If you’re looking for How to flash a android phone for free, there are several ways to go about it. When we talk about flashing phones, we also mean reprogramming them. Android OS was designed for extreme customization. One who knows the steps properly can safely turn their old android phones into brand new ones.

Step 1: Backup your phone’s data to your computer

This is the most important step in the process of flashing. If you fail to backup your data, you will lose them after flashing. You can find backup apps on the Play Store. Look for Titanium Backup and Helium to backup the data to your computer and you can restore it later.

Step 2: Unlock Bootloader/ Root your phone 

In order to flash your phone with a custom ROM, you need to change your bootloader settings. Bootloader is the same as BIOS on a computer. Unlocking bootloader varies from phone to phone. Once you’re done unlocking the bootloader, you should root your phone. Rooting an android increases the chance of successful flashing of ROM. Apps like Kingo, SuperSU Pro Root App are good apps to root your phone.  

Step 3: Download custom ROM

If you haven’t already, select and download the ROM of your choice. The most popular ones are CyanogenMod, Paranoid, Carbon, and MIUI. You might be wondering how to flash a phone without a computer, but we’d suggest you download the ROM to your computer and then move it to your phone. Alternatively, if you don’t want to use a computer, you may use an app named ROM Manager; it will automatically download different ROMs to your phone.

Step 4: Boot phone into recovery mode

To boot phone into recovery mode, hold Volume Down + Power button. That will take you to bootloader. Once there, you’ll have to use your phone’s volume buttons to navigate through. Use Power button to select and enter recovery. Step 5: Flashing ROM to your android phone

Step 5: Flashing ROM to your android phone 

Once in recovery mode, you can select from a few options such as wipe, install, settings, backup etc. Navigate to install using the volume buttons and use power button to select it. On the next screen, choose ‘Install zip from sdcard’. Find the location where you have the ROM, and confirm the installation by swiping the button at the bottom of your screen.

Preparing your device

Before you can flash a build to your device, you must prepare your device:

  1. Enable Developer options and USB debugging.
  2. Enable OEM Unlocking in the Developer options menu. If your bootloader is already unlocked, this option is grayed out with Bootloader is already unlocked.
  3. If you're having trouble enabling OEM Unlocking, make sure:
       (a) Your device is connected to the internet. 
       (b) Your device has checked in with Google, which may not be the case just because your device     recently connected to the internet. To force a check in, enter *#*#CHECKIN#*#* (*#*#2432546#*#*) in the Dialer (no SIM required). After entering the number (no need to press call), the text disappears and a success notification appears.

  3. Allow the flash tool to communicate with your test device through adb by accepting the popup that says Allow site access to your ADB keys in order to communicate with devices.
  4. Click Add new device.
  5. Select your device from the list and click Connect. This list may not contain the full device name.
  6. On your device’s screen, select Always allow from this computer and click OK to accept the USB debugging connection.
