you have a Mediatek Device you can make your own CWM & install in just 5 mins by this method CWM for Mediatek
Prerequisite before installing Custom ROM
- 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.
- Charge your device upto 60% to avoid any shutdown or low battery warnings while flashing the ROM.
- Download the suitable custom ROM for your device.
- Put the custom rom zip file in your device’s Internal Storage.
- Go To 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.

FAQs
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 and FlashFire (ADB over WiFi) Backup to Backup and Restore system apps and data.
3. What is TWRP Recovery?
TWRP is a powerful tool that gives control over the phone without needing to boot into Android. It can be used to flash a ROM or use minor app mods, as well as to create and manage backups. Stock recovery doesn’t allow any installation of 3rd party zip files. In order to install any other zip which is not signed by the firmware manufacturer, we need to install TWRP Recovery.
4. Can I install TWRP without root?
Yes, you can install TWRP without root, if you have unlocked your bootloader of your device.
5. Is it possible to wipe internal storage through TWRP?
Yes, it is possible to wipe internal storage through TWRP.
