flash a rom to android device

Want to upgrade to the most current and optimized version of Android? Wondering to install a new version of Android on your device for a better Android experience? No worries! The best about Android is the possibility of customizing and optimizing the firmware and through this, the possibility of powering up the performances of our devices. Today, I will teach you how to flash a ROM to your Android phone including Samsung, Sony, HTC, LG and more.

Part 1: What's a ROM?

"ROM" stands for "read-only memory." A custom ROM replaces your device's Android operating system - normally stored in read-only memory - with a new version of the Android operating system. Custom ROMs are different from acquiring root access.

A new ROM can bring you the latest version of Android before your manufacturer does, replace your manufacturer-modded version of Android with a clean, stock version, and take your existing version and just beef it up with awesome new features.

Part 2: How to Flash a ROM to Android Device

Steps below are a general guideline for ROM flashing. You can get the general concept about installing a custom Android ROM but you'll need to do a little search engine exploration to double check on the requirements, quirks, and specific ROM files for the particular phone.

Requirements: Your Android phone should have at least 40-50 percent of battery to perform the flashing process.


How to do:

Step 1: Root Your Device

Root your Android phone. Although you don't actually need to root your phone to flash a ROM, you just need to unlock your bootloader and flash a custom recovery. But most custom ROMs come with root access. Thus root your device in the first step.

Step 2: Backup Your Device

Whenever changing roms, it is a good idea to make a Nandroid or BART backup first. Backup the data which is saved on the internal storage memory of your handset; save everything you might need including text messages, call logs, internet settings, market apps, EFS folder and so on.

Note: In case you lost data without backup, refer to professional Tenorshare Android Data Recovery to recover data after flashing the ROM.

Step 3: Download and Flash the ROM

Firstly find the ROM you want. You may also want to poke around sites like the XDA Developers forums to see what's available for your particular phone. Optional: download the Google apps package if it is not included on the firmware file.

Once you have downloaded these File, mount your phone's SD card and copy there the .zip file. Follow steps below to flash your ROM:
